Hazard Communication



AGENCY: Occupational Safety and Health Administration (OSHA), 

Department of Labor.



ACTION: Advance Notice of Proposed Rulemaking (ANPRM).



-----------------------------------------------------------------------



SUMMARY: OSHA, other Federal agencies, and stakeholder representatives 

have participated in long-term international negotiations to develop a 

Globally Harmonized System of Classification and Labeling of Chemicals 

(GHS). The GHS has been adopted by the United Nations, and there is an 

international goal for as many countries as possible to implement the 

GHS by 2008. The GHS includes harmonized provisions for classification 

of chemicals for their health, physical, and environmental effects, as 

well as for labels on containers and safety data sheets (SDS). Adoption 

of the GHS by OSHA would require modifications to the Agency's Hazard 

Communication Standard (HCS). For example, an order of information 

would be established for safety data sheets. In this notice, OSHA is 

providing further information about the GHS, the benefits of adopting 

it, and its potential impact on the HCS. OSHA is seeking input from the 

public on a number of issues related to implementation of the GHS. The 

Agency is simultaneously announcing the availability of a new guide on 

its Web site at http://www.osha.gov that describes the GHS.

I. Background



A. History of the OSHA Hazard Communication Standard



    OSHA's Hazard Communication Standard (HCS) (29 CFR 1910.1200; 

1915.1200; 1917.28; 1918.90; and 1926.59) was first adopted in 1983 for 

the manufacturing sector of industry (48 FR 53280; November 25, 1983). 

Later, the Agency expanded the scope of coverage to all industries 

where employees are potentially exposed to hazardous chemicals (52 FR 

31852; August 24, 1987). The HCS requires chemical manufacturers and 

importers to evaluate the hazards of the chemicals they produce or 

import. The rule provides definitions of health and physical hazards to 

use as the criteria for determining hazards in the evaluation process. 

The information about the hazards and protective measures is then 

required to be conveyed to downstream employers and employees by 

putting labels on containers and preparing and distributing safety data 

sheets. All employers with hazardous chemicals in their workplaces are 

required to have a hazard communication program, including container 

labels, safety data sheets, and employee training. (Note: The HCS uses 

the term ``material safety data sheet'' or MSDS, while the GHS uses 

safety data sheet or SDS. For convenience, safety data sheet or SDS is 

being used throughout this document.)

    OSHA has updated estimates in the standard's regulatory impact 

analysis, and found that the HCS now covers over 7 million workplaces, 

more than 100 million employees, and some 945,000 hazardous chemical 

products. Ensuring that hazard and protective measure information is 

available in workplaces through hazard communication programs helps 

employers design and implement appropriate controls for chemical 

exposures, and gives employees the right-to-know the hazards and 

identities of the chemicals, as well as allowing them to participate 

actively in the successful control of exposures. Together, these 

actions of employers and employees reduce the potential for adverse 

effects to occur. The information transmitted under the HCS 

requirements provides the foundation upon which a chemical safety and 

health program can be built in the workplace.

    The HCS is performance-oriented, i.e., it establishes requirements 

for labels and safety data sheets but does not provide the specific 

language to convey



[[Page 53618]]



the information or a format in which to provide it.



B. OSHA Involvement in the Development of the GHS



    OSHA's HCS is designed to disseminate information on chemicals to 

users to precipitate changes in handling methods and thus protect those 

exposed to the chemical from experiencing adverse effects. Since the 

United States (U.S.) is both a major importer and exporter of 

chemicals, the manner in which the U.S. and other countries choose to 

regulate information dissemination on hazardous chemicals not only has 

an impact on the protection of employees in the U.S. but also may pose 

potential barriers to international trade in chemicals.

    To protect employees and members of the public who are potentially 

exposed to chemicals during their production, transportation, use, and 

disposal, a number of countries have developed laws that require 

information about those chemicals to be prepared and transmitted to 

affected parties. These laws vary with regard to the scope of chemicals 

covered, definitions of hazards, the specificity of requirements (e.g., 

specification of a format for safety data sheets), and the use of 

symbols and pictograms. The inconsistencies between the various laws 

are substantial enough that different labels and safety data sheets 

must often be developed for the same product when it is marketed in 

different nations. For example, Canada has established requirements for 

labels under its Workplace Hazardous Materials Information System 

(WHMIS). WHMIS requires that labels include specified symbols within a 

defined circle. U.S. chemical manufacturers must label chemicals 

accordingly for marketing in Canada.

    Within the U.S., several regulatory authorities exercise 

jurisdiction over chemical hazard communication. In addition to OSHA's 

HCS, the Department of Transportation (DOT) regulates chemicals in 

transport, the Consumer Product Safety Commission (CPSC) regulates 

consumer products, and the Environmental Protection Agency (EPA) 

regulates pesticides, as well as having other authority over labeling 

under the Toxic Substances Control Act. Each of these regulatory 

authorities operates under different statutory mandates, and have 

adopted varying approaches to hazard communication requirements.

    The diverse and sometimes conflicting national and international 

requirements can create confusion among those who seek to use hazard 

information effectively. For example, labels and safety data sheets may 

include symbols and hazard statements that are unfamiliar to readers or 

not well understood. Containers may be labeled with such a large volume 

of information that important statements are not easily recognized. 

Given the differences in hazard classification criteria, labels may 

also be incorrect when used in other countries. This is particularly 

true with regard to workplace hazard communication in the U.S. Since 

the U.S. OSHA system is performance-oriented, labels meeting the 

specification requirements of other countries are often seen in the 

U.S. workplace. While there are no format requirements in the U.S. that 

are violated by these differing formats, the underlying hazard criteria 

from another country may be different and that could make the 

information on the labels out of compliance with the U.S. HCS.

    Development of multiple sets of labels and safety data sheets for 

each product when shipped to different countries is a major compliance 

burden for chemical manufacturers, distributors, and transporters 

involved in international trade. Small businesses may have particular 

difficulty in coping with the complexities and costs involved.

