UN 1469 — Lead nitrate
Placard: Oxidizer. ERG Guide 141. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1469 is Lead nitrate, a Class 5 lead oxidizer assigned to ERG Guide 141. It can intensify fire and create toxic lead-contaminated dust, smoke or runoff.
Hazard overview: UN 1469 presents oxidizer, heat/contamination and lead toxicity hazards. Avoid dust inhalation, keep away from fuels and organics, and control runoff as contaminated material.
Response guidance: For a UN 1469 incident, responders should verify the product with shipping papers, package markings, SDS and ERG Guide 141. Establish incident command, isolate the area, stay upwind, keep fuels and organics away, avoid contaminated absorbents and choose extinguishing or spill-control actions based on ERG, SDS and local SOP.
Firefighter training notes: Training for UN 1469 should emphasize oxidizer fire behavior plus toxic metal contamination control, dust avoidance, PPE selection, decontamination and runoff containment. Use ERG 141, SDS and local SOP.
Regulatory context: Lead nitrate 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, 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 nitrate should be stored in compatible oxidizer storage away from fuels, organics, reducing agents, heat and contamination. Keep containers closed and dry, and manage dust/runoff controls because toxic metal contamination may create additional regulatory and cleanup concerns.
UN 1469 Quick Details
Common Hazards of UN 1469
- OXIDIZER: may intensify fire and accelerate burning of combustible materials.
- May ignite combustibles such as wood, paper, oil, clothing, packaging or contaminated absorbents.
- Lead oxidizer salts can react dangerously with fuels, organics or reducing agents.
- Containers may rupture or explode when heated.
- Fire may produce irritating and/or toxic gases.
- Runoff may spread oxidizing material and create fire, explosion or environmental hazards.
- Dust, solution or decomposition products may irritate or injure eyes, skin or respiratory tissue.
- Lead-containing dust, smoke and runoff are toxic and should be controlled as contaminated material.

PPE Requirements
Use positive-pressure SCBA for fire, dust, decomposition or confined-space exposure. Chemical-resistant gloves, eye/face protection and protective clothing should be selected from SDS; avoid lead-contaminated dust, smoke and runoff.
Isolation & Evacuation
First Actions for a UN 1469 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.
- Keep combustibles, fuels, organics, reducing agents and contaminated materials away from the spill.
- Do not touch or walk through spilled material unless properly trained and wearing appropriate protective equipment.
- Avoid creating dust clouds and prevent runoff from contacting combustibles, drains or incompatible materials when possible.
- Ventilate closed spaces before entering, but only if properly trained, equipped and authorized by incident command.
- Isolate the spill or fire area and expand the perimeter if large quantities, contamination, heating or container involvement are present.
- Use ERG Guide 141, shipping papers, SDS and local SOP for protective actions and entry decisions.
