Q

TB 140 ELEVATOR OPERATIONS AT HIGHRISE

Phase I, “Recall Phase”

Manual or automatic recall of elevators to the lobby or designated recall level of the building either through the operation of a “Emergency Service” key switch in the lobby or fire control room or by the activation of an elevator lobby smoke detector.

In Phase I operation when the emergency operation switch is turned to the “ON” position, all elevator cars are recalled to the lobby (or designated recall floor) automatically.

Phase I, “Recall Phase”

The “Bypass” position is used to place the elevator in operation on a temporary basis when the entire building has been deemed safe for normal use, but there is still enough residual smoke to actuate the detectors or the detectors are malfunctioning. The elevator key is not
removable when the switch is in the bypass position.

Phase I, “Recall Phase”

The 2008 Elevator Code requires a similar three position “Recall” key switch with positions marked “RESET,” “OFF,” and “ON”

To remove the elevators from Phase I Emergency Recall Operation, the switch shall be rotated first to the “RESET” position, and then to the “OFF” position. With this system, there is no means to bypass the alarm system when a fire
protection device cannot be reset.

Phase II, “Override Phase”

Fire service controls within the elevator car itself which allows firefighters to manually control the elevator from inside the car only.

This switch is “normally” a three-position key switch (On-Off-Hold) that becomes operative when the lobby “Emergency Service” switch is in the “ON” position. Turning both switches (Phase I and Phase II) to the “ON” position operates the “Override Phase”.

“on,” “off,” and “hold” key positions in the elevator cars. Older elevator systems may have “fireman service” or “normal” labels, as opposed to “on” and “off.”

Open doors are closed by continuous pressure on the “Door Closed” button, if provided. If a “Door Closed” button is not provided, continuous pressure on the desired floor button will serve to close the doors.

The City of Los Angeles enacted a high-rise retrofit ordinances (effective in 1989) that requires all elevators on all levels in all existing high-rise buildings (except Group R, Division 1 occupancies) open into elevator lobbies which are separated from the remainder of the building, including corridors and other exits, by walls having a fireresistive rating of not less than ___-hour. All lobby openings for elevator doors shall be protected with _____ automatic-closing fire assemblies with magnetic hold-open devices for door closure actuated by any initiating device
located on the floor,

Q

TB 140 ELEVATOR OPERATIONS AT HIGHRISE

Elevator lobbies, except for the main entrance level lobby, are provided with a smoke detector located on the lobby ceiling. All lobby doors are designed to close on actuation of any fire alarm initiating device for that specific floor. Elevator controls are designed so that activation of a lobby smoke detector will cause all elevators serving that lobby and any additional elevator serving that floor to return nonstop to the designated recall floor and then be under manual control only.

Q

TB 140 ELEVATOR OPERATIONS AT HIGHRISE

Before utilizing an elevator, the elevator shaft shall be observed to determine the presence of smoke, fire, or water. Directing a flashlight or thermal imaging camera up between the elevator car and the shaft wall can determine the presence of smoke, fire, or water in the elevator shaft. If the presence of any amount of smoke, fire, or water is detected, the use of the elevator for ascent shall be discontinued.

Q

TB 140 ELEVATOR OPERATIONS AT HIGHRISE

When an engine company is the first fire suppression resource at a high-rise fire, personnel from an additional resource must be on-scene and one member will be assigned and designated as the elevator operator before the elevator is used to go aloft. This additional member can be from an additional company or from a fire suppression certified rescue ambulance.

Q

All members, including the member identified as the elevator operator, utilizing the elevator as a means of ascent shall be equipped with full personal protective equipment; breathing apparatus, portable radio, sound power phone, forcible entry tool, and the appropriate equipment for fire suppression operations or the assigned task.

Prior to going aloft, all members shall have donned their Self Contained Breathing Apparatus (SCBA) facepiece and be prepared to connect to the SCBA regulator when an Immediate Dangerous to Life Hazardous (IDLH) environment is encountered. A dry chemical extinguisher shall remain in the elevator car with the elevator operator

Q

TB 140 ELEVATOR OPERATIONS AT HIGHRISE

A test of Phase II operations should be conducted in the following manner:

  1. Press the door close button until the doors are completely closed. Once closed, depress the door open button until the doors begin opening. Release the button and the doors should immediately close. This test verifies that the door open feature is working as designed. Open doors again to their full open position.
  2. Enter several floors by pushing floor indicator buttons. The buttons should light up, but the elevator doors should not close and the elevator should not move. Elevators without a door close button will proceed to the first chosen floor if floor button is held in a depressed position. Touch
    buttons briefly or use door open button to keep doors open with the elevator stationary during this safety check.
  3. Press the “Reset” or “Call Cancel” button to clear the elevator control panel. Repeat this process a second time to ensure the call cancel feature is operating correctly.
  4. Select the desired floor of termination (two floors below the fire floor or two floors below the lowest activated fire alarm indication), plus a minimum of two additional floors, for precautionary checks, below the designated exit floor. If determined that an elevator is going to be used for ascent, precautionary stops shall be made every five- (5) floors in order to test and confirm that the elevator is properly operating in Phase II as designed. These precautionary stops will ensure that:
  • The elevator stops at the desired floor,
  • The elevator doors remain closed when the elevator stops,
  • The elevator doors open when the door open button is activated,
  • The elevator doors close when the door open button is released, and
  • The elevator is performing Phase II operations as designed.

These precautionary stops shall be conducted even if the bank of elevators being used for ascent does not service the fire floor. If for any reason, the elevator does not perform as designed in Phase II operations, or acts erratically, elevator operations shall be immediately stopped and the Fire Attack Team and the Elevator Operator proceed to an appropriate stairwell.

Q

TB 140 ELEVATOR OPERATIONS AT HIGHRISE

Members using an elevator for ascent should also determine the locations of the stairwells in relationship to the location of the elevator vestibule. This should be accomplished at the first, and subsequent precautionary stops by observing the buildings emergency exit plan located at each elevator lobby landing.

These stairway verification checks should be done above the building lobby level due to the fact that stairs leading to the exterior of the building may be connected by a hallway thus providing misleading information as to where the stairwells actually are in relationship to the ground level exits.

Q
