How to Protect a Computer From ESD

Protecting electronic components, such as personal computers, from electrostatic discharge (ESD) is a simple task if proper handling, material and understanding of the issue are employed. ESD is a built-up charge of imbalanced electrons on the surface of material.

Difficulty: Moderate

Instructions

Things You'll Need:

• ESD wrist strap
• Shoe sole grounder
• Conductive shoes

1. Ensure that the relative humidity of the building or room containing the computer is above 40 percent. Controlling humidity is a key factor in protecting computers from ESD. Dry air conditions feed ESD, whereas a more humid climate hinders it.

2. Make certain that all electronic components, including the computer, are connected to a common ground. Any charge that has built up and is potentially threatening the computer will be discharged safely through the common ground.

3. Wear protective implements such as wrist straps, sole grounders and conductive shoes. These devices help to eliminate electrostatic charge from building.

4. Transport computer peripherals and components in anti-static material bags.

5. Make certain when working on the inside of the computer case, installing or cleaning components, that the personal static charge has been discharged by touching the inside of the metal case housing before handling components.

Tips & Warnings

• Keep any ungrounded persons at least 4 feet away from an ESD sensitive computer.
• Consider installing an air ionizer in the room with the computer to balance charged particles.
• Install ESD warning stickers or signs in areas where vulnerable computers are being used.
• Most of the needed items to protect against ESD can be found and purchased at electronic specialty stores, like Radio Shack or Circuit City.
• Never keep plastic bags, folders or envelopes near an exposed computer.
• ESD is a very powerful force that can be potentially deadly if proper precautions are not taken to ensure adequate discharge of energy.
