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
Objective 101.01 Safety
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.
Objective 101.01 Safety
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
Objective 101.01 Safety
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.
Objective 101.01 Safety
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.
Objective 101.01 Safety
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
Objective 101.01 Safety
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.
Objective 101.01 Safety
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.
Objective 101.01 Safety
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.
Objective 101.01 Safety
Electrical Fire Safety Fire extinguishers are divided into four
classes. Use a Class C fire extinguisher for electrical and electronics files.
Objective 101.01 Safety
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.
Objective 101.01 Safety
Cable Management Organize cables.
Make sure cables are not located where people can trip on them.
Objective 101.01 Safety
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.
