20
Q

If the building is equipped with split bank elevators, do not use an elevator that services the fire floor if a lower bank of elevators reaches WITHIN _____ floors of the fire floor.

A

5

Additionally, elevators that travel through a “blind shaft’ should be avoided whenever possible

21
Q

The high-rise retrofit ordinance (effective in 1989) 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 fire-resistive rating of not less than _____.

A

1 hour

22
Q

The high-rise retrofit ordinance (effective in 1989) requires all lobby openings for elevator doors shall be protected with a ______ rated automatic-closing fire assembly with a magnetic hold-open device for door closure actuated by any initiating device (smoke detector) located on the floor.

A

3/4 hour (45 min) rating

23
Q

Before utilizing an elevator, the elevator shaft shall be observed to determine the presence of?

A

-smoke
-fire

Personnel from an additional resource (fire or RA) must be on-scene and one certified member assigned as the elevator operator

(Brings total to FIVE personnel in the elevator)

25
Q

No more than _____ personnel with equipment shall be permitted in any one elevator at a time. This will prevent exceeding the weight capacity of the elevator.

A

26
Q

Utilizing elevator as a means of ascent:

All members, including the elevator operator, shall be equipped with:

A

-Full PPE
-SCBA
-Portable radio
-Sound power phone

28
Q

The initial fire invest team or Lobby Control Unit shall notify the IC of elevator status within the building.

Unaccounted elevators will require the IC to implement an “_________” to determine the location and status of any elevator not returning to its recall location and the potential for extrication and rescue.

A

29
Q

If the circular “fire service,” “fire helmet,” or “Maltese cross jewel” indicator light on the elevator car control panel is blinking, the elevator cars in that bank should not be used.

Why?

A

Impending elevator shutdown due to an elevator shunt switch activation.

• 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.

34

A

At the FIRST , and SUBSEQUENT precautionary STOPS by observing the buildings emergency exit plan located at each elevator lobby landing

35
