The Definition of Safety Data Sheet (SDS)
A safety data sheet (SDS) is documentation that details the hazards, safe handling practices, and emergency measures for a chemical or hazardous substance.
A safety data sheet (SDS) is documentation that details the hazards, safe handling practices, and emergency measures for a chemical or hazardous substance.

A standardized document that provides information on a chemical's properties, health and physical hazards, handling and storage requirements, exposure controls, and emergency response measures. In the U.S., SDS format and content are governed by OSHA's Hazard Communication Standard (29 CFR 1910.1200), which aligns with the Globally Harmonized System (GHS).
A warehouse worker handling industrial cleaning solvent consults the product's SDS to confirm required PPE, learn the correct spill response, and identify first-aid steps in case of skin contact.
Chemical manufacturers, importers, and distributors must provide an SDS for each hazardous chemical they ship, and employers must keep these accessible to employees who may be exposed.
GHS format requires 16 standardized sections, including identification, hazard identification, composition, first-aid measures, handling and storage, exposure controls/PPE, and toxicological information.
No. An SDS is a reference document, not a substitute for hazard communication training, which employers must still provide so workers understand how to interpret and apply the information.
