Q

High-Rise Building

A

Building that requires fire fighting on levels above the reach of the department’s equipment. Also known as High-Rise.

2
Q

Standpipe System

A

Wet or dry system of pipes in a large single-story or multistory building, with fire hose outlets installed in different areas or on different levels of a building to be used by firefighters and/or building occupants. This system is used to provide for the quick deployment of hoselines during fire fighting operations.

3
Q

Pressure-Reducing Valve

A

Valve installed at standpipe connection that is designed to reduce the amount of water pressure at that discharge to a specific pressure, usually 100 psi (700 kPa).

4
Q

Shunt Trip

A

A circuit breaker uses as a safety device in an elevator system. When electrical current surges, the device disconnects the power source.

5
Q

Phase I Operation

A

Emergency operating mode for elevators. Recalls the car to the terminal floor lobby or another floor as specified, and opens the doors.

6
Q

Phase II Operation

A

Emergency operating mode for elevators. Allows emergency use of the elevator with certain safeguards and special functions.

7
Q

Air-Inflated Structure

A

Membrane structure that uses air pressure to develop its initial shape, but may not use air pressure throughout the entire, high profile, occupancy; enclosed columns or tubes may be inflated to hold the shape of the structure. This type of structure is often intended to be temporary or movable.

8
Q

Air-Supported Structure

A

Membrane structure that is fully or partially held up by interior air pressure. This type of occupancy often has a wider footprint than air-inflated structures, and may be secured in place with rigid lower walls and cables. This type of structure may be maintained in place over a long duration.

9
Q

Cable Membrane Structure

A

Freestanding structure that uses suspension cables for support. Also known as Cable Covered Structure.

10
Q

Frame Membrane Structure

A

Structure supported primarily by a frame or skeleton rather than by load-bearing walls. Also known as Frame Covered Structure.

11
Q

Institutional Sprinklers

A

Low profile sprinkler system and pendant used with concealed piping in correctional facilities and institutions where tampering of the system mus be discouraged or prevented.

12
Q

Atrium

A

Open area in the center of a building, extending through two or more stories, similar to a courtyard but usually covered by a skylight, to allow natural light and ventilation to interior rooms.

13
Q

NFPA 14

A

Standard for installation of standpipe and hose systems

14
Q

Vertical fire spread is particularly likely with

A

Uninterrupted floor to ceiling glass curtain walls.

15
Q

Codes contain mandatory provisions for the recall (phase 1) of all passenger elevators

A

With a vertical travel greater than 25 feet in the event of fire.

16
Q

The greatest single challenge in controlling fires in underground buildings comes from

A

The difficulty in venting heat and smoke.

17
Q

Smokeproof enclosures are now required for buildings with

A

Levels more than 30 feet (10 m) below the level of exit discharge.
