4.0 Procedure
4.1 General Requirements
- Always wear safety glasses or goggles (and also a face shield, if the impact hazard is high (see EHS 301, Personal Protective Equipment).
- Wear hearing protection that is suitable for the level and frequency of the noise you are exposed to in the woodworking area (see EHS 203, Hearing Conservation Program).
- Use gloves to protect hands from splinters when handling wood, but do not wear them near rotating blades and other machinery parts where the gloves can
become entangled. - Make sure all machine guards are in position, are in good working condition, and guard the machine adequately before operating any equipment or machine
(see ESH 407, Machine Guarding). - Check and adjust all other safety devices.
- Make sure the equipment is properly grounded before use.
- Check that keys and adjusting wrenches are removed from the machine before turning on the power.
- Inspect stock for nails or other materials before cutting, planing, routing, or carrying out similar activities.
- Make sure that all machines have start and stop buttons within easy and convenient reach of an operator.
· Start buttons should be protected so that accidental contact will not start the machine.
· A collar around the button one-eighth (1/8) to one-fourth (1/4) inch above the button is recommended.
- Ensure that all cutting tools and blades are clean, sharp, and in good working order so that they will cut freely, not forcefully.
- Turn the power OFF and unplug the power cord (or lock out the power source) before inspecting, changing, cleaning, adjusting, or repairing a blade or a
machine (see EHS 403, Lockout/Tagout).
Also, turn the power OFF when discussing the work.
- Keep hands out of the line of the cutting blade.
a. Push sticks or push blocks must be used when operating standard woodworking machinery, including table saws, band saws, radial arm saws,
jointer/planers, and shapers.
b. Push sticks protect the hand while allowing good control of the stock as it is pushed through the cutting head or blade.
c. Push blocks for jointer/planers must be constructed for two-handed positioning.
d. Push blocks must:
- Be rigid
- Enable the operator to protect both hands
· Allow the operator to exert a firm and steady pressure on the work piece.
13. Clamp down and secure all work pieces when drilling or milling.
- Use good lighting so that the workpiece, cutting blades, and machine controls can be seen clearly.
Position or shade lighting sources so they do not shine in the operator’s eyes or cause any glare and reflections.
- Ensure that the floor space around the equipment is sufficient to enable you to machine the size of work piece being processed safely, without bumping
into other workers or equipment. - Woodworking machines must be fitted with efficient and well-maintained local exhaust ventilation systems to remove sawdust or chips that are produced.
- Electric power cords must be above head level or on the floor in such a way that they are not tripping hazards.
- Keep work area free of clutter, clean, well swept, and well lit.
- Spills must be cleaned up immediately.
- Floor areas should be level and non-slip.
· Good housekeeping practices and workplace design will reduce the number of injuries and accidents from slips, trips, and falls.
- Do not wear loose clothing, work gloves, neckties, rings, bracelets, or other jewelry that can become entangled with moving parts.
- Avoid awkward operations and hand positions.
A sudden slip could cause your hand to move into the cutting tool or blade.
- Do not remove sawdust or cuttings from the cutting head by hand.
Use a stick or brush only when the machine has stopped moving.
- Do not use compressed air to remove sawdust, turnings, etc. from machines or clothing.
- Do not leave machines running unattended (unless they are designed and intended to be operated while unattended).
Do not leave a machine until the power is turned OFF and the machine comes to a complete stop.
- Do not try to free a stalled blade before turning the power OFF.
- Do not distract or startle an operator while he/she is using woodworking equipment.
26. Do not operate electric tools near flammable liquids or in gaseous or explosive atmospheres. Sparks might ignite fumes.
27. Do not use electric tools in damp or wet locations.
- Horseplay is prohibited. It can lead to injuries.
4.2 Band Saws
- Wear safety glasses.
- Make sure all guards are in place and properly adjusted.
Ensure all band wheels are enclosed.
- For saws with adjustable cutting tables, ensure that the under-table blade guard is installed and in place.
- Adjust blade guard height to about one-eighth (1/8) inch above the top of the material being cut.
- Ensure the blade is tracking correctly and runs freely in and against the upper and lower guide rollers.
- Ensure the blade is under proper tension. A band saw equipped with automatic tension control is desirable.
- Use band saw blades that are sharp, properly set, and otherwise suitable for the job:
· Right tooth pitch
· Tooth form
· Blade width.
- Hold stock firmly and flat on the table to prevent the stock from turning and drawing your fingers against the blade.
Keep hands braced against the table.
- When cutting small pieces of wood, use a push stick when
· Removing cut pieces from between the fence and saw blade
· Hands are close to the blade. Keep hands on either side of the blade, not in line with the cutting line and the blade.
