May be colorless to colored, with characteristic odor depending on the organic compound. Represents a broad category of self-reactive organic liquids with lower hazard potential than types A-E. Water Reactivity: Generally no violent reaction with water, but may be water-immiscible; avoid contamination as some formulations may be sensitive to moisture Extinguishing: Dry chemical, CO2, water spray for cooling; foam may be used but compatibility depends on specific formulation PPE: Level B minimum; SCBA required in fire or decomposition scenarios; heat-protective clothing for fire situations; keep containers cool with water spray from distance Isolation: ERG 149: isolate spill or leak area immediately for at least 50m in all directions; if tank/rail car involved in fire, isolate 800m in all directions and consider initial evacuation for 800m — Key Hazards — • Self-decomposition, self-polymerization, or self-ignition may be triggered by heat, chemical • May be ignited by heat, sparks or flames. • Some may decompose explosively when heated or involved in a fire. — First Actions — • CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper • Keep unauthorized personnel away. • Stay upwind, uphill and/or upstream. • Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters SOURCE: allfirefighter.com/hazmat/un/3229 | Always use current ERG + SOP/SOGIC BRIEFING
