Lesson Content

Safety Precautions in Using Computer hardware

A safety precaution is a careful action taken to prevent accidents, injuries, or damage when using a computer.

The following are safety precautions to take when using computer hardware:

1. Handle with Clean Hands – Always wash and dry hands before using a computer to prevent dirt from damaging the hardware.
2. Avoid Eating or Drinking Near the Computer – This prevents spills that can cause short circuits.
3. Use a Stable Power Supply – A UPS (Uninterruptible Power Supply) protects the computer from sudden power surges.
4. Turn Off and Unplug When Not in Use – This prevents overheating and protects the computer from power-related damage.
5. Keep Vents and Fans Unblocked – Proper ventilation prevents the system from overheating.
6. Use the Computer in a Clean and Dry Environment – Dust and moisture can damage internal components.
7. Avoid Overloading Power Outlets: Do not plug too many devices into one outlet to prevent electrical hazards.
8. Regularly Clean the Computer: Use a soft, dry cloth to clean the computer case, screen, and keyboard to remove dust and debris.
9. Use Surge Protectors: Protect your computer from voltage spikes by using surge protectors.
10. Position Cables Properly: Arrange cables to prevent tripping hazards and avoid damage to the cables themselves.
