WORKPLACE HAZARDS
y
Slipping, tripping and falls are the main causes of injury
at the workplace. Warning against slippery surfaces
caused by the use of tools and also against the danger
of tripping on air utility lines or hydraulic hoses.
y
In unknown locations, movement should be performed
with care. There may exist hidden hazards such as
electrical wiring or other utility lines.
y
Tools for threaded tools are not intended for use in
potentially explosive environments and are generally not
insulated against contact with live electrical conduits.
y
The workplace must be checked for electrical cables,
gas pipes, etc., which could present a hazard as a result
of the tool being used.
HAZARDS CAUSED BY DUST AND FUMES
y
Dust and fumes created during the use of the tool
for threaded joints may result in illness (for example
malignant tumour illness, congenital disorders, asthma
and/or skin inflammation); the basic requirement is
the assessment of risks and implementation of suitable
measures for reducing these hazards.
y
Risk assessment should include the dust created during
the use of the tool and the potential of existing dama-
ging dust.
y
The exhaust must be setup in such a manner that the
damaging effects of dust in a dusty environment are
minimised.
y
If dust or fumes are being created, the priority must be
to reduce them at the point of their emission.
y
All integral main components or accessories for the
capture, exhaust or reduction of the amount of airborne
dust or fumes must be properly used and maintained in
accordance with the instructions of the manufacturer.
y
Respiratory protection must be used in accordance with
the instructions of the employer or as required by work-
place health and safety regulations.
HAZARDS RESULTING FROM NOISE
y
Exposure to high levels of noise may cause permanent,
incapacitating hearing loss and other problems such
as tinnitus (ringing, humming, whistling or roaring in
the ears). For these hazards, the basic requirement is
the assessment of risks and implementation of suitable
measures for managing these hazards.
y
Suitable risk reduction management methods may
include measures such as noise dampening materials
preventing the „ringing“ of workpieces.
y
Hearing protection must be used in accordance with
the instructions of the manufacturer and as required by
workplace health and safety regulations.
y
Tools for threaded joints must be used and maintained
as recommended in the user‘s manual to prevent unne-
cessarily increasing the noise level.
y
In the event that the tool is supplied together with
a damper, then an inspection must always be perfor-
med to ensure that it is functioning during the use of
the tool and in proper working order.
y
Consumables/sockets must be selected, maintained
and replaced as recommended in the user‘s manual to
prevent unnecessarily increasing the noise level.
HAZARDS RESULTING FROM VIBRATIONS
Operating instructions must provide information about
the hazards resulting from vibrations, which were not
eliminated during the design and construction of the
tool, and which persists as residual risks resulting from
vibrations. It must enable the employers to identify the
circumstances under which the users will most probably
be exposed to vibration related hazards. In the event that
the vibration emission value as defined by ISO 28927-2
does not represent a suitable level of vibration during the
assumed use (predictable incorrect forms of use) of the
tool, then additional information and/or warnings must
be issued enabling the assessment and management of
vibration related risks.
The recommended connection dimensions for spindles
and drive sockets help to reduce vibrations, see ISO/TS
21108.
y
Exposure to vibrations may result in incapacitating
damage to nerves and blood circulation in hands and
arms.
y
Hands must be kept at a sufficient distance from the
sockets for tightening the nuts.
HAZARDS RELATED TO GETTING CAUGHT
/ WINDING ON
y
In the event that loose clothing, personal jewellery,
necklaces, loose hair or gloves are not kept at a suffi-
cient distance from the tool or accessories, chocking,
scalping and/or lacerations may result.
y
Gloves may become caught in the rotating drive and
may result in injury or broken fingers.
y
The rotating drive socket or attachment can easily catch
gloves with a rubber surface coating or reinforced with
metal material.
y
Warning against wearing loose gloves that are too big
or gloves with cut or worn out material in the vicinity
of the fingers.
y
Warning against enclosing the drive, socket or drive
attachment with the free hand.
y
Hands must be kept at a sufficient distance from the
rotating drive.
HAZARDS DURING OPERATION
y
Using the tool may present a hazard to the hands of the
user, including compression, impact, cuts, grazes and
hazards from the effects of heat. Appropriate gloves
should be worn for hand protection.
y
The users and maintenance personnel must be physica-
lly strong enough to handle the size, weight and power
of the tool.
y
The tool must be held in the correct manner; the user
must be ready to handle normal as well as sudden
movements and have both hands available.
y
The user must maintain a balanced and safe stance.
y
In cases where an element for blocking reactionary
torque is required, it is recommended, if possible, to use
a support arm. If this is not possible, it is recommended
to use side handles on tools in the die configuration
and with a pistol grip handle. In the case of impact
wrenches with an angle configuration, supports are
recommended. In any case, it is recommended to utilize
elements for blocking reactionary torque on die tools
above 4 Nm, on pistol grip handle tools above 10 Nm
and on nut impact wrenches in angle configuration
above 60 Nm.
y
The control mechanism for starting and stopping must
be released in the event of a power outage.
y
Lubricants recommended by the manufacturer must be used.
y
Warning against finger compression on impact wren-
ches with an open key.
y
Warning against using the tool in confined areas and
warning against compression of the hand between the
tool and the workpiece, particularly when loosening.
HAZARDS ARISING FROM REPETITIVE
MOVEMENTS
y
When using the tool for threaded joints, the user may
be exposed to discomfort of hands, arms, shoulders,
neck and other parts of the body.
y
When using the tool for threaded joints, it is reco-
mmended that the user positions himself in a comforta-
ble and safe stance, and avoids inappropriate positions
or positions where he is not balanced. During longer
duration work tasks, the user should change position,
which may help to avoid discomfort and fatigue.
y
If the user starts suffering from symptoms such as
permanent or repetitive discomfort, pain, tremors,
tingling, desensitisation, burning feeling or stiffness,
then these warning symptoms should not be ignored.
The user should inform the employer and consult the
situation with a qualified healthcare professional.
HAZARDS ARISING FROM ACCESSORIES
y
The tool for threaded joints must be disconnect from
the air supply before tools or accessories are changed.
y
The user must not touch the sockets or accessories
during impact operation, as this increases the risk of
cuts, grazes or vibration-induced injuries.
y
Only the size and type of accessories and consumables
recommended by the manufacturer of the tool for
threaded joints may be used. Other types or sizes of
accessories or consumables must not be used.
y
Only sockets designed for impact wrenches of nominal
size and in good condition may be used because sockets
and accessories in poor condition or intended for manu-
al work may tear apart when used with impact drills
and eject a projectile.
