For high-rise building fires, fire elevators can save firefighters energy and enable them to quickly approach the burning floor; For underground building fires, due to current equipment limitations, the danger of entering underground through stairs is higher than that of above ground buildings, and it is necessary to minimize the time to reach the fire site. Setting up fire elevators is conducive to meeting the needs of firefighting operations and fire rescue, creating favorable conditions for firefighting and rescue. Today we will share the relevant content on setting up fire elevators.

1) A high-rise tower with a height greater than 32m and an elevator installed, and no more than 2 people on any working platform on any floor.
2) Class D and Class E factories with a partial building height greater than 32m and a building area of no more than 50 square meters per floor above the partial height.
8. Except for mechanical car garages with no lanes and no personnel staying indoors, car garages with a building height greater than 32m should be equipped with fire elevators. The setting of fire elevators should comply with the relevant provisions of the Building Regulations.
2、 Setting requirements
