Which precaution is vital when back-poling is permitted?

The allowance for back-poling involves specific precautions that ensure safety and effectiveness during operation. Limiting the distance to 80 feet is particularly critical because it helps to maintain control over the pole and reduces the risk of accidents. When the distance is kept within this limit, it minimizes the chance of the pole becoming unwieldy or difficult to handle, which can lead to safety hazards for the crew and surrounding personnel.

Considerations for distances greater than 80 feet could introduce complications such as difficulty in maneuvering the pole, increased chances of it getting caught on obstacles, or strain on the equipment that could result in damage or injury. Therefore, adhering to this precaution is vital for maintaining safety standards and effective operational practices in back-poling scenarios.

Other options, while they have merit in their contexts, do not specifically address the critical nature of distance limitation as it relates to controlling the pole and ensuring a safe working environment.