    When the HCS was first issued in 1983, the preamble included a 

commitment by OSHA to review the standard regularly to address 

international harmonization of hazard communication requirements. OSHA 

was asked to include this commitment in the final rule in recognition 

of an interagency trade policy that supported the U.S. pursuing 

international harmonization of requirements for chemical classification 

and labeling. The potential benefits of harmonization were noted in the 

preamble:



    * * * [O]SHA acknowledges the long-term benefit of maximum 

recognition of hazard warnings, especially in the case of containers 

leaving the workplace which go into interstate and international 

commerce. The development of internationally agreed standards would 

make possible the broadest recognition of the identified hazards 

while avoiding the creation of technical barriers to trade and 

reducing the costs of dissemination of hazard information by 

elimination of duplicative requirements which could otherwise apply 

to a chemical in commerce. As noted previously, these regulations 

will be reviewed on a regular basis with regard to similar 

requirements which may be evolving in the United States and in 

foreign countries. (48 FR 53287; November 25, 1983)



    OSHA was the only Federal agency that had a public commitment to 

pursue harmonization. We have actively participated in a number of such 

efforts in the years since that commitment was made, including 

participation in trade-related discussions on the need for 

harmonization with major U.S. trading partners. The Agency also issued 

a Request for Information (RFI) in the Federal Register in January 

1990, to obtain input regarding international harmonization efforts, 

and on work being done at that time to develop a convention and 

recommendation on safety in the use of chemicals at work in the 

International Labor Organization (55 FR 2166).

    Little progress was made regarding international harmonization 

until June 1992, when a mandate from the United Nations Conference on 

Environment and Development (UNCED) (Chapter 19 of Agenda 21), 

supported by the U.S., called for development of a globally harmonized 

chemical classification and labeling system:



    A globally harmonized hazard classification and compatible 

labelling system, including material safety data sheets and easily 

understandable symbols, should be available, if feasible, by the 

year 2000.



    UNCED further noted that an internationally harmonized system for 

transport of dangerous goods was already available. However:



    * * * [G]lobally harmonized hazard classification and labelling 

systems are not yet available to promote the safe use of chemicals, 

inter alia, at the workplace or in the home. Classification of 

chemicals can be made for different purposes and is a particularly 

important tool in establishing labelling systems. There is a need to 

develop harmonized hazard classification and labelling systems, 

building on ongoing work.



    This international mandate initiated an extensive effort to develop 

the GHS. It involved numerous international organizations, many 

countries, and extensive stakeholder representation. The work was 

managed by the Coordinating Group on the Harmonization of Chemical 

Classification Systems, under the umbrella of the Interorganization 

Programme for the Sound Management of Chemicals. OSHA chaired the 

international coordinating group that managed the harmonization work. 

The technical work was divided among several international 

organizations. Development of criteria for health and environmental 

hazards, as well as mixture classification for chemicals having these 

hazards, was done under the auspices of the Organization for Economic 

Cooperation and Development (OECD). Criteria for physical hazards were 

based on the already harmonized criteria for transportation, and 

developed by the United Nations Subcommittee of Experts on the 

Transport of Dangerous Goods and the International Labor



[[Page 53619]]



Organization. The overall management of the process, as well as the 

work on aspects of the system for communicating hazards on labels and 

safety data sheets, were done by the International Labor Organization. 

OSHA participated in all of this work, and took the U.S. lead on 

classification of mixtures and hazard communication.

    The negotiations were extensive and spanned a number of years. The 

primary approach involved identifying the relevant provisions in each 

of the major existing systems, developing background documents that 

compared, contrasted, and explained the rationale for such provisions, 

and undertaking negotiations to find an agreed approach that addressed 

the needs of the countries and stakeholders involved. The major 

existing systems were those of the U.S., Canada, and Europe, and the 

United Nations Recommendations for the Transport of Dangerous Goods. 

Principles to guide the work were established, including an agreement 

that protections of the existing systems were not to be reduced as a 

result of harmonization. Thus countries could be assured that the 

existing protections of their longstanding systems would be maintained 

or enhanced in the resulting harmonized approach.

    In the U.S., an interagency committee under the auspices of the 

U.S. Department of State coordinated the various agencies involved. In 

addition to the four core agencies that have requirements that are 

potentially impacted by the GHS, there were a number of other agencies 

involved that had interests related to trade or other aspects of the 

GHS process. Different agencies had the lead in various parts of the 

discussions. Positions for the U.S. in these negotiations were 

coordinated through the interagency committee. Interested stakeholders 

were kept informed through e-mail dissemination of information, as well 

as periodic public meetings. The U.S. Department of State also 

published a notice in the Federal Register that described the 

harmonization activities, the agencies involved, the principles of 

harmonization, and other information, as well as invited public comment 

on these issues (62 FR 15951; April 3, 1997). Stakeholders also 

actively participated themselves in the discussions in the 

international organizations and were able to present their views 

directly in the negotiating process.

    The product resulting from this effort, the Globally Harmonized 

System of Classification and Labeling of Chemicals (GHS), was formally 

adopted by the new United Nations Committee of Experts on the Transport 

of Dangerous Goods and the Globally Harmonized System of Classification 

and Labelling of Chemicals in December 2002. In 2003, the adoption was 

endorsed by the Economic and Social Council of the United Nations. 

While the GHS has been adopted, it is considered to be a living 

document that will be updated as necessary to reflect new technology 

and scientific developments, or provide additional explanatory text. 

OSHA expects to propose adoption of the 2005 version, Revision 1. 

Modifications to the GHS that are made after the GHS is adopted in the 

U.S. would require additional rulemaking.

    It should be noted that the GHS document consists of non-mandatory 

recommendations and explanatory text. It is not a model regulation or a 

standard that is to be adopted verbatim. Countries like the U.S., and 

agencies such as OSHA, will propose converting the recommendations into 

appropriate regulatory text consistent with national requirements while 

ensuring that the specific provisions are consistent with the GHS and 

thus harmonized. OSHA expects to propose modifying the HCS to address 

the changes in hazard criteria, adopt the specific labeling 

requirements, and adopt the SDS order of information. Other parts of 

the framework of the HCS (such as the coverage of articles, trade 

secrets, and scope) would likely remain the same.

    While the GHS text is available to everyone on the UN Web site, it 

will be the proposed rule to adopt the GHS that OSHA plans to issue 

rather than the detailed GHS document that will be of primary interest 

to U.S. stakeholders. To help those who are not familiar with the 

approach in the GHS, OSHA has prepared a guide that summarizes the GHS 

requirements, and it is available on our Web site (click on the Hazard 

Communication button on http://www.osha.gov). In addition, the Agency 



also has a detailed comparison of the HCS to the GHS available on the 

Web site so that interested parties can review the types of changes 

that would need to be made for the current U.S. workplace requirements 

to be harmonized with the international approach.

