Oxidizers (Unstable)
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 may cause environmental contamination.
PUBLIC SAFETY
  • CALL 911. Then call emergency response telephone number on shipping paper. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
  • Keep unauthorized personnel away.
  • Stay upwind, uphill and/or upstream.
  • Ventilate closed spaces before entering, but only if properly trained and equipped.
PROTECTIVE CLOTHING
  • Wear positive pressure self-contained breathing apparatus (SCBA).
  • Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.
  • Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.
EVACUATION
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.
Spill
  • For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
  • For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.
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.
  • If it can be done safely, move undamaged containers away from the area around the fire.
  • 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
Refer to the "General First Aid" Section
Specific First Aid:
  • Contaminated clothing may be a fire risk when dry.
