SafetyRequirementsforAbrasiveSandingMachines
Abrasive sanding can be hazardous to operators and
bystanders. Sanding sparks, chips and dust particles
thrown off by the sanding disc can cause serious
injury if contacted or inhaled. To avoid such injuries
you must comply with the following safety
requirements:
1. Always wear pr otect ive ey ewear w hen oper ati ng
machinery. Eye wear shall be impact resistant,
safety glasses with side shields which comply
with ANSI Z87.1. Use of eye wear which does not
comply with ANSI Z87.1 specifications could
result in severe injury from the breakage of the
eye protecti o n.
2. Wear leather safety gloves, arm guards, leather
aprons and safety shoes.
3. A dust collection system is recommended. The
operator should also wear a dust mask at all
times.
4. Additional precautions may be necessary for
sanding materials which are flammable or have
other hazardous properties. You should always
consult the m anufactur er of such materials for
instructions on sanding and handling.
5. Do not forc e or jam the workpiece int o the
sanding disc.
6. Before sanding, always allow the motor to come
up to operating speed, then check the sanding
disc for wobble, run-out, or any unbalanced
condition. If the disc is not operating accurately
and smoothly, immediately stop the motor and
make repairs before attempting any sanding
operations.
7. Abrasive discs must be stored in a controlled
environment . Relative humidity should be 35% to
50% and the temperature should be between 60°
and 80° Fahrenheit. Failure to do so could cause
premature dis c f ailure.
8. Examine the face of the sanding disc carefully.
Excessive sanding that wears down to the
backing material can tear the disc. Never use a
disc which shows backing, nicks or cuts on the
surface or edge, or damage due to creasing or
poor handling.
9. When install i ng a new di sc, be c ert ai n th e dis c i s
accurately centered on the drive wheel. Failure to
do so could cause a serious unbalanced
condition.
10. A lw ay s pr esent t he wo rk pi ec e to th e wh eel wh il e
resting the wor kpiec e firm ly on t he tabl e. Fai lure
to do so could result in damage to the workpiece
or throwing of t h e workpiece off t h e wheel.
11. Safety shoes which comply with ANSI Z41.1
should be worn.
12. Personal hearing protection such as ear plugs or
ear muffs should be used to protect against the
effect of nois e exposure.
