Q

You dropped a screw into a tight location of a computer. How should you retrieve it?

Use a magnetic-tipped screwdriver

Use a magnetic grabber

Use a three-pronged grabber

A

Use a three-pronged grabber

A three-pronged grabber should be used to retrieve the screw from the computer. Using a magnetic-tipped screwdriver is not advisable, because many components are sensitive to magnets. Using a magnetic grabber is not advisable, because many components are sensitive to magnets. Shaking the computer until it falls out can be dangerous and make the screw harder to get out

Q

You have a failed CRT monitor that you must dispose of safely. Which of the following is used to discharge voltage properly from the unplugged computer monitor?

Antistatic wrist up

Screwdriver

High-voltage probe

A

High-voltage probe

A high-voltage probe can dissipate the high voltage stored in a CRT. An antistatic wrist strap should not be worn near a high-voltage potential such as a CRT monitor. A screwdriver can dangerously arc the voltage and is not the proper way to discharge the unit. A power cord supplies power to a CRT monitor

Q

In the interest of a safe work environment, which of the following should you report? (Choose two)

An accident

A near-accident

Spills on the floor inside a building

Rain forecasted for a workday

A

An accident

Spills on the floor inside a building

An accident should always be reported, so that if there is a hazardous condition, it can be fixed. Report hazardous conditions, such a spill on the floor, to the employer before they are a problem. A near-accident does not need to be reported unless it is caused by a hazardous condition, like spills. Rain forecasted for a workday is not a hazardous condition

Q

What is the approximate minimum level of static charge for humans to feel shock?

300 volts

3,000 volts

Q

Your work environment has been unusually dry lately, and several components have been damaged by ESD. Your team has been asked to be extra careful about ESD damage. Which of the following measures can be implemented to reduce the risk of ESD? (Choose two)

Use an antistatic wrist strap

Use an antistatic bag

Spray disinfectant spray

Shuffle your feet

A

Use an antistatic wrist strap

Use an antistatic bag

Using an antistatic wrist strap allows you to ground yourself to dissipate a static charge. Using antistatic bags allows for a uniform charge around a component. Spraying disinfectant spray will only kill germs, not reduce static. Shuffling your feet will build a charge of static

Use a cart for heavy objects

Ensure that there are no safety hazards in your path

You should use a cart to move heavy objects. You should also ensure that no safety hazards are in your path. Lifting by bending over at the waist can hurt your back. Carrying CRT monitors with the glass facing outward is not safe, as the weight will be farthest from your body

Q

Which of the following are elements of a good workplace safety plan? (Choose two)

Periodic workplace inspections

A safety and health-training program

Retribution for employees who report violations

An independent third-party auditor of the safety plan

A

Periodic workplace inspections

A safety and health-training program

Good safety plans protect the interests of the workers and also help to keep company costs down. Periodic workplace inspections and a training program are good components to implement. Employees cannot be punished in any way for reporting safety violations. Third-party audits of safety programs are not necessary, but can complement periodic inspections and safety/health-training programs

Q

What is the recommended use policy on magnetic-tipped screwdrivers inside computers?

Do not use them

It’s okay to use them, but keep them away from the processer

It’s okay to use them, but keep them away from the RAM

A

Do not use them

A good rule of thumb when it comes to magnetic-tipped screwdrivers is to avoid using them inside a computer case. Magnetic tools can damage data on disks that use a magnetic storage scheme. Magnetic-tipped screwdrivers should not be used inside a computer even if they are kept away from the processor. Magnetic-tipped screwdrivers should not be used inside a computer even if they are kept away from the RAM. Regardless of whether they are powered or not, magnetic-tipped screwdrivers should not be used inside computers

18
Q

Which of the following are usually contained on an MSDS? (Choose two)

Freezing point

Handling and storage instructions

Personal protection instructions

Salinity levels

A

Handling and storage instructions

Personal protection instructions

Material safety data sheets (MSDSs) contain handling and storage instructions as well as personal protection instructions. MSDSs do not contain freezing point specifications or salinity levels

19
Q

Which of the following are OSHA requirements for a safe work environment that must be followed by employees? (Choose two)

Immediately report all incidents of OSHA

Use protective gear and equipment

Attend safety training

Follow all employer implemented health and safety rules

A

Use protective gear and equipment

Follow all employer implemented health and safety rules

To maintain a safe work environment, all employees must follow certain protocols. These include using protective gear and equipment and following all health and safety rules. Accidents must be reported to the employer, not OSHA (unless action is not properly taken by the employer). There are no rules requiring safety training, although it is a good idea to have these sessions and for employees to attend them

20
Q

Which of the following types of batteries are not considered environment hazards?

Nickel-metal hydride (NiMH)

Nickel-cadmium (NiCd)

Button cell

A

Nickel-metal hydride (NiMH)

Nickel-metal hydride (NiMH) batteries are not considered environmental hazards. Alkaline batteries used to contain mercury, which is an environmental hazard, so they are assumed to be environmental hazards. Nickel-cadmium (NiCd) batteries and button cell batteries are considered environmental hazards
