Different types of fire extinguishers are designed to fight different classes of fires. The three most common types of fire extinguishers are:
Pressurized water extinguishers are being phased out because they do not work with class B and C fires. They can be used for ordinary combustibles like wood, paper, many plastics, cloth and rubber. Carbon dioxide extinguishers are generally used in areas of sensitive electrical or electronic equipment since it is gas and leaves no residue that will damage the equipment. Carbon dioxide functions by removing or displacing the oxygen in a fire. Dry
chemical fire extinguishers are by far the most common on campus. They
are effective on all three classes of fires. Dry chemicals function by
interrupting the chemical chain reaction of the fire tetrahedron. |
