A Safety Data Sheet is the standardized, 16-section document required by 29 CFR 1910.1200(g) for every hazardous chemical. SDS packets outline ingredients, hazard classifications, PPE requirements, first-aid steps, and disposal instructions under the GHS system. SMB teams should maintain digital and paper access, track the revision date, and tie the sheet back to their inventory list so auditors see nothing missing. We also reference SDS numbers in our training LMS so employees can prove they reviewed the correct document.
