Subpart Z—Toxic and Hazardous Substances

Because each of these chemicals have unique properties, adverse affects, handling procedures, signs and symptoms of overexposure, and regulatory reqrriranents, the regulation specific to each chemical must be consulted and complied with. 

This subpart also covers hazard communication, bloodbome pathogens, ionizing radiation, placarding, and laboratories chemical safety.

Note that the number one OSHA citation listed in Table 9.12 for the oil and gas drilling industry is for noncompliance with 29 CFR 1910.1200, Hazard Communication. The 1984 Bhopal Incident, the ensuing chemical spill, and the resulting tragic deaths and injuries are well known however, the repercussions—the lessons learned—from this incident are not as well known. After Bhopal, a worldwide outcry arose How could such an incident occur Why wasn t something done to protect the inhabitants Weren t safety measures taken or in place to prevent such a disaster from occurring  

Needless to say. Congress was upset. Because of Bhopal and the Institute, West Virginia, incidents, OSHA mandated its Hazard Communication Program, 29 CFR 1910.1200, in 1984. Later, other programs, such as SARA (Superfund) Title III reporhng requirements for all chemical users, producers, suppliers, storage enhties, were mandated by USEPA. 

There is no all-inclusive list of chemicals covered by the Hazard Communication Standard however, the regulation refers to any chemical which is a physical or health hazard. Those specifically deemed hazardous include the following
