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.
- Handle with Clean Hands – Always wash and dry hands before using a computer to prevent dirt from damaging the hardware.
- Avoid Eating or Drinking Near the Computer – This prevents spills that can cause short circuits.
- Use a Stable Power Supply – A UPS (Uninterruptible Power Supply) protects the computer from sudden power surges.
- Turn Off and Unplug When Not in Use – This prevents overheating and protects the computer from power-related damage.
- Keep Vents and Fans Unblocked – Proper ventilation prevents the system from overheating.
- Use the Computer in a Clean and Dry Environment – Dust and moisture can damage internal components.
