The reassessment of the non-fire emergency plan should occur due to significant changes pertaining to what?

The reassessment of the non-fire emergency plan is essential when there are significant changes, and the most encompassing reason for these adjustments is due to changes in building occupancy. An increase or decrease in the number of occupants can impact evacuation plans, resource allocation, and emergency response strategies. For example, if a building's occupancy increases, there may need to be a reevaluation of exit routes, stairwell usage, or other safety protocols to ensure everyone's safety during an emergency.

While regulatory updates and changes in city guidelines are important factors to consider, they typically reflect broader legislative or administrative changes rather than the specific and immediate impact of changes in building occupancy. Therefore, the correct focus for reassessing the non-fire emergency plan is on the dynamics of occupancy, which can directly affect how emergencies are managed within the structure.
