What are our priorities?

The National Institute for Occupational Safety and Health (NIOSH) Authoritative Recommendations Program supports the scientific assessment, development, dissemination, and diffusion of NIOSH authoritative recommendations for assuring safe and healthy working conditions for all workers, particularly those who work with chemicals. Examples of authoritative recommendations include Recommended Exposure Limits (RELs), Immediately Dangerous to Life or Health (IDLH) values, Skin Notation (SK) Profiles, engineering controls, safe work practices, personal protective equipment, exposure monitoring, and medical monitoring, among others. The Program seeks to reduce and prevent occupational injuries, illnesses, and fatalities by developing and evaluating authoritative recommendations.
