4. 4

The correct answer is: 3

In determining the minimum number of exits required for a commercial building based on its capacity, the Ontario Building Code stipulates specific criteria to ensure the safety of occupants during emergencies. For a building with a capacity of 500 people, the code typically mandates that at least two exits must be provided, but more may be necessary depending on specific conditions related to the building's design and occupancy type. For a maximum occupancy of 500, the requirement generally escalates to three exits. This is due to the need to ensure safe and efficient evacuation, particularly in cases where the building's layout may pose challenges during an emergency. The Ontario Building Code emphasizes the importance of having multiple exits to minimize congestion and facilitate a swift evacuation. To summarize, the requirement of three exits for a commercial building accommodating 500 people is a crucial aspect of safety regulations outlined in the code, ensuring that occupants can exit the building quickly and safely in the event of an emergency.
