Mortising and Tenoning Machines: Hazard Identification
Risk management strategy for mortising and tenoning machines which identifies hazards that can expose a worker to the risk of injury, and records the measures used to remove or reduce the level of risk.
The following table is a risk management strategy for mortising and tenoning machines.
Risk management strategy
Hazard identification
Risk factors
Risk control measures
1
Cutting hazard created by the cutters
Exposed section of the chain cutter or chisel
Premature start-up of the machine
Operator exposing hands in feeding process
Chain cutter or chisel for mortising machine is enclosed within adjustable guarding
Automatic guard fitted and correctly adjusted for tenoning machine
Lock out tag out (LOTO) protocol implemented and maintained
Clear workspace is maintained around the machine
2
Object being thrown by the machine/cutter
Timber work piece is lifted off and thrown from the work table during cutting
Ensure the timber piece has been securely clamped into place before starting the machine
3
Manual handling lifting timber piece to work table
Variation in material size, shape and weight
Long or awkward timber pieces being handled on and off machine
Store raw materials at appropriate height to avoid the need for bending or twisting
Use a trolley to assist in moving timber piece on and off machine
Use a second person to guide a long or large piece from the machine
4
Slips trips and falls
Obstructed or cluttered work area around the machine
Slippery and uneven floor surface
Maintain a clear work space in and around the machine
Provide non-slip floor surfaces that give a firm foothold
5
Noise hazard created by machinery operation
Cutting action of chain or chisel, and different woods creating varying noise levels when being processed
Various machines in the area operating simultaneously
Local acoustic dampening to reduce noise levels
Hearing protectors used by operator and all people accessing the workshop
Warning signs erected in workshop
6
Crushing from transmission drive
Access to internal area of machine
Fixed guarding encloses all transmission and associated moving parts
LOTO protocol implemented and maintained
7
Airborne contaminants
(eg dust and vapours)
High speed cutting action
Ventilation extraction system poorly maintained
Provide and maintain local exhaust ventilation
Wear protective personal equipment (PPE) such as face masks
Regularly vacuum dust and sawdust
Note: Do not use compressed air to remove dust from skin or clothing
