# NIH API: Get chemical safety > Looks up a chemical on PubChem by name or CAS number and returns its GHS hazard labels, route-specific first aid, flash point and workplace exposure limits. Unofficial. Not affiliated with or endorsed by NIH. - Page: https://fous.com/methods/pubchem.ncbi.nlm.nih.gov/get-chemical-safety - Method: `pubchem.ncbi.nlm.nih.gov/get_chemical_safety`, version 1 - Website: pubchem.ncbi.nlm.nih.gov - Returns: name, signal word, hazard statements and codes, pictograms, first aid, flash point, exposure limits, PubChem link - Effect: read (it gets data and changes nothing) - Sign-in: none needed - Cost: 1 credit per completed run (1¢ with pay as you go); failed runs are free - Verified: Nov 2, 2026 ## Inputs | Field | Type | Required | In the run below | Description | |---|---|---|---|---| | `chemical` | string | yes | `"acetone"` | Common chemical name or CAS number, for example acetone, bleach, or 67-64-1. | ## Output From a run on Oct 23, 2026. Its input: ```json { "chemical": "acetone" } ``` Its output: ```json { "name": "Acetone", "first_aid": { "eyes": "Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.", "skin": "Remove contaminated clothes. Rinse skin with plenty of water or shower.", "swallowing": "Rinse mouth. Do NOT induce vomiting.

To connect one, give it `set up https://fous.com/SKILL.md`. ## Ask your agent - What are the GHS hazard labels and first aid steps for acetone? - I need the flash point and exposure limits for CAS 67-64-1. - Is household bleach dangerous to inhale? Show me the hazard statements and pictograms. - Look up safety data for sodium hydroxide on PubChem, including signal word and skin contact first aid. - What's the workplace exposure limit and flash point for toluene (CAS 108-88-3) on nih.gov? ## Input schema ```json { "type": "object", "required": [ "chemical" ], "properties": { "chemical": { "type": "string", "description": "Common chemical name or CAS number, for example acetone, bleach, or 67-64-1." } } } ``` ## Output schema ```json { "type": "object", "required": [ "name", "signal_word", "hazard_statements", "hazard_pictograms", "first_aid", "flash_point", "workplace_exposure_limits", "safety_section_link", "ghs_hazard_codes", "pubchem_compound_id" ], "properties": { "name": { "type": "string", "description": "PubChem name of the matched compound." }, "first_aid": { "type": "object", "required": [ "eyes", "skin", "breathing_in", "swallowing" ], "properties": { "eyes": { "type": [ "string", "null" ] }, "skin": { "type": [ "string", "null" ] }, "swallowing": { "type": [ "string", "null" ] }, "breathing_in": { "type": [ "string", "null" ] } }, "additionalProperties": false }, "flash_point": { "type": [ "string", "null" ], "description": "Reported flash point with units." }, "signal_word": { "type": [ "string", "null" ], "description": "GHS signal word, Danger or Warning, when reported." }, "ghs_hazard_codes": { "type": [ "array", "null" ], "items": { "type": "string" }, "description": "GHS H-codes corresponding to the hazard statements.", "x-fous-developer": true }, "hazard_pictograms": { "type": [ "array", "null" ], "items": { "type": "object", "required": [ "name", "image_link" ], "properties": { "name": { "type": "string" }, "image_link": { "type": "string" } }, "additionalProperties": false }, "description": "GHS pictogram names and images." }, "hazard_statements": { "type": [ "array", "null" ], "items": { "type": "string" }, "description": "GHS hazards in plain words." }, "pubchem_compound_id": { "type": "integer", "description": "PubChem compound ID.", "x-fous-developer": true }, "safety_section_link": { "type": "string", "description": "PubChem Safety and Hazards section." }, "workplace_exposure_limits": { "type": [ "string", "null" ], "description": "Reported OSHA or other workplace exposure limits with units." } }, "additionalProperties": false } ``` ## See more - [NIH API: Get chemical facts by name or CAS number](https://fous.com/methods/pubchem.ncbi.nlm.nih.gov/get-chemical.md): Looks up a chemical on PubChem by common name or CAS number and returns its formula, molecular weight, names, description, SMILES, InChIKey and 2D structure image link. - [NIH API: Search PubMed articles](https://fous.com/methods/pubmed.ncbi.nlm.nih.gov/search-articles.md): Finds PubMed medical and life-science articles by topic, with publication details and free full-text links when PubMed confirms them. - [NIH API: Search grants](https://fous.com/methods/reporter.nih.gov/search-grants.md): Finds NIH research grants by topic, organisation, or researcher name.
