Mechanical and PDM Laboratory Safety Procedures

These guidelines address equipment and procedures that will mainly be used by those utilizing Mechanical and PDM laboratories.
The environment in which you are being taught within the Kennedy and Keller Building labs closely resembles that which is found in factories and other industrial facilities. Consequently, personal safety equipment and dress standards of what is found in industry will be enforced.
There is a risk of injury when wearing inappropriate clothing and footwear, such as shoes that do not cover the entire foot, and long legged baggy pants, long baggy shirt sleeves, certain styles of jewelry, and loose clothing or hair are strongly discouraged. Signs posted at laboratory doors may specifically prohibit these or additional personal hazard items.
1. DO NOT run your machine or piece of equipment until you understand the operation of,  been qualified to operate by School of Engineering personnel, and signed a verification of understanding for that specific piece of equipment.

2. Safety glasses MUST be worn anytime you are within 10 ft. of flying particles. It doesn’t matter if the material is plastic, wood, or metal. Should you provide your own safety glasses, they must meet ANSI standard Z87.1, which includes having side shields.

3. DO NOT operate any power or machine tool while under the influence of drugs, alcohol, or any medication.

4. KEEP all power and machine tool guards in place and in working order. Loose objects can become flying projectiles.

5. TAKE OUT all chuck keys and adjusting wrenches from power and machine tools before turning the power on.

6. KEEP your work area clean. Cluttered areas and benches invite accidents.

7. DO NOT wear gloves when operating power or machine tools. They are easily caught in moving parts. Take them off before you turn on a machine.

8. WEAR only a canvas or leather type shoe that covers the ENTIRE foot.

9. DO NOT use power tools in damp or wet locations.

10. DO NOT force your power or machine cutting tool. It will do the job better and be safer at the rate for which it was designed.

11. USE the correct tool. Don’t force a tool or attachment to do a job for which it was not designed.

12. SECURE your work. Use clamps or a properly fastened vise to hold work when practical. It’s much safer than using your hand and frees both hands to operate the tool.

13. PROTECT your hands. Always allow a spindle or blade to stop completely before you clear away chips or oil. USE a brush or chip scraper.

14. DO NOT ever reach around a safeguard.

15. DO NOT get trapped. Avoid placing your fingers, hands, arms, legs in power and machine tool pinch points.

16. DO NOT overreach. Keep proper footing and balance at all times.

17. USE your powers of observation when using any power or machine tool.

18. ALWAYS feed your work into a blade or cutter against the direction of rotation of the blade or cutter only.

19. ALWAYS inspect tools and blades for damage. Dull and damaged tools break easily and create more work. Keep tool overhangs short, i.e. long lever vs. short lever.

20. NEVER look directly at a welding arc ray. Large amounts of ultraviolet light rays are produced and can cause eye pain and temporary blindness.

21. NEVER leave a power or machine tool running unattended. If you step away even for a minute, TURN POWER OFF.

22. ROBOTS in motion can be dangerous, especially during training, programming, and testing.

23. RETURN tools to their proper place and in good working order. Inform the safety supervisor of any necessary replacement or repairs.

24. SHOULD you become angry, rushed, or tired, STOP WORKING! Return to your job when you are better prepared to work safely.
