Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact. ESD often creates visible sparks, but also has less dramatic forms which may be neither seen nor heard, yet large enough to cause damage to sensitive electronic devices like computers.
ESD can happen when you are working with the computer, in which a person develops a potential charge which can damage the parts of computer which he touches. This occurs when working with the internal components of the computer and can happen without the knowledge of the user.
How to prevent the ESD
ESD can be prevented by grounding yourself to make sure that you and computer are at zero potential.
This band is a strap that around the users wrist and the cord coming out of the wrist band contains a clip. This keeps the users grounded continuously by discharging the any static electricity generated by the user.
This band should be strapped around the wrist and the clip from the cord needs to be attached to a non painted metallic surface. User should wear this band as long as they are working with the internal parts of the computer.
This is a special type of mat and the computer should be kept on the mat before disassembling the internal components. This mat removes any static electricity generated by the user.
Touching the Non Painted Metallic Surface
By continuously touching the Non Painted Metallic Surface, the static electricity is discharged from the user. User can also touch the metallic part of the computer chassis.
Standing when Working
Sitting on the chair generates more static electricity than standing when working with the computer. So it is highly recommended to stand when you are working.
Avoid wearing clothes like woolen clothes that generate static electricity easily.
It is best advised to remove jewelry or any metallic accessories to prevent the ESD.
