Eye protection shall be worn at all times when operating
power equipment and tools.
Report all equipment defects immediately. Do not use
unsafe equipment until it is repaired.
When disconnecting equipment, pull on the plug, not the
cord. Whenever the use of electrical extension cords is required, keep them
clean, dry, and free from kinks. Protect them from oil, hot or sharp surfaces,
and chemicals. Exterior cords should not be extended across aisles, through
water, doors, or into areas where they are apt to be damaged.
Use equipment properly; do not overload the motor by
forcing cutting tools into the work.
Do not leave power tools unattended while in operation.
Portable electric circular and band saws shall not be
used unless the guard mechanism is functioning properly.
Oversized drill bits shall not be ground to fit smaller
electric drills.
Long hair and loose clothes must be restrained in a manner
that will not allow them to be caught in machines.
Woodworking Machines
Workers shall make sure that guards or other protective
devices for woodworking machines are in place and properly adjusted before
starting work. Workers shall not operate woodworking machines with cracked
or defective blades or cutters.
Workers shall not install blades or cutters unless they
are designed to run at the speed of the machine on which they are to be mounted.
Operators of woodworking machines SHALL NOT WEAR GLOVES
unless the point of operation is completely guarded and contact with the blade,
or moving parts, is not possible.
A push stick or block shall be used for any operation
which requires the fingers to be within 2 inches of the blade. Dust or wood
scrap should not be removed from the danger area by hand. Always use a brush.
Saw operators should not stand in line with material
to be cut.
The operator’s position should be kept clear of
sawdust, blocks, etc., at all times.
Power saws shall not be stopped by thrusting a block
of wood against the cutting edge or side of the blade.
Kickbacks on table saws are extremely hazardous. The
following conditions may lead to injury:
Improper alignment of the rip fence.
Failure to use a spreader.
Crosscutting narrow stock while using the rip fence
as a stop.
Attempting to rip or crosscut stock which is too
large to control.
Cutting warped, wet or twisted grain lumber which
binds the blade.
Failure to use anti-kickback dogs.
Attempting to rip stock that does not have at least
one straight edge for use against the fence.
Failure to lock the fence securely in place.
Using a dull or improperly set blade.
Using a blade that is out of round, or improperly
balanced.
Grinding Machines
Grinding wheels and wire brushes shall not be operated
in excess of the speed recommended by the manufacturer. Check the recommended
rpm against that of the shaft or motor before mounting a new wheel. Check
all grinding wheels for chips and cracks before use.
Face shields, safety glasses, or chipper’s goggles
shall be worn at all times when grinding or using a wire brush.
Gloves shall not be worn while grinding, nor will cloth
be used to hold work pieces.
Do not operate grinding machines unless metal wheel hoods
are in place. Do not apply work too quickly to a cold wheel.
Tool rests shall be secured at all times and adjusted
to within 1/8 inch of the wheel. Top wheel guards shall be adjusted to within
1/8 inch of the top of the wheel.
Disc grinder tables shall be adjusted to within 1/8 inch
of the disc.
When a grinder is first turned on, do not stand in line
with the grinding wheel. If any wobble or vibration is noticed, the machine
must be turned off and repaired.
Except where specifically designed, one should not grind
on the sides of the grinding wheel.
Do not grind wood, aluminum, copper, or other soft materials
on wheels designed for steel and iron.
Metal Lathes
Chip guards should be used in operations that could endanger
the operator or others nearby.
Chip breakers shall be used whenever practical. Tool
ways must be kept clear and clean.
Tools should not be set or adjusted while the lathe is
in operation. Tools and chucks must be checked for defects before use.
Brushes or chip pullers shall be used for removing chips.
Operators shall not use their hands, or compressed air in excess of 30 psi,
to remove chips.
Heavy chucks, face plates, or other heavy equipment should
never be handled without proper lifting equipment.
Tools or other equipment shall not be stored on top of
the head stock.
Rotating stock extending into aisles should be marked
with a warning device (yellow tape, rag, tag) or contained by physical barrier.
Magnesium or similar metals shall not be machined unless
appropriate fire protection is provided.
Do not stop lathe with tool bit in the cut, or with feed
clutch engaged. Hand pressure should not be used to stop free spinning chucks.
Metal Cutting Band Saws
Before starting an operation, be sure the machine is
set for the recommended speed, feed, and blade type for the material to be
cut.
A complete face shield shall be worn when blades are
electrically welded on the machine.
The portion of the blade between the upper wheel and
the saw table should be completely enclosed except for the point at which
the cut is made.
Inspect and adjust the table and blade guide to be sure
that small parts cannot jam between the table and moving blade.
The length of the exposed blade should not be more than
3/8 inch greater than the thickness of the stock being cut.
Use pliers, tongs, jigs, or other hold-down devices when
sawing small parts that could jam between the blade and saw guide.
Warn personnel or install barriers during sawing or welding
operations that throw hot sparks onto nearby work stations.
Metal Planers, Shapers, drilling and Boring Machines
Always use brushes or chip pullers to clean the work
area. Operators shall not use their hands or compressed air in excess of 30
psi to remove chips.
Always clamp the work securely before starting the cut.
Do not measure the job while the machine is in operation.
Always remove the stroke-change screw handle before starting
the shaper.
Do not place heavy parts or tools on the machine without
the use of approved lifting equipment.
Only soft metal or plastic hammers should be used when
setting up jobs on a drill press or boring mill.
Adjustable wrenches should not be used on the machine
parts or equipment. Properly sized box or open-end wrenches should be used.
Do not operate drill presses with dull tools.
Never make adjustments on the chuck when the machine
is in motion.
Boring mill operators should never attempt to make measurements
near the tool, reach across the table, or adjust the work while the spindle
is turning.
When deep holes are being drilled beyond the flutes of
the drill, the drill should be withdrawn frequently to keep it free of chips.
Stop the machine before attempting to clear work that
has been jammed.
Power Presses and Forming Equipment
Do not operate power punch presses without “point
of operation guarding.” Do not remove or modify guards.
Power presses shall not be operated in the continuous
tripping cycle unless the point of operation is guarded on all sides by approved
barrier guards.
Safety tongs shall be used whenever it is necessary to
reach into the point of operation of any machine.
Explosive Actuated Tools
Explosive actuated tool operators must be trained and
certified for this work.
Always wear safety goggles to avoid the possibility of
flying chips, etc.
Never, under any conditions, attempt to discharge a stud
or pin into free flight.
Use only the appropriate boosters, studs, and pins designed
for the tool.
Never drive a stud or pin into extremely hard surfaces
such as glazed tile, glazed brick, glass, tool steel, etc. Such surfaces may
cause a ricochet.
Do not drive fasteners closer than 3 inches from the
edge of concrete, brick, or other like materials.
Do not drive fasteners closer than 1/2 inch from the
edge of steel.
In the event of misfire the tool is to be held in operating
position for a minimum of 30 seconds before disassembly.
Handling Chemicals
Do not wash hands in cleaning solvents. Absorption of
these liquids through the skin can cause serious illness.
Do not handle chemicals of any type unless you are aware
of the potential skin and inhalation hazards. Consult the appropriate MSDS.
Wear appropriate skin, face, eye, and hand protection
when moving or handling bulk chemicals.
Always wear chemical resistant gloves, aprons, and complete
eye protection when handling corrosive chemicals. If chemicals contact skin,
wash with large amounts of water immediately.
Do not open chemical containers which have been stored
in the sun unless proper care is taken. Many chemicals will build up pressure
in the container when exposed to heat.
Clean up small chemical spills immediately if you can
do it safely; otherwise, notify supervisor.
