Chain Saw Safety Overview

This program provides information regarding the safety requirements of chain saw use.

This program applies to employees who use chain saws while on the job. It does not apply to home use; however, the safety information provided certainly is beneficial to anyone using a chain saw regardless of location.

Departments that have personnel using chain saws must ensure that the equipment provided has the required safety features, personnel using the chain saws have received training on work practices, and are provided appropriate safety apparel

Personnel using chain saws for work-related purposes must attend safety training and follow recommended practices described in this program. OSHA requires that appropriate personal protective equipment be provided by the employer and used by the employee.

Safety Features

Chain saws have many safety features, some of which are voluntary for the manufacturers to implement. If chain saws are used by employees, they must have these three safety features, and they must be in proper working order.

The chain brake stops the chain motion in the event that the operator falls onto the chain saw, or the chain pulls the bar into the tree being cut, reducing the potential for serious injury. It should stop the chain motion when pushed or pulled back towards the handle, and the chain motion should resume when the brake is reactivated.

The throttle and lock safety feature prevents accidental throttle engagement. Both the throttle and lock must be pressed in order for the chain to move.

The chain catcher is a small plastic or metal protrusion that prevents a broken chain from flying back towards the operator. If it is missing or broken, it must be replaced prior to use.
