W.\nWashington, D.C. 20036-4919\nDear Mr. Trojak:\nThis is in response to your letter and subsequent telephone conversation with Sandra Webb of my staff\nrequesting clantication of the requirements in § 173.34 for marking the tare weight on a cylinder under\nthe Hazardous Materals Regulations (HMR; 49 CFR Parts 171-180). I regret the delay in responding\nto your letter and hope it has not caused you any inconvenience.\nThe requirement was recently moved in a final rule published on August 8, 2002 under RSPA Docket\nHM-22OD; 67 FR 51652 to § 173.301(b). Your specific question is paraphrased and answered\nbelow.\nQ:\nIf the cylinder passes inspection and requalification, can the approved testers mark the new tare\nweight to the right of the original tare weight on the cylinder?\nA:\nThe answer is yes. Additional information may be marked on the cylinder provided it does not\naffect the required markings prescribed in § 178.35(1) and the applicable specification as\nspecified in § 173.301(b). However, we recommend that you stamp one diagonal line through\nthe obsoleta, original tare weights), if present, so that it is still legible for future reference.\nI trust this satisfies your request. Please contact us again if we can be of further assistance.\nSincerely,\nMasa\nSusan Gorsky\nSenior Transportation Regulations Specialist\nOffice of Hazardous Materials Standards\n\n<<<PAGE 2>>>\n\nTHE CHLORINE INSTITUTE, INC., 2001 L STREET, N.W., WASHINGTON, D.C. 20036 - 4919\n202-775-2790\nWebb\nFax 202-223-7225\n$ 173.34 (e)\nhttp://www.CL2.com\nStephen R.

Our members\nrepresent over 99% of all U.S. chlorine production and 90% of the chlorine packaging plants.\nMy questions concern cylinder requalification. CI has been approached by several\nmember companies concerning tare-weight stamping on chlorine 3A and 3AA cylinders.\nRSPA refers to Compressed Gas Association (CGA) Pamphlet C-6 in their regulations\nfound at 49 CFR §173.34(e). Pamphlet C-6 states on page 6, section 3.2.1.1 that a cylinder with\na tare weight loss of five percent or greater is required to be rejected for service. If the cylinder\ntare weight loss is ten percent or greater, Pamphlet C-6 and 49 CFR 173.34(e) both state that the\ncylinder must be condemned and removed from service. If the loss is five percent or greater, but\nless than ten percent, the CGA Pamphlet states that the cylinder must be inspected and\nrequalified by hydrostatic testing. The questions I received are regarding cylinders that pass\nthese inspections and requalifications.\n1.\nIf the cylinder passes inspection and requalification, can the approved testers\nmark the new tare weight to the right of the original tare weight on the\ncylinder? The reason for requesting this ability to mark the cylinder with the new\ntare weight is due to the following safety concerns!\na)\nPackagers do not want to overfill the cylinders and the tare weight is\nneeded to prevent this;\n* \"\n:\n...%\n*****\n:**\n* *\n•24*\nА Анороженя СлАя\nPRATARA ARROGAN\n\n<<<PAGE 3>>>\n\nMr. Edward Mazzullo\nDirector for Hazardous Materials Standards\nU.S. Department of Transportation\nApril 30, 2002\nPage 2\nThough the cylinder passed requalification, if the cylinder continues to\nlose weight, packagers need to know the original tare weight to make sure\nit is retested or condemned if the tare weight decreases below either of\nthese two established percentage levels.\nPlease contact me if you have any questions at: 202-872-4731 or by e-mail:\ngtrojak@CL2.com\nSincerely,\nF.
