In an atrium building, which smoke management strategy uses large exhaust fans to remove smoke from the atrium space at a rate sufficient to keep the smoke layer above occupied floors?
Answer: Atrium exhaust
Atrium exhaust (also called smoke exhaust) removes hot gases and smoke from the top of the atrium to maintain a tenable smoke-free layer at lower levels.
A door used as a means of egress must swing in the direction of egress travel when serving a room or area with an occupant load of at least how many persons?
Answer: 50
Doors serving areas with an occupant load of 50 or more must swing in the direction of egress travel per IBC and NFPA 101.
Which exit component provides a protected path of travel between a building's interior and a public way that is separated from the interior by rated construction?
Answer: Exit passageway
An exit passageway is a horizontal component of the exit system that is enclosed by fire-rated construction and connects to a public way.
Under IBC, what minimum fire-resistance rating is required for exit enclosures (stairways) in buildings four or more stories in height?
Answer: 2 hours
IBC requires exit enclosures in buildings four or more stories to have a minimum 2-hour fire-resistance rating.
What term describes the systematic, controlled process of moving occupants from a building in danger to a safe location during an emergency?
Answer: Staged evacuation
Staged evacuation involves moving occupants in phases—typically beginning with the fire floor and adjacent floors—rather than evacuating the entire building simultaneously.
Which life safety system component automatically closes fire doors held open by magnetic door holders upon receiving an alarm signal?
Answer: Electromagnetic door holder release
Electromagnetic door holders release their hold on doors when they receive a signal from the fire alarm control panel, allowing the door closers to shut the doors.
What is the minimum illumination level required at the floor level for means of egress lighting under NFPA 101?
Answer: 1 foot-candle
NFPA 101 requires means of egress to be illuminated at not less than 1 foot-candle at floor level along the path of egress.
