What safety measure should be taken when handling refrigerants?

Wearing protective eyewear is essential when handling refrigerants because these substances can pose serious health risks if they come into contact with the eyes. Refrigerants can cause severe irritation and chemical burns, and exposure to refrigerant vapors can also be harmful. Protective eyewear acts as a barrier to prevent accidents and ensure that technicians can work safely in environments where refrigerants are present.

Additionally, prioritizing safety measures, such as using proper personal protective equipment (PPE), is part of industry best practices and helps to maintain a safe working environment. This practice reflects the need to safeguard one's health while working with materials that can be hazardous if mishandled. Ignoring safety precautions could result in serious injuries, hence the other choices do not align with safe operating procedures.
