Type II — High-Pressure第 159 / 240 题
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.Vent the remaining charge and refill
b.Nothing, because leaks under 50 pounds are exempt
c.Repair above the leak-rate threshold
d.Replace the refrigerant with air
解析
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.
