Type I — Small Appliances第 108 / 240 题
A recycling center employee, who is not an HVAC technician, is the last person to handle scrap refrigerators before shredding. What must the facility ensure?
a.Nothing, because only certified technicians have recovery duties
b.Refrigerant has been recovered by a certified technician or the facility verifies recovery with a signed statement
c.Each unit is filled with nitrogen
d.The refrigerators are painted before shredding
解析
The final person in the disposal chain must ensure the refrigerant was recovered, either by having a certified technician recover it or by keeping a signed statement that recovery already occurred. This prevents refrigerant from being released when appliances are shredded. Facilities that reclaim refrigerant this way must still follow the recovery-level requirements.
