What is the maximum allowable pressure for recovering less than 200 lbs of refrigerant after Nov. 15, 1993?

The maximum allowable pressure for recovering less than 200 lbs of refrigerant after November 15, 1993, is 0 psig. This regulation aims to ensure that the recovery of refrigerants is conducted safely and effectively, promoting environmentally responsible practices.

When recovering refrigerants, it is essential to minimize the pressure to prevent the release of substances that can harm the ozone layer or contribute to global warming. Achieving a target pressure of 0 psig means that the refrigerant recovery process is effective in eliminating any remaining refrigerant from the system, thereby preventing potential leaks into the atmosphere.

Additionally, lower pressures during recovery reduce the risk of causing pressure-related damage to refrigerant systems and tanks, ensuring that all operations are performed safely and in compliance with environmental regulations. The establishment of 0 psig as the maximum allowable pressure is part of a broader framework of guidelines that govern the handling of refrigerants.