    A review of these differences reveals that the primary impact of 

revising the HCS to adopt the GHS would be on compliance obligations 

for producers of hazardous chemicals. The modifications to the HCS 

would involve a review of the classifications of these chemicals, as 

well as preparation and distribution of new labels and revised safety 

data sheets. Employers who use chemicals, and exposed employees, would 

benefit from receiving the revised labels and safety data sheets 

prepared in a consistent format. The information should be easier to 

comprehend and access in the new approach, allowing it to be used more 

effectively for the protection of employees. The primary change in 

workplaces where chemicals are used but not produced will be to 

integrate the new approach into the workplace hazard communication 

program, including assuring that both the employers and employees 

understand the pictograms and other information provided on the 

chemicals.

    The GHS is now available for worldwide implementation, and 

countries have been encouraged to implement the GHS as soon as 

possible, with the goal of a fully operational system by 2008. This 

goal was adopted by countries in the Intergovernmental Forum on 

Chemical Safety, as well as endorsed by the World Summit on Sustainable 

Development. In addition, countries involved in the Asia-Pacific 

Economic Cooperation have endorsed a goal of 2006. The U.S. 

participates in all of these international groups, and has agreed to 

working toward achieving these goals.

    The U.S. is also a member of both the United Nations Committee of 

Experts on the Transport of Dangerous Goods and the Globally Harmonized 

System of Classification and Labeling of Chemicals, as well as the 

Subcommittee of Experts on the Globally Harmonized System of 

Classification and Labeling of Chemicals. These permanent UN bodies 

have international responsibility for maintaining, updating as 

necessary, and overseeing the implementation of the GHS. OSHA and other 

affected Federal agencies actively participate in these UN groups. In 

addition, OSHA, EPA and the U.S. State Department also participate in 

the GHS Programme Advisory Group that functions under the United 

Nations Institute for Training and Research (UNITAR). UNITAR is 

responsible internationally for helping countries implement the GHS, 

and has ongoing programs to prepare guidance documents, conduct 

regional workshops, and implement pilot projects in a number of 

interested nations.



C. Other OSHA Activities Related to the GHS



    OSHA and the other three core agencies continue interagency 

discussions related to coordination of domestic implementation of the 

GHS, in addition to ongoing discussions and coordination related to 

international work to implement and maintain the GHS.



[[Page 53620]]



    OSHA also has ongoing activities related to the GHS under the North 

American Free Trade Agreement (NAFTA) discussions on handling of 

hazardous substances, and in discussions with the European Union on 

issues related to the global management of chemicals.

    In addition, a number of organizations with whom OSHA has Alliances 

have expressed an interest in hazard communication, and in working 

together with each other on the subject. The Alliance program is a 

cooperative program that enables organizations committed to 

occupational safety and health to work with OSHA to prevent injuries, 

illnesses, and fatalities in the workplace (click on the Alliances 

button on OSHA's home page for an explanation of the program and a list 

of participants). One of the issues they have identified to work 

together on is related to the GHS, and making the business case for GHS 

adoption, particularly for small businesses. OSHA has conducted a 

roundtable of Alliances interested in this topic, and will continue 

these meetings to get their input and work with them on products they 

identify as appropriate for development. Products under consideration 

include a document addressing frequently asked questions and the 

corresponding answers, as well as a document that addresses why the GHS 

is needed.



D. Benefits of the GHS



    Development of this system required extensive work by a great 

number of people, and resources from many countries and organizations. 

The reason it received such support is that there is a widespread 

belief that there are significant benefits associated with 

implementation of a globally harmonized approach to hazard 

communication. Countries, international organizations, chemical 

producers and users of chemicals will all benefit.

    First and foremost, implementation of the GHS will enhance 

protection of people potentially exposed to chemicals and the 

environment. While some countries such as ours already have the 

benefits of protection under existing systems, the majority of 

countries do not have such comprehensive approaches. Thus 

implementation of the GHS will provide these countries with the 

important protections that result from dissemination of information 

about chemical hazards and protective measures. In our country, we 

expect that adoption of the GHS would improve and build on protections 

we already have. Refinement of the information provided would help 

improve comprehensibility and thus make it more likely that the 

information will result in workplace changes to protect employees. As 

has already been noted, the majority of affected employers and 

employees should benefit from adoption of the GHS through receipt of 

better, more standardized, and consistent information about chemicals 

in their workplaces.

    Secondly, implementation of such an approach would facilitate 

international trade in chemicals. It will reduce the burdens caused by 

having to comply with differing requirements for the same product, and 

allow companies that have not had the resources to deal with those 

burdens to be involved in international trade. This is particularly 

important for small producers who may be precluded currently from 

international trade because of the compliance resources required to 

address the extensive regulatory requirements for classification and 

labeling of chemicals.

    Third, one of the initial reasons this system was pursued 

internationally involved concerns about animal welfare and the 

proliferation of requirements for animal testing and evaluation. Where 

existing systems have different definitions of hazards, it often 

results in duplicative testing to produce data related to the varying 

levels of toxicity or cut-offs used to define the hazards in the 

different systems. Having one agreed definition will reduce this 

duplicative testing. It should be noted that OSHA has no testing 

requirements. The HCS is based on collecting and evaluating the best 

available evidence on the hazards of each chemical.

    Information transmittal systems provide the underlying 

infrastructure for the sound management of chemicals in a country. 

Those countries that do not have the resources to develop and maintain 

such a system can use the GHS to build their chemical safety and health 

programs. Unlike some other safety and health issues, a country's 

approach to the sound management of chemicals definitely affects other 

countries. In some cases, bordering countries may experience pollution 

and other effects of uncontrolled chemical exposures. In all countries, 

there is a need to acquire sufficient information to properly handle 

the chemical when it is imported from other countries. Thus having a 

coordinated and harmonized approach to the development and 

dissemination of information about chemicals will be mutually 

beneficial to both importing and exporting countries.

    In the U.S., the four primary regulatory agencies (OSHA, EPA, CPSC, 

and DOT) that would be responsible for GHS implementation are not 

domestically harmonized in terms of definitions of hazards and other 

requirements related to classification and labeling of chemicals. Thus, 

if all four agencies adopt the GHS, the U.S. would have the additional 

benefit of harmonizing the overall U.S. approach to classification and 

labeling. Since most chemicals are produced in a workplace and shipped 

elsewhere, every manufacturer deals with at least two of the U.S. 

systems. Thus every producer is likely to experience some benefits from 

domestic harmonization, in addition to the benefits that will accrue to 

producers involved in international trade.

