What type of personal protective equipment (PPE) should you use when working with refrigerants?

When working with refrigerants, it is essential to use appropriate personal protective equipment (PPE) to safeguard against potential hazards associated with these chemicals. Safety goggles and gloves are the correct choice because they provide essential protection. Safety goggles shield the eyes from splashes and harmful vapors that can arise when handling refrigerants. These vapors can be irritating or damaging to the eyes.

Gloves are crucial for protecting the hands from direct contact with refrigerants, which can cause skin irritations or frostbite due to their low temperatures. Using the right type of gloves, typically chemical-resistant gloves, increases safety during handling and prevents exposure to potentially harmful substances.

The other options listed do not adequately address the specific risks posed by refrigerants. Face masks and earplugs protect against respiratory and noise hazards, which are not primary concerns when handling refrigerants. Hard hats and safety boots are vital for certain construction and industrial environments but are not directly related to the risks associated with refrigerants. Welding gloves and masks are designed for high-heat operations and do not provide the appropriate chemical protection needed when working with refrigerants. Therefore, the combination of safety goggles and gloves is the most appropriate form of PPE for this specific task.
