2. While using an assembly power tool for threaded fasteners, the operator should adopt a comfortable posture whilst maintaining secure
footing and avoiding awkward or off-balanced postures. The operator should change posture during extended tasks, which can help
avoid discomfort and fatigue.
3. If the operator experiences symptoms such as persistent or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning
sensations or stiffness, these warning signs should not be ignored. The operator should tell the employer and consult a qualified health
professional.
Safety precautions for accessory hazards
1. Disconnect the assembly power tool for threaded fasteners from the energy supply before changing the inserted tool or accessory.
2. Use only sizes and types of accessories and consumables that are recommended by the assembly power tool for threaded fasteners
manufacturer.
Safety precautions for workplace hazards
1. Slips, trips and falls are major causes of workplace injury. Be aware of slippery surfaces caused by the use of the tool and also of trip
hazards caused by the air line or hydraulic hose.
2. Proceed with care in unfamiliar surroundings. Hidden hazards, such as electricity or other utility lines, can exist.
3. The assembly power tool for threaded fasteners is not intended for use in potentially explosive atmospheres and is not insulated
against coming into contact with electric power.
4. Make sure there are no electrical cables, gas pipes, etc., that can cause a hazard if damaged by use of the tool.
Safety precautions for dust and fume hazards
1. Dust and fumes generated when using assembly power tools for threaded fasteners can cause ill health (for example, cancer, birth
defects, asthma and/or dermatitis); risk assessment and implementation of appropriate controls for these hazards are essential.
2. Risk assessment should include dust created by the use of the tool and the potential for disturbing existing dust.
3. Direct the exhaust so as to minimize disturbance of dust in a dust-filled environment.
4. Where dust or fumes are created, the priority shall be to control them at the point of emission.
5. All integral features or accessories for the collection, extraction or suppression of airborne dust or fumes should be correctly used and
maintained in accordance with the manufacturer's instructions.
6. Use respiratory protection in accordance with employer's instructions and as required by occupational health and safety regulations.
Safety precautions for noise hazards
1. Unprotected exposure to high noise levels can cause permanent, disabling, hearing loss and other problems, such as tinnitus (ringing,
buzzing, whistling or humming in the ears).
2. Risk assessment and implementation of appropriate controls for these hazards are essential.
3. Appropriate controls to reduce the risk may include actions such as damping materials to prevent workpieces from “ringing”.
4. Use hearing protection in accordance with employer's instructions and as required by occupational health and safety regulations.
5. Operate and maintain the assembly power tool for threaded fasteners as recommended in the instruction handbook, to prevent an
unnecessary increase in noise levels.
6. If the assembly power tool for threaded fasteners has a silencer, always ensure it is in place and in good working order when the
assembly power tool for threaded fasteners is operating.
7. Select, maintain and replace the consumable/inserted tool as recommended in the instruction handbook, to prevent an unnecessary
increase in noise.
Safety precautions for vibration hazards
1. Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms.
2. Wear warm clothing when working in cold conditions and keep your hands warm and dry.
3. If you experience numbness, tingling, pain or whitening of the skin in your fingers or hands, stop using the assembly power tool for
threaded fasteners, tell your employer and consult a physician.
4. Operate and maintain the assembly power tool for threaded fasteners as recommended in the instruction handbook, to prevent an
unnecessary increase in vibration levels.
5. Select, maintain and replace the consumable/inserted tool as recommended in the instruction handbook, to prevent an unnecessary
increase in vibration levels.
6. Sleeve fittings should be used where practicable.
7. Support the weight of the tool in a stand, tensioner or balancer, if possible.
8. Hold the tool with a light but safe grip, taking account of the required hand reaction forces, because the risk from vibration is generally
greater when the grip force is higher.
Additional safety instructions for pneumatic power tools
1. Always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not in use, before changing accessories
or when making repairs.
2. Never direct air at yourself or anyone else.
3. Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fittings.
4. Cold air shall be directed away from the hands.
5. Whenever universal twist couplings (claw couplings) are used, lock pins shall be installed and whipcheck safety cables shall be used to
safeguard against possible hose-to-tool and hose-and-hose connection failure.
6. Do not exceed the maximum air pressure stated on the tool.
7. For torque-control and continuous-rotation tools, the air pressure has a safety critical effect on performance. Therefore, requirements
for length and diameter of the hose shall be specified.
8. Never carry an air tool by the hose.
