They can be extinguished by the carbon dioxide, water spray, dry powder, light water, and the vaporizing liquids 4. They may be extinguished by water, wet chemical suppression, or dry chemical powder. Class E fire alarm systems are designed specifically for high-rise office buildings. Different metals require different agents and for a particular metal agents cannot necessarily be substituted for one another. Electrical fires can be caused by faulty equipment, damaged wiring, short circuits, and overloaded switchboards and sockets. Fires that originate from flammable liquids and gas can be extinguished by a class B fire extinguisher. These doors will maintain integrity, stability and insulation for 30 minutes. Chemicals such as FM-200 are now the recommended halogenated suppressant. The items around the electrical sources may burn. The main component of a Class C fire is the electricity that powers these devices. A Class E cargo compartment is one on airplanes used only for the carriage of cargo and in which -.
