Ontario Building Code Practice Exam

What is the minimum number of exits required for a residential building with a capacity of 500 people?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 3

This is because according to building codes, the number of exits required for a building is determined by its capacity and occupancy classification. For a residential building with a capacity of 500 people, a minimum of three exits is required for safe evacuation in case of an emergency. Option A may seem like a plausible answer, but having only one exit would greatly increase the risk in case of a fire or other emergency. Option B and D are also incorrect, as two exits would not be sufficient for a building with a capacity of 500 people. It is important to note that the exact number of required exits may vary depending on local regulations and building design.
