Robotic Workshop Safety Tips

  1. 1. 2007 Woodside/ Carlmont High School Robotics Safety Procedures, Shop and Tool Safety By Bob Steinfeld
  2. 2. My Background <ul><li>Taught Industrial Arts at Sequoia High School for 20 years. Electronics, and Metals. </li></ul><ul><li>Participated as a parent mentor for FIRST Robotics in 2003 and 2004 at Woodside. </li></ul><ul><li>Participated as a parent mentor for FIRST Robotics at Los Gatos High School for 3 years. </li></ul><ul><li>Attended the FIRST Nationals in 2005 and 2007. </li></ul><ul><li>2005 - 2007 Coach and mentor for a FIRST Lego League team in Los Gatos - The WildCats. </li></ul>
  3. 3. Part 1 Being Physically and Mentally Ready To Work In The Shop <ul><li>Safety procedures actually start before you come to work in the shop. </li></ul><ul><li>How do you feel? Are you tired? </li></ul><ul><ul><li>When you are tired, have pain or are stressed out it is difficult to concentrate and accidents can occur. </li></ul></ul><ul><li>Are you taking medications? </li></ul><ul><li>Do you have the correct clothes? </li></ul><ul><li>Do you have the correct safety equipment? </li></ul><ul><li>When was the last time you had a Tetanus shot? </li></ul>

Medications, Drugs, & Alcohol <ul><li>Some over the counter medication can make you tired or drowsy? </li></ul><ul><ul><li>Acetaminophen, Ibuprofen, Sudafed… </li></ul></ul><ul><li>Prescription medications? What are the side effects. </li></ul><ul><li>Cough medicines. Cough medicines may contain alcohol. </li></ul><ul><li>Medications, alcohol, and drugs can impair your judgment, make you sleepy and can cause injuries. </li></ul><ul><li>If you have taken medication that can cause problems choose not to work with tools. </li></ul><ul><li>Injuries to you or others can occur by your poor judgment in taking drugs or medications. </li></ul>
  5. 6. Focusing On Your Work and Knowing about the Tools <ul><li>Fooling around, joking, running, pushing, or wandering away from the group without permission are all safety violations. </li></ul><ul><li>Do not use any tool until you have been checked out on the operation of the tool. </li></ul><ul><li>Tools must be used for the purposes in which they are intended. Uses other than the intended purpose are a safety violation. </li></ul><ul><ul><li>Can you give some examples? </li></ul></ul><ul><li>A clean workspace leads to a safe workspace. </li></ul><ul><li>Provide people space to do their work. </li></ul><ul><li>Your careless work can lead to injuring yourself or other people. </li></ul>
  6. 7. Clothing <ul><li>Frayed clothes can catch fire or get caught in rotating machinery. No frayed clothes. </li></ul><ul><li>Loose fitting clothes can get caught in rotating machinery, No loose fitting clothes. </li></ul><ul><li>Avoid have anything but your shirt around your neck? No neckties, neck chains and necklaces. </li></ul><ul><li>Working with machine tools, hand tools, and metal greater than 1 pound require that your feet are protected. No open shoes and you must wear sox. </li></ul>
  7. 8. Safety Equipment <ul><li>Safety glasses or a face shield are required while working on the robot or while making parts. You must be able to see out of the safety glasses? Wear eye protection . </li></ul><ul><li>For sanding, grinding and noisy cutting processes? Use ear protection for noisy processes . </li></ul><ul><li>If there are chemicals, paint, or dust; protect your lungs with the proper mask. Wear a mask for painting and dusty processes. </li></ul><ul><li>When working around arc welding protect your skin and eyes from the ultraviolet light produced by the welding arc? Wear a long sleeve shirt, and the correct shade of eye protection if you look at the arc . </li></ul>
  8. 10. Part 2 Shop Work - Safety <ul><li>Cutting different materials </li></ul><ul><li>Wood, aluminum, steel, copper, plastic, fiberglass, and glass epoxy (printed circuit board) materials. </li></ul><ul><li>Using hand tools </li></ul><ul><li>Screwdrivers, hammers, punches, wrenches, chisels. </li></ul><ul><li>Using hand held power tools </li></ul><ul><li>Skill saw, reciprocating saw, electric drill, electric screwdriver, hand grinder, or hand sander. </li></ul><ul><li>Using stationary power tools </li></ul><ul><li>Band saw, Sander, Grinder, drill press, milling machine, lathe </li></ul>
  9. 11. The Working Environment Light and Space <ul><li>Safe working areas have good lighting and adequate space to work. </li></ul>
  10. 12. How Materials Cut <ul><li>Soft materials such as wood, plastic, and aluminum cut fast. The cutting tools also turn faster for these softer materials. Fast cutting materials are more dangerous because cutting happens quickly. </li></ul><ul><li>Hard materials like steel, and stainless steel cut slow. The cutting tools travel slower but generate heat faster. Hard materials get hot and the chips produced are hot. </li></ul><ul><li>The toolbit speeds for aluminum and steel are very different. </li></ul><ul><ul><li>Aluminum fast, steel slow, but this also depends on the size of the cutting tool and the size of material being cut. </li></ul></ul><ul><li>Typically, you can’t cut a material that is harder than the cutting tool . </li></ul>
  11. 13. Cutting Tools <ul><li>Cutting tools are very hard but also are very brittle . </li></ul><ul><ul><li>Small pieces of the toolbit can break off if not used properly. </li></ul></ul><ul><ul><li>Cutting tools must be kept sharp. Dull tools create extra heat and can cause the tool to break. </li></ul></ul>
  12. 14. Hand Tool Safety Rules <ul><li>Tools must be used for their intended purpose. </li></ul><ul><li>Tools should be inspected before use. </li></ul><ul><ul><li>Screwdrivers - are not pry bars, or chisels. </li></ul></ul><ul><ul><li>Hammers- the faces are hardened and can break off if hammering on a hard surface. </li></ul></ul><ul><ul><li>Wire cutters- are designed to cut certain size wires made of copper wire, don’t overload the tool by trying to cut steel. </li></ul></ul><ul><ul><li>Pliers - don’t pinch your fingers and don’t overload the tool. </li></ul></ul><ul><ul><li>Files - are very brittle and are not pry bars. Files should be used with a handle because the tang is sharp. </li></ul></ul><ul><ul><li>Wrenches- should not be used with extension bars to increase leverage. This can cause the wrench or socket to break. </li></ul></ul>
  13. 18. Hand Held Power Tool Safety Rules <ul><li>Electric Drills </li></ul><ul><ul><li>The tool should be inspected before use. Remove the chuck key before starting the drill. </li></ul></ul><ul><ul><li>Inspect the drill bit to make sure it is sharp. If you don’t know ask . </li></ul></ul><ul><ul><li>Drill bit size affects speed it should turn. Also make sure the drill bit will turn in the correct direction. </li></ul></ul><ul><ul><li>Safety glasses must be over your eyes. </li></ul></ul><ul><ul><li>Keep your fingers and clothes at least 3 inches away from the drill bit when it’s turning. </li></ul></ul><ul><ul><li>Use the correct speed, and pressure for the material you are drilling. If you don’t know ask for help . </li></ul></ul><ul><ul><li>Clamp the workpiece so it doesn’t move during drilling. </li></ul></ul><ul><ul><li>Stay centered over the hole being drilled. </li></ul></ul><ul><ul><li>If the drill has a cord keep the cord away from the rotating drill bit. </li></ul></ul>
