Ontario Building Code Practice Exam

The minimum number of exits required for a commercial building with a capacity of 200 people is 2. This is to ensure that there are enough exit points for individuals to safely evacuate the building in case of an emergency. Option A is incorrect because only one exit would not be sufficient for a building with 200 people, as it could lead to congestion and delays in evacuation. Option C is incorrect because although the number of exits may vary depending on the building layout, a minimum of 3 exits is typically required for buildings with a capacity of 500 or more people. Option D is incorrect because having 4 exits may exceed the necessary requirements and can create confusion during an emergency. Therefore, option B is the most appropriate answer as it satisfies the minimum requirement while also considering the building's capacity.
