Course Completion Requirements

Climbing Equipment and Tools

Climbing equipment for lineworkers is referred to as personal climbing equipment because it is sized for the individual and provides for his or her safety. Because of these personal safety
factors, climbing equipment should only be used by that person. This ensures that the lineworker always knows the condition of their equipment.

Participants must bring their own climbing equipment, including climbers, body belt, personal fall arrest system with a secondary safety device, and climbing boots to use during the program. Participants will also be required to bring their own personal protective equipment including hardhat, safety glasses, rubber gloves with protectors, work/climbing gloves, and long-sleeve shirts. It is the individual’s responsibility to ensure that their equipment is maintained in a safe manner by inspecting each piece prior to each use, as well as performing periodic inspections and routine maintenance during the duration of the program.

Instructors reserve the right to inspect and determine if the personal climbing equipment is adequate for use. Personal climbing equipment and hand tools should be marked with the
participant’s name. TEEX is not responsible for any loss or theft of personal climbing equipment, hand tools, or classroom supplies.
