220-1102 Question 718
Single answerSafety gogglesA technician is replacing a cracked smartphone screen in a repair shop. The old glass is already splintering, and the technician will use a heat gun and prying tools to remove the display. The manager notices the technician is only wearing nitrile gloves. Which additional protective equipment is MOST appropriate to reduce the risk of injury during this task?
- A
ESD wrist strap
- B
Safety goggles
- C
Back support belt
- D
Hearing protection earmuffs
Show answer and explanation
Correct answer: B
Explanation
The correct answer is safety goggles because the scenario involves a clear eye hazard: cracked glass, prying tools, and heat-assisted removal of a damaged screen. In A+ Core 2 safety objectives, technicians are expected to identify and use appropriate personal protective equipment (PPE) based on the specific risk present. Eye protection is a best practice whenever there is potential for flying particles or broken glass. While ESD precautions may also be appropriate in electronics repair, they do not replace PPE for personal safety. This aligns with common workplace safety guidance, including general OSHA PPE principles that require suitable eye protection when employees are exposed to flying particles, molten material, or similar hazards.
- A. Incorrect.
An ESD wrist strap helps protect electronic components from electrostatic discharge, but it does not protect the technician's eyes from glass shards or debris. A candidate might choose this because ESD protection is important in electronics work, but it addresses a different hazard than the one described in the scenario.
- B. Correct.
Safety goggles are the best choice because the technician is working with cracked glass and using tools and heat that could cause small fragments to fly upward or outward. Proper eye protection is a standard safety practice when performing repairs that involve shattered screens, cutting, scraping, or prying materials.
- C. Incorrect.
A back support belt is not the most appropriate protection for this task. These belts are sometimes associated with lifting tasks, but the scenario's primary risk is eye injury from splintering glass, not strain from moving heavy equipment.
- D. Incorrect.
Hearing protection earmuffs are useful in loud environments, but smartphone screen replacement does not typically create hazardous noise levels requiring earmuffs. This option is plausible only because power tools may be used in some repair settings, but it does not address the immediate and most significant hazard in this case.
