R-502 refrigerant cylinders are colored which of the following?

R-502 refrigerant cylinders are specifically colored orchid. This designation is part of a color-coding system used to identify refrigerants easily and ensure safe handling. The orchid color helps users in the refrigeration and air conditioning industries distinguish R-502 from other refrigerants, which may use different colored cylinders. This is an important safety measure, as using the wrong type of refrigerant can lead to equipment damage or unsafe conditions.

Other refrigerants have their own unique color codes; for instance, R-22 is typically green, while R-12 cylinders are often colored white. Knowing these color codes is essential for professionals in the field to prevent mix-ups and ensure compatible handling and usage of refrigerants. This knowledge aids in maintaining safety standards and complying with regulations regarding refrigerant management.
