2.  This class may frequently involve the use of computing and networking equipment.  It is important to understand a few safety principles that are key to protecting both user and equipment. COMPUTER EQUIPMENT SAFETY

3. PROTECTING USERS FROM HARM

4. What is electrical shock? Sudden stimulation of the nerves or convulsive contraction of the muscles that is caused by the discharge through the body of electricity from a charged source, OR exposing yourself to live electrical circuits ELECTRICAL SHOCK

5. Be sure equipment is unplugged before servicing. Do not open power supplies or other high voltage components. Be aware capacitors can hold a charge even after device is unplugged. PREVENTION OF SHOCK

6. Avoid sharp edges on the sheet metal inside some computer cases. Use caution when unplugging some connectors, because they can require much effort and may come apart abruptly, causing injury to the hand. CUTS

7. Electronic components, especially CPUs, can become very hot. Use caution when touching electronic parts. BURNS

8. PROTECTING EQUIPMENT FROM HARM

9. What is electrostatic discharge? Transfer of electrical charge between any two objects Although not usually dangerous to the technician, ESD can cause permanent damage to internal computer components, such as RAM ELECTROSTATIC DISCHARGE

10. Special precautions, such as wearing a wrist strap, must be taken when servicing equipment PREVENTION OF ELECTROSTATIC DISCHARGE

11.  Connectors both within and outside computing equipment are both precise and fragile.  Always use an appropriate amount of force when inserting or removing connectors.  Most connectors should not be pulled at an angle.  Use caution with exposed connectors to ensure pins do not get bent. PROPER CONNECTOR HANDLING

12.  Have safe fun and ask questions!  The instructor is eager to answer questions related to the equipment you are studying. COMPUTER EQUIPMENT SAFETY
