POTENTIAL HAZARDS

FIRE OR EXPLOSION

  • May explode from friction, heat or contamination.
  • These substances will accelerate burning when involved in a fire.
  • May ignite combustibles (wood, paper, oil, clothing, etc.).
  • Some will react explosively with hydrocarbons (fuels).
  • Containers may explode when heated.
  • Runoff may create fire or explosion hazard.

HEALTH

  • TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.
  • Fire may produce irritating and/or toxic gases.
  • Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.).
  • Runoff from fire control or dilution water may cause pollution.
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 in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
  • Keep unauthorized personnel away.
  • Stay upwind, uphill and/or upstream.
  • Ventilate closed spaces before entering.

PROTECTIVE CLOTHING

  • Wear positive pressure self-contained breathing apparatus (SCBA).
  • Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
  • Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.

EVACUATION

Spill

  • See Table 1 - Initial Isolation and Protective Action Distances for highlighted materials. For non-highlighted materials, increase, in the downwind direction, as necessary, the isolation distance shown under "PUBLIC SAFETY".

Fire

  • If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping document and/or the ERAP Program Section.
EMERGENCY RESPONSE

FIRE

Small Fire

  • Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.

Large Fire

  • Flood fire area with water from a distance.
  • Do not move cargo or vehicle if cargo has been exposed to heat.
  • Move containers from fire area if you can do it without risk.
  • Do not get water inside containers: a violent reaction may occur.

Fire involving Tanks or Car/Trailer Loads

  • Cool containers with flooding quantities of water until well after fire is out.
  • Dike fire-control water for later disposal.
  • ALWAYS stay away from tanks engulfed in fire.
  • For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

SPILL OR LEAK

  • Keep combustibles (wood, paper, oil, etc.) away from spilled material.
  • Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
  • Use water spray to reduce vapors or divert vapor cloud drift.
  • Prevent entry into waterways, sewers, basements or confined areas.

Small Spill

  • Flush area with flooding quantities of water.

Large Spill

  • DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.

FIRST AID

  • Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
  • 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.
  • Contaminated clothing may be a fire risk when dry.
  • In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
  • Keep victim calm and warm.
