Ontario Building Code Practice Exam

What is the minimum clearance required for a toilet in an industrial building?

1. 400 mm

2. 450 mm

3. 500 mm

4. 550 mm

The correct answer is: 500 mm

The minimum clearance required for a toilet in an industrial building is 500 mm. This is because industrial buildings typically have higher occupancy rates and larger crowds, so more space is needed for individuals to move around and use the facilities comfortably. Option A and B are incorrect because 400 mm and 450 mm may not provide enough space for individuals to use the toilet comfortably, especially if the building is crowded. Option D is also incorrect because 550 mm is more space than necessary for a toilet in an industrial building, and may result in wasted space and increased construction costs.
