Ontario Building Code Practice Exam

Which of the following is not required for a barrier-free entrance in a commercial building?

1. Ramped approach

2. Automatic door opener

3. Minimum width of 0.9 meters

4. Level landing at entrance

The correct answer is: Minimum width of 0.9 meters

A ramped approach, an automatic door opener, and a level landing at the entrance are all required for a barrier-free entrance in a commercial building. However, a minimum width of 0.9 meters is not required. This width is typically required for wheelchair accessibility but may vary depending on local building codes and regulations. Other factors such as ease of movement for pedestrians and emergency exits may also be considered when determining the width of a barrier-free entrance. Therefore, the minimum width of 0.9 meters is not always necessary for a barrier-free entrance in a commercial building.
