5.5 Cabin doors and elevator shafts for firefighters

Cab doors and elevator shafts must meet the requirements of GOST R 53296.

5.6 Lift control system for firefighters

The elevator control system must ensure the following modes:

- "Fire hazard" (phase 1),

- “Transportation of fire units” (phase 2).

5.6.1 The operating mode of the "Fire hazard" elevator. The elevator must be switched to the "Fire hazard" mode (phase 1) by command from the automatic fire alarm system of the building (structure), upon receipt of which the elevator car must be sent to the main landing floor. In case of detection of dangerous fire factors by the automatic fire alarm system on the main landing floor, a command to move the elevator car to another (alternative) designated floor is permissible. This possibility should be agreed upon when ordering the elevator.

Additionally, it is possible to install a special switch marked with an icon (see Appendix A) and located in the elevator hall on the main landing floor at a distance of not more than 2.0 m horizontal from the edge of the doorway of the elevator for firefighters at a height of 0.9-1.8 m . The special switch must have the positions "0" and "1", the transfer of which with the key according to, listing a), from the position "0" to the position "1", the elevator must switch to the "Fire hazard" mode (phase 1) . Appliances and elevator devices located on storeys and doors of the mine (photocells, touch buttons, etc.), which may be affected by smoke and elevated temperatures, should not prevent the elevator from switching to the "Fire hazard" mode. When the "Fire hazard" mode is activated, all safety devices must remain in working condition, with the exception of the doorway control device, as well as the control of unauthorized entry into the mine. When the elevator is in the “Revision”, “Control from the machine room” modes, as well as when the electrical contacts of the safety circuit are triggered in the event of a fire in the building, the audible sound signal to indicates to the operating personnel the need, if possible, put the elevator in the "Normal operation" mode. This will allow you to execute the command to enable the "Fire hazard". The sound signal can be stopped after the elevator is switched on in the "Fire hazard" mode. After receiving the command in, the elevator control system for firefighters automatically switches to the "Fire hazard" mode (phase 1). In the "Fire hazard" mode (phase 1), the algorithm of the elevator for firefighters provides the following:

a) all newly received orders in the elevator car and calls from floor floors are not recorded and are not accepted for execution,

b) all previously registered orders and calls are canceled,

c) the elevator located on any floor must close the doors and without intermediate stops follow the main landing (designated) floor,

d) an elevator moving in the direction from the main landing (designated) floor must stop on the next floor without opening doors, change direction and follow the main landing (appointed) floor,

e) an elevator moving in the direction of the main landing (designated) floor must continue its movement without intermediate stops on the main landing (designated) floor,

f) upon arrival of the elevator for firefighters on the main landing (designated) floor, the doors of the cabin and the shaft automatically open and remain in the open position.

Further movement of the elevator car for firefighters can only be carried out by order issued by firefighters from the control post in the elevator car firefighters in the mode "Transportation of fire units" (phase 2),

g) the transition of the elevator to the "Fire hazard" mode should be independent of the failure of passenger elevators associated with the elevator for firefighters by general group management.

i) two-way speakerphone according to GOST R 53780 must remain in working condition. The command to switch to the "Fire hazard" mode for each elevator, including the elevator for firefighters, even if the elevators are combined by a group control system, is given separately.

5.6.2 Operating mode of the elevator "Transportation of fire departments" In the "Transportation of fire departments" mode, the operation algorithm of the elevator for firefighters provides the following:

a) the inclusion of the "Transportation of fire departments" mode (phase 2) is carried out after the completion of the "Fire hazard" mode (phase 1).

The operation of the elevator in the "Transportation of fire departments" mode should not depend on the failure of passenger elevators associated with the elevator for firefighters by general group management.

