When installing/removing computer hardware and other peripherals:
Wear proper apparel
Avoid acrylic or wool sweaters when working with electronic parts
Do not wear loose fitting clothing, rings, bracelets etc
Unplug all computer equipment and peripherals before opening any covering cases
Keep your work area clean and well lit
Check for damaged parts
Do not force components into computer ports
Use an anti-static wrist strap or discharge yourself by touching a grounded metal object such as a computer casing
Power supplies produce several levels of voltage. Read the information on the power supply carefully and make sure that the power supply you are using is appropriate for the application
Replace all cases or coverings after inspections or installations
Check all circuits and installations with the instructor before power is applied
Retain all screws during disassembly in containers such as film canisters for proper reassembly
