UN 1692 — Strychnine salts
Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1692 is Strychnine salts, a highly toxic alkaloid salt assigned to ERG Guide 151. Dust, ingestion, skin contact and contaminated runoff should be controlled as serious toxic hazards.
Hazard overview: UN 1692 presents severe systemic poison, dust and contamination hazards. Fire may produce toxic gases, and runoff or contaminated equipment can create secondary exposure.
Response guidance: For a UN 1692 incident, responders should verify the product with shipping papers, package markings, SDS and ERG Guide 151. Establish incident command, isolate the area, stay upwind, prevent dust, vapor or aerosol exposure, control runoff and choose entry or cleanup actions based on monitoring, SDS and local SOP.
Firefighter training notes: Training for UN 1692 should emphasize toxic exposure routes, air monitoring, PPE selection, decontamination and preventing contaminated runoff. Use ERG 151, SDS and local SOP.
Regulatory context: Strychnine salts is regulated as a hazardous material for transportation and emergency response purposes. Transportation, workplace exposure, spill reporting, waste handling, storage and environmental requirements may vary by formulation, concentration, quantity and jurisdiction. Verify current requirements through shipping papers, SDS, facility documents and applicable DOT, OSHA, EPA, NFPA, state or local authority guidance.
Storage & handling: Strychnine salts should be stored in tightly closed compatible containers in a secure toxic-material area according to SDS and local hazardous materials procedures.

PPE Requirements
Use positive-pressure SCBA for dust, mist, fire or confined-space exposure. Chemical-resistant gloves, eye/face protection and protective clothing should be selected from SDS; avoid any skin contact and prevent secondary contamination.
Isolation & Evacuation
First Actions for a UN 1692 Incident
- CALL 911. Then call the emergency response telephone number on the shipping paper, if available.
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Avoid breathing vapors, fumes, dust, mist, aerosol or smoke and avoid all skin or eye contact.
- Do not touch or walk through spilled material unless properly trained and wearing appropriate protective equipment.
- Avoid creating dust clouds or spreading contaminated liquid, powder, solution, runoff or debris.
- Ventilate closed spaces before entering, but only if properly trained, equipped, monitored and authorized by incident command.
- Isolate the spill or leak area and expand the perimeter if vapor, dust, aerosol, fire involvement or unknown concentration is present.
- Use ERG Guide 151, shipping papers, SDS, air monitoring and incident command for protective actions.
