Safe Operation For Elevators During A Fire
Fire and/or excessive heat on a given building floor, may activate the “elevator call button” and summon the elevator directly to the fire floor. Elevator cars are not fire proof and elevator shaft-ways are not smoke proof. Elevators must not be used to evacuate the building or transfer occupants to safe building areas during an emergency. Occupants should use the stairways for prompt and safe evacuation. For safe elevator operation during emergency situations the following is recommended.
- A central control should be installed in the lobby which when activated will immediately return all elevators nonstop to the lobby and automatically open all doors.
- Provision should be made to manually control all elevators from the lobby central control station.
- Products of combustion automatic sensing devices, responsive to heat and/ or smoke, should be installed in the elevator shafts. When activated the elevator controls should be programmed to return all elevator cars nonstop to the lobby.
- Emergency keys should be available at the lobby central control station, to open elevator doors during an emergency.
- Selected elevators should be provided with a “fireman’s switch” which would permit manual control of individual cars for use by the Fire Department.
- “Class B” fire doors should be provided on all elevator landings.
- Elevator electrical equipment should be placed in conduit or otherwise protected from fire and heat.
