Safety requirements for abrasive
grinding machines
Abrasive grinding can be hazardous to operators
and bystanders. Grinding sparks, chips and dust
particles thrown off by the grinding disc or belt can
cause serious injury by contact or inhalation. To
avoid such injuries you must comply with the
following safety requirements:
1. Always wear protective eyewear when
operating machinery. Eye wear shall be impact
resistant, protective safety glasses with side
shields which comply with ANSI Z87.1.
2. Wear leather safety gloves, arm guards, leather
aprons and safety shoes.
3. A dust collection system is recommended,
Operator shall also wear a dust mask at all
times. See Figure B, below.
4. Additional precautions may be necessary for
grinding materials which are flammable or have
other hazardous properties. You should always
consult the manufacturer of such materials for
instructions on grinding and handling.
5. Do not force or jamb the workpiece into the
grinding disc/belt.
6. Before grinding, always allow the motor to come
up to operating speed, then check the grinding
disc for wobble, runout, or any unbalanced
condition. If the disc is not operating accurately
and smoothly, immediately stop the motor and
make repairs before attempting any grinding
operations.
7. Abrasives must be stored in a controlled
environment area. Relative humidity should be
35% to 50% and the temperature should be
between 60 and 80 degrees Fahrenheit.
Failure to do so could cause premature
abrasive failure.
8. Examine the face of the grinding disc/belt
carefully. Excessive grinding which wears down
to the backing material can tear the abrasive.
9. Never use an abrasive which shows backing,
nicks or cuts on the surface or edge or damage
due to creasing or poor handling.
10. Always present the workpiece to the wheel
while resting the workpiece firmly on the table.
Failure to do so could result in damage to the
workpiece or throwing of the workpiece off the
wheel.
11. Safety shoes which comply with ANSI Z41.1
shall be worn. See Figure C.
12. Personal hearing protection such as ear plugs
or ear muffs shall be used to protect against the
effect of noise exposure. See Figure D.
Familiarize yourself with the following safety notices used in this manual:
This means that if precautions are
not heeded, it may result in minor injury and/or
possible machine damage.
This means that if precautions are
not heeded, it may result in serious, or possibly even
fatal, injury.

WARNING:
Some dust, fumes and gases
created by power sanding, sawing, grinding,
drilling, welding and other construction activities
contain chemicals known to the State of
California to cause cancer and birth defects or
other reproductive harm. Some examples of
these chemicals are:
lead from lead based paint
crystalline silica from bricks, cement and
other masonry products
arsenic and chromium from chemically
treated lumber
Your risk of exposure varies, depending on how
often you do this type of work. To reduce your
exposure to these chemicals, work in a well-
ventilated area and work with approved safety
equipment, such as dust masks that are
specifically designed to filter out microscopic
particles. For more information go to
