Core (Universal)Question 29 of 240
A technician needs to identify a cylinder by its color. Which color has EPA and industry designated for refrigerant recovery cylinders?
a.Solid orange
b.Gray body with a yellow top (shoulder)
c.Solid green
d.Solid light blue
Explanation
Refrigerant recovery cylinders are color-coded with a gray body and a yellow top or shoulder so they are easy to distinguish from virgin refrigerant cylinders. Solid colors such as green (older R-22), orange (R-404A), and light blue (R-134a) identify specific virgin refrigerants, not recovered mixtures. The gray and yellow scheme signals that the contents may be a mix that must be reclaimed or reused properly.
