Lab Safety Guidelines for Robotics Team Members

1. Beach Cities RoboticsTeam 294 General Lab Safety Presentation

2. Why Talk Safety? • We emerge from the season with all limbs securely intact • Avoid causing bodily harm to yourself or another individual • Follow the mission and principles of FIRST

3. General Lab Safety Rules Attire • Wear closed toe shoes (no sandals or flip-flops) • Tie long hair back (there are hair ties in the office) • No loose or baggy clothing • Keep shoulders and arms covered (no tank tops) • Use safety glasses!

4. General Lab Safety Rules Behavior • No running or horseplay in lab • Keep all food in the kitchen area • When you finish using something, put it back in the proper place. Good housekeeping avoids injuries! • When using tools, make sure you are working with a mentor or older student who has been trained on any tools you are using. Attitude • Safety is everyone’s responsibility! • Use common sense! • When in doubt, ASK!

5. Review! • Where should you eat your food in lab? • What do you do when you finish using a tool? • What should you wear to lab?

6. Rules in Specific Lab Areas Computer and Design Area Programming Area Electronics Area Prototyping and Assembly Area Machine Shop Kitchen

7. Rules in Specific Lab Areas:Business/Design Computers, Programming, Electronics • No food or drink in these areas. • Remove all trash. • If you use anything, put it back where it belongs (i.e. pencils, pens, markers, etc.) • Avoid creating trip hazards – try not to run power cords or anything else across walkways • If necessary, use tape or something equivalent to secure to the floor. • Keep walkways cleared at all times. • Avoid letting parts and equipment clutter workspaces.

8. Specific Lab Areas: Prototyping/Assembly (Marked with tape on the floor of lab) • No food or drink in this area • Wear safety glasses, tie back long hair, no loose clothing or jewelry, wear closed toe shoes. If necessary, also wear ear protection. • Make sure you know how to use the tools and complete the task before you start. • Make sure you have the supervision of a trained mentor at all times. • Put tools back in their proper places after you use them. • Turn tools off and unplug them before adjusting. • Don’t distract or get too close to people working with tools.

9. Specific Lab Areas: Kitchen • Keep this area clean  (throw away trash) • Label your cups (so you can reuse them) • You are welcome to do your homework (but make sure you are signed out – no lab hours for HW) • No student use of the cabinets or the refrigerator.

10. Review What should you be wearing inside these specific lab areas? Who gets to open the refrigerator and cabinets in the kitchen?

11. Specific Lab Areas: Machine Shop • No food or drink! • Wear safety glasses • Long pants preferred • Use hearing protection • Make sure you have the supervision of a trained mentor at all times. • Know where the emergency stop button is! • Do not reach around or behind any operating piece of equipment. • Keep your hands out of the path of cutting surface. • Allow motor to reach full speed before beginning operations (e.g., cutting, grinding, etc.). • Know how to operate any machine you are going to use

12. Specific Lab Areas: Machine Shop Continued • Do not force any piece of equipment. The equipment cuts better and more safely at the rate for which it was designed. • If a part gets sucked into a machine, let it go and get out of the way.  Turn the machine off and have a mentor make sure the tool is safe to use again. • Do not leave the equipment until it has stopped completely. Turn the power off. • Keep the floor around the equipment clean and free of obstructions or clutter. • Don’t distract or get too close to people working on power tools or machines

13. Review! • Who can work alone in the machine shop? • What should you do if a part is jammed in a machine? • When should you walk away from a machine?

14. What if there is an accident or a “near miss”? 3 steps: HRR • H – Help!Get the First Aid Kit! Or, if a serious injury, call 911. • R – Report it!Report it to the Safety Captain and/or Team Captain! Make sure that they have reported it to Ms. K or another team mentor. • R – Reflect.Reflect on what we can do to avoid this in the future. • What was the cause of the accident? • What can we do to prevent it? • Should a new team policy be implemented?

15. Review! What three steps should you take if there is an injury in lab?

17. This part of the presentation only applies to students interested in fabrication, assembly, prototyping, etc.

18. Machine Shop and Fabrication Safety General Guidelines • Safety glasses and closed toe shoes are REQUIRED • Use hearing protection. • Think through the entire task before you start. If you have questions, ask a trained student or mentor. • Make sure you have the supervision of a mentor who is trained.

