Refrigerant recovered out of small appliances has to be stored in what kind of container?
Correct Answer
A) A DOT-approved recovery cylinder that is marked for the refrigerant service being performed
Recovered refrigerant goes into cylinders built and approved for the job, which means DOT-approved recovery cylinders marked for the service. These cylinders carry the correct pressure rating, the right valve arrangement, and periodic requalification. Disposable cylinders are built to be filled once at the factory and are not approved to be refilled. Propane bottles, unmarked tanks, and anything plastic are not acceptable containers and create a genuine rupture hazard.
Why This Is the Correct Answer
A DOT-approved recovery cylinder is designed, tested, and marked for refilling with recovered refrigerant. It has the pressure rating and the valve configuration the work requires and is subject to requalification, which is why it is the only acceptable container for refrigerant coming out of an appliance.
Why the Other Options Are Wrong
Option B: Any steel cylinder that still holds pressure and has a valve in working order
A cylinder that merely holds pressure may be the wrong rating, the wrong service, or long past its requalification date. Approval markings, not appearance, determine whether a cylinder may be used.
Option C: The original disposable cylinder that the refrigerant was first shipped in
Disposable cylinders are single-use containers filled at the factory. Refilling them is prohibited and dangerous, since they are not built or tested for repeated pressurization.
Option D: A sealed polyethylene recovery bag rated for shop use
Refrigerant coming out of a small appliance is stored under pressure. No plastic bag is an approved container for it under any circumstance.
Memory Technique
Yellow top on a gray body is the recovery cylinder's uniform. Anything out of uniform stays out of the job.
Reference Hint
DOT cylinder requirements and 40 CFR 82.166 recordkeeping; recovery cylinders must be DOT-approved and marked for the service.