- Make release (relief) cuts before tight curves when doing intricate scroll-type work.
- Keep the floor around a band saw clean and free of obstructions or clutter.
- Keep the machine properly oiled and serviced.
- Ensure adequate lighting at the machine table in order to see the work.
- Do not use excessive force when pushing the wood into the blade.
- Do not back the stock away from the blade while the saw is in motion, if the work piece binds or pinches on the blade.
- Do not stop a band saw by thrusting stock against the cutting edge, or the side of a blade, immediately after the power has been shut OFF.
- Do not remove sawdust or cuttings from the table by hand or with compressed air. Use a stick or brush.
- Do not leave a saw running unattended. Turn OFF the power and make sure the machine has stopped running before leaving the area.
4.3 Jointers and Planers
- Wear safety glasses.
- Allow only experienced and trained personnel to operate jointers and planers.
- Use only sharp, balanced, and joined knives.
- Replace old square cutting heads with round heads; they are much safer.
- Ensure start and stop buttons are within easy and convenient reach of the operator.
- Make sure the swing guard pushes beside the stock as it passes over the cutting heads and returns against the fence after the stock is removed.
- Remove all wrenches and tools used in the set-up from the table.
- Provide a minimum clearance of at least three (3) feet greater than the length of the longest stock being worked.
- Construct hold-down push blocks to perform beveling and surface operations.
- Use hold-down (double-handed) push blocks to keep hands well away from the cutting head.
- Maintain an adequate amount of downward and forward force with push blocks. The knife blades on a revolving cutting head can pull the stock from an
operator’s hands. - Do not leave the machine running unattended. Shut OFF the power and make sure that the cutting head has stopped revolving.
- Do not make cuts deeper than one-sixteenth (1/16) inch in one pass.
- Do not join (edge) stock of pieces less than twelve (12) inches long, three-fourths (3/4) inch wide, and less than one-fourth (1/4) inch thick.
- Do not surface stock less than twelve (12) inches long, three-fourths (3/4) inch wide, or more than six (6) inches wide and less than five-eighths
(5/8) inch thick.
16. Do not pass hands over the cutters.
- Do not remove dust or particles of wood from a table by hand or with compressed air. Use a stick or brush.
4.4 Mitre Saws
- Wear safety glasses.
- Attach the saw firmly on a workbench or other rigid frame and operate saw at waist height.
a. The saw can also be taken to remote locations by mounting it on a piece of plywood one-half (1/2) inch or thicker.
b. This must be clamped, with large “C” clamps, to a waist-high work surface on the job site.
- Keep one hand on the trigger switch and handle, and use the other hand to hold the stock against the fence.
- Keep hands out of the path of the blade.
- Keep guards in place and in working order.
- Remove adjusting keys and wrenches.
- Use a crosscut or combination blade.
- Ensure that the blade rotates in the correct direction.
- Ensure that the blade and arbor collars are secure and clean. Recessed sides of collars must be against blade.
- Keep blade tight, clean, sharp, and properly set, so that it cuts freely and easily.
- Allow motor to reach full speed before cutting.
- Follow instructions for lubricating and changing accessories.
- Keep the work area clean. Cluttered areas and benches invite accidents.
- Keep the work area well lit.
- Reduce the risk of unintentional startup. Make sure saw switch is in OFF position before plugging in.
16. Unplug tools before servicing and when not in use.
- Check for damage. Repair or replace damaged parts.
- Keep motor air slots clean and free of chips.
- Do not operate the saw on ground.
- Do not cut pieces smaller than eight (8) inches in length.
- Do not cut “free-hand.” The stock should lie solidly on the table against the fence.
- Do not reach around or behind the saw blade.
- Do not take your hand away from the trigger switch and handle, until the blade is fully covered by the lower blade guard.
- Do not overreach. Keep proper footing and balance at all times.
- Do not force the saw. The saw cuts better and more safely at the rate for which it was designed.
- Do not leave the saw until it has stopped completely. Turn the power OFF and unplug the saw.
4.5 Radial Arm Saws
- Wear safety glasses.
- Feed stock against the direction of the blade. (The blade rotates downward when viewed by the operator.)
- Only use saw blades rated at or above the speed of the saw arbor. (An arbor is the attachment from motor to blade.)
- Use only the accessories designed for that specific saw and application.
- Ensure the guard consists of two parts:
· Upper hood type that covers arbor
· Lower guard that rides on the stock, adjusting automatically to the thickness being cut.
