UN 1467 — Guanidine nitrate
Placard: Oxidizer. ERG Guide 143. Training/quick-reference only — use current ERG + SOP/SOG for incident-specific actions.
UN 1467 is Guanidine nitrate, a Class 5 nitrate oxidizer assigned to ERG Guide 143. It may be more sensitive to heat, friction, shock or contamination than ordinary oxidizer salts.
Hazard overview: UN 1467 presents oxidizer, heat/friction and contamination hazards. Treat bulk or contaminated material as potentially explosion-sensitive and avoid unnecessary impact, sparks or mixing with incompatible materials.
Response guidance: For a UN 1467 incident, responders should verify the product with shipping papers, package markings, SDS and ERG Guide 143. 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 1467 should emphasize oxidizer fire behavior, separation from fuels and organics, contamination control, dust avoidance, container-heating hazards and correct extinguishing decisions. Common errors include treating oxidizers like ordinary combustibles and using contaminated absorbents. Use ERG 143, SDS and local SOP.
Regulatory context: Guanidine 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: Guanidine nitrate should be stored in compatible oxidizer storage away from fuels, organic materials, reducing agents, acids where incompatible, heat, ignition sources and contamination. Keep containers closed, dry, clearly labeled and separated from combustible packaging or spilled residues.
UN 1467 Quick Details
Common Hazards of UN 1467
- OXIDIZER: may intensify fire and accelerate burning of combustible materials.
- May explode from friction, heat, shock or contamination.
- Nitrate oxidizer material may react dangerously with fuels, organic material, reducing agents or contaminated absorbents.
- 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.
Chemical Identity & Physical Properties
White to colorless crystalline solid or powder. Odorless or slight ammonia-like odor. Stable at room temperature but becomes increasingly sensitive with contamination or heating.

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 and incident command.
Isolation & Evacuation
First Actions for a UN 1467 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 143, shipping papers, SDS and local SOP for protective actions and entry decisions.
