Red Seal Mobile Crane Operator Practice Exam

What are the potential hazards of working near overhead power lines?

1. Increased load capacity

2. Electrocution risks and electrical arcing

3. Unstable ground conditions

4. Noise pollution

The correct answer is: Electrocution risks and electrical arcing

Working near overhead power lines presents significant hazards, particularly the risks of electrocution and electrical arcing. When a crane or any equipment gets too close to these power lines, the potential for electrical current to travel through the air increases, particularly if the equipment makes contact with the lines. This can create an arching effect where electricity jumps from the power line to the equipment or the operator, leading to severe injury or even death. Additionally, power lines carry high voltage, and even a close proximity without contact can result in dangerous situations. Electrocution can occur from direct contact or through indirect means like contacting conductive materials or equipment that then transmit electricity. Understanding and mitigating these hazards is crucial for maintaining safety when working in environments with overhead power lines. Proper risk assessments, maintaining safe distances, and using spotters or warning signs are common practices to ensure safety in these scenarios.
