# SDS Lookup

> Look up safety data sheet (SDS) information for thousands of chemicals: GHS hazard statements, pictograms, exposure limits, first aid, PPE, storage and transport data — plus a free AI tool that reads and explains any SDS you upload.

SDS Lookup summarizes public safety data for 130 chemical substances in the 16-section SDS format (identification, GHS hazards, first aid, fire-fighting, spills, storage, exposure limits/PPE, properties, reactivity, toxicology, ecology, disposal, transport, regulatory). Data comes from PubChem and the sources it aggregates (EU CLP Annex VI harmonised classifications, ECHA C&L Inventory notifications, NIOSH, OSHA, NOAA CAMEO Chemicals, HSDB); every fact is attributed on the page. GHS statement wording is GHS Rev. 10. Pages describe pure substances and do not replace a supplier's SDS.

## Key pages
