Ontario Building Code Practice Exam

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

1. 750 mm

2. 800 mm

3. 850 mm

4. 900 mm

The correct answer is: 850 mm

The minimum clearance required for a door in an industrial building is 850 mm. This is because industrial buildings often have large machinery and equipment that require wide clearance space for safe and efficient movement. Options A, B, and D do not meet the minimum clearance requirement and may pose a risk for potential collisions or obstructions. Option C is the most appropriate and safe clearance measurement for a door in an industrial building.
