Which of the following is NOT considered a hazardous material according to Cal/OSHA's Hazard Communication Standard (HCS)?
- AA chemical that is a health hazard, such as a carcinogen.
- BA substance that poses no physical or health hazards but is listed on the SDS.
- CA chemical that is a physical hazard, such as an explosive.
- DA substance that is classified as hazardous by the manufacturer.
Show answer & explanationAnswer & explanation
Correct answer: B. A substance that poses no physical or health hazards but is listed on the SDS.
The Cal/OSHA Hazard Communication Standard defines hazardous materials based on their physical or health hazards. A substance that poses no such hazards, even if listed on an SDS for other reasons, would not be considered a hazardous material under HCS.
Why the other options are wrong
- A. Health hazards are explicitly covered by HCS.
- C. Physical hazards are explicitly covered by HCS.
- D. Manufacturer classification as hazardous is a primary trigger for HCS coverage.
Cal/OSHA Hazardous Material Definition
Under Cal/OSHA HCS, a hazardous material is any chemical that is a physical hazard or a health hazard.
- Physical hazards include flammables, explosives, oxidizers.
- Health hazards include carcinogens, irritants, toxins.
- The presence of an SDS alone does not define a hazardous material if no hazard exists.
Memory trick: Hazardous materials are 'Physical-Health' threats.
