Your work throughout (particularly on the hardware), must conform to current health and safety requirements.

The most important thing is that when you are working with hardware makes sure the electric wires such as power supply is unplugged. While you are working with hardware make sure don’t touch those stuff which you really don’t know what you have to done with them. You should use a fully adjustable chair as this will avoid poor posture. Make sure there is no liquid substance around you which will accidentally affect the hardware. Take several breaks and keep you self moving to keep your self away from back ache. Make sure the monitor is eyelevel and your hands are supported when you are typing and make sure that you feet touch the floor properly. To prevent Strain Injury, you should use wrist rests and have a five-minute break from typing every hour.
