Computer Engineering Technology I – 2014-15 Pilot Objective 101.01

Use appropriate safety procedures.

Course Weight : 2%

Objective 101.01 Safety

Given a scenario, use appropriate safety procedures for computer equipment. ESD straps ESD mats Self-grounding Equipment grounding

CompTIA A+ Certification Standard 5.1


ESD straps Electrostatic discharge takes

place when two objects that store different amounts of static electricity come in contact. To avoid ESD, keep the technician and the parts of the PC on which he is working at the same electrical potential. The technician can be grounded to the PC by connecting an anti-static wrist strap from the PC to himself.


ESD mats

PC components may pick up static electricity when set aside while a technician is working on them. Placing components on an anti-static mat can prevent this problem


Self-grounding When a technician touches an unpainted

part of the computer chassis it is known as self-grounding. If there is no anti-static wrist strap or mat available then this is a good next choice for ESD protection.


Equipment grounding When a low-resistance path that directs

unwanted current directly to the Earth this is known as equipment grounding. Three-prong power cords are common examples of this type of ground conductor.


Given a scenario, use appropriate safety procedures for humans working around electrical equipment. Disconnect power before repairing PC Remove jewelry Lifting techniques Weight limitations Electrical fire safety CRT safety - proper disposal Cable management


Disconnect Power When working on a

PC make sure to de-energize, or remove power from, the equipment. You can accomplish this by switching it off and use a ground plug to assist with removing ESD.


Remove jewelry An easy way to get shocked is to wear

anything conductive that might touch an energized part of a computer being repaired.

Take off rings, watches, bracelets, and metal pieces that might dangle into the computer.


Lifting techniques and weight limitations Use proper lifting techniques; lift with

your legs and not your back. Every individual has different physical

strength limitations. You must know the limits of your own strength.


Electrical Fire Safety Fire extinguishers are divided into four

classes. Use a Class C fire extinguisher for electrical and electronics files.


Proper disposal of CRT Monitors Avoid the inside of a CRT monitor

because of the possible presence of toxic substances, such as lead or mercury.

The monitor can explode, if damaged, and expose people to injury.

CRT monitors should always be properly recycled and should NOT be thrown in the trash or land field.


Cable Management Organize cables.

Make sure cables are not located where people can trip on them.


Government Regulations OSHA maintains rules and regulations for

workplace safety. Workplaces are required to post the “Job

Safety and Health” poster in a prominent place where employees will see it.

Employers are required to make their work places safe for their employees.

The EPA maintains guidelines for electronic waste disposal.
