Which of the following releases of refrigerant is NOT considered illegal venting under Section 608?
a.Opening a system to atmosphere before recovering the charge
b.A small release of nitrogen or CO2 used as a holding charge or for leak detection
c.Blowing R-22 out of a line set to clean it
d.Discharging R-134a to test a gauge manifold
Giải thích
Releasing a holding or trace gas such as nitrogen or CO2 that is not a regulated refrigerant is not considered illegal venting, which is why these gases are used for pressure testing and leak detection. Opening a system before recovery, blowing out refrigerant, or discharging R-134a are all prohibited releases of regulated refrigerant. The rule targets ozone-depleting and substitute refrigerants, not inert test gases.
