Ontario Building Code Practice Exam

What is the minimum height required for a guardrail on a ramp in an industrial building?

1. 900 mm

2. 1000 mm

3. 1100 mm

4. 1200 mm

The correct answer is: 900 mm

The minimum height requirement for a guardrail on a ramp in an industrial building is 900 mm. This height ensures proper safety measures for individuals using the ramp. Options B, C, and D are higher than the minimum requirements, making them incorrect choices. Option B at 1000 mm and option C at 1100 mm may be suitable for other types of buildings, but not for an industrial building. Option D at 1200 mm is significantly higher than the minimum requirement and may not be practical or cost-effective for most industrial building ramps. Therefore, option A at 900 mm is the most appropriate and accurate answer.
