Fire Fighting
Small Fires: Use water. Do not use dry chemicals or foams. carbon dioxide or Halon may provide limited control. Large Fires: Flood fire area with water from a distance.
Fire Potential
These substances will accelerate burning when involved in a fire.

Accidental Release Measures

Small spills/leaks
Keep away from combustible materials. Avoid contact unless wearing appropriate protective clothing. Stop leak if you can do it without risk. With clean shovel place material into clean, dry container and cover loosely; move containers from spill area.
