Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.\nLarge Fire\n•\nFlood fire area with water from a distance.\n•\nDo not move cargo or vehicle if cargo has been exposed to heat.\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\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•\nALWAYS stay away from tanks in direct contact with flames.\n•\nFor massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw\nfrom area and let fire burn.\nSPILL OR LEAK\n•\nKeep combustibles (wood, paper, oil, etc.) away from spilled material.\n•\nDo not touch damaged containers or spilled material unless wearing appropriate protective clothing.\n•\nStop leak if you can do it without risk.\nSmall Dry Spill\n•\nWith clean shovel, place material into clean, dry container and cover loosely; move containers from spill\narea.\nLarge Spill\n•\nDike far ahead of spill for later disposal.\nFIRST AID\nRefer to the “General First Aid” section.\nSpecific First Aid:\n•\nContaminated clothing may be a fire risk when dry.\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 213","truncated":false,"body_characters":3357}
