Safety Advisory: Retesting of Cylinders Without Calibration of Test Equipment

Safety advisory notice.

This is to notify the public that RSPA is investigating BKC Industries, Inc., 2117 Will Suitt Road, Creedmoor, NC 27522 for the marking of DOT cylinders and/or tube trailers without calibrating its test apparatus. RSPA has determined that, between September of 1998 and October of 2001, BKC Industries, Inc. (BKC) apparently marked and certified an undetermined number of cylinders and/or tube trailers as having been properly tested in accordance with the Hazardous Materials Regulations (HMR), when the cylinders and/or tube trailers were tested using equipment that was not properly calibrated. Part of performing a proper hydrostatic retest as set forth in the HMR is the calibration process. A hydrostatic retest and visual inspection, conducted as prescribed in the HMR, are used to verify the structural integrity of a cylinder. If the hydrostatic retest and visual inspection are not performed in accordance with the HMR, a cylinder with compromised structural integrity may be returned to service when it should be condemned. Extensive property damage, serious personal injury, or death could result from rupture of a cylinder. Cylinders that have not been retested in accordance with the HMR may not be charged or filled with compressed gas or other hazardous materials.
