Formerly known as Material Safety Data Sheets (MSDS), an SDS must be provided by the chemical manufacturer, distributor, or importer to communicate the hazards of the chemical product. OSHA's Hazard Communication Standard (29 CFR 1910.1200) requires new SDSs to be in a uniform format. The section numbers, headings, and associated information under the headings are:

Section 1, Identification: product identifier (chemical name, product name, etc.); manufacturer or distributor name, address, phone number;  emergency phone number; recommended use' restrictions on use.

Section 2, Hazard(s) Identification: hazard classification; required label elements (signal word, pictogram(s), hazard statement(s), precautionary statement(s)).

Section 3, Composition/ Information on ingredients: chemical ingredients that contribute to the hazard classification; trade secret claims; chemical name; common name and synonyms; CAS number.

Section 4, First Aid measures: symptoms/ effects, acute, delayed; required treatment.

Section 5, Fire-fighting measures: suitable extinguishing techniques, equipment; chemical hazards from fire.

Section 6, Accidental release measures: emergency procedures; protective equipment; proper methods of containment and cleanup.

Section 7, Handling and Storage: advice on specific storage requirements; precautions for safe handling and storage, including incompatibilities.

Section 8, Exposure controls/ personal protection:  OHSA's Permissible Exposure Limits (PELs); ACGIH Threshold Limit Values (TLVs); and any other exposure limit used or recommended by the party preparing the SDS; appropriate engineering controls; personal protective equipment (PPE).

Section 9, Physical and chemical properties: chemical characteristics,  including: appearance, form, color, odor, odor threshold, melting point, boiling point, pH, flash point, density, solubility, etc.

Section 10, Stability and reactivity: chemical stability; possibility of hazardous reactions; incompatible materials; conditions to be avoided.

Section 11, Toxicological information: routes of exposure; related symptoms; acute and chronic effects; numerical measures of toxicity.

Section 12, Ecological information (non-mandatory): toxicity tests on aquatic or terrestrial organisms; potential for chemical persistence and degradation in the environment; bioaccumulation potential; other adverse effects.

Section 13, Disposal considerations (non-mandatory): guidance on proper disposal practices.

Section 14, Transport information (non-mandatory): shipping and transportation information; UN number; UN proper shipping name; DOT hazards class(es).

Section 15, Regulatory information (non-mandatory): safety, health, and environmental regulations specific for the product not indicated anywhere else on the SDS.

Section 16, Other information: date of preparation or last revision.