    OSHA believes that adoption of the GHS could also address some of 

the issues that have been discussed in the U.S. regarding the HCS and 

its implementation, such as improving labels and SDS comprehensibility 

through implementation of a standardized approach. The current 

regulatory system includes a performance-oriented approach to labels 

and SDSs, allowing the producers to use whatever language or format 

they choose to provide the necessary information. This often results in 

a lack of consistency that makes it difficult for some users of 

chemicals to properly identify the hazards and the protective measures, 

particularly when purchasing the same product from multiple suppliers. 

Having the information provided in the same words and pictograms on 

labels, as well as having a standardized order of information on SDSs, 

would help all users identify the critical information necessary to 

protect employees.



E. State Plan States



    If Federal OSHA promulgates a final rule amending its HCS in 

response to the GHS, the 26 States and U.S. Territories with their own 

OSHA-approved occupational safety and health plans would be required to 

revise their standards to reflect the new amendment within six months 

of Federal promulgation. 29 CFR 1953.5(a). A revised State hazard 

communication standard must be applicable to both the private and 

public (State and local government employees) sectors. Some States may 

have statutory provisions that would require amendment in order to 

conform to a revised Federal HCS.

    Section 18(c)(2) of the OSH Act requires that State standards 

applicable to products distributed or used in interstate commerce, if 

not identical to the Federal standard, must be required by compelling 

local conditions and must not unduly burden interstate



[[Page 53621]]



commerce, in addition to being ``at least as effective'' as the Federal 

standard. The amended HCS, like the original standard, would be 

`applicable to products' in the sense that it would permit the 

distribution and use of hazardous chemicals in commerce only if they 

are in labeled containers accompanied by safety data sheets[.]'' 48 FR 

53280, 53323, November 25, 1983. In order to assure that State 

standards do not pose an undue burden on interstate commerce, and to 

advance the goals of the GHS, OSHA would expect to closely scrutinize 

resultant State standards to assure not only equal or greater 

effectiveness, but also that any different or additional requirements 

do not conflict with, or adversely affect, the effectiveness of the 

national application of OSHA's standard.



II. Provisions of OSHA's HCS and the GHS



A. Scope of the GHS



    The GHS covers chemicals in various stages of their life cycle, 

from production to disposal. It is based primarily on the hazards of 

chemicals. The GHS is designed to allow regulatory authorities to 

choose provisions that are appropriate to their particular scope of 

regulation. This is referred to as the ``building block approach.'' The 

GHS includes all of the building blocks or possible regulatory 

components that might be needed for classification and labeling 

requirements in the workplace as well as for regulation of 

classification and labeling of pesticides, chemicals in transport, and 

consumer products. Therefore, regulatory authorities such as OSHA would 

choose the provisions of the GHS that are necessary for the protection 

of employees, but would not adopt others that address other types of 

protection. For example, the GHS includes harmonized criteria for 

classifying chemicals for aquatic toxicity. Since OSHA does not have 

the regulatory authority to address environmental concerns, OSHA would 

not adopt the GHS criteria for aquatic toxicity. It is expected that 

other U.S. agencies that regulate environmental issues will consider 

adopting this definition. Similarly, the GHS safety data sheet format 

includes a section that addresses environmental information. OSHA would 

not require inclusion of environmental information for SDSs used in 

workplaces.

    The building block approach may also be applied in other ways when 

deciding which parts of the system to adopt. For example, the GHS 

includes classification criteria, labels, and SDSs. While workplace 

authorities such as OSHA are likely to adopt all of these elements, it 

is expected that consumer product authorities will not have SDS 

requirements, nor will transport authorities. The building block 

approach may also be applied to the criteria for defining hazards. For 

example, the acute toxicity criteria are much broader than those we 

currently have in the HCS for workplace exposures. This is to allow 

consumer product authorities the tools they need to address the 

protection of children who might accidentally be exposed. OSHA would 

not need to adopt all of the categories of acute toxicity in order to 

protect employees from the types of exposures they may have.

    In addition to the building block approach, the GHS also contains a 

number of areas that are left to the competent authority to determine 

how to apply the provision. Where OSHA is the competent authority, 

i.e., in terms of workplace protections in the U.S., the Agency expects 

to maintain its current approaches in terms of interpretations and 

accommodations regarding application. These approaches are based on the 

rulemaking record, as well as implementation experiences in the U.S., 

and have been determined to be an appropriate application. For example, 

the scope and application provisions in the GHS address the interface 

of the OSHA requirements to requirements in other agencies that address 

the same products. These scope interpretations are expected to be the 

same if OSHA adopts the GHS.

    Overall, the scope of the GHS with regard to chemicals covered, as 

well as types of chemicals and workplaces that are covered, is very 

similar to the HCS. The HCS has a very broad scope of coverage, 

ensuring that information is provided on all potential hazards in 

American workplaces. Adoption of the GHS should maintain this broad 

coverage of hazards and chemicals. It should be noted that the GHS, 

like the HCS, does not require any new testing of chemicals. 

Evaluations of chemical hazards are to be based on the best available 

evidence.

    As has been described above, the HCS consists of requirements for 

defining health and physical hazards, preparing a written hazard 

communication program, preparing and distributing labels on containers 

that are shipped as well as containers in the workplace, preparing and 

distributing safety data sheets for all hazardous chemicals, and 

employee training. The GHS addresses classification of health and 

physical hazards, and preparation and distribution of labels and safety 

data sheets. It does not include requirements for a written hazard 

communication program or for employee training. Training is noted in 

the GHS as an important adjunct to label and safety data sheet 

requirements, but the harmonization process did not include such 

provisions. Countries are thus free to determine what training will be 

applicable in their own regulatory approach. OSHA believes that 

training is critical to ensuring the effectiveness of hazard 

communication, and anticipates maintaining current HCS requirements 

that training be part of a hazard communication program. OSHA also 

expects to propose some additional training to ensure understanding of 

the new approach regarding labels and SDSs in the GHS.



B. Definitions of Hazards Covered



    The HCS covers a broad range of both health and physical hazards. 

