consumables that are recommended by the assembly
power tool for threaded fasteners manufacturer;
do not use other types or sizes of accessories and
consumables.
■
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
■
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.
■
Proceed with care in unfamiliar surroundings. Hidden
hazards, such as electricity or other utility lines, can
exist.
■
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.
■
Make sure there are no electrical cables, gas pipes,
etc., that can cause a hazard if damaged by use of
the tool.
DUST AND FUME HAZARDS
■
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.
■
Risk assessment should include dust created by the
use of the tool and the potential for disturbing existing
dust.
■
Direct the exhaust so as to minimize disturbance of
dust in a dust-filled environment.
■
Where dust or fumes are created, the priority shall be
to control them at the point of emission.
■
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.
■
Use respiratory protection in accordance with
employer’s instructions and as required by
occupational health and safety regulations.
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, a risk assessment and
implementation of appropriate controls for these
hazards are essential.
■
Appropriate controls to reduce the risk may include
actions such as damping materials to prevent work
pieces 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 threaded fasteners as recommended in the
instructions handbook, to prevent an unnecessary
increase in noise levels.
■
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.
■
Select, maintain and replace the consumable/inserted
tool as recommended in the instructions handbook, to
prevent an unnecessary increase in noise.
VIBRATION HAZARDS
The information for use shall draw attention to vibration
hazards that have not been eliminated by design and
construction and remain as residual vibration risks. It
shall enable employers to identify the circumstances in
which the operator is likely to be at risk from vibration
exposure. If the vibration emission value obtained using
ISO 28927-2 does not adequately represent the vibration
emission in the intended uses (and foreseeable misuses)
of the machine, additional information shall be supplied
to enable the risks arising from vibration to be assessed
and managed.
For recommended interface dimensions for spindles and
drive adapters to help reduce vibrations, see ISO/TS
21108.
■
Exposure to vibration can cause disabling damage to
the nerves and blood supply of the hands and arms.
■
Keep the hands away from the nutrunner sockets.
■
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 threaded fasteners, tell your
employer and consult a physician.
■
Operate and maintain the assembly power tool
for threaded fasteners as recommended in the
instructions handbook, to prevent an unnecessary
increase in vibration levels.
■
Do not use worn or ill-fitting sockets or extensions, as
this is likely to cause a substantial increase in vibration.
■
Select, maintain and replace the consumable/inserted
tool as recommended in the instructions handbook, to
prevent an unnecessary increase in vibration levels.
■
Sleeve fittings should be used where practicable.
■
Support the weight of the tool in a stand, tensioner or
balancer, if possible.
■
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.
