Anti-static precautions
Have you ever walked across a carpeted floor and gotten a shock when you touched a doorknob, table, counter, or even another person?
That little shock you got was a result of static electricity. It was also many times what is needed to destroy some computer components.
Humans can't feel a static shock until it is some thousand volts strong, but it takes less than 30 volts to damage a sensitive computer component, such as a stick of RAM or a processor.
That's why computer technicians and home computer producers have to protector their computers against the deadly ravages of static electricity, as well as take steps to avoid injury to yourself. A shock that you can't even feel can seriously damage your homebuilt computer before you're even finished building it.
If the discharge is stroked then the voltage was probably over 2000 volts (for comparison mains electricity is 230 volts). If you hear the discharge then it would be around 2000-7000 volts. If you see a small blue spark then the voltage was probably over 10 000 volts.

Safety and anti static Rules:
- Don’t work in carpeted areas.
- Warring something’s called an anti-static wrist. Something’s fit with the wrist and the end of the wire put it on the metal computer box as it shows on the picture.
- A better anti-static kit is something we put it under the computer to give all the protection for us and also to avoid our tables from scratches.
- Using a antic static gloves when we touched an electronic components of the computer.
- Touched an electronic component with non-metallic
things edge.
- Never plug an ATX power supply into AC power unless it is connected either to a computer's motherboard or to a dummy test load.
- Never eat, drink, or smoke while working on a computer.
Never used an Anti-static wrist while using an CRT monitor:
Never used an anti-static wrist strap which working on a CRT monitor, even if it is unplugged, because the monitor has a high voltages which reach a 40,000 volts. It holds for long time. For example, if the person used a CRT monitor’s flyback transformer while you are stranded to the monitor's chassis by a wrist strap, you will probably die.

Summary:
When we using our computers or changing something on it we have to thing of the anti static precaution. we have to took our protection from the electronic components that the computer has. we have to use the anti static wrist when we used the computer for some of the computers. Don't drink, eat or smoke during using the computer.Also,warring a gloves that for the electronic.
