OSHA's standardized SDS format uses 16 numbered sections. The sequence helps workplace users locate information consistently, but the SDS should still be treated as a complete product-specific document rather than as isolated sections.
Sections 1–4: identity and immediate hazards
Section 1 identifies the product and supplier. Section 2 summarizes hazard identification. Section 3 covers composition or ingredient information. Section 4 contains first-aid information.
Sections 5–8: incident response and exposure control
Section 5 addresses firefighting information, Section 6 accidental-release information, Section 7 handling and storage, and Section 8 exposure controls and personal protection.
Sections 9–11: technical hazard information
Section 9 covers physical and chemical properties, Section 10 stability and reactivity, and Section 11 toxicological information.
Sections 12–15: environmental and regulatory topics
These sections cover ecological information, disposal considerations, transport information and regulatory information. They appear in the standardized format, although OSHA does not enforce their content.
Section 16: other information
Section 16 includes other information such as the date of preparation or last revision. This can help users confirm whether they are looking at the current document supplied for the product.
Use the SDS as a reference, not a substitute for training
Workers should follow their employer's hazard-communication program, training and approved procedures. Reading section headings alone does not replace product-specific instruction.
