Msds Chain

Check pairwise compatibility between a list of chemicals. Returns compatibility status (compatible / caution / incompatible) for each pair, along with specific hazard reasons and storage recommendations. Use this before an experiment to verify it is safe to use the listed chem...

Get hazard and risk warnings for one or more chemicals. Returns GHS hazard classification, signal words (Danger/Warning), H-codes, flash point, toxicity, and recommended PPE. Use this to understand the specific dangers of each chemical before handling or storing them. Args: ch...

Check multi-region regulatory compliance status for chemicals. Checks against: EU (SVHC/REACH/CLP/CMR), US (OSHA PEL/TSCA), CN, JP, KR, CA, AU, TW regulations. Use this when preparing export documentation, compliance audits, or when working with chemicals that may be restricte...

Ask any chemical safety question in natural language. Handles: storage conditions, spill/exposure emergency procedures, first-aid measures, PPE requirements, disposal guidance, MSDS lookups, GHS label interpretation, and general lab safety questions. Use this as the catch-all...

Get PPE (Personal Protective Equipment) recommendations for chemicals. Returns specific glove types, eye protection, respiratory protection, and body protection requirements based on MSDS Section 8 data and GHS hazard codes. Args: chemicals: List of chemical names or CAS numbe...

Get storage and isolation guidance for chemicals. Returns storage class (flammable/oxidizer/corrosive/toxic/general), recommended cabinet type and color code, temperature requirements, incompatible materials for isolation, and specific storage instructions derived from SDS Sec...

Get emergency response guidance for a chemical incident. Returns immediate actions, SDS-specific instructions from Section 4/5/6, and H-code-based guidance for three scenario types. Args: chemical: Chemical name or CAS number, e.g. "hydrochloric acid" scenario: Type of emergen...

Get occupational exposure limits (OEL/TLV/PEL/MAC) for chemicals. Returns TWA, STEL, and Ceiling values from multiple standards: - OSHA PEL (US) - ACGIH TLV (International) - EU SCOEL IOELV - Japan 産衛研 - China GBZ Args: chemicals: List of chemical names or CAS numbers region:...

Get UN transport classification for chemicals (dangerous goods shipping). Returns UN number, proper shipping name, hazard class, packing group, and transport mode details (ADR road, IATA air, IMDG sea). Args: chemicals: List of chemical names or CAS numbers

Run a full MSDS safety audit for a list of chemicals and return a session id. Creates a persistent audit session on MSDS Chain, runs pairwise compatibility and risk analysis across all chemicals, and returns a session_id that can later be passed to `get_audit_report` to fetch...

Get a short-lived signed URL to download the audit report PDF. Use after `create_audit_session` to retrieve an archivable PDF report containing the chemicals, compatibility matrix, risk warnings, and session metadata. Args: session_id: The session id returned by `create_audit_...

Search the MSDS Chain database for a specific chemical. Returns structured information: CAS number, chemical name, NFPA ratings (flammability, health, reactivity), GHS classification, and whether full MSDS data is available. Use this to verify a chemical is in the database bef...

Retrieve a specific SDS (Safety Data Sheet) section for a chemical. The 16 standard GHS-SDS sections are: 1. Identification 2. Hazard(s) identification 3. Composition / ingredients 4. First-aid measures 5. Fire-fighting measures 6. Accidental release measures 7. Handling and s...

Suggest safer alternatives for a chemical, considering its intended use. Returns 2-4 alternative chemicals with: name, CAS number, why it's safer (lower toxicity, higher flash point, non-CMR, etc.), any trade-offs (cost, availability, performance), and relevant regulatory cont...

Extract and validate chemical names from a protocol or experiment description. Parses free-text or code (e.g., Opentrons Python protocol, lab notebook entry, SOP paragraph) to identify all mentioned chemicals, then checks each against the MSDS Chain database. Returns a structu...

Determine the safe order for mixing/adding two chemicals. Returns the recommended addition sequence, the dangerous sequence to avoid, reasoning (exothermic potential, gas evolution, splashing risk), and any required precautions (cooling, dilution rate, inert atmosphere). Class...

Get waste classification and disposal guidance for chemicals. Returns waste category (halogenated/non-halogenated/acidic/alkaline/ heavy metal/oxidizing/reactive), disposal method, container requirements, and incompatible waste streams that must NOT be mixed. Based on SDS Sect...

Run a comprehensive safety check on a list of chemicals in one call. Returns a combined report with: - Pairwise compatibility matrix (compatible/caution/incompatible) - PPE requirements (merged across all chemicals) - Storage grouping recommendations (which chemicals can share...
