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

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

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

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

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.
