Luxfer Gas Cylinder Safety Alert
On May 1, 2006 the U.S. Department of Transportation posted
a notice in the Federal Register concerning a small group of Luxfer
composite cylinders that may not have been properly autofrettaged and/or
hydrostatically tested by a third-party inspector, Arrowhead Industrial
If your department has any of the listed cylinders in the Federal notice,
you must discontinue use of the cylinders and return them to Arrowhead so
that autofrettage and hydrostatic tests can be completed before their next
Luxfer has verified that the cylinders are safe based on thorough testing,
detailed engineering analysis and data collected from many cylinders already
recovered from the affected group. However, departments are legally required
to comply with the DOT mandate.
