Extended Life SCBA Tanks (30 year) Most SCBA EL tanks started coming out in the USA around 2008
Here is a doc I found from MSI that I had to explain how 30 year bottles work.
RE: 30 Year Cylinders Dear Valued Channel Partners, This letter is to clarify some potential confusion in the market place regarding the life expectancy of SCBA cylinders. It has come to our attention that Scott Safety recently introduced the Scott Extended Life (EL) 30-Year Life Cylinder, which claims to provide for up to a thirty year life expectancy. That life expectancy, however, is currently not without the need for retesting and re-approval during the life of the cylinder. Specifically, the extended life cylinders have been approved by the DOT under Special Permit DOT-SP 14232. Through this process, the cylinder is approved to a fifteen year life cycle. In year fifteen, the cylinder is required to pass additional testing to ensure the integrity of the cylinder. If the cylinder passes this required test, it can remain in service for an additional fifteen years. Luxfer Gas Cylinders, the current manufacturer of the thirty year cylinder, informs us that to date, no cylinder manufactured under DOT-SP 14232 has been approved for service life longer than fifteen years. This is due to the fact that these cylinders have not yet reached the fifteen year mark where their service life will be eligible for extension. Simply put, although these cylinders have been designed to exceed the fifteen year life cycle, approval for use beyond the initial fifteen years will be dependent upon the results of additional testing that is yet to be conducted. Additionally, we note that the extended life cylinders are heavier than those offered by MSA. MSA continues to provide lightweight (up to 2.8lbs or 21.7% lighter than the EL 30) field proven carbon cylinders. These cylinders are designed to withstand the rigorous firefighting environment faced each day, while reducing the weight burden and overall fatigue experienced by the firefighter. The acquisition cost of these extended life cylinders can be over 20% more than traditional the carbon-fiber wrapped cylinders
We hope that this clarifies any misperceptions or confusion with respect to the life cycle of SCBA cylinders. Exceeding our customers’ expectations remains a priority for MSA and we will continue to evaluate opportunities to expand our product offering. Thank you for your continued support. Should you have any further questions, comments, or concerns please don’t hesitate to contact me. Sincerely, Shane Bray Product Manager - SCBA