The elevator must be switched to the "Fire Department Transportation" mode using a universal key inserted into the triangular key, located on or near the control panel. The universal key is rotated from the "Off" position (position "0") to the "On" position (position "1"). The universal key should be able to be removed from the slot only in position "0",

b) an order for movement is submitted by pressing the order button on the control panel with the number of the desired floor. After pressing the button, the doors should begin to close, while the order button must be kept pressed until the doors are completely closed. Releasing the button during the closing process should automatically open the door. It is allowed to close the doors using the special button "Closing doors", and the actions with this button should be similar to those described with the order button. Only one order can be submitted and registered. The registered order must have a light indication at the cab control post,

c) the location of the cabin must be displayed on the light displays in the cabin and on the floor of the entrance of the firefighters into the building,

d) during the movement of the cab according to the registered order, it is possible to cancel it and register a new order,

д) открывание дверей остановившейся на этаже кабины возможно только путем постоянного нажатия на кнопку открытия дверей. Если до полного открытия дверей нажатие на кнопку открытия дверей прекращается, то двери должны автоматически закрываться,

f) when the doors are closed, moving the key in the cab from position "1" to position "0" should automatically put the elevator in the "Fire hazard" mode,

g) when the key is transferred from position "1" to position "0" when the elevator car is on any floor with the doors open in the "Fire Department" mode, the cab remains in this position and no orders are issued until the key is moved to position "1 ",

i) doorway control devices, means to prevent the cab from starting during unauthorized entry into the elevator shaft, safety contacts for controlling the closing of the cabin hatch must be disconnected in the "Transportation of fire departments" operating mode,

j) in the mode "Transportation of fire departments" (phase 2), two-way loud-speaking communication according to 5.8.1 must remain in working condition,

k) upon completion of the elevator operation in the "Fire Department Transportation" mode, the elevator movement becomes possible after the elevator returns to the "Normal Operation" mode. The elevator must be returned to the “Normal operation” mode only after an authorized person inspects the elevator and identifies no damage to the elevator.

5.7 Lift communication system for firefighters

5.7.1 The elevator car for firefighters must be equipped with means for connecting to the two-way communication system and for ensuring communication in the "Fire department transportation" mode (phase 2) between the control room or the central control panel of the fire protection system (CPA SDR), if any , and an elevator car, as well as with the main landing floor.

5.7.2 Intercom communication from the elevator car should be carried out without the use of handsets.

Installation in buildings

The following types of buildings are equipped with an elevator for moving fire departments:

  • any buildings, with the exception of apartment buildings, in height exceeding 28 meters,
  • modern apartment buildings with a height of 50 meters,
  • children's educational institutions with a height of 5 meters,
  • hospitals with a height exceeding 5 meters,
  • specialized centers for the elderly and disabled with a height of 5 meters,
  • steel buildings of various institutions for children, the height of which is more than 5 meters.

Installation of a fire elevator requires mandatory consideration of some nuances. Before installing it, the ways of movement of the rescue crews arriving in the event of an emergency at the ignition site are preliminarily studied. This ensures their direct access from the elevator cabin to all possible points of the building.

Firefighters of this type are most often installed in a dedicated hall or are located next to cabs for carrying passengers. At the same time, they are combined into a group with a single control. In a quiet time, these elevators can be used to transport goods and passengers.

Devices are necessarily equipped with horizontally sliding doors that have automatic control. The installed elevator must function properly even when excess pressure appears in the shaft due to smoke ventilation. The floor of the elevator car has a non-slip coating, and in the vicinity of the location of the fire elevator there is an emergency exit to the stairwell.

Design Features

The elevators for moving the fire brigade according to the type of control differ from simple elevator cabins. The roof of the fire device is equipped with a hatch for evacuating people, and the elevator itself is controlled only with the help of push buttons, since the use of touch type buttons is not allowed.

In the event of a fire, the doors of such an elevator open very slowly after a command is given from a fireman in the interior of the cab. This is done to quickly assess the main situation on the floor and instantly close the doors of the elevator car.

The fire lift has a special advanced fire control system. When a fire appears, all cabins immediately descend to the first floor of the building and open before the firemen appear.

When the fire system is running, they are blocked. Unlock requires the key used by firefighters. Today, every modern elevator manufacturer uses his own key, activating the mode of moving fire brigades.

Therefore, special safes are equipped in the building, in which keys suitable for a particular device model are placed for rescue units.

In accordance with generally accepted requirements, the elevator for moving firefighters is equipped with durable fireproof doors that can withstand flame for at least an hour.

