cold and dampness, diet, smoking and work practices are
thought to contribute to the conditions. Any user suffering
prolonged symptoms of tingling, numbness, blanching of
fingers, clumsiness or weakened grip, nocturnal pain in the
hand, or any other disorder of the shoulders, arms, wrists, or
fingers is advised to consult a physician. If it is determined
that the symptoms are job related or aggravated by move-
ments and postures dictated by the job design, it may be
necessary for the employer to take steps to prevent further
occurrences. These steps might include, but are not limited
to, repositioning the workpiece or redesigning the worksta-
tion, reassigning workers to other jobs, rotating jobs, chang-
ing work pace, and/or changing the type of tool used so as to
minimize stress on the operator. Some tasks may require
more than one type of tool to obtain the optimum operator/
tool/task relationship.
• Tasks should be performed in such a manner
that the wrists are maintained in a neutral
position, which is not flexed, hyperextended,
or turned side to side.
• Stressful postures should be avoided. Select
a tool appropriate for the job and work
location.
Work gloves with vibration reducing liners and wrist supports
are available from some manufacturers of industrial work
gloves. Tool wraps and grips are also available from a
numberofdifferentmanufacturers.Thesegloves,wraps,and
wrist supports are designed to reduce and moderate the
effects of extended vibration exposure and repetitive wrist
trauma.Since theyvarywidely indesign, material,thickness,
vibration reduction, and wrist support qualities, it is recom-
mended that the glove, tool wrap, or wrist support manufac-
turer be consulted for items designed for your specific appli-
cation. Proper fit of gloves is important. Improperly fitted
gloves may restrict blood flow to the fingers and can
substantially reduce grip strength.

if the throttle is accidently engaged. Use of a self-relieving
valve within reach of the user of the tool is highly recom-
mended.
Do not operate or trigger any percussion tool unless the
chisel, scaling tool, rivet set, or other implement is in the tool
andincontactwiththeworkpieceorworksurface.Neverpoint
any percussion tool in the direction of another person or
yourself, or deliberately eject a chisel. Failure to do so can
cause serious injury and/or damage the tool.
Chisel or rivet set retainers are recommended and furnished
asstandard equipment.Periodic inspection of the retainer
forwearordamageisrecommendedsincethesedevices
can receive heavy abuse, particularly if the tool is run off
the workpiece. Damaged retainers are dangerous, and
can allow the ejection of a chisel or other implement.
They must be replaced as necessary. Only use safety
retainer type chisels, as shown in the operating instruc-
tions and service manual. Also, it is good safety practice to
erect suitable barriers to protect persons in surrounding or
lower work areas from possible ejected tools.
Some individuals
may be suscep-
tible to disorders
of the hands and
arms when per-
forming tasks
consisting of
highly repetitive
motions and/or
exposure to ex-
tended vibration.
Cumulative
trauma disorders such as carpal tunnel syndrome and ten-
donitis may be caused or aggravated by repetitious, forceful
exertions of the hands and arms. Vibration may contribute to
a condition called Raynaud’s Syndrome. These disorders
developgraduallyover periods of weeks,months, and years.
It is presently unknown to what extent exposure to vibrations
or repetitive motions may contribute to the disorders. Heredi-
tary factors, vasculatory or circulatory problems, exposure to
Safety Recommendations
Repetitive work motions and/or vibration
may cause injury to hands and arms.
Use minimum hand grip force.
Keep body and hands warm and dry.
Avoid anything that inhibits blood circulation.
Avoid continuous vibration exposure.
Keep wrists straight.
Avoid repeated bending of wrists and hands.
