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 and yellow
c.Solid green
d.Solid light blue
Giải thích
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.
