What is a Safety Data Sheet?
A Safety Data Sheet (SDS) is a detailed document that provides comprehensive information about a hazardous chemical. Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), manufacturers must provide an SDS for every hazardous product, and employers must ensure workers can access these documents.
Understanding how to read an SDS quickly is critical — especially in emergencies when seconds matter. This guide walks you through all 16 sections and shows you where to find the most important information.
