Ontario Building Code Practice Exam

What is the minimum width required for a ramp in a commercial building?

1. 0.9 meters

2. 1.2 meters

3. 1.5 meters

4. 1.8 meters

The correct answer is: 1.2 meters

A ramp in a commercial building is a sloped surface used for wheelchair access, and it must be wide enough to accommodate the required space for a wheelchair to comfortably move up and down. Option A has a width of only 0.9 meters, which may be too narrow for a wheelchair to make sharp turns or for someone to assist a wheelchair user. Option C has a width of 1.5 meters, which may be adequate, but it is not the minimum requirement. Option D has a width of 1.8 meters, which may be too wide and may take up unnecessary space in the building. Therefore, option B with a minimum width of 1.2 meters is the correct answer. It provides the necessary space for a wheelchair and allows for a smooth and safe movement.
