What is the maximum allowable time for the evacuation pause during a fire alarm?

The maximum allowable time for the evacuation pause during a fire alarm is established to ensure a balance between preventing false alarms and maintaining safety. A pause of 15 seconds is specified to allow occupants the time to respond to alarm conditions without increasing the risk of exposure to fire or smoke. This time frame provides a brief window for individuals to assess the situation while still prioritizing a timely evacuation.

In general, extending this time could lead to confusion or delay in evacuating a building, which can be critical during an actual fire event. Keeping the evacuation pause to a maximum of 15 seconds ensures that any necessary actions, like confirming the validity of the alarm, do not significantly compromise safety. This standard is aligned with best practices in fire safety regulations, aiming to protect lives effectively.
