Building Fire Safety Flashcards

What is 'stack effect' and why is it relevant to high-rise fire safety?

Answer: The phenomenon where temperature differences cause air (and smoke) to move vertically through a building

Stack effect is the movement of air and smoke upward through vertical openings due to temperature and pressure differences, which can rapidly spread smoke in high-rise buildings.

When conducting a fire watch, what should a Fireguard do if they discover a locked emergency exit?

Answer: Immediately unlock or cause it to be unlocked, and notify the FDNY

Locked emergency exits are an immediate life-safety violation; the Fireguard must immediately have the door unlocked and notify the FDNY.

What is the purpose of a 'standpipe system' in a multi-story building?

Answer: To provide water supply connections for firefighters at each floor

A standpipe system is a network of pipes and hose connections that delivers water directly to firefighters at various floor levels, enabling effective fire attack in tall buildings.

Which of the following actions by a building occupant is most likely to impede firefighting efforts?

Answer: Opening windows to signal their location

Opening windows during a fire allows fresh air in, which feeds the fire and can create dangerous wind-driven fire conditions that threaten firefighters.

How should a Fireguard handle the discovery of an improperly stored flammable liquid (e.g., gasoline) inside a building?

Answer: Require immediate removal and notify the FDNY

Flammable liquids like gasoline are prohibited inside most buildings; the Fireguard must require immediate removal and report the violation to the FDNY.
