especially when unscrewing .
Repetitive Motions Hazards
a) When using a power tool the operator can experience discomfort in the hands, arms, shoulders,
neck, or other parts of the body .
b) 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 .
c) 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
a) Disconnect the assembly power tool for threaded fasteners from the energy supply before fitting
or changing the inserted tool or accessory .
b) Do not touch sockets or accessories during impacting, as this increases the risk of cuts, burns or
vibration Injuries .
c) Use only sizes and types of accessories and consumables that are recommended by the assembly
power tool for threaded fasteners manufacturer .
Air Impact Butterfly Wrench
d) Use only impact-wrench-rated sockets in good condition, as poor condition or hand sockets and
accessories used with impact wrenches can shatter and become a projectile .
Workplace Hazards
a) 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 .

use of the tool .
Dust and Fume Hazards
a) 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 .
b) Risk assessment should include dust created by the use of the tool and the potential for
disturbing existing dust .
c) Direct the exhaust so as to minimise disturbance of dust in a dust-filled environment.
d) Where dust or fumes are created, the priority should be to control them at the point of emission .
e) 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 manufacturers
instructions .
f) Use respiratory protection in accordance with employer's instructions and as required by
occupational health and safety regulations .
Noise Hazards
a) 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 implementation of appropriate controls for these hazards are essential .
b) Appropriate controls to reduce the risk can include actions such as damping materials to prevent
workpieces from 'ringing' .
c) Use hearing protection in accordance with employer's instructions and as required by
occupational health and safety regulations .
d) Operate and maintain the assembly power tool for threaded fasteners as recommended in the
