PHMSA was recently notified of the manufacture, marking, and sale of certain high pressure DOT exemption cylinders that were not tested in accordance with applicable regulatory requirements.

These cylinders were manufactured and/or distributed by Luxfer, Inc. (Luxfer), Riverside, CA. Luxfer and its independent inspection agency, Arrowhead Industrial Services, Inc. (Arrowhead), reported to PHMSA that 6,325 high pressure cylinders manufactured to the DOT CFFC and FRP-1 standards as authorized in DOT- E 10915, DOT-E 9634, and DOT-E 9894, had been shipped from Luxfer without undergoing the required autofrettage and hydrostatic tests.

In a joint effort, Luxfer and Arrowhead have retrieved 2,581 of the untested cylinders. The model numbers and serial numbers of the remaining 3,744 cylinders may be found in pages 25634 through 25639 of the Federal Register, available at: http://hazmat.dot.gov/regs/notices/sa/71fr-25633.pdf. Only cylinders with the listed model numbers and serial numbers are affected. A person with a listed cylinder should discontinue use of the cylinder and return it to Arrowhead so that the autofrettage and hydrostatic test can be completed before its next use.

Hazardous Materials Safety Administration,
