Which of the following actions should be avoided when working with recovery and recycling equipment?

Operating with a known malfunction can pose significant risks, including improper refrigerant recovery and potentially dangerous leaks. Recovery and recycling equipment must function correctly to ensure that refrigerants are safely removed from systems and stored. Malfunctions can lead to inefficiencies, environmental harm, and safety hazards, not just for the technician but also for the surrounding environment.

In addition to the operational risks, using malfunctioning equipment may also violate EPA regulations regarding the handling of refrigerants, which is critical for compliance and environmental protection. Regular checks and servicing of recovery and recycling equipment are essential, and training personnel on safety procedures is imperative for maintaining safety standards in the workplace. Thus, it's vital to address any known equipment issues before use to ensure both regulatory compliance and safety.
