OSHA 30 Hour Construction Program Practice Test

Which precautions can help avoid powerline hazards?

1. Keeping a distance of at least 10 ft, marking with warning signs, using wood ladders

2. Wearing rubber boots, installing underground cables, using metal ladders

3. Using drones for inspection, avoiding plastic tools, employing spotters only

4. Installing automatic shut-off, using insulated gloves, relying on visual checks

The correct answer is: Keeping a distance of at least 10 ft, marking with warning signs, using wood ladders

Keeping a distance of at least 10 feet from power lines is crucial because this distance helps protect workers from electrical hazards, as high-voltage electricity can jump or arc through the air. Marking areas with warning signs alerts workers to the presence of nearby power lines, ensuring increased awareness and caution. The recommendation to use wood ladders is based on the fact that wood is a non-conductive material, which further reduces the risk of electrical shock when working in proximity to power lines. These precautions collectively promote a safer work environment by addressing both equipment safety and awareness of hazards in the area.
