Type II — High-PressureCâu 159 / 240
A commercial refrigeration appliance holds more than 50 pounds of an ozone-depleting refrigerant and has developed a leak. Under the Section 608 leak-repair requirements, what must the owner or operator generally do?
a.Nothing, because leaks under 50 pounds are exempt
b.Vent the remaining charge and refill
c.Repair leaks when the appliance's leak rate exceeds the applicable threshold, or follow a retrofit/retire plan
d.Replace the refrigerant with air
Giải thích
For appliances containing more than 50 pounds of an ozone-depleting refrigerant, owners and operators must repair leaks when the annual leak rate exceeds the applicable regulatory threshold, or otherwise follow a plan to retrofit or retire the equipment. Timely leak repair reduces refrigerant emissions. Venting is never an acceptable response to a leak.
