Hand lines must have a minimum diameter of _____ and a breaking strength of _____.

The minimum requirements for hand lines are crucial to ensure safety and functionality when working at heights, especially in the context of lineman operations. A hand line with a diameter of 1/2 inch and a breaking strength of 5,400 lbs strikes the right balance for strength and handling capability.

The specified diameter provides enough thickness to handle the stress associated with lifting tools and equipment, while still being manageable for workers to maneuver. The breaking strength of 5,400 lbs ensures that the line can safely support not only the weight of tools but also account for dynamic loads and any potential sudden jerks that might occur during use. This combination reduces the risk of equipment failure, which can lead to accidents or injuries during lineman activities.

By adhering to these specifications, linemen can work with greater confidence in the equipment they rely on, ultimately contributing to higher safety standards in the field. This information is part of a larger body of knowledge essential for linemen to protect themselves and their teams while working under potentially hazardous conditions.
