Why is it important to know the different classes of fire?
The fire classes help determine the best method of extinguishing the fire, help insurance companies understand loss, and help you understand the best method of cleaning the fire damage.
Why can’t you use certain fire extinguishers on certain fires?
Certain fires result from chemical reactions and adding other chemicals can cause further reactions to take place. These reactions may combust the fire further.
Why can’t you use certain chemicals to clean fire damage?
The residue from fire damage can be made up of toxic chemicals and can react with cleaning products to cause harmful reactions or toxic chemicals. Some of these byproducts can be airborne, and some can be surface-bound.
