Abstract: A wood pole fall protection device for line technicians and pole climbers that allows travel up and down a wooden pole without incurring a fall or injury. The wood pole fall protection device is also designed to provide the line technician with the ability to rotate or twist in the straps as well as negotiate and maneuver around obstacles and obstructions encountered upon the pole.

Abstract: A retaining device is disclosed for attaching a chainsaw to a worker, working aloft. The retaining device provides a tear-away component between two sections of a lanyard. When the chainsaw is pinched in a falling limb, the slow, tearing motion of the tear-away component results in a minimal amount of impact force being exerted on a worker. In the event the tear-away component pulls apart entirely, the chainsaw is released from the worker and falls to the ground with the limb. The worker maintains his/her position within the structure. Alternatively, if the chainsaw is dropped by the worker, it will fall below the feet of the worker, allowing him/her to retrieve the chainsaw. A bystander below will not be hit by the falling chainsaw.