- Stand on the handle side when cross cutting. Pull the cutting head with the hand nearest the handle and maneuver the stock with the other hand.
- Make sure the hand holding the stock is never in line with the blade.
- Return the cutting head completely to the back of the saw table after each cut. The saw should be designed so that the blade will not move forward
under its own weight or if the machine is vibrating. - When ripping, make sure that the overall length of the saw table (both infeed and outfeed) is twice the length of the longest pieces of lumber.
- When ripping, make sure that the stock is fed against the direction of the blade (from the side by which the saw blade rotates upward toward the
operator).
· The blade should extend slightly into the table.
· The motor head must be locked at the correct height and angle.
- Clamp stock to the table on one side of the saw blade, when making mitre, bevel, or compound mitre cuts. Clamping prevents the wood from sliding along
the fence during the cut. - Turn OFF the saw when making any adjustments or changes in the set up.
- Make measurements by placing the wood to be cut against the stop gauge. When measuring with a tape measure or ruler is necessary, turn OFF the saw
until the measuring is complete. - Do not use radial arm saws for ripping, unless the spreader (riving knife) and anti-kickback devices are provided and properly adjusted.
- Do not take your hand away from the operating handle, unless the cutting head is behind the fence.
- Do not remove the stock from a saw table, until the blade has been returned to its “resting” position at the back of the saw table. Use a stick or
brush to remove scrap from the saw table. - Do not cut “free-hand.” Use the back guide, fence, or other device to keep the workpiece from moving.
- Do not use cracked or dull blades.
- Do not leave a running saw unattended. Leave only after the saw has been turned OFF and it has come to a complete stop.
4.6 Sanders
- Wear safety glasses.
- Keep hands away from the abrasive surface.
- Hold small or thin pieces of stock in a jig or holding device, to prevent injuries to the fingers or hands.
- Inspect abrasive belts before using them. Replace belts worn, frayed, or excessively worn in spots.
- Sand on the downward side of a disc sander so that the wood is driven onto the table by the machine’s rotation.
- Enclose all drums, disk, or belt-sanding machines with an exhaust dust hood that covers all portions of the machine, except the portion designed for
the work feed. - Adjust work rests on all manually fed sanders to provide minimum clearance between the belt and the rest. The work rest must be secured properly.
- Install abrasive belts that are the same width as the pulley drum.
- Adjust abrasive belt tension to keep the belt running the same speed as pulley-drum when the wood is in contact with the belt.
- Guard feed rollers to allow boards to pass, but keep operators’ fingers and arms out.
- Install guards to prevent contacts at:
· In-running nip points
· Power transmission
· Feed roll parts
· The unused portion of the abrasion belt on the operator’s side of the machine.
12. Do not sand small or thin hand-held work pieces.
- Do not wear loose clothing or jewelry while using revolving power tools.
· Tie back long hair or wear appropriate hair protection.
· These measures will prevent hair, clothing, or jewelry (like dangling neck chains) from being entangled and pulled by sander belts and pulleys that are
in motion.
- Do not operate sanders, without the exhaust system operating.
- Do not operate sanders, unless adequately guarded.
- Do not operate sanders, unless the work rest is properly adjusted.
4.7 Shapers
- Wear safety glasses.
- Use the cutter (and spindle speed/RPM) suited for the job.
- Use sharp cutters only and keep them clean.
- Remove all wrenches and tools used in the set-up from the table.
- Check moving parts of the shaper periodically, such as belts and pulleys, for signs of wear; also check the spindle for burrs or for excessive runout.
- Make sure all guards are in proper position.
7. Before operating check:
a. That the spindle is square with the shaper table
b. That the spindle top and knives are correctly adjusted and securely fastened
c. That the spindle is free before turning on the power.
- Use jig fixtures, holders, and hold-down push blocks.
· Fasten the work securely in a jig.
· When a table guide pin is used, make sure it is adjusted and will not slip.
9. Cut with the grain, rather than against it.
- Remove all other blades when one blade is removed from the shaper spindle. This will prevent the other blades from being hurled from the spindle if the
machine is started. - Turn OFF power.
- Lock out a machine when doing set-ups or any other operation on or about the spindle.
- Shape only one piece of stock at a time. Use extra care in machining stock that contains cross grains or knots. These might pull the operator’s hands
into the knives or might cause kickbacks. - Shape stock only if longer than ten (10) inches
- Support long pieces of wood with extension tables or roller supports.
- Do not leave a shaper machine running. Make sure that the power is shut OFF and that the cutter head has stopped revolving before leaving the area.
- Do not rest your hands near the edge of the stock being cut.
