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.\nVentilate closed spaces before entering, but only if properly trained and equipped.\n•\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.\nSpill\n•\n•\nFor highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.\nFor non-highlighted materials: increase the immediate precautionary measure distance, in the downwind\ndirection, as necessary.\nFire\n•\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 236\nERG 2024\n\nSubstances - Toxic and/or Corrosive\n(Combustible)\nGUIDE\n153\nEMERGENCY RESPONSE\nFIRE\nSmall Fire\n•\nDry chemical, CO2 or water spray.\nLarge Fire\n•\nDry chemical, CO2, alcohol-resistant foam or water spray.\n•\nIf it can be done safely, move undamaged containers away from the area around the fire.\n•\n•\nDike runoff from fire control for later disposal.\nFire Involving Tanks, Rail Tank Cars or Highway Tanks\nFight fire from maximum distance or use unmanned master stream devices or monitor nozzles.\n•\nDo not get water inside containers.\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•\nELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.\n•\nDo not touch damaged containers or spilled material unless wearing appropriate protective clothing.\n•\nStop leak if you can do it without risk.\n•\nPrevent entry into waterways, sewers, basements or confined areas.\n•\nAbsorb or cover with dry earth, sand or other non-combustible material and transfer to containers.\n•\nDO NOT GET WATER INSIDE CONTAINERS.\nFIRST AID\nRefer to the “General First Aid” section.\nSpecific First Aid:\n•\nFor corrosives, in case of contact, immediately flush skin or eyes with running water for at least 30\nminutes. Additional flushing may be required.\n•\nRemoval of solidified molten material from skin requires medical assistance.\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 237","truncated":false,"body_characters":4060}
