assessed for each use. The risks to others should also be assessed at this time. Ensure that the workpiece is securely fixed.
Check that the means of protection from ejection of fastener and/or stem is in place and is operative. Warn against the possible
forcible ejection of installation mandrels from the front of the assembly power tool for non-threaded mechanical fasteners.
Operating hazards
Use of the tool can expose the operator's hands to hazards, including crushing, impacts, cuts and abrasions and heat. Wear
suitable gloves to protect hands. Operators and maintenance personnel shall be physically able to handle the bulk, weight and
power of the tool. Hold the tool correctly; be ready to counteract normal or sudden movements and have both hands available.
Maintain a balanced body position and secure footing. Release the start-and-stop device in the case of an interruption of the
energy supply. Use only lubricants recommended by the manufacturer. Avoid unsuitable postures as it is likely for these positions
not to allow counteracting of normal or unexpected movement of the tool. If the assembly power tool for non-threaded mechanical
fasteners is fixed to a suspension device, make sure that the fixation is secure. Beware of the risk of crushing or pinching if nose
equipment is not fitted.
Repetitive motions hazards
When using an assembly power tool for non-threaded mechanical fasteners, the operator can experience discomfort in the hands,
arms, shoulders, neck or other parts of the body. While using an assembly power tool for non-threaded mechanical fasteners, the
operator should adopt a comfortable posture whilst maintaining a secure footing and avoiding awkward or off-balance postures.
The operator should change posture during extended tasks; this can help avoid discomfort and fatigue. 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.
Accessory hazards
Disconnect the assembly power tool for non-threaded mechanical fasteners from the energy supply before changing the inserted
tool or accessory. Use only sizes and types of accessories and consumables that are recommended by the manufacturer of as-
sembly power tools for non-threaded mechanical fasteners; do not use other types or sizes of accessories or consumables.
Workplace hazards
Slips, trips and falls are major causes of workplace injury. Be aware of slippery surfaces caused by use of the tool and also of trip
hazards caused by the air line or hydraulic hose. Proceed with care in unfamiliar surroundings. There can be hidden hazards,
such as electricity or other utility lines. The assembly power tool for non-threaded mechanical fasteners is not intended for use
in potentially explosive atmospheres and is not insulated against contact with electric power. Ensure that there are no electrical
cables, gas pipes, etc., which can cause a hazard if damaged by use of the tool.
Noise hazards
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). Therefore, risk assessment and the implementation of appropriate controls for these hazards
are essential. Appropriate controls to reduce the risk may include actions such as damping materials to prevent workpieces from
"ringing". Use hearing protection in accordance with employer's instructions and as required by occupational health and safety
regulations. Operate and maintain the assembly power tool for non-threaded mechanical fasteners as recommended in the in-
struction handbook, to prevent an unnecessary increase in the noise level. Select, maintain and replace the consumable/inserted
tool as recommended in the instruction handbook, to prevent an unnecessary increase in noise. If the power tool has a silencer,
always ensure that it is in place and in good working order when the power tool is being operated.
Vibration hazards
Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms. Wear warm clothing
when working in cold conditions and keep your hands warm and dry. If you experience numbness, tingling, pain or whitening of
the skin in your fingers or hands, stop using the assembly power tool for non-threaded mechanical fasteners, tell your employer
and consult a physician. Support the weight of the tool in a stand, tensioner or balancer, because a lighter grip can then be used
to support the tool.
Additional safety instructions for pneumatic power tools
Air under pressure can cause severe injury:
- 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;
- never direct air at yourself or anyone else.
Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fittings. Cold air shall be directed away
from hands. 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 or hose-to-hose connection failure. Do not exceed the maximum
air pressure stated on the tool. Never carry an air tool by the hose.
