Which PPE is most important when there is risk of liquid refrigerant contacting the skin?
Answer: Safety glasses and gloves
Gloves and eye protection guard against frostbite from liquid refrigerant.
Refrigerant vapor displacing oxygen in a confined space creates what hazard?
Answer: Asphyxiation
Heavier-than-air refrigerant vapor can displace oxygen and cause asphyxiation.
When refrigerant contacts an open flame, what dangerous byproduct can form?
Answer: Phosgene and other toxic gases
Refrigerant exposed to flame can decompose into toxic gases like phosgene.
A high-pressure appliance must be evacuated before disposal to ensure:
Answer: No refrigerant is vented during scrapping
Evacuating before disposal prevents illegal venting when the unit is scrapped.
Who is responsible for ensuring refrigerant is recovered from a system going to a scrap yard?
Answer: The last person in the disposal chain who recovers it
The final person handling the appliance must verify refrigerant recovery before disposal.
Mixing two different refrigerants in one recovery cylinder is:
Answer: Prohibited because the mix cannot be reclaimed
Mixed refrigerants cannot be reclaimed and must be costly destroyed, so mixing is prohibited.
