Computer Hardware Servicing Safety and Precautions

TESDA NC II Computer Servicing also requires to learn about the Computer Hardware Servicing Safety and Precautions. The only danger to you in most of these devices is the AC line connection. Before you plug in the unit with any covers removed, make note and cover up any exposed AC line connections.  The rest of the circuitry is low voltage and while you can destroy your equipment by your actions, you should be fairly safe. The following SafetyGuidelines are included for your survival when working on line connected or high voltage equipment.

• Don't work alone - in the event of an emergency another person's presence may be essential.
• Always keep one hand in your pocket when anywhere around a powered line-connected or high voltage system.
• Wear rubber bottom shoes or sneakers.
• Don't wear any jewellery or other materials that could accidentally contact circuitry and conduct current, or get caught in moving parts. (Bracelets, long necklaces)
• Don't attempt repair work when you are tired.  Not only will you be more careless, but your primary diagnostic tool - deductive reasoning - will not be operating at full capacity.
• Finally, never assume anything without checking it out for yourself!  Don't take shortcuts!
