EPA Section 608 Universal Certification ExamType I (Small Appliances)Medium
A technician is transporting a recovery cylinder containing recovered R-410A from a small appliance. What is the maximum fill level for this recovery cylinder to prevent overfilling and ensure safety during transport?
- A60% by weight
- B80% by weight
- C80% by volume
- DVisual inspection to ensure space for expansion
Show answer & explanationAnswer & explanation
Correct answer: B. 80% by weight
DOT regulations and industry best practices require recovery cylinders to be filled to a maximum of 80% of their capacity by weight. This allows for liquid expansion due to temperature changes and prevents dangerous overpressurization.
Why the other options are wrong
- A. 60% by weight is too conservative; 80% is the standard maximum.
- C. 80% by volume is incorrect; cylinders are filled by weight.
- D. Visual inspection is insufficient; cylinders must be weighed to ensure proper fill level.
Recovery Cylinder Fill Limit
Recovery cylinders must not be filled beyond 80% of their gross weight capacity to allow for liquid expansion due to temperature changes and prevent dangerous overpressurization.
- Applies to all recovered refrigerants.
- Measured by weight, not volume.
- Prevents cylinder rupture.
- Ensures safe transportation and storage.
Memory trick: Eighty percent by weight keeps the cylinder safe and tight!
