Final answer:
In buildings where multiple exits are required, no more than one-half of the total number of exits or total exit minimum width can be horizontal exits, ensuring sufficient direct means of egress.
Step-by-step explanation:
When addressing the requirements for exits in a building, in scenarios where two or more exits are required, not more than one-half of the total number of exits or total exit minimum width shall be horizontal exits. This regulation is designed to ensure that in the event of an emergency, there are sufficient and appropriate means of egress for the building occupants. Horizontal exits, which lead to areas of refuge within the same floor, are part of a comprehensive fire safety and evacuation plan.
While they provide an alternate route, they do not lead directly outside, which is why their proportion is limited in comparison to vertical exits that typically lead directly to the exterior. When multiple exits are required, no more than 50% of the total number of exits or total exit minimum width can be horizontal exits. In terms of fire safety, when multiple exits are required, no more than 50% of the total number of exits or total exit minimum width can be horizontal exits.