The standard is performance-oriented, providing definitions of hazards 

and parameters for evaluating the best available evidence to determine 

whether a chemical has a hazardous effect under the standard. In 

particular, with regard to health hazards, one toxicological study, 

conducted according to established scientific principles and reporting 

a statistically significant adverse health effect, is sufficient for a 

finding of hazard under the rule. The principle behind the standard is 

that it is to address dissemination of information, and thus complete 

information about all of the potential hazards should be disseminated 

to ensure that employers and employees can make appropriate decisions 

about the level of protection required in their particular workplaces. 

Hazard information, in combination with information about the exposures 

occurring in each workplace, allows decisions to be made by employers 

regarding the appropriate risk management to implement based on the 

specific conditions in their workplace. Chemical manufacturers and 

importers do not have information about the exposures to their products 

in each workplace where their product may be used, so they must prepare 

their labels and safety data sheets based on the hazards of the 

chemicals.



C. Health Hazards



    The HCS thus covers every type of health effect that may occur, 

including both acute and chronic effects. The standard describes 

different systems of the body and indicates that target organ effects 

are to be considered in the hazard evaluation. The definitions provided 

are indicative of the wide range of coverage, but are not exclusive.



[[Page 53622]]



Any type of adverse health effect that is reported and substantiated by 

a scientific study is covered. The standard specifically includes the 

following in the definition of ``health hazard'':



Carcinogens

Toxic or highly toxic agents (all routes of entry)

Reproductive toxins

Irritants

Corrosives

Sensitizers

Hepatotoxins

Nephrotoxins

Neurotoxins

Agents which act on the hematopoietic system

Agents which damage the lungs, skin, eyes, or mucous membranes



    The GHS also has a very broad approach to the range of health 

effects covered:



Acute toxicity (any route of entry)

Skin corrosion/irritation

Serious eye damage/eye irritation

Respiratory or skin sensitizer

Germ cell mutagenicity

Carcinogenicity

Reproductive toxicity

Specific target organ systemic toxicity--single exposure

Specific target organ systemic toxicity--repeated use

Aspiration hazard



Under the GHS, each hazard or endpoint as listed above is considered to 

be a hazard class. The classes are generally sub-divided into 

categories of hazard. The definitions of hazards are much more specific 

and detailed than what is in the HCS. For example, under the HCS, a 

chemical is either a potential carcinogen or it is not. The evaluation 

is a yes or no response. Under the GHS, there are two categories of 

carcinogenicity, based on the weight of the evidence involved. The 

hazard communication consequences of this classification also vary as a 

result for each category in a hazard class. The hazard communication 

elements allocated to each category reflect the degree of severity of 

the hazard.

    There are advantages to this more specific and delineated approach. 

First, the detailed criteria for classification should lead to more 

accurate hazard determinations and more consistency among multiple 

classifiers. There is less likely to be room for different 

interpretations of the same data. This addresses some of the concerns 

that have been raised about the HCS. In addition, introducing 

categories gives an indication of the degree of severity of the hazard. 

This is helpful to employers and employees determining what the 

appropriate course of action should be when exposures to the chemical 

occur.

    There may be some changes in what the hazard of certain chemicals 

is determined to be based on a consideration of the data available on a 

chemical in light of these new criteria. It is expected that chemical 

manufacturers and importers will be required to re-evaluate their 

chemicals according to the GHS criteria. But given the current broad 

nature of the HCS, it is not expected that the number of chemicals 

covered would change in any significant way. The most likely difference 

would be that the chemical may be characterized in categories for 

certain hazards based on the weight of the evidence.

    With regard to mixtures of chemicals, the HCS requires the 

evaluation of mixtures to be based either on data for the mixture as a 

whole, or, where that is not available, the mixture's health hazards 

are to be based on the presence of ingredients with health hazards over 

a specified percentage. That percentage is 0.1% for carcinogens, and 

1.0% for all other types of health effects. The HCS also recognizes 

that risk may remain below these cut-offs, and where there is evidence 

that is the case, the mixtures are still covered.

    The GHS has what has been described as a tiered approach to mixture 

evaluation. The first step is consideration of data on the mixture as a 

whole, similar to the HCS. The second step allows the use of ``bridging 

principles'' to estimate the hazards of the mixture based on 

information about its components. For example, if a chemical is 

considered to be acutely toxic, but it is diluted with something that 

is not toxic, the GHS allows the employer to take the dilution into 

consideration when evaluating the hazards of the product rather than 

simply basing it on a percentage cut-off approach like the HCS. This 

extrapolation of data will mean that fewer mixtures will be evaluated 

on the basis of the presence of a chemical above a specific cut-off. 

The third part of the tiered approach does involve cut-offs, but they 

vary by the type of effect. In particular, for acute effects, there is 

a formula for determining whether the mixture is considered to be 

toxic. The formula is based to some extent on one that is currently 

used in transport.

    Overall, the approach is generally consistent with the current HCS 

requirements, but provides more detail and specification and allows 

more extrapolation of data available on the components of a mixture--

particularly for acute effects. It is thus more complicated than the 

approach in the HCS, and it is likely that additional guidance, 

particularly electronic tools, may need to be made available to assist 

with compliance.

    As a result of these differences in health hazard criteria and the 

accompanying approaches to classifying mixtures, another provision of 

the standard that is potentially impacted by adoption of the GHS is the 

process of hazard determination. Under the current rule, this process 

is performance-oriented, allowing for a significant degree of 

professional judgment on the part of the hazard evaluator. No specific 

procedures are provided, but there are certain parameters established. 

The scientific literature must be reviewed, and if there is at least 

one toxicological study, conducted according to established scientific 

principles, and providing statistically significant results indicating 

an adverse health effect, this hazard must be disclosed under the HCS.

    The HCS also includes references to sources of information that 

were identified in the rulemaking record as one basis for making an 

initial determination of hazard. Among these listed sources are OSHA's 

substance-specific standards (those chemicals for which OSHA has 

promulgated a permissible exposure limit (PEL) in Subpart Z, Toxic and 

Hazardous Substances), American Conference of Governmental Industrial 

Hygienists (ACGIH) Threshold Limit Values (TLVs), International Agency 

for Research on Cancer (IARC) monographs, and the National Toxicology 

Program (NTP) list of carcinogens. These sources provide employers a 

list of hazardous chemicals. However, manufacturers and importers are 

still required to review the available information to determine 

specifically what the hazards of these chemicals are, and to disclose 

them on labels and safety data sheets.

