How can deadly false alarms affect occupant trust?

• A. They improve evacuation efficiency
• B. They cause occupants to ignore or dismiss alarms
• C. They have no effect on life-safety signaling
• D. They speed up system testing

Answer: (B)

Trust in the life-safety signaling system is essential for a prompt and correct response during emergencies. When deadly false alarms occur, occupants may learn to doubt the alarms because they have sounded without a real fire. This undermines their tendency to react quickly, leading to ignoring or dismissing alarms in future events. That hesitation can delay evacuation and increase risk to lives, since the purpose of the alarm is to trigger immediate, appropriate action. The other options don’t fit because effective evacuation relies on alarms people trust and respond to, false alarms do affect life-safety signaling by reducing its credibility, and system testing should be conducted through proper procedures rather than being sped up or driven by false events.
