PC CARE AND SAFETY PROCEDURES FOR USERS

How to take care of your PC.
1.Computer need a good working temperature to work properly. They need to be placed in a cool and dry place. You can maintain good temperature with an electric fan or air conditioning.

2. All the cables and connectors must be tied together to keep them away from walkways to avoid accident.

3. Refrain from eating in front of a computer. Food bits attract insects like ants and cockroaches that can penetrate the hardware and cause computer malfunction. Spilled drinks, on the other hand, might cause short circuits.

4. Always use an AVR (Automatic Voltage Regulators) to regulate the electricity. Too much electric voltage might cause the unit to short. Also, turn off computers during lightning as these can cause electrical surges to the computer.

5. Do not bump or drop the computer peripherals or components as any damage may cause them to malfunction.

6. Avoid clutter around your computer. Use soft cloth in cleaning your computer to avoid scratches.

7. Always scan for computer viruses. Internet connection and external storage devices often carry viruses that could damage files and cause software malfunctions.

USER’S HEALTH RISKS AND PREVENTION

                PC’s are said to be “user-friendly” but this doesn’t mean using them does not have health risks. There isn’t a conclusive evidence that computers emit enough radiation to harm us. Rather, the damage to health may include eyestrain, wrist injury, and pains in the head, shoulder, back, and neck due to prolonged use of computers.
