Look up chemical safety data, GHS classification, DOT/IMDG transport information, and NFPA hazard ratings. Search by chemical name, CAS number, or UN/NA number.
A Safety Data Sheet (SDS) is a standardized document that provides information about chemical hazards, safe handling, storage, emergency procedures, and transport classification. SDSs follow the GHS (Globally Harmonized System) format with 16 mandatory sections covering identification, hazards, composition, first aid, fire fighting, accidental release, handling, exposure controls, physical properties, stability, toxicology, ecology, disposal, transport, regulatory, and other information.
GHS pictograms are standardized hazard symbols: the flame (flammable), exclamation mark (irritant/harmful), skull and crossbones (acute toxicity), corrosion (corrosive), exploding bomb (explosive), flame over circle (oxidizer), gas cylinder (compressed gas), health hazard (serious health effects), and environment (aquatic toxicity). Each pictogram indicates a specific category of hazard.
The NFPA 704 diamond is a color-coded hazard rating system used by emergency responders. Blue = health hazard, Red = flammability, Yellow = instability/reactivity, White = special hazards. Each color section is rated 0 (minimal hazard) to 4 (severe hazard).
