Dear Ms. Bruecks:

This responds to your September 9, 2005 letter asking if a DOT-3HT specification cylinder may be used for “paintball” service and then be hydrostatically retested in accordance with § 180.209 of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-10).

The HMR provides that a DOT-3HT specification cylinder is authorized for aircraft use only and only for nonflammable gases. The HMR also prescribes the requalification requirements for DOT-3HT cylinders. In accordance with §180.209(k), in addition to the other requirements of this section, a cylinder marked DOT-3HT must be requalified in accordance with CGA C-8 pamphlet.

For reasons of safety, it is at the discretion of an authorized retester whether it will accept a cylinder for requalification and perform a hydrostatic retest on the cylinder. We do not recommend retest of such cylinders that are used in unauthorized cylinder service, and suggests that you inform your customers.

I hope this satisfies your inquiry. If we can be of further assistance, please contact us.

Sincerely,

John A. Gale
Chief, Standards Development
Office of Hazardous Materials Standards
