Placard: Toxic. ERG Guide 151. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.

🚒☣️
⚠️ This page is a quick-reference aid. For real incidents: stage upwind, isolate, deny entry, request Hazmat early, and consult the current ERG + SOP/SOG.

UN 1616 is Lead acetate, a toxic hazardous material assigned to ERG Guide 151. Responders should verify the exact product with shipping papers, package markings and SDS before close action.

Hazard overview: UN 1616 presents toxic exposure hazards by inhalation, ingestion or skin contact. Fire, decomposition or runoff may produce toxic contamination and require air monitoring, isolation and decontamination.

Response guidance: For a UN 1616 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 or vapor exposure, control runoff and choose entry or cleanup actions based on monitoring, SDS and local SOP.

Firefighter training notes: Training for UN 1616 should emphasize toxic exposure routes, air monitoring, PPE selection, decontamination and preventing contaminated runoff. Use ERG 151, SDS and local SOP.

Regulatory context: Lead acetate 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: Lead acetate should be stored in tightly closed compatible containers in a secure toxic-material area according to SDS and local hazardous materials procedures.

Fireground Response Guidance — UN 1616

Extinguishing Media

Use extinguishing agents appropriate for the surrounding fire and SDS. Water spray may cool containers or reduce dust only when runoff can be controlled as toxic contamination.

PPE Requirements

⚠️ Level B minimum; full-face respirator with HEPA filters; chemical-resistant gloves and suit required to prevent skin contact

Use positive-pressure SCBA for dust, vapor, mist, fire or confined-space exposure. Chemical-resistant gloves, eye/face protection and protective clothing should be selected from SDS because the exact formulation controls exposure risk.

Isolation & Evacuation

ERG 151: isolate spill area at least 25m in all directions; if large spill isolate 50m and evacuate downwind
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 151).

First Actions for a UN 1616 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 or mist and avoid all skin or eye contact.
  • Do not touch or walk through spilled material unless properly trained and wearing appropriate protective equipment.
  • 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, fire involvement or unknown concentration is present.
  • Use ERG Guide 151, shipping papers, SDS, air monitoring and incident command for protective actions.
