tHE KEYWORD HERE IS 'SAFETY'
Safety here means, a condition or a measure taken to protect computers from unlikely damage, risk, danger or burglary.
POSSIBLE PRECAUTIONARY MEASURES
1. BURGLAR PROOFING
Physical access to the computer room should be restricted to ensure that only authorized persons get access to the computers.
To prevent unauthorized access to the computer room, the following controls should be implemented:
Both computers and human beings emit heat energy into the environment. Therefore, the computer room must have good circulation of air to avoid overheating and suffocation.
Proper ventilation enables the computers to cool, and therefore, avoids damaging the electronic parts.
The following facilities can ensure proper ventilation in a room:
3. DUST CONTROL
The service should include; blowing dust from the System unit, cleaning the floppy drives, cleaning the Keyboard, cleaning the Monitor externally, and also cleaning all peripheral devices such as Printers and Mouse.
4. DUMP CONTROL.
Humidity in the computer laboratory must be regulated to remain at an optimum 50%. If the humidity is low, it allows static electricity to build up and causes damage to sensitive electronic components. Similarly, high humidity of over 70% causes rusting of the metallic parts of the computer system.
5. HANDLING OF MATERIALS & EQUIPMENT.
Computer devices must be handled with a lot of care as they are extremely fragile and can easily get damaged. Dropping or bumping can cause permanent damage on the device, e.g., to transport the System unit always handle it on its frame.
