Fireman's switch
Fireman's switch is a safety device used in electrical installations. The switch is designed to quickly cut off the power supply in the event of a fire, allowing firefighters to safely carry out their duties without the risk of electrical shock.
Functionality[edit | edit source]
The Fireman's switch is typically a red switch located on the exterior of a building or near electrical equipment. When activated, it disconnects the electrical supply, ensuring that firefighters and other emergency personnel are not exposed to live electrical wires while fighting a fire.
Design and Operation[edit | edit source]
The design of a Fireman's switch is typically simple, with a clear indication of its function and operation. It is usually red in color to make it easily identifiable. The switch is often key-operated to prevent unauthorized use. When the key is turned, the switch opens the circuit and disconnects the power supply.
Applications[edit | edit source]
Fireman's switches are commonly found in buildings with large electrical installations such as commercial buildings, industrial facilities, and multi-story residential buildings. They are also used in locations with specific electrical equipment, such as neon signs or high voltage installations, where there is a risk of electrical shock in the event of a fire.
Regulations[edit | edit source]
In many jurisdictions, the installation of a Fireman's switch is mandated by building codes and fire safety regulations. These regulations may specify the locations where a Fireman's switch is required, its design and operation, and the procedures for its use.