Work Schedule and Documentation

The operation of modern firefighting elevators is regulated by the following documents:

  • GOST 52382–2010 “Lifts for the movement of passengers and elevators for the operation of fire services”,
  • GOST 53296–2009 “Installation of modern firefighting elevators in buildings”,
  • GOST 22.9.11–2013 “Safety in case of fire. The use of rescue equipment to evacuate people from modern buildings ”,
  • GOST 28911 “The design of modern elevators for moving firefighters must fully comply with the established norms and rules”,
  • GOST 3047.1 "A fire elevator must be equipped in a separately enclosed mine, enclosed by a structure with a high degree of fire resistance",

In accordance with the adopted standards, non-combustible materials are used for the manufacture of firefighting elevators. This equipment can support at least 1000 kg of weight and is created at least 1100 mm wide, as well as 2100 mm deep for better placement of the stretcher in the interior of the cab.

The modern fire elevator is equipped with a backup type of power and a laid cable that provides communication with the working fire service. In a building of various heights, a modern fire elevator rises to the upper floor in a minute.

Its cabin is equipped with a ceiling hatch for the quick evacuation of rescuers stuck in the mine, as well as a durable gangway that allows you to quickly go up to the next floor in case of trouble. Also, brackets are installed in the interior of the mine, with which the ladder is replaced.

The elevator shaft has a high level of fire resistance and at least two hours after a fire allows the cabin to move safely. Cab doors are kept open by pressing a special button.

After it is released, the doors immediately close, which provides the necessary safety when the cab stops on a flame-flooded floor.

In the lobby, on the main floor, near the location of the entrance to the elevator cabin, a special niche or a metal cabinet with a portable staircase is placed. They are equipped with a metal door, which is closed with a special key, which allows the elevator to be put into operation for the transportation of fire brigades.

The shafts of modern firefighting elevators located in the underground and basement rooms of a high-rise building are necessarily equipped with modern ventilation systems, with the help of which smoke quickly spreading through the floors is eliminated.

In modern buildings, when a fire occurs, elevators to move firefighters greatly facilitate their actions and help to quickly evacuate people. Mandatory equipping of some high-rise buildings with such cabins is provided for by Russian law.

Key parameters and dimensions

I must say that in practice, such an engineering system, necessary for many buildings, structures, to this day remains quite rare in most cities of the country. Why is this the case, it is worthwhile to understand in more detail to understand the essence of the problem.

The safety standards referred to as GOST “Fire Lifts” include the following official documents in force in Russia today:

  • GOST R 52382-2010, which defines the requirements for the design of such elevators, the safety of people during transportation.
  • GOST R 53296-2009, which regulates the installation of these elevators in buildings, structures.
  • GOST R 22.9.11-2013, where the classification list is established, the technical requirements for emergency rescue equipment for saving people from high-rise buildings in case of emergencies, including the elevator ACS installed outside the buildings.

In addition to them, the installation, operation of fire lifts in buildings / structures is regulated by:

  • Art. 90 Federal Law No. 123-Federal Law, requiring the availability of means of raising employees of fire departments to the floors of buildings.
  • SNiP 21-01-97 *, which regulates the safety requirements for all buildings.
  • SP 118.13330.2012 * on public buildings / structures.
  • SP 54.13330.2016 on residential apartment buildings, where under certain conditions the installation of such elevators is also necessary.
  • NPB 250-97, establishing a list of requirements for elevators for the delivery of fire departments mounted in buildings, structures for any purpose.

Among the main characteristics of these devices, you must know the following:

  • A fire elevator is an internal or external technical device equipped with protection, control, and communication installations, which allows for the safe and prompt delivery of firefighters, rescue units to floors / elevations of protected objects.
  • The dimensions of the elevator must be no less than 1.1 x 2.1 m, so that it is possible to transport a stretcher with non-walking patients, as well as disabled people in wheelchairs from buildings for medical and preventive purposes, in the cabin.
  • The width of the construction opening of the mine, as well as the cabin door of such an elevator must be at least 800 mm.
  • The capacity of fire lifts should be at least 630 kg in high-rise residential buildings, 1000 kg - in public buildings, production facilities, structures.
  • The speed of movement of a fire elevator must be at least N / 60 (N - the height of a residential / public building, engineering, technological structure).
  • Reliable operability of smoke ventilation systems of mines, halls of fire elevators, their blocking with APS installations, i.e., automatic activation upon operation smoke sensors, heat detectors.

