Safety is no accident !
• As you view these slides, you should realize that a major part of shop safety is based upon common sense and thinking ahead. It is an accepted fact that forethought and the elimination of carelessness can avoid most shop accidents.
•This unit is designed to familiarize students with common shop hazards. Its goal is to prevent injuries to the people who use the shop facilities.

Always wear SAFETY GLASSES in the shop.

DO NOT WEAR: • 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 • Long sleeves (Machines can easily grab
loose clothing in rotating parts.)
Wear clothing appropriate for the job.

Don’t be “hair-brained”!
Wear your hair suitable for the trade. You may protect long hair
by:
1. Tying it neatly behind your head 2. Wearing a hair net .

General Safety Tips• 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.• 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.

General Safety Tips (continued)
• Never wear 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 or startle him or her and cause an accident.
• Make all adjustments with the machine off and locked out.
• Do not use machines without proper guards in place.

Cutting fluid can cause slippery floor conditions.
Use a material to soak up the liquid (speedy dry, cat-litter, sawdust) when needed.
