The Occupational Safety and Health Act of 1970 created the Occupational Safety and Health Administration (OSHA). OSHA, an agency of the U.S. Department of Labor, is charged with the enforcement of safety and health conditions of workers through the use of regulations published in the Code of Federal Regulations. OSHA regulations are published in Title 29 of the Code of Federal Regulations. Part 1910 is reserved for general industry standards while Part 1926 is designated for construction industry standards. This online toxic substances training course focuses on the chemical and toxic substances regulations found in Part 1926 for Construction Subparts D and Z; however, Part 1926 periodically references back to Part 1910 for General Industry.

The following OSHA regulations are applicable to chemical hazards and toxic substances in the construction industry:

• 29 CFR 1926.55 - Gases, vapors, fumes, dusts, and mists
• 29 CFR 1926.57 - Ventilation
