Red Seal Plumbing Practice Exam

How high may scaffolding be before you need a safety rail?

1. 5 feet

2. 6 feet

3. 7-1/2 feet

4. 10 feet

The correct answer is: 7-1/2 feet

When working on scaffolding, safety is of utmost importance. This means that any height above ground level needs to be properly secured with a safety rail. While options A and B may seem like reasonable heights for scaffolding, they do not meet safety standards. Option D, while higher than option C, is still not the ideal height for a safety rail. Option C, 7-1/2 feet, is the appropriate height where a safety rail is needed according to most regulations and guidelines. Therefore, it is the correct answer.
