A fire-proof elevator is one that is designed with safety in mind. Normally, this type of elevator has automatic safety features, such as expanding and locking beds, but some models are also equipped with emergency stop buttons. These features prevent people from being trapped in the elevator, preventing them from escaping during an emergency.
A fire-proof elevator is also equipped with smoke and fire-detection equipment. These devices need to meet the minimum fire-resistance requirements of the 2010 National Building Code. They must be installed on elevator shafts that have at least 20 minutes of fire resistance. They must also be air and smoke-free.
In addition to fire-resistant doors, fire-proof elevators should have fire-resistant shafts. These are typically great flues that extend from the basement to the roof. They have openings on each floor and are usually adjacent to stairways. In the event of a fire, this feature can help firefighters work more efficiently.
To be considered a fire-proof elevator, the elevator shafts must be separated and positioned in a building with a fire-resistant rating of 120 or higher. A fire-fighting elevator must also have a clear service area for each floor. It should also be able to reach every floor of the building.
Moreover, fire-proof elevators should have a lobby that protects occupants from fire and offers a refuge for people with disabilities. Smoke-proof elevator shafts must also be pressurized against smoke infiltration. This prevents smoke from moving through the elevator shaft and minimizes pressure differences across the hoistway door.
The smoke detection system should work well with the smoke management system in the building. Properly installed smoke detectors can also increase the chances of occupant survival. Ultimately, fire-proof elevators can reduce insurance costs and liabilities for senior residences. It is also a way for insurers to reduce owner-insurance rates and liabilities in their fire-proof buildings.
Fire-proof elevators are becoming more common in many buildings. A fire-proof elevator is constructed with noncombustible materials. Its emergency exits should be clearly marked. This makes it easy for people with disabilities to evacuate the building. A fire alarm system with early warning aspirating smoke detection can help as well.
The current practice of cautioning occupants not to use elevators in fire emergencies reduces the level of trust people have in the system. Moreover, if the elevator car is overcrowded, it may not be able to function properly, and the occupants may be forced to wait at the floor for an indefinite period.
In addition to sprinklers, elevators that are equipped with early warning air aspirating detectors should also be equipped with oxygen cylinders. This will increase the likelihood of an emergency evacuation and reduce the number of people who may be exposed to smoke.
