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.
