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.\nStay upwind, uphill and/or upstream.\nKeep unauthorized personnel away.\n•\n•\n•\nPROTECTIVE CLOTHING\n•\nWear positive pressure self-contained breathing apparatus (SCBA).\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 downwind evacuation for at least 50 meters (160 feet).\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 270\nERG 2024\n\nMetals (Powders, Dusts, Shavings, Borings,\nTurnings, or Cuttings, etc.)\nGUIDE\n170\nEMERGENCY RESPONSE\nFIRE\n•\nDO NOT USE WATER, FOAM OR CO2.\n•\nDousing metallic fires with water will generate hydrogen gas, an extremely dangerous explosion hazard,\nparticularly if fire is in a confined environment (i.e., building, cargo hold, etc.).\n•\nUse DRY sand, graphite powder, dry sodium chloride-based extinguishers, or class D extinguishers.\n•\nConfining and smothering metal fires is preferable rather than applying water.\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\nIf impossible to extinguish, protect surroundings and allow fire to burn itself out.\nSPILL OR LEAK\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.\n•\nPrevent entry into waterways, sewers, basements or confined areas.\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 271","truncated":false,"body_characters":2976}
