ERG 2024 Guide 113, page 1GUIDE 113 Flammable Materials (Wet/Desensitized Explosive) POTENTIAL HAZARDS FIRE OR EXPLOSION • 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 (GUIDE 112). • Keep material wet with water or treat as an explosive (GUIDE 112). • Runoff to sewer may create fire or explosion hazard. • • • • HEALTH 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. PUBLIC SAFETY CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. Keep unauthorized personnel away. Stay upwind, uphill and/or upstream. Ventilate closed spaces before entering, but only if properly trained and equipped. • • • • PROTECTIVE CLOTHING • Wear positive pressure self-contained breathing apparatus (SCBA). • Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. EVACUATION 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.

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. SPILL OR LEAK • 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.
