General Description
A light yellow crystalline sludge or slurry. Burns but may require some effort to ignite. A high explosive when dry. Easily ignited and burns very vigorously when dry. Insoluble in water. Produces toxic oxides of nitrogen during combustion.

Insoluble in water.
Fire Hazard
Excerpt from ERG Guide 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 (ERG Guide 112). Keep material wet with water or treat as an explosive (ERG Guide 112). Runoff to sewer may create fire or explosion hazard. (ERG, 2024)
Health Hazard
Excerpt from ERG Guide 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, 2024)
Reactivity Profile
Aromatic nitro compounds, such as TRINITROBENZENE, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.

Response Recommendations

Isolation and Evacuation
Excerpt from ERG Guide 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 tank car or highway tank 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, 2024)
Firefighting
Excerpt from ERG Guide 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, 2024)
Non-Fire Response
Excerpt from ERG Guide 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, 2024)
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, 2024)
