Red Seal Construction Electrician Practice Exam

What safety practice should be followed when using ladders near overhead power lines?

1. Use wooden ladders only

2. Maintain at least a 10-foot distance from power lines

3. Ensure the ladder is secured at the base

4. Use a ladder with plastic components

The correct answer is: Maintain at least a 10-foot distance from power lines

Maintaining at least a 10-foot distance from overhead power lines is crucial for safety when using ladders. Power lines can carry significant electrical currents, and coming too close can pose serious electrocution hazards. This distance is recommended as a precautionary measure to ensure that any accidental contact with the ladder or an individual using it does not result in electrical shock or injury. The 10-foot rule is grounded in safety standards and helps to account for various aspects, such as the reach of the ladder and the potential for wind or movement that could inadvertently bring the ladder closer to the wires. Following this guideline significantly reduces the risk of electrical incidents when working at heights near energized conductors. Adhering to this practice reflects an understanding of the dangers associated with working around power lines and emphasizes the importance of maintaining a safe work environment.
