E11/E12 Lab Rules

  1. After the lab is completed, return all the equipment to its proper storage location.
  2. If in doubt about electrical safety, see the laboratory instructor. Regarding specific equipment, consult the instruction manual provided by the manufacturer of the equipment. Information regarding safe use and possible- hazards should be studied carefully.
  3. Be as neat as possible. Keep the work area and workbench clear of items not used in the experiment.
  4. Shoes must be worn at all times.
  5. There must be at least two (2) people in the laboratory while working on live circuits.
  6. Keep the body, or any part of it, out of the circuit. Where interconnecting wires and cables are involved, they should be arranged so people will not trip over them.
  7. Always check to see that the power switch is OFF before plugging into the outlet. Also, turn instrument or equipment OFF before unplugging from the outlet.
  8. When unplugging a power cord, pull on the plug, not on the cable.
  9. When disassembling a circuit, first remove the source of power.
  10. 3-to-2 prong adapters are prohibited unless an adequate separate ground lead is provided, the equipment or device is double insulated, or the laboratory ground return is known to be floating..
  11. Keep fluids, chemicals, and heat away from instruments and circuits.
  12. Report any damages to equipment, hazards, and potential hazards to the laboratory instructor.
  13. If working with voltages greater than 40 Volts, remove all loose conductive jewelry and trinkets, including rings, which may come in contact with exposed circuits.
  14. Consider all circuits to be "hot" unless proven otherwise.
  15. When making measurements of voltages greater than 40 Volts, form the habit of using only one hand at a time. No part of such a live circuit should be touched by the bare hand.
  16. After the lab is completed, return all the equipment to its proper storage location.
