- Be sure that all machines have effective and
properly working guards and covers, and that they are always in place
when machines are operating.
- Replace guards immediately after any repairs.
- Do not attempt to oil, clean, adjust, or repair
any machine while it is running. Stop the machine and lock the power
switch in the "OFF" position.
- Do not operate any machine unless authorized to
do so by the instructor or under the instructor's supervision.
- Do not set up or operate machinery when an
instructor is not in the shop.
- Even after the power is off, do not leave the
machine until it has stopped running. Someone else may not notice that
it is still in motion and be injured. Do not leave a machine until it
has come to a complete stop.
- Do not try to stop the machine with your hands or
body.
- Check tools before use to assure they are safe to
use.
- Always see that work and cutting tools on any
machine are clamped securely before starting to work.
- All set-screws should be of the flush or recessed
type. If they are not, move with caution when near them. Projecting
set-screws are very dangerous because they may catch on sleeves or
clothing.
- Only one person should operate the machine or
switches.
- Do not lean against the machine (s).
- Concentrate on the work and do not talk
unnecessarily while operating the machine.
- Do not talk to others when they are operating a
machine. A distraction may lead to an injury.
- Do not walk behind people operating a machine;
you may bump them by accident or startle them and cause an accident.
- Always remove gloves before turning on or
operating any machine. If material is rough or sharp and gloves must be
worn, place or handle material with the machine turned off.
- Do not leave tools or work on the table of a
machine even if the machine is not running. Tools or work may fall off
and cause toe or foot injury.
- Use a brush to remove short, discontinuous types
of chips--not hands, fingers, or rags.
- Use a pair of pliers to remove chips, especially
the long, stringy type.
- Never handle chips with your hands or fingers.
Chips are extremely sharp and can easily cause cuts.
- Never use compressed air to clean any machine.
- Never use compressed air to clean your clothes or
yourself.
- If using compressed air to clean a part, point
the air hose down and away from yourself and other persons.
- Never wear gloves or use rags to clean the
workpiece or any part of a machine that is running. Rotating tools or
parts can grab gloves and rags and pull you into the machine.
- Stop the machine tool to make speed and feed
changes that require the shifting of a gear lever.
- Always use correct speeds and feeds. A broken
tool becomes a hazard and can cause great personal injury.
- Make sure the machine is OFF before making any
adjustments or repairs.
