You stated that most carbon composite cylinders manufactured by SCI have\nan outside layer of a resin-based material (FlowCoat) added to the cylinder. Specifically, you asked if it\nis permissible to place the cylinder label containing the manufacturing standard information under this\nFlowCoat.\nThe answer is no. The marking requirements in DOT-CFFC Standard, Section CFFC-14, state that\ncylinders made in conformance with this standard and the applicable DOT exemption must be\npermanently marked (other than stamping) in the composite overwrap on the sidewall. Therefore, your\nproposed label application does not meet the requirements of the DOT-CFFC standard.\nYou may submit a request to modify the terms of the applicable exemption by providing supporting\ninformation to demonstrate that your proposed modification will achieve a level of safety at least equal\nto that established by the current standard and current exemption.\nIf we can be of further assistance, please contact us.\nSincerely,\nDelmer F. Billings\nChief, Regulations Development\nOffice of Hazardous Materials Standards\n178.35\n020295\n\n<<<PAGE 2>>>\n\n•\nStructural Composites Industries\nSCE\nHarsco\nPomona, CA 91768 USA\n325 Enterprise Place\nTelephone: 909.594.7777\nWeb: www.scicomposites.com\nFax: 909.594.3939\nNovember 13, 2002\nWebb\nVia Federal Express\n$178.35\nMr. Ed Mazzullo\nI.
