About SDS Lookup
SDS Lookup is a free reference site that helps workers, students and safety managers find and understand chemical safety information: safety data sheet summaries for individual chemicals, a full GHS reference, plain-English guides to SDSs and regulations, and an AI tool that explains an SDS you upload.
What we do
- Chemical pages. Each chemical page compiles public data under the same 16 headings as a real safety data sheet: identification, hazards, first aid, fire-fighting, exposure controls, properties, toxicology, transport and more. Every chemical-specific fact shows its source.
- GHS reference. The GHS pages explain pictograms, hazard classes and the full wording of hazard (H) and precautionary (P) statements from UN GHS Revision 10.
- Learning material. How to read an SDS, one page for each of the 16 SDS sections, practical guides and regulation overviews.
- AI SDS analyzer. The analyzer reads a safety data sheet you provide and explains it in plain language. See the privacy page for how uploads are handled.
Who it is for
Employees who want to know what is in the container in front of them, supervisors and safety officers who write procedures and training, students and teachers in chemistry and occupational health, and anyone who needs a quick, readable orientation before consulting the official documents.
Independence
SDS Lookup is an independent educational resource. We are not a chemical manufacturer, distributor or regulator, and we do not sell chemicals. We are not affiliated with OSHA, the EPA, ECHA, PubChem or any other source we cite. Our pages do not carry advertising.
How we approach accuracy
- Sources first. We compile data from public databases and show the source for chemical-specific facts. See data sources for the list and for how we choose between conflicting classifications.
- Standard wording. Hazard and precautionary statement text comes from the UN GHS data, not from retyping.
- Plain language, carefully. The guides and regulation overviews are written to be readable. Where we are not certain of a figure, date or citation, we describe it qualitatively or leave it out, and we point you to the official text.
- Empty is better than wrong. If a value is not available in the sources we compile, the page says so instead of guessing.
- Visible dates. Guides carry a last-modified date so that you can judge how current they are.
What we are not
We are not a substitute for the safety data sheet and label supplied by the manufacturer of your product, for legal advice, or for a workplace risk assessment. Please read our disclaimer. In an emergency, call your local emergency number or poison control center (in the US, 1-800-222-1222).
Found a mistake?
Accuracy matters more than anything else on a safety site. If something on a page conflicts with the supplier's SDS, the regulation text or a primary source, follow the primary source, and treat our page as the one that needs correcting. Each chemical page links to its main source so you can check it yourself.
