UN 1467 Quick Details
UN 1467
Product name: Guanidine nitrate
DOT Class: 5
Placard type: Oxidizer
ERG Guide: 143 (check current ERG)
Initial isolation: ERG 143: Isolate spill 25-50m all directions. If fire involves bulk quantities, evacuate 800m radius and fight fire from maximum distance. Treat as potential explosion hazard.
Common Hazards of UN 1467
- May explode from friction, heat or contamination.
- These substances will accelerate burning when involved in a fire.
- May ignite combustibles (wood, paper, oil, clothing, etc.).
- Some will react explosively with hydrocarbons (fuels).
- Containers may explode when heated.
- Runoff may create fire or explosion hazard.
- TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe
- Fire may produce irritating and/or toxic gases.
Chemical Identity & Physical Properties
| Also known as | Guanidinium nitrateGuanidine mononitrateNitroguanidine precursor saltGN explosive |
| CAS Number | 506-93-4 |
| Appearance | 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. |
| Flash Point | Not applicable (oxidizing solid) |
| Boiling Point | Not applicable (decomposes above 215C/419F) |
| Vapor Density | Not applicable (solid) |
| Water Reactivity | Soluble in water; no violent reaction but dissolution generates heat. Keep contamination-free. |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Fireground Response Guidance — UN 1467
Extinguishing Media
Dry chemical, CO2, or dry sand preferred. Water spray may be used from distance to cool containers but avoid direct application to bulk material.
PPE Requirements
⚠️ Level B minimum with SCBA and chemical-resistant suit. Avoid all ignition sources. Handle as explosion-sensitive material; static precautions required.
Isolation & Evacuation
ERG 143: Isolate spill 25-50m all directions. If fire involves bulk quantities, evacuate 800m radius and fight fire from maximum distance. Treat as potential explosion hazard.
Always confirm protective actions with the current edition of the Emergency Response Guidebook (ERG Guide 143).
First Actions for a UN 1467 Incident
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- 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
- For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
- For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind
