Question: 1 / 400

What are the two primary factors that determine the number of exits in a room?

Exit width factor and occupancy

Occupant load and occupancy

The number of exits in a room is primarily determined by occupant load and occupancy type. Occupant load refers to the maximum number of people that can reasonably occupy a space, which directly influences safety and egress requirements during emergencies. The occupancy type indicates the nature of the activities that will take place in the space and helps establish the level of hazard associated with the use of that area.

Different occupancy types have specific codes and requirements regarding exits to ensure safe evacuation in case of emergencies. Therefore, the combination of these two factors is crucial in determining the adequacy of exit provisions in any given space. Other factors, like exit width or travel distance, do play a role in the overall safety strategy, but the fundamental determinant hinges on the relationship between the number of occupants and the type of occupancy.
