National Advisory Committee on Occupational Safety & Health


NACOSH was established under the Occupational Safety and Health Act of 1970 to advise the secretaries of labor and health and human services on occupational safety and health programs and policies. Members of the 12-person advisory committee are chosen on the basis of their knowledge and experience in occupational safety and health.

The 12-member NACOSH has two members representing management, two members representing labor, two members representing the occupational health professions, two members representing the occupational safety professions and four members representing the public. Two of the health representatives and two of the public members are designated by the Secretary of Health and Human Services, although actual appointment of these members, as well as all other members, is by the Secretary of Labor. The members serve two-year terms.

NACOSH Statement on OSHA’s New Chemical Hazard Information Tools

NACOSH commends and applauds OSHA and the OSHA staff for the development of the new chemical hazard information tools – the annotated table of chemical exposure limits and the toolkit on transitioning to safer chemicals – that are available on the agency’s website.

These new tools bring together in one place a wide range of information on chemical hazards that will be of great use to employers, workers, safety and health professionals and others in their efforts to reduce workplace chemical exposures. This information is particularly important since many exiting OSHA permissible exposure limits (PELs) are outdated and do not adequately protect workers from adverse health effects.

NACOSH encourages OSHA to disseminate these new tools as widely as possible to employers, workers, trade associations, unions, safety and health organizations and others so they may be widely utilized. The committee stands ready to assist OSHA in this effort.
