Fire brigade lifts are passenger lifts that can be used by the fire brigade for firefighting and rescuing people in the event of a fire. In high-rise buildings (i.e. according to MBO § 2 para. 4 no. 1 in buildings from 22 m high) a fire brigade lift must be installed, further requirements for fire brigade lifts in high-rise buildings are regulated by the Model High-Rise Directive (MHHR). In addition, fire brigade lifts are often also required in special buildings or public buildings, e.g. in hospitals.
New fire brigade lifts must be designed in accordance with DIN EN 81-72. According to this, fire brigade lifts must in particular:
- serve all floors of the building
- at all stops and be marked with a corresponding pictogram in the car
have - a fire-protected vestibule (= safe area) on each floor, the area of the vestibule is based on the requirements for the transport of stretchers and the arrangement of the doors
- be structurally protected from smoke transmission into the fire-protected vestibule and the shaft
- reach the furthest floor within 60 seconds after closing the doors from the fire brigade access level
- have a driving cabin of 1.10 x 1.40 m with a load capacity of 630 kg, in the case of two-sided access or when used for evacuation and carrying stretchers and beds, a driving cabin of 1.10 x 2.10 m with a load capacity
- of 1,000 kghave an emergency flap on the car ceiling accessible from the inside with a minimum size of 0.40 x 0.50 m, which allows a firefighter to get out of

- Have a communication system for the fire brigade and a backup power supply
- Have protective measures for all electrical equipment in the shaft and on the car, against dripping and splashing water as well as against stagnant water in the elevator shaft