- Do not tamper with the guards or make them inoperative in any way.
- Do not back up the stock.
· Check to see that the direction of rotation is as expected.
· Always feed against rotation of the cutter.
- Do not make deep cuts or feed the stock too rapidly.
- Do not distract or startle an operator during a shaping operation.
- Do not remove sawdust or cuttings around knives by hand or with compressed air. Use a stick or brush.
- Do not clear the table while the cutter is rotating.
- Do not accumulate stock or finished work on the table.
- Do not stand in line with the stock being fed.
4.8 Table Saws
- Wear safety glasses.
- Pay particular attention to the manufacturer’s instructions on reducing the risk of kickback (when the wood can be violently thrown back toward the
operator). - Choose proper blades for the type of work being done.
- Keep blades clean, sharp, and properly set, so that they will cut freely, without having to force the work piece against the blade.
- Use the guards provided with the saw or ones designed for use with the saw that you are using. Keep them in place and in good working condition.
- Use a guard high enough to cover the part of the blade, which projects above the stock, and wide enough to cover the blade when it is tilted. The blade
height must be set so it does not extend more than one-eighth (1/8) inch above the height of the piece being cut. - Ensure that the fence is locked into position after the desired width has been set.
- Hold the work piece firmly down on the table and against the fence when pushing the wood through.
- Ensure that adequate support is used to hold a work piece.
· Use extension tables or roller supports at the side or back for larger pieces.
· If an assistant is at the back (outfeed) end of the saw, an extension table must be in place so the back edge is about four (4) feet from the saw blade.
· The assistant must wait for the work piece to reach the edge of the extension table and must not reach toward the saw blade.
- Feed stock into the blade against the direction of its rotation.
- Move the rip fence out of the way when cross cutting. Never use it as a cut-off gauge.
- Use a push stick when ripping narrow or short stock
· When the fence is set less than about six (6) inches from the blade
· When the piece is less than twelve (12) inches long
· When the last twelve (12) inches of a longer piece is being cut, refer to ripping applications in the manufacturer’s instruction manual.
- Keep hands out of the line of a saw blade.
- Use guard with a spreader (riving knife) and anti-kickback fingers for all ripping or cross cutting operations.
- Keep the body and face to one side of the saw blade, out of the line of a possible kickback.
- Provide adequate support to the rear and sides of a saw table for wide or long stock.
- Be careful when waxing, cleaning, or servicing the table. Shut OFF and unplug (or lock out) a saw before doing any work on the saw.
- Keep area clean and clutter-free. Operate machines in a non-congested, well-lit area.
- Use the proper sawdust exhaust systems as required by operation.
- Do not reach around or over moving blades.
- Do not feed the work piece faster than the saw can accept.
- Do not leave a saw running unattended. Turn OFF the power and make sure the machine has stopped running before leaving the area.
4.9 Wood Turning Lathes
- Wear safety glasses and face shield to protect yourself from flying chips.
- Work in well-lighted area.
- Before the lathe is turned on, ensure that all clamps and fittings are secure and that the work piece is free to turn.
- Use stock free of defects.
- Hold tools firmly with both hands and against the tool rest.
- Hold the stock securely on the faceplate or between the centers.
- Use only furnished or approved tools.
- Use sharp, well-maintained chisels and gouges.
- Select a speed that is appropriate for the job. Operate the lathe at a low speed and use a moderate cut depth to prevent splinters from flying out
during roughing operations. The actual speed of the lathe depends upon:
· Type of wood
· Diameter of stock
· Nature of work being performed
· Type of tool used.
- Adjust tool rests so that they are parallel and as close as possible to the stock. They must also be set high enough so that tools will cut into the
wood slightly above the center of the work being turned. - Remove the tool rest when sanding or polishing.
- Hold the sandpaper in your fingers and press lightly against a small area at the top of the rotating shaft when hard sanding. This will keep the
sandpaper from catching and pulling your hand around the stock. - To make a faceplate turning, one hand steadies the tip of the chisel, which holds the edge against the tool rest, while the other hand guides the tool.
Keep the tip of the chisel held higher than the handle. - Do not wear gloves, loose clothing, rings, or jewelry around the neck that can hang outside one’s clothing.
· Clothing should be comfortable, but not so loose that it can catch on the machine, or become entangled with any rotating parts or the wood being turned.
· Shirts must be tucked in.
· Long hair must be tied back.
- Do not leave a running lathe unattended. Leave only after the lathe has been turned OFF and it has come to a complete stop.
- Do not use makeshift tools.
- Do not use stock containing:
- Checks
- Splits
- Cracks
- Knots.
