POTENTIAL HAZARDS

HEALTH

  • Inhalation of vapors or contact with substance will result in contamination and potential harmful effects.
  • Fire will produce irritating, corrosive and/or toxic gases.

FIRE OR EXPLOSION

  • Non-combustible, substance itself does not burn but may react upon heating to produce corrosive and/or toxic fumes.
  • Runoff may pollute waterways.

PUBLIC SAFETY

  • CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
  • As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.
  • Stay upwind.
  • Keep unauthorized personnel away.

PROTECTIVE CLOTHING

  • Wear positive pressure self-contained breathing apparatus (SCBA).
  • Structural firefighters' protective clothing will only provide limited protection.

EVACUATION

Large Spill
  • Consider initial downwind evacuation for at least 100 meters (330 feet).
Fire
  • When any large container is involved in a fire, consider initial evacuation for 500 meters (1/3 mile) in all directions.

EMERGENCY RESPONSE

FIRE

  • Use extinguishing agent suitable for type of surrounding fire.
  • Do not direct water at the heated metal.

SPILL OR LEAK

  • Do not touch or walk through spilled material.
  • Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
  • Stop leak if you can do it without risk.
  • Prevent entry into waterways, sewers, basements or confined areas.
  • Do not use steel or aluminum tools or equipment.
  • Cover with earth, sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain.
  • For mercury, use a mercury spill kit.
  • Mercury spill areas may be subsequently treated with calcium sulphide/calcium sulfide or with sodium thiosulphate/sodium thiosulfate wash to neutralize any residual mercury.

FIRST AID

  • Move victim to fresh air.
  • Call 911 or emergency medical service.
  • Give artificial respiration if victim is not breathing.
  • Administer oxygen if breathing is difficult.
  • Remove and isolate contaminated clothing and shoes.
  • In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
  • Keep victim warm and quiet.
  • Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
