Common hazards (high level)
  • Flammable/combustible material.
  • May ignite on contact with moist air or moisture.
  • May burn rapidly with flare-burning effect.
  • Some react vigorously or explosively on contact with water.
  • Some may decompose explosively when heated or involved in a fire.
  • May re-ignite after fire is extinguished.
  • Runoff may create fire or explosion hazard.
  • Containers may explode when heated.
First actions (field-minded)
  • CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
  • Stay upwind, uphill and/or upstream.
  • Keep unauthorized personnel away.
  • Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters
  • 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