    The GHS provides much more specific criteria for defining health 

hazards than the HCS does. If OSHA adopts the GHS, these more specific 

criteria will be part of the HCS. This will eliminate the need for a 

specific listing of hazardous chemicals as part of the hazard 

determination procedures. Chemical manufacturers and importers are much 

more likely to make consistent hazard determination evaluations 

following the specific criteria in the GHS, thus addressing the 

concerns that led to the inclusion of lists in the original Hazard 

Communication Standard. References to the chemicals for which there are 

ACGIH TLVs, and those chemicals addressed in IARC Monographs and the 

NTP lists, would no longer be specifically addressed in the HCS. 

Chemical manufacturers and importers would retain the



[[Page 53623]]



responsibility for evaluating all relevant data on the chemicals they 

produce or import.

    Similarly, the provisions for disclosing the hazardous ingredients 

of mixtures under the GHS are much more detailed than the HCS. The 

simple across-the-board cut-offs for all types of hazards would no 

longer be part of the rule if it is changed to adopt the GHS. Modifying 

the HCS to align with the GHS would also eliminate the current 

references to ACGIH TLVs as part of the mixture provisions.



D. Physical Hazards



    With regard to physical hazards, the current definitions in the HCS 

are drawn from other standards we have that address such chemicals 

(e.g., flammable chemicals), or from what were the DOT criteria for 

physical hazards at the time OSHA promulgated the HCS. OSHA includes 

definitions for the following physical hazards in the HCS:



Combustible liquid

Compressed gas

Explosive

Flammable (aerosol, gas, liquid, solid)

Organic peroxide

Oxidizer

Pyrophoric

Unstable (reactive)

Water-reactive



The GHS includes criteria for the following physical hazards:



Explosives

Flammable (aerosol, gas, liquid (including combustible liquid), 

solid)

Oxidizing (liquids, solids, gases)

Gases under pressure

Self-reactive substances and mixtures

Pyrophoric (liquid, solid)

Self-heating substances and mixtures

Substances and mixtures which in contact with water emit flammable 

gases

Organic peroxide

Corrosive to metals



DOT subsequently changed their criteria to be consistent with the 

international transport requirements. The international transport 

requirements for classification of physical hazards have now been 

incorporated into the GHS. While DOT must make a few changes to be 

consistent with the GHS, their requirements are mostly already the 

same.

    OSHA is not harmonized with current DOT requirements. Changing the 

HCS to adopt the GHS criteria would also ensure that DOT and OSHA 

requirements are consistent. This is an important improvement in the 

current situation where the outside of a truck may be placarded with a 

different hazard than the workplace labels convey on the containers 

inside the truck. Again, chemical manufacturers and importers would 

have to re-evaluate their chemicals according to the new criteria in 

order to ensure they are classified appropriately. However, if they are 

chemicals that are transported, i.e., not produced and used in the same 

workplace, this classification should largely be done already for 

purposes of complying with DOT's existing transport provisions. This 

should minimize the additional work required to review the physical 

hazard classifications to be consistent with the GHS for purposes of 

workplace classification and labeling.

    One issue of concern is whether OSHA should also propose to change 

the physical hazard definitions in other standards when it proposes to 

change the HCS criteria to be consistent with the GHS. For example, if 

the HCS definitions are changed with regard to the definition of 

flammable liquids, there is a concern as to whether definitions in the 

flammable liquids standard need to be changed as well, and what the 

impact of this would be beyond classification and labeling. This is one 

of the areas that needs to be further explored in terms of impact and 

possible consequences.



E. Labels



    The HCS requirements for labels simply indicate the minimal 

information required to be on them. At the time the standard was 

promulgated, OSHA reviewed the current industry consensus standards for 

labels, and basically focused on requiring information that was not 

generally present on most labels in use by industry. The additional 

information included an identity that could be traced to more detailed 

information, and specific information about both the health and 

physical hazards. In particular, OSHA did not consider a label 

statement indicating possible harm but no specific health effect to be 

a sufficient hazard communication. Other types of information such as 

precautionary statements were not included in the requirements.

    This performance-oriented approach was strongly supported by the 

chemical industry at the time the standard was adopted. Taking such an 

approach allowed existing labels to continue to be used in many 

situations, thus minimizing the impact on a number of producers.

    However, it also has resulted in labels that are not consistent, 

and may not communicate adequately to users. While some producers 

follow voluntary industry consensus standards, others do not. Many 

large companies have developed their own libraries of phrases to be 

used on labels and safety data sheets, and undertaken translation of 

them into multiple languages. This is a considerable burden for a 

company to develop and maintain.

    Other major existing systems considered in the harmonization 

process included specific label phrases to convey hazards and other 

information. Symbols and pictograms were also part of these systems. 

For purposes of developing an agreed harmonized approach, it was thus 

necessary to consider including such elements in the GHS.

    For each class and category of hazard under the GHS that OSHA is 

considering adopting, there is a harmonized hazard statement, a signal 

word, and a pictogram specified. This is referred to as the core 

information for a chemical. Thus once an employer classifies a 

chemical, the GHS provides the specific core information to convey to 

users on that chemical. There are provisions to allow supplementary 

information as well so the chemical manufacturer is not limited to the 

specified core information. This should address product liability 

concerns for U.S. employers and ensure they can include other 

information they consider to be necessary for that purpose. 

Precautionary statements are also provided as examples in the GHS, but 

they have not yet been agreed and harmonized. This is expected to occur 

in the future as work on the system continues. Figure 1 is an example 

of how the core labeling elements (harmonized hazard statement, signal 

word, and pictogram) are assigned in one hazard class covered under the 

GHS.

    These labeling provisions will likely be the biggest difference 

between the HCS and the GHS. There are benefits to this standardized 

approach. First, employers and employees will be given the same 

information on a chemical regardless of the supplier. This consistency 

will improve communication of the hazards. It may also improve 

communication for those who are not functionally literate, or who are 

not literate in the language written on the label. Literacy of both 

types is a significant concern in American workplaces. Secondly, having 

the core information developed already, translated into multiple 

languages, and readily available to whomever wishes to access it, will 

eliminate the burden of chemical manufacturers and importers developing 

and maintaining their own such systems. Thus the specification approach 

should be beneficial both to



[[Page 53624]]



the producers and the users of chemicals.

