DO NOT WEAR: • Tennis shoes (wear thick soled leather shoes,
which provide some protection for the feet) • Sandals • Shorts, or cutoffs, • Tank tops, muscle shirts, etc. • Neckties, loose or torn clothing • Rings, watches, bracelets, or other jewelry that
could get caught in moving machinery. • Loose clothing or long sleeves (machines can
easily grab loose clothing in rotating parts)
Wear clothing appropriate for the shop
Don’t be “Hair Brained”Wear your hair suitable for the
shop. You may protect long hair by:
1. Tying it neatly behind your head 2. Wearing a hair net
Things like: Long hair, loose clothing, and jewelry can become easily caught in rotating machinery commonly found on the shop floor
General shop Safety Sense• Do not operate any machine unless authorized to do so by an
Instructor or under an instructor's supervision. • Do not set up or operate any machinery unless an instructor is
in the shop.• Use the proper tool for the job. Many cuts in the shop occur
when a wrench slips and a hand hits a sharp cutting tool. • Check tools before use to assure they are safe to use.• Aisles should be clear at all times to avoid tripping or other
accidents. • Keep the floor free of oil, grease, or any other type of liquid.
Clean up spilled liquids immediately; they are slipping hazards.
• Put tools away when not in use. • Place all scrap pieces in the correct containers. • Never handle chips with your hands or fingers. Chips are
extremely sharp • Use a brush to remove chips -- not hands, fingers, or rags.
General shop safety tips continued
• Never use your gloves or use rags to clean the work piece or any part of a machine that is running. Rotating tools or parts can grab gloves and rags and pull you into the machine.
• Never use compressed air to clean any machine.
• Do not run in the shop; there should be no "fooling around"
• Get first aid immediately for any injury.
• Be careful around a person operating machinery; you may bump him/her by accident or startle them and cause an accident
• Make all adjustments with the machine off and locked out.
• Do not use machines without proper guards in place.
Special eye protection for welding or cutting is required

Lathe safety • Wear safety glasses.• Material being machined
generates heat and can become hot!
• Use a brush to remove metal chips.
• Machining can produce a long spiral shaving, these are extremely hot and sharp do not touch!
