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.
