Chainsaw Safety (Non-Forestry)

Chainsaws on construction sites are used for cutting timber, clearing vegetation, and occasional demolition tasks.
Chainsaw injuries are among the most severe in construction: deep lacerations, amputations, and fatal wounds.
Kickback occurs when the chain tip contacts an object, throwing the saw violently upward toward the operator.
All chainsaw operators must be trained and hold a relevant certificate of competence for the tasks performed.
Full chainsaw PPE includes helmet with visor and ear defenders, chainsaw trousers, gloves, and safety boots.
Chainsaw trousers contain fibres that clog the chain on contact, stopping it before it reaches the skin.
The chain brake must be engaged when carrying the saw and whenever it is not actively cutting.
Refuelling must be done with the engine stopped and cooled to prevent fuel ignition on hot components.
PUWER 1998 requires that chainsaws are maintained, inspected, and used only by competent trained persons.
A first aid kit with large wound dressings and a tourniquet must be immediately available during chainsaw use.

Severe laceration	Chainsaw cuts penetrate deeply, severing arteries, tendons, and bone in fractions of a second.
Kickback danger	Kickback throws the running saw toward the operator head and body faster than human reaction time.
Legal requirement	PUWER 1998 requires trained, competent operators and appropriate PPE for all chainsaw operations.

Do

Don't

Wear full chainsaw PPE: helmet, visor, ear defenders, trousers, gloves, and boots.
Check the chain brake, chain tension, and bar condition before each use.
Engage the chain brake when carrying the saw and between cuts.
Maintain a clear work area and escape route before starting any cut.
Keep a first aid kit with large dressings and a tourniquet within immediate reach.
Refuel with the engine stopped and the saw cooled away from ignition sources.
Hold the saw firmly with both hands at all times during cutting.
Ensure you hold a valid certificate of competence for the tasks being performed.
Work with a buddy present who can summon help in an emergency.
Inspect the chain for damage, sharpness, and correct tension before each use.

DON'T operate a chainsaw without full chainsaw PPE including protective trousers.
DON'T cut with the tip of the bar; this is the kickback danger zone.
DON'T use a chainsaw above shoulder height from ground level.
DON'T operate a chainsaw without holding a valid competence certificate.
DON'T carry a running chainsaw with the chain brake disengaged.
DON'T refuel while the engine is running or the saw is still hot.
DON'T use a chainsaw with a dull, loose, or damaged chain.
DON'T work alone with a chainsaw; always have someone nearby.
DON'T drop-start a chainsaw; use the ground or leg-lock starting method.
DON'T cut into ground, nails, or wire which damages the chain instantly.
