Ontario Building Code Practice Exam

What is the minimum number of exits required for a commercial building with a capacity of 300 people?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

This is because according to most building codes and safety regulations, a commercial building with a capacity of 300 people would require at least two exits in case of an emergency evacuation. Having only one exit could potentially create safety hazards and cause delays in the evacuation process. Option A is incorrect because it does not meet the minimum requirement for a building with a capacity of 300 people. Option C and D are incorrect because having three or four exits would be excessive and not necessary for a building of this size. It is important to have a balance between having enough exits for safety and practicality in terms of building design and cost.
