Aluminum scuba cylinders in oxygen-enriched and oxygen service – are Luxfer scuba cylinders ready for oxygen service when they leave the Luxfer factory?
New Luxfer scuba cylinders manufactured from January 1, 2000, until December 31, 2004, were cleaned for oxygen service at the factory and sealed with an oxygen-compatible cap before being shipped. However, starting on January 1, 2005, Luxfer began providing oxygen-clean scuba cylinders only by special order. Unless specifically ordered “oxygen clean,” new Luxfer scuba cylinders will be cleaned for gas mixtures containing only up to 23.5% oxygen. (Of course, it will still be possible to have these cylinders cleaned for use with higher concentrations of oxygen by following the DOT-specified procedures cited above.)
