OSHA 30 Hour Construction Program Practice Test

Why must protruding reinforcing steel be guarded?

1. To prevent slipping hazards

2. To eliminate impalement hazards

3. To enhance visual appearance

4. To maintain structural integrity

The correct answer is: To eliminate impalement hazards

Protruding reinforcing steel must be guarded primarily to eliminate impalement hazards. This safety measure is crucial because exposed rebar can pose a significant risk to workers on construction sites. If a person falls or comes into contact with protruding rebar, the sharp ends can penetrate and cause serious injury, which is referred to as an impalement hazard. Guarding these protrusions can involve covering them, bending them down, or using protective caps to minimize the risk of injury. This focus on eliminating impalement hazards is a fundamental aspect of workplace safety, particularly in construction environments where such hazards are prevalent. While factors like preventing slipping hazards, enhancing visual appearance, and maintaining structural integrity might be considerations in different contexts, the primary concern with guarding protruding rebar is specifically to safeguard workers from potential injury caused by impalement.
