Wear clothing appropriate for the job. 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 your hair suitable for the trade. You may protect long hair by: Don’t be “hair-brained”! 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.
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. General Safety Tips (continued)
Cutting fluid can cause slippery floor conditions. Use a material to soak up the liquid (speedy dry, cat-litter, sawdust) when needed.
Safety Glasses • All persons must wear safety glasses in the shop area. • If you wear prescription eye glasses, they must be covered by an approved safety glass.
Be aware! Cutting metal pieces can generate heat; gloves may be needed.
