Operating a chainsaw is inherently hazardous. Potential injuries can be minimised by using proper personal protective equipment and safe operating procedures.
Before starting a chainsaw
- Check controls, chain tension, and all bolts and handles to ensure that they are functioning properly and that they are adjusted according to the manufacturer’s instructions.
- Make sure that the chain is always sharp and the lubrication reservoir is full.
- Start the chainsaw on the ground or on another firm support. Drop starting is never allowed.
- Start the chainsaw at least 10 feet from the fuelling area, with the chain’s brake engaged.
- Wear PPE such as hard hat, hearing protection, eye protection mesh visor, safety goggles or glasses, gloves, chainsaw boots and clothing including leggings made of long-fibre, chain-clogging fabric.
Fuelling a chainsaw
- Use approved containers for transporting fuel to the chainsaw.
- Refuel in a well-ventilated area (outdoors only).
- Dispense fuel at least 10 feet away from any sources of ignition when performing construction activities. No smoking during fuelling.
- Use a funnel or flexible hose when pouring fuel into the saw.
- Check fuel cap on the chainsaw to avoid leakage.
- Never attempt to fuel a running or HOT chainsaw.
Chainsaw control measures
- Clear away dirt, debris, small tree limbs and rocks from the saw chain path. Look for nails, spikes or other metal in the tree before cutting.
- Shut off the chainsaw or engage its chain brake when carrying the saw on rough or uneven terrain.
- Keep your hands on the chainsaw’s handles, and maintain secure footing while operating the saw.
- Proper personal protective equipment must be worn when operating the saw, which includes hand, foot, leg, eye, face, hearing and head protection.
- Do not wear loose-fitting clothing.
- Be careful that the trunk or tree limbs will not bind against the saw.
- Watch for branches under tension as they may spring out when cut.
- Gasoline-powered chain saws must be equipped with a protective device that minimizes kickback.
- Be cautious of saw kickback. To avoid kickback, do not saw with the tip. If equipped, keep tip guard in place.