Important : in addition to the period of intended use during reconnaissance, localization / elimination of flames in the building, a fire elevator can be operated as a passenger or commercial elevator.

Design requirements

The shaft of such a device, both located inside the building and attached to the outside, must be made of non-combustible building materials so that the fire resistance of building envelopes is not lower than REI 120. In addition to the door, it is permissible to carry out technological openings for supplying utilities: power supply systems , control / communication, ventilation systems, provided that they are filled fire hatches, fireproof plaster the entire thickness of the walls / partitions.

The building structures of the fencing of the halls / vestibules of these elevators are carried out by fire-prevention partitions of type 1 with smoke and gas-tight doors of type 2 with self-closing devices, as well as sealing of the narthex.

The fencing structures of the engine rooms of such elevators are carried out by fire barriers - not less than REI 120, and their doors - not less than EI 60.

Although according to PB standards, elevator doors can have fire resistance limits of at least EI 30, but fire doors systems for lifting fighters of fire brigades to floors / marks of buildings must be at least EI 60.

In addition, to the performance, configuration, device of such elevators, there are certain requirements of safety standards / rules:

  • The fencing elements of the elevator car structure are made of non-combustible materials, or belonging to group G1, and the interior decoration / cladding is not lower than G2.
  • Providing backup power for category 1 power supply to prevent stopping / blocking while driving.
  • Installation of a communication line / cable from the cab to the exterior wall of the building to ensure constant contact with the fire extinguishing manager.
  • A ceiling hatch and a gangway are equipped in the elevator car to provide the possibility of lifting to the nearest floor / elevation of the structure, and inside the shaft - brackets.
  • Elevator doors can be in the open state only when the button is pressed, closing if released, which further ensures the safety of people in the cab.
  • The presence of an overload alarm device in the cab.

The design, the material of the floor trim of the fire-lift cabin must be anti-slip on a wet surface.

Building Installation Rules

Elevator for transportation of fire departments when dividing the building into fire compartments without fail is established in its each part. When using steel building elements during the construction of the elevator shaft fire protection of metal structures to ensure the required limit of resistance to fire.

Installation of such elevators is carried out during the construction of buildings / structures, reconstruction of existing ones, replacement of passenger elevators that have developed their operational life.

A fire elevator usually should not connect the ground and underground levels of a building / structure. It is permissible to have stops at the ground and two underground levels, including the basement. If there are three more underground levels in the building, the installation of a separate fire elevator with stops at each elevation of the building or structure is required.

Not only the shafts of such elevators, but also the halls / vestibules in the underground floors are equipped with independent ventilation systems / installations that create excessive pressure of the air displacing smoke from them.

With the provision of buildings, industrial facilities with water stationary fire extinguishing systems mounting sprinkler or deluge irrigators in the halls, vestibules of fire lifts, and also directly in front of them at the elevation / floor is unacceptable.

At the same time, these premises are protected by fire detectors of the building APS installation.

Operating modes

There are three modes. Fire standards for elevators say the following:

  • Carriage of passengers in normal everyday mode.
  • “Fire hazard” is the mode of the established sequence of actions of the control system that prescribes its forced movement to the main floor of the passenger boarding, except for commands directly from the cockpit and calls coming from floors / marks along the way. Upon arrival at the landing, as a rule, the first floor the elevator stands with the door (s) open until the arrival of the first fire brigade.
  • "Transportation of fire departments" - an algorithm that ensures the movement of the elevator, exclusively on the instructions of firefighters from the cab. This does not happen with the touch panel, but only with the help of a push not fixed button. At the same time, the doors do not open automatically upon arrival at the selected elevation of the building, but only on command from the cockpit. The opening is not fast, which gives firefighters the opportunity to assess the situation, give a command to close the doors in case of immediate danger.