19. Machine Shop and Fabrication Safety General Guidelines Continued… • Before starting to use a piece of equipment, always check it for correct setup and always check to see if the equipment is clear by operating it manually, if possible. • If you are tired, hungry, hangry, or in a rush, do not use tools or machines! • Use hand protection for heat guns and lumber

20. Vertical Bandsaw Purpose: Cuts parts (wood and metal) and create curves in parts Rules: • Use proper speed settings and blades for cutting metal vs wood and plastic (finer teeth and lower speeds for metal). • When cutting sheet metal or metal that has less than 3 teeth of engagement, use low feed rate and take extra care. • Lower the blade guide to right over the material.

21. Vertical Bandsaw Continued Rules: • Use vacuum to clean up. • Use multiple cuts for corners. • No sharp turns when the blade is in the material. • Never have any fingers or anything else you don't want cut in line with the blade. Use a push stick for small pieces.

23. Horizontal Bandsaw Purpose: Cuts angles into parts and sizes materials like wood and metal Rules: • Never push down - the blade will bind and come off the track if you do. • Always clamp your part. Parts that can not be clamped should be cut on the vertical bandsaw • Watch the blade carefully.

24. Horizontal Bandsaw Continued • Never have any fingers or anything in line with the blade. • If you are cutting small parts be careful picking them up - they may be hot (the freshly cut surfaces of larger parts too).

26. Review! What is the difference between Horizontal Bandsaw and Vertical Bandsaw? What is the purpose of each bandsaw? What should you do before using a vertical blade? What should you do after using a vertical blade? Horizontal Blade?

27. Hand Drills and Air Drills Purpose: Used for riveting, prototyping, assembly, etc! Rules: • Clamp your work. • Do not have your hand or anything else in front of the bit  - the bit could go through your work and into your hand. • If the drill is running slowly, get a new battery. • Tighten drill bit completely. • Drill at a right angle to your part unless you want an angled hole.

28. Hand Drills and Air Drills Continued • When drilling through metal, put a scrap piece of wood underneath so that you drill into the wood, not the surface below. • Make sure to put it on the correct speed, clutch, and direction settings. • Do not use large diameter cutting bits as they catch easily and cause the drill body to spin.

30. Soldering Pencil Purpose: Solders wires and circuit boards Rules: • Wear Safety Glasses • Keep the tip clean • Keep fingers clear • Don't touch the metal part of the tip when it's hot - it will burn you or other things. • Use pliers to hold work pieces when appropriate.

31. Soldering Pencil Continued Take care of the tip: • Keep solder on • Wipe it on a water moistened sponge to remove excess solder and oxidation (black stuff).

33. Review! Steve watched a video about how to unlock the secret headphone jack in iPhone 7. What safety procedure does he needs to do before drilling? What do you need to do before using the soldering pen? What to do after using a soldering pen?

34. Sheet Metal Shear Purpose: Cuts sheet metal or polycarbonate • Never bend material thicker than .090 Aluminum, .125 Polycarbonate, and .060 mild steel. • Never bend round rod or thin walled tubing, regardless of size. • Never put your fingers between the dies, particularly when positioning the metal.

35. Sheet Metal Shear • If operating with two people (one positioning and one actuating the lever), ensure that no one has their fingers between the dies and do not lower the die unless directed by the person positioning the metal. • Bend in the center of the dies when possible. • When bending at the edge, balance the forces with a sacrificial piece of same thickness at the other end of the die. • Do not change dies without a mentor helping. • Stop pulling and get out of the way if the machine ever threatens to tip.

36. Sheet Metal Brake Purpose: bends metal Rules: Wear safety glasses Do not bend material that is too large for the machine If bending plastic, make sure plastic is heated with a heat gun

38. Review! Difference between Sheer and brake? Can you cut rod or tube on a sheer? What to do before bending a plastic on the brake?

39. Benchtop Grinder Purpose: to grind steel or aluminum (like sanding wood) Rules: • Do not use gloves • Make sure your hand is clear and hair is tied back • Use safety glasses • Use vise grippers to hold materials • Use the correct grinding wheel for the material grinding • Rest the material or the vise grip against the hard stop

41. Review! Should you use gloves on the benchtop grinder? How should you use the grinder?

42. All Machines Review Questions! What is the difference between Horizontal Bandsaw and Vertical Bandsaw? What do you need to do before and after using soldering pen? What is the purpose of the Grinder? What is the difference between the Sheer and Brake?
