Above a given \"Control Temperature\"\nthey may decompose or polymerize violently and catch fire.\n•\nMay be ignited by heat, sparks or flames.\n•\nThose substances designated with a (P) may polymerize explosively when heated or involved in a fire.\n•\nSome may decompose explosively when heated or involved in a fire.\n•\nMay burn violently. Decomposition or polymerization may be self-accelerating and produce large\namounts of gases.\n•\nVapors or dust may form explosive mixtures with air.\n•\n•\n•\nHEALTH\nInhalation or contact with vapors, substance or decomposition products may cause severe injury or\ndeath.\nMay produce irritating, toxic and/or corrosive gases.\nRunoff from fire control or dilution water may cause environmental contamination.\nPUBLIC SAFETY\nCALL 911. Then call emergency response telephone number on shipping paper. If shipping paper\nnot available or no answer, refer to appropriate telephone number listed on the inside back cover.\nKeep unauthorized personnel away.\nStay upwind, uphill and/or upstream.\n•\n•\n•\nPROTECTIVE CLOTHING\n•\nWear positive pressure self-contained breathing apparatus (SCBA).\n•\nWear chemical protective clothing that is specifically recommended by the manufacturer when there is\nNO RISK OF FIRE.\n•\nStructural firefighters' protective clothing provides thermal protection but only limited chemical protection.\nEVACUATION\nImmediate precautionary measure\n•\nIsolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters\n(75 feet) for solids.\nLarge Spill\n•\n•\nConsider initial evacuation for at least 250 meters (800 feet) in all directions.\nFire\nIf tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all\ndirections; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.\nPage 230\nERG 2024\n\nSubstances (Self-Reactive/\nTemperature Controlled)\nGUIDE\n150\nEMERGENCY RESPONSE\nFIRE\n•\nThe temperature of the substance must be maintained at or below the “Control Temperature” at\nall times.\nSmall Fire\n•\n•\nDry chemical, CO2, water spray or regular foam.\nLarge Fire\nFlood fire area with water from a distance.\n•\n•\nIf it can be done safely, move undamaged containers away from the area around the fire.\nFire Involving Tanks, Rail Tank Cars or Highway Tanks\nBEWARE OF POSSIBLE CONTAINER EXPLOSION.\n•\nFight fire from maximum distance or use unmanned master stream devices or monitor nozzles.\n•\nCool containers with flooding quantities of water until well after fire is out.\n•\nWithdraw immediately in case of rising sound from venting safety devices or discoloration of tank.\n•\nALWAYS stay away from tanks in direct contact with flames.\nSPILL OR LEAK\n•\nDO NOT allow the substance to warm up. Use a coolant agent such as dry ice or ice (wear thermal\nprotective gloves). If this is not possible or none can be obtained, evacuate the area immediately.\n•\nELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.\n•\nDo not touch or walk through spilled material.\n•\nStop leak if you can do it without risk.\nSmall Spill\n•\nPick up with inert, damp, non-combustible material using clean, non-sparking tools and place into loosely\ncovered plastic containers for later disposal.\n•\nPrevent entry into waterways, sewers, basements or confined areas.\n•\nDO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.\nFIRST AID\nRefer to the “General First Aid” section.\nIn Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product.\nPlease consult the shipping paper and/or the \"ERAP\" section.\nERG 2024\nPage 231","truncated":false,"body_characters":3985}
