Dear Mr. Downer:
This is in response to your February 28, 2001 letter, requesting clarification on the qualification, maintenance, and use of cylinders under § 173.34 (e)(13) of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask whether a cylinder used in exclusive service for Liquefied hydrocarbon gas and Liquefied petroleum gas would include the "vapor phase" of the various gases shown in the table entries for these two groups.
The answer is yes. A cylinder used exclusively for the listed gases or mixtures including their vapor phase, and provided they are commercially free from corroding components, can be given a complete visual inspection instead of a periodic hydrostatic retest at the time periodic retest comes due.
I hope this information is helpful. Should you have further questions, please contact us.
Sincerely,
Hattie L. Mitchell
Chief, Regulatory Review and Reinvention
