Computer Engineering Technology I – Pilot Objective Use appropriate safety procedures. Course Weight : 2%

Objective 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 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 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 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 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 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 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 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 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 Safety  Electrical Fire Safety  Fire extinguishers are divided into four classes. Use a Class C fire extinguisher for electrical and electronics files.

Objective 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 Safety  Cable Management  Organize cables.  Make sure cables are not located where people can trip on them.

Objective 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.
