OSHA requires an SDS for any materials that:
- Meet the OSHA definition of hazardous, and
- Are "known to be present in the workplace in such a manner that employees may be exposed under normal conditions of use or in a foreseeable emergency."
Definition of Hazardous Materials
Health Hazard means a chemical for which there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees. The term "health hazard" includes chemicals which are carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers, hepatotoxins, nephrotoxins, neurotoxins, agents that act on the hematopoietuc system and agents which damage the lungs, skin, eyes, or mucous membranes.
Physical Hazard means a chemical for which there is significantly valid evidence that is a combustible liquid, a compressed gas, explosive, flammable, or organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive.
In Canada, a product which falls withing any of the hazard criteria set out in Part IV of the Controlled Product Regulations (CPR) is a WHMIS "controlled product" and, unless except under Section 12 of the Hazardous Products Act (HPA), is subject to the SDS requirements of the HPA.
Hazard statements are indicated on the chemical label, as well as on the SDS.
