What approval is necessary for recovery cylinders used in HVAC applications?

Must have a green label
Must be DOT approved with a yellow top and grey body
Must be inspected by local authorities
Only FDA approval is required

The correct answer is: Must be DOT approved with a yellow top and grey body

Recovery cylinders used in HVAC applications must be DOT approved with a yellow top and grey body because this designation indicates compliance with the Department of Transportation's regulations for the safe transportation and storage of refrigerants. The color scheme is important as it helps differentiate recovery cylinders from other types of cylinders that may contain different substances, further ensuring compliance with safety protocols. DOT approval ensures that the cylinders are constructed to withstand the pressures that refrigerants exert and are built from materials that can safely contain those substances. This is crucial for preventing leaks and ensuring safe recovery of refrigerants during servicing or disposal, which aligns with environmental regulations. The specifics of the color coding also aid technicians in quickly recognizing equipment and adhering to best practices for safely handling refrigerants. This recognition and adherence to safety standards is essential in the HVAC industry to protect both the workers and the environment.
