Question 210Refrigeration & AC - Assistant Engineer

The correct answer is D) goggles and gloves. Personnel servicing refrigeration systems should wear goggles and gloves as personal protective equipment (PPE) when exposed to commonly used refrigerants. This is because refrigerants can be irritants to the eyes and skin, and goggles and gloves help protect the worker from direct contact. The other options are not the appropriate PPE for this task - rubber soled shoes do not provide protection, a respirator is not necessary for refrigerant exposure, and a gas mask is overkill for this application.
