What must recovered refrigerant be stored in?

Recovered refrigerant must be stored in properly marked cylinders due to several important safety and regulatory reasons. These cylinders are designed specifically for refrigerant storage and comply with standards established by organizations like the Department of Transportation (DOT) and the Environmental Protection Agency (EPA).

Using properly marked cylinders ensures that the type of refrigerant is clearly identified, which is essential for safe handling, transport, and compliance with environmental regulations. The cylinders are constructed to withstand the pressure of the gases they contain, reducing the risk of leaks or ruptures. Additionally, the markings provide essential information such as the chemical name, hazards, and instructions for emergency situations.

In contrast, storing refrigerant in plastic containers or any available container would not meet safety standards and could lead to leakage, contamination, or other hazardous situations. Metal drums, while sturdy, may not provide the necessary certification or labeling that specifically marked cylinders do, potentially leading to regulatory issues or unsafe practices.
