shop. You may protect long hair by:

1. Tying it neatly behind your head 2. Wearing a hair net

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.
