SUBSTANCES (Self-Reactive)

POTENTIAL HAZARDS

FIRE OR EXPLOSION

  • Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact.
  • May be ignited by heat, sparks or flames.
  • Some may decompose explosively when heated or involved in a fire.
  • May burn violently. Decomposition may be self-accelerating and produce large amounts of gases.
  • Vapors or dust may form explosive mixtures with air.

HEALTH

  • Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death.
  • May produce irritating, toxic and/or corrosive gases.
  • Runoff from fire control 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.
  • Keep out of low areas.

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 will only provide limited protection.

EVACUATION

Large Spill
  • Consider initial downwind evacuation for at least 250 meters (800 feet).
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.

EMERGENCY RESPONSE

  • Move containers from fire area if you can do it without risk.
Fire involving Tanks or Car/Trailer Loads
  • BEWARE OF POSSIBLE CONTAINER EXPLOSION.
  • Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
  • Cool containers with flooding quantities of water until well after fire is out.
  • Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
  • ALWAYS stay away from tanks engulfed in fire.

SPILL OR LEAK

  • ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
  • Do not touch or walk through spilled material.
  • Stop leak if you can do it without risk.
Small Spill
  • Take up with inert, damp, non-combustible material using clean non-sparking tools and place into loosely covered plastic containers for later disposal.
  • Prevent entry into waterways, sewers, basements or confined areas.

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.