    United Nations Globally Harmonized System of Classification and 

Labeling of Chemicals, First Revised Edition, 2005, Annex I. Diamond 

frames for pictograms in the top row are red.

    The use of symbols and pictograms will require some training and 

familiarization to be effective. One of the issues OSHA is considering 

is whether generic training on this aspect of the GHS can be developed 

and made available to employers and employees.

    There is another significant benefit that will be achieved by 

adopting a system that has harmonized hazard statements in it. 

``Control banding,'' a guidance approach to recommending control 

measures for chemical exposures, is attracting significant attention 

around the world. The approach uses information that is readily 

available to small and medium-sized employers with chemicals in their 

workplaces to provide them with workplace-specific control 

recommendations. Basically, the system uses such information to 

estimate the degree of severity of the hazard and the amount of 

chemical present, and relates that to the degree of control needed. The 

control banding approach relies on harmonized hazard statements to 

allow the system to estimate the degree of severity of the hazard. 

Initially based on the European hazard classification system, it has 

now been converted to the GHS phrases. The use of control banding to 

provide guidance for chemical safety and health approaches in U.S. 

workplaces cannot be accomplished until harmonized hazard statements 

are readily available. Adoption of the GHS and its phrases would open 

up the possibility that control banding guidance can be used in the 

U.S. to help small and medium-sized employers select and implement 

appropriate control measures. In addition, the possibility of 

addressing control banding recommendations in GHS SDSs in the section 

on controls is also being explored. For more information on control 

banding, please see http://www.cdc.gov/niosh/topics/ctrlbanding/.





F. Safety Data Sheets



    Under the HCS, the SDS is the detailed reference source on the 

chemical. While labels provide a quick snapshot to remind employers and 

employees of the hazards of the chemical, the SDS addresses all aspects 

of hazard information as well as methods for handling and use. The HCS 

specifies what information must be included on the SDS, but does not 

specify a format or order of information. Again, this approach was 

supported by producers to minimize the impact of the standard for those 

who already developed and disseminated SDSs. Currently, safety data 

sheets under the HCS are required to include:



Identification of the chemical or hazardous ingredients of a mixture

Physical and chemical characteristics

Health hazards, including signs, symptoms, and medical conditions 

that could be aggravated by exposure

The primary routes of entry

The OSHA permissible exposure limit, ACGIH Threshold Limit Value, 

and any other recommended exposure limits

Whether the chemical is considered to be a carcinogen by OSHA, the 

International Agency for Research on Cancer, or the National 

Toxicology Program

Precautions for safe handling and use

Control measures

Emergency and first aid procedures



[[Page 53625]]



Date of preparation of the safety data sheet

Contact information for the responsible party



    Users of chemicals have always preferred a standardized approach. 

Many believe that having the information in the same place on every 

data sheet allows them to access it more effectively. OSHA published a 

request for information regarding ways to improve the information 

provided under the HCS (55 FR 20580; May 17, 1990), and received around 

600 comments in response. The majority of them were in favor of a 

standardized format or order of information.

    As a result of the users' expressed preferences, chemical 

manufacturers in the U.S. developed a voluntary industry consensus 

standard that included an order of information for safety data sheets 

(ANSI Z400.1). This approach was later adopted into international 

voluntary industry consensus standards as well.

    The HCS allows any format to be used, so many producers have been 

following the consensus standard order of information for some years. 

In negotiating the GHS, it was decided that this format should be 

adopted there as well. One change was made, reversing the order of 

sections 2 and 3 so the hazard information appeared earlier in the 

sheet than information on chemical composition. Both the national and 

international industry consensus standards are being changed to be 

consistent with this approach. The GHS data sheet is to include the 

following in this order:



Identification

Hazard identification

Composition/information on ingredients

First aid measures

Firefighting measures

Accidental release measures

Handling and storage

Exposure controls/personal protection

Physical and chemical properties

Stability and reactivity

Toxicological information

Ecological information

Disposal considerations

Transport information

Regulatory information

Other information



    Having a standardized order of information should improve 

comprehensibility, which has been a continuing issue with regard to 

safety data sheets. It should also make it easier for chemical 

producers to comply by providing them with a template to follow. Using 

the industry consensus standards should also minimize the burden of 

preparing new safety data sheets since many chemical producers already 

use the format specified. While the GHS safety data sheet does not 

address exposure limits in the titles of the sections, guidance on what 

should be included indicates that occupational exposure limits would be 

addressed under the ``exposure controls'' section. Countries may choose 

what to require in these sections in terms of occupational exposure 

limits, but it is anticipated that OSHA would require the PELs to be 

included.

    Under the auspices of the International Program on Chemical Safety 

(IPCS), a series of over 1300 international chemical safety cards has 

been developed and translated into 14 languages. These cards are 

developed and peer reviewed by participating institutions in a number 

of countries, including the U.S. The National Institute for 

Occupational Safety and Health (NIOSH) is undertaking this work. The 

cards are similar to SDSs in terms of the information provided, but 

they are in a concise format of two pages. The cards are going to be 

updated to reflect the GHS criteria and hazard information. They may be 

found on NIOSH's Web page at: http://www.cdc.gov/niosh/ipcs/nicstart.html

 OSHA also has a link to them on our hazard communication 



page. These cards are an excellent resource for many of the most common 

chemicals found in the workplace. When updated to be GHS-consistent, 

they will also be a useful resource for GHS compliance and for 

implementation of control banding.

    As mentioned earlier, there is information required on a GHS SDS 

that is outside OSHA's jurisdiction to regulate. This includes 

environmental and transport information. We do not intend to propose 

requiring it on safety data sheets, but will provide information about 

the provisions so chemical producers can include it if they wish to be 

completely consistent with the GHS. OSHA does not preclude such 

information being on a safety data sheet, but will not review or 

enforce such provisions.



III. Public Resources for Further Information on the GHS



    OSHA has a safety and health topic page on hazard communication 

available as part of our Web site. There is a hazard communication 

button on the Agency's home page (http://www.osha.gov) that leads to a 



portal page on the topic, including a box on the GHS. There is a page 

devoted to the GHS that is reached through clicking on this box. It 

gives additional background information, and has links to the GHS 

official text, Web pages of other U.S. agencies, international 

organizations, and countries involved in GHS implementation.

