General Description
A slurry of white crystals. When dry, a high explosive that easily ignited and quick to burn vigorously. Wetting reduces sensitivity to shock and heat. Generates toxic oxides of nitrogen when burned.
Hazards
Reactivity Alerts
- Highly Flammable
- Explosive
Air & Water Reactions
Highly flammable. Soluble in water.
Fire Hazard
Excerpt from 113
[Flammable Materials (Wet / Desensitized Explosive)]:
Flammable/combustible material. May be ignited by heat, sparks or flames. DRIED OUT material may explode if exposed to heat, flame, friction or shock; treat as an explosive, refer to 112
. Keep material wet with water or treat as an explosive, refer to 112
. Runoff to sewer may create fire or explosion hazard. (ERG, 2020)
Health Hazard
Excerpt from 113
[Flammable Materials (Wet / Desensitized Explosive)]:
Some are toxic and may be fatal if inhaled, ingested or absorbed through skin. Specifically, Dinitrophenol, wetted (UN1320); Dinitrophenolates, wetted (UN1321), Sodium dinitro-o-cresolate, wetted (UN1348); and Barium azide, wetted (UN1571) are known to be toxic. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2020)
Reactivity Profile
BARIUM AZIDE, WETTED WITH NOT LESS THAN 50% WATER is a suspension or slurry of of an unstable solid in sufficient water to allow safe shipping and handling. May explode if allowed to dry out and then heated or shocked. Incompatible with strong oxidizing agents, strong reducing agents.
Belongs to the Following Reactive Group(s)
- Azo, Diazo, Azido, Hydrazine, and Azide Compounds
- Water and Aqueous Solutions
Potentially Incompatible Absorbents

Response Recommendations
Isolation and Evacuation
Excerpt from 113
[Flammable Materials (Wet / Desensitized Explosive)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area immediately for at least 100 meters (330 feet) in all directions.
LARGE SPILL: Consider initial evacuation for 500 meters (1/3 mile) in all directions.
FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from 113
[Flammable Materials (Wet / Desensitized Explosive)]:
CARGO FIRE: DO NOT fight fire when fire reaches cargo! Cargo may EXPLODE! Stop all traffic and clear the area for at least 1600 meters (1 mile) in all directions and let burn. Do not move cargo or vehicle if cargo has been exposed to heat.
TIRE OR VEHICLE FIRE: Use plenty of water - FLOOD it! If water is not available, use CO2, dry chemical or dirt. If possible, and WITHOUT RISK, use unmanned master stream devices or monitor nozzles from maximum distance to prevent fire from spreading to cargo area. Pay special attention to tire fires as re-ignition may occur. Stand by, at a safe distance, with extinguisher ready for possible re-ignition. (ERG, 2020)
Non-Fire Response
Excerpt from 113
[Flammable Materials (Wet / Desensitized Explosive)]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material.
SMALL SPILL: Flush area with large amounts of water.
LARGE SPILL: Wet down with water and dike for later disposal. KEEP "WETTED" PRODUCT WET BY SLOWLY ADDING FLOODING QUANTITIES OF WATER. (ERG, 2020)
Protective Clothing
Excerpt from ERG Guide 113 [Flammable Materials (Wet / Desensitized Explosive)]:
Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
Excerpt from 113
[Flammable Materials (Wet / Desensitized Explosive)]:
Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air if it can be done safely. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. (ERG, 2020)
