When do we need to wear butyl lined gloves?

• A. During all service
• B. Only when high temperature
• C. Only when ambient temperature above 90F
• D. When connecting and disconnecting hoses

Answer: (D)

Butyl lined gloves are used for chemical protection when there’s a real risk of skin contact with refrigerants and related fluids. The most exposure happens when hoses are connected or disconnected, because leaks or sprays can occur at those connection points. Wearing the gloves at that moment minimizes skin contact with any leaking refrigerant or system oil. It isn’t about temperature or about wearing them for all service—it's about protecting your hands during the hose connection/disconnection steps when exposure is most likely. If you’re wearing them, also ensure they’re intact and change them if damaged or contaminated.
