UN 1469 — Lead nitrate

Placard: Oxidizer. ERG Guide 141. 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.

Lead nitrate is a highly reactive substance that can accelerate burning when involved in a fire. It is essential to handle this substance with caution and follow proper safety protocols.

Hazard overview: Lead nitrate may explode from heat or contamination, and can accelerate burning when involved in a fire.

Response guidance: In case of a fire, use water, fog, CO2, or dry chemical to extinguish the fire, and flood the area with water to prevent re-ignition.

Water, fog, CO2, dry chemical acceptable; flood with water in fire

PPE Requirements

⚠️ Level B minimum; SCBA required; chemical-resistant suit for large spills

Level B minimum personal protective equipment with SCBA and chemical-resistant suit is required for handling lead nitrate.

Isolation & Evacuation

ERG 141: isolate 25m minimum; if tank/rail car involved in fire, isolate 800m all directions
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 141).

First Actions for a UN 1469 Incident

  • Keep unauthorized personnel away.
  • Stay upwind, uphill and/or upstream.
  • Ventilate closed spaces before entering, but only if properly trained and equipped.
  • Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
  • Consider initial downwind evacuation for at least 100 meters (330 feet).
