1. A firefighter reports a smell of natural gas in a
hallway of a 6-story apartment building. The first
priority for the officer is to:
A. Open all windows to ventilate
B. Evacuate all occupants immediately
C. Shut off the main gas valve and call the utility
company
D. Use a spark-resistant tool to check for leaks
,Rationale: The first priority is to control the source
of gas. Shutting off the main valve and notifying the
utility company is the standard protocol before
ventilation or evacuation, which may occur later but
are not the primary action.
2. During a high-rise fire, the fire department
connection (FDC) is found to be damaged. The
officer should:
A. Abandon the FDC and use standpipes only
B. Connect to the nearest viable FDC, and request
additional pumpers to supplement pressure
C. Attempt to repair the FDC on site
D. Order all firefighters to carry hose up the stairs
Rationale: The FDC is critical for supplying water. If
damaged, the officer must use an alternate FDC and
ensure adequate pressure via additional pumpers.

indicator of potential flashover?
,A. Black smoke turning to brown

indicates that superheated gases at the ceiling are
igniting. This is the most reliable visual warning.

A. Cut the battery cables immediately
B. Maintain a safe distance and use water fog to
cool the battery pack; consider thermal runaway
C. Use a Class C extinguisher only

hazardous.