    As noted earlier, a substantive guide to the GHS is available on 

this page to describe the system in more detail for those who are 

interested. There is also a detailed comparison of the HCS to the GHS 

that notes the areas of difference that would have to be addressed in 

adopting the GHS.



IV. Request for Input



    In order to prepare for rulemaking proposing adoption of the GHS 

and modification of the HCS to accomplish that, OSHA is seeking input 

from the public on a number of issues related to implementation. This 

information will be used by OSHA to prepare cost analyses and other 

documents required to support the rulemaking. These requests are 

divided into several categories of information below. Please provide 

comments, evidence, data, and other input for those categories that 

affect you or for which you have relevant information. The details for 

submitting this information are specified in Section V.

    Current situation. Modifying the HCS to adopt the GHS would have 

the greatest impact on chemical manufacturers, importers, and employers 

who produce or distribute hazardous chemicals as currently covered 

under the HCS. In order to be harmonized, the hazard classifications of 

each product will need to be reviewed according to the classification 

criteria of the GHS, and new labels and safety data sheets will have to 

be prepared.

    1. How many hazardous chemicals as defined by the HCS do you 

produce, import or distribute? How many hazardous chemicals do you 

export? How many different labels or data sheets do you need to prepare 

for each chemical you export?

    2. Who is responsible for reviewing the data on chemicals and 

preparing appropriate labels and safety data sheets? What is their 

professional background? Do you make independent determinations or rely 

largely on labels or data sheets developed by others (suppliers, 

materials available on the Internet, etc.)?

    3. How long does it take on average for each hazardous chemical to 

complete the review and prepare new labels and safety data sheets? How 

much does it cost for each chemical product? Please break down the cost 

for the classification, preparation of a new label, and revision of a 

safety data sheet.

    4. Would the time required to prepare a GHS SDS be more, less, or 

about the same as currently required for preparing an SDS? What time 

and costs would be required to convert existing SDSs to the



[[Page 53626]]



GHS format? Would the costs depend on the amount of time allowed for 

the conversion process?

    5. Please describe any electronic tools you have to assist with 

this process, such as systems that classify chemicals or prepare labels 

or safety data sheets. How long would it take to update those systems 

to make them GHS-consistent?

    6. How many of your employees receive hazard communication 

training? How many hours of training at what frequency (on hire, 

annually, as needed, etc.)? How long would it take to teach employees 

to recognize GHS pictograms? Would more standardized labels and SDSs 

make it easier to use the available hazard communication information?

    7. What savings will you incur when you only have to classify a 

chemical once instead of multiple times depending on how many agencies 

and countries are involved? What other benefits do you anticipate?

    Timing. As has been noted, the international goal is for as many 

countries as possible to adopt the GHS by 2008. Since OSHA has 

longstanding requirements for labels and safety data sheets, the Agency 

expects to allow a significant phase-in period for compliance in order 

to give people sufficient time to review their classifications and 

amend them as necessary, and subsequently revise labels and safety data 

sheets to reflect the new requirements. It seems probable at this point 

that the revised requirements could potentially be in place by 2008, 

but the phase-in period for compliance may have to extend beyond that 

time period.

    8. What is a reasonable time period for phasing in the 

modifications? Should the phasing be done by size of business? Are 

there any other factors that should be considered to differentiate the 

phasing?

    9. What is the normal cycle for updating labels and safety data 

sheets?

    10. Do you have stockpiles of product that are already labeled? How 

long will those stockpiles last?

    11. Do you have any other information or data that would help OSHA 

determine the appropriate phasing in of the new requirements or other 

issues related to timing?

    Technical issues. As discussed, the scope of hazards covered by the 

GHS is similar to that of the HCS. OSHA anticipates adopting all of the 

health and physical hazard criteria in the GHS. Definitions in the HCS 

will need to be the same as the GHS in order to be harmonized. However, 

there are some determinations that are left to countries to decide in 

terms of whether all categories and all hazards are adopted.

    12. Are there any health or physical hazards that are currently 

covered by the HCS that you think are not adequately addressed in the 

GHS criteria? What are they and why do you think they are not 

adequately addressed? Are there any health or physical hazards that 

aren't covered in either the HCS or the GHS that should be added?

    13. In addition to references to hazardous chemicals with OSHA 

PELs, should OSHA propose to include any other listing of hazardous 

chemicals when aligning the hazard determination provisions of the HCS 

to the GHS? Should OSHA propose that the mixture provisions only 

reference exceeding the OSHA PEL when revised to adopt the GHS? Should 

OSHA propose deleting the requirement that the ACGIH TLV be included on 

the SDS when the requirements are changed to be consistent with the 

GHS? Should other recommended exposure limits be included on the SDS?

    14. Within the health hazard criteria, are there any categories of 

hazard that should not be adopted in the HCS? For example, should OSHA 

adopt all of the categories addressed in the acute toxicity criteria? 

If not, what categories would be appropriate to address anticipated 

workplace exposures?

    15. If OSHA changes the HCS to adopt the physical hazard criteria, 

how will that impact other OSHA standards that use the same criteria as 

the HCS? Does OSHA need to change those criteria at the same time the 

HCS is changed? Storage and handling requirements for flammable liquids 

are one example that has been identified as a potential problem if 

different definitions apply, and information on a safety data sheet is 

linked to the definition in the HCS but not consistent with other 

definitions.

    16. Are there any other technical issues that need to be considered 

in adopting the GHS? Please explain.

    Compliance Assistance and Outreach. OSHA is interested in getting 

input on the types of materials or products that would assist employers 

in understanding whatever modifications OSHA makes to the HCS to adopt 

the GHS, and to help them achieve compliance. To this end, we would 

like to get input now on the types of outreach that would be most 

helpful. As has been noted, there are some explanatory documents that 

are already available on OSHA's Web site.

    17. What products would be most useful to employers? Employees? Do 

you prefer paper publications? Electronic tools?

    18. What subjects would be of most interest? Classification 

criteria and procedures for substances and mixtures? Labels? Safety 

data sheets?

    19. What is the best way to distribute the materials to reach 

affected employers and employees?

    20. Are there any types of materials that would be especially 

appropriate for small businesses? Most small businesses would be users 

of chemicals, rather than producers, so they will be receiving labels 

and safety data sheets prepared according to the new approach. Are 

there training materials that would be helpful to learn or teach about 

the new approach? In particular, would training on symbols or 

pictograms be of use?
