9.3 Machinery Hazards
Pages in this chapter (7 of 10)
Cylinder mower
The main hazards and risks are:
- parts of the body coming into contact with the mower blades
- being hit by objects thrown by the rotating blades
- burns from touching a muffler or cylinder that has not had time to cool
- fires caused by refuelling while the engine is still hot
- noise-induced hearing loss after long-term exposure
- being unaware of surroundings, including running into bystanders when backing up because the operator did not look behind
- rollovers that may pin the operator or bring them into contact with the blades
The main control measures are:
- read the mower's instruction manual before use
- keep the mower in good working order with sharp blades, and use only a mower that has protection over hot and sharp parts
- pick up potential flying objects, such as stones, toys and debris, before mowing
- wear goggles, hearing protection, gloves and long trousers, and always wear sturdy, closed-toe shoes
- do not remove safety devices or guards on switches
- before clearing grass or debris, follow the manufacturer's isolation method, including battery, electrical or ignition sources as applicable, and wait for all movement to stop. Control stored or spring energy where present. A stick or broom handle is not permission to clear a running or merely switched-off mechanism
- never lift a mower by the bottom for transport, because the blades can cut fingers even if they are not moving. When it is moved or picked up, the mower should be turned off with the spark plug disconnected and unplugged
- never cut grass when it is wet or damp
- do not pull a mower backwards or ride it in reverse unless necessary
Strimmer or brush cutter
The main hazards and risks are:
- brush cutters can fling up objects such as sticks and stones at high speed, which can injure the operator and anyone close by
- the rotating blade or cutting cord can cause serious injury if it touches the face, hands, legs or feet
- the noise can lead to hearing loss
- vibration can cause permanent damage to the hands
- fuel spillage, hot sparks or smoking can be a fire hazard
The main control measures are:
- operate the unit only on stable ground, keeping good balance and secure footing to avoid slips and falls
- do not operate the unit without the proper shield deflector in place
- inspect the area where the equipment will be used and remove all visible stones, sticks, wires and other debris
- do not cut near hard objects when using rigid blades
- keep hands and feet away from moving parts and cutting blades
- keep a firm grip on the handles and work slowly, to minimise kickout and the risk of hitting hidden objects
- use the attachments only as they were designed to be operated
- operate the equipment only with adequate visibility and light
Chainsaw
The main hazards and risks of the petrol-driven chainsaw are:
- cuts on contact with the moving chain
- entanglement with the moving chain
- drawing in at the nip point between the chain and the casing
- puncture by ejected parts, especially broken chain fragments
- burns from the hot exhaust system
- hearing loss from high noise
- vibration into the hands
- fire and explosion from petrol
- ergonomic problems from handling
- health hazards from dust, fumes and lubricating oils
- carbon monoxide poisoning
The main control measures are:
- use chainsaws only after being trained to use them properly and safely
- follow the owner's manual carefully
- review the health and safety legislation that applies before operating a chainsaw
- operate, adjust and maintain saws according to the manufacturer's directions
- operate the chainsaw only in well-ventilated areas
- wear PPE and suitable clothing
- have all required supplies and equipment with you before you start
- be aware of your surroundings: weather, terrain, wildlife, buildings, power lines, vehicles and other people
- never walk around with a chainsaw in operating mode. Always switch off the power source
- do not try to cut anything other than wood with a chainsaw
- do not operate a chainsaw if you are tired, because concentration and a secure grip will not be at their best
- make sure the chain brake works
- keep oil and fuel off the handles
- always switch the chainsaw off before setting it down
