Occupational Health Guidelines for Chemical Hazards						Print
																Related Pages
										January 1981
DHHS (NIOSH) Publication Number 81-123
Occupational Health Guidelines for Chemical Hazards summarizes information on permissible exposure limits, chemical and physical properties, and health hazards. It provides recommendations for medical surveillance, respiratory protection, and personal protection and sanitation practices for specific chemicals that have Federal occupational safety and health regulations. These recommendations reflect good industrial hygiene and medical surveillance practices, and their implementation will assist development and maintenance of an effective occupational health program.
