GHS Label & SDS Decoder
A free reference for reading chemical labels and safety data sheets under OSHA's Hazard Communication Standard (29 CFR 1910.1200). It covers the nine GHS pictograms, the two signal words, the 16 SDS sections, and a selection of common H-codes (hazard statements) and P-codes (precautionary statements).
There is no calculation. Eight of the nine pictograms are required under the Hazard Communication Standard. The Environment pictogram is part of GHS but is not required by OSHA. A label carries only one signal word: Danger for the more severe hazard categories and Warning for the less severe ones. Every SDS follows the same 16-section order. OSHA enforces sections 1 to 11 and 16, and does not enforce sections 12 to 15. The code lookup holds a selection of common statements and is not the full GHS list, so always defer to the product's own SDS.
How to use it
- Tap a pictogram to see what it warns about and the hazard classes it covers.
- Read what the Danger and Warning signal words mean.
- Walk the 16 SDS sections to find where a piece of information lives.
- Search an H-code, a P-code or a keyword in the lookup.
