General Shop Safety

  1. Safety is the top priority in this shop. No tool or job is more important than you.
  2. WEAR PROPER EYE PROTECTION AT ALL TIMES. Safety glasses with side shields are the minimum requirement. Goggles or face shields are to be used when grinding. Properly tinted goggles or face shields are to be used when welding. DO NOT WEAR CONTACT LENSES WHEN WELDING. Lenses can become fused to the cornea of the eye, which may cause blindness.
  3. Wear proper clothing when you come to work in the shop. Wear socks and shoes that enclose the feet and long pants to protect your feet and legs from hot sparks and sharp metal chips. Wear long sleeve shirts buttoned high to the neck when welding to protect you from sparks and welding arc light which is actinic light (excessive ultraviolet) and will cause severe burns to the skin. Rolls sleeves up or wear short sleeve shirts, remove rings, watches, and necklaces, put long hair up under a hat, and do not wear loose or dangly clothing when working around moving machine parts. Shirts must cover up to the neck to protect you from hot metal chips. Highly flammable clothing is to be avoided.
  4. Keep your work area clean and clear of clutter.
  5. Understand the operation of the machine and the procedure to be performed. DO NOT HESITATE TO ASK QUESTIONS.
  6. All machine guards and safety devices must be installed and in good operating condition before starting or using any machine or tool. If you are not sure, STOP and ASK the instructor.
  7. Use the proper tool for the job. Keep the tools sharp. Keep tool over hang as short as possible and use proper speeds and feeds so as to prevent tool breakage and chatter.
  8. IF AN EMERGENCY HAPPENS, THROW OFF THE ELECTRICAL SWITCH.
  9. Carefully plan and check each job before starting to work. Give your full attention to the job. Understand the relative motions of the various parts of the machine, the tool, and the work in order to prevent collisions.
  10. NEVER leave a machine unattended while it is running. Do not lean on the machine.
  11. Always have adequate light for the job.
  12. ALWAYS REPORT ANY INJURY!!!
  13. ALWAYS STOP THE MACHINE BEFORE taking measurements, adjusting, repairing, cleaning, or oiling.
  14. NEVER USE YOUR FINGERS TO REMOVE METAL CHIPS. Chips are sharp. Use a brush. Do not use air pressure. Airborne chips are eye hazards and air pressure can force chips under the machine slides causing premature wear to the machine.
  15. Report or correct any hazards you find in the shop. Report any malfunctioning equipment.
  16. Before touching metals check for heat. Metal working processes generate heat. Beware of sharp edges. Carry materials safely so as to not injure other people.
  17. Get help when lifting heavy or awkward objects.
  18. If you need help or are unsure of yourself get help from the instructor.
  19. Cutting tools must NOT be in contact with the work piece when starting the machine.
  20. Keep hands away from the starting switch or clutch lever when taking measurements, adjusting the work, or changing cutting tools. Be sure no one else is near them.
  21. REMOVE CHUCK KEYS AND WRENCHES FROM MOVING MACHINE PARTS. DO NOT LET GO OF THEM UNTIL THEY ARE STOWED IN THEIR PROPER PLACE. They will become dangerous projectiles if left on the moving machine part. Secure the work and the tools properly to the machine.
  22. On Bench grinders, the tool rest and top guard must be adjusted to within 1/8 inch (3mm) of the grinding wheel. When grinding, the tool rest is used to support your hand. This gives you better control of the operation. Only grind ferrous metals on an aluminum oxide wheel. Other materials will load up the wheel creating heat causing the wheel to burst. For the other materials use silicone carbide wheels.

Lathe Safety and Setup Procedures

  1. WEAR SAFETY GLASSES, roll up sleeves, and remove jewelry from hands and neck, secure hair to keep it from getting wound up in revolving machinery.
  2. Before operating this machine understand the function of all electrical and mechanical controls on the machine.
  3. Move the carriage to provide ample space at headstock to properly mount the chuck, faceplate, or collet. Always provide ample space when loading and unloading materials and attachments especially around sharp cutting tools.
  4. Mount the work in the chuck, collet, or between centers. When using a chuck, REMOVE THE CHUCK WRENCH IMMEDIATELY and STOW IT IN ITS PROPER PLACE. Never let go of this wrench until it is stowed. If it is left in the chuck it will become a dangerous projectile when the spindle is turned on.
  5. Mount the tool bit into the tool holder with minimal projection to maximize rigidity and prevent chatter.( Tool projection about the width of your thumb.)
  6. Mount the tool holder onto the compound slide at the left hand side. This position will help to prevent the compound slide from running into the chuck or spindle attachments. AS OPERATOR YOU MUST PREVENT COLLISIONS.
  7. Cutting tools mounted on the compound slide are to be set with their top cutting edge on the center line of the work as viewed from the front side of the lathe.
  8. Bring the tool over near but not touching the start point of the operation to be performed. Revolve the spindle by hand to check for binding or any other clearance problems. Be sure that there will be no clearance problems throughout the proposed travel.
  9. Use proper feed and speeds for the type of material and the procedure. The instructor can help you determine this until you have more experience.
  10. When mounting tools in the tailstock IMMEDIATELY REMOVE CHUCK KEY and STOW IT IN ITS PROPER PLACE. Never let go of the key until it is stowed.
  11. When using a file on work revolving on the lathe always file left handed to keep you from slipping into the chuck. NEVER USE A FILE WITHOUT A HANDLE.
  12. Never handle chips with your fingers. USE A BRUSH TO REMOVE CHIPS. Stop the machine to do this.
  13. Stop the machine before taking measurements.
  14. When mounting work between centers IMMEDIATELY REMOVE ANY WRENCH USED TO TIGHTEN THE LATHE DOG. THIS IS ANOTHER DANGEROUS PROJECTILE HAZZARD.
  15. When turning between centers do not cut completely through the work with a cutoff tool.
  16. THINK ABOUT THE RELATIVE MOTIONS and THE POTENTIAL HAZZARDS before performing any operation.
  17. Keep yourself safe. ASK THE INSTRUCTOR when you are unsure of the operation. The only dumb question is the one not asked.
  18. If something does not seem right don’t start the machine. If an emergency happens shut off the switch and/or get away from the machine and get the instructor.
  19. Only one person to work at a machine at any time.
  20. YOU ARE MORE IMPORTANT THAN ANY PIECE OF WORK OR MACHINE.
