Retrieve GHS hazard classification data for a chemical via PubChem PUG-View

Steps

1. Identify the PubChem Compound ID (CID) for your chemical via PUG-REST, e.g. `GET https://pubchem.ncbi.nlm.nih.gov/rest/pug/compound/name/{name}/cids/JSON`.
2. Request the GHS Classification section of that compound's record with PUG-View: `GET https://pubchem.ncbi.nlm.nih.gov/rest/pug_view/data/compound/{cid}/JSON/?response_type=display&heading=GHS+Classification`.
3. Parse the returned JSON for hazard classification, signal word, pictograms, hazard statements, and precautionary statements — this data is compiled from source-specific hazard/SDS datasets rather than computed directly by PubChem.
4. For a fuller safety summary (first aid, handling, exposure controls), request the compound's Laboratory Chemical Safety Summary (LCSS) section using the same PUG-View pattern with a different `heading` value.
5. Remember PUG-View differs from PUG-REST: PUG-REST returns PubChem-computed property values, while PUG-View returns annotations aggregated from other data sources (including GHS/LCSS).
