Ref. No.: 11-0103

Dear Mr. Van Schoick:

This responds to your letter requesting clarification of the Hazardous Material Regulations (HMR; 49 CFR Parts 171-180) applicable to fluorine. Specifically, you ask whether the closure requirements in § 173.40(c) apply to cylinders containing fluorine.



The answer is yes. As specified in § 173.301(c), cylinders containing toxic gases and toxic gas mixtures meeting the criteria of Division 2.3 Hazard Zone A or B must conform to the requirements of §173.40. While the Hazardous Materials Table references § 173.302 for non-bulk packaging requirements for fluorine, this does not except cylinders containing fluorine from the applicable requirements of § 173.40, including the closure requirements described in paragraph § 173.40(c).

I hope this answers your inquiry. If you need additional assistance, please contact the Standards and Rulemaking Division.

Sincerely,

Ben Supko

Chief, Standards Development Branch
