| Title | Agreement State Report Involving Safety Equipment Failure |
| Event Description | On 2/12/04, a Niton XRF Portable Analyzer (model Xli 800 - S/N 5089) shutter failed to close when the device was placed in the off mode. The incident occurred at the Pearl Harbor Naval Shipyard in Honolulu, HI and did not involve any significant radiation exposures to personnel. The device was packaged with temporary shielding and returned to Niton for evaluation.
Niton determined that the shutter malfunction was the result of a loose set screw which connects the shutter to the motor. A component change to the Xli 800 series models was made that involves upgrading to a nylock set screw. This was the first instance of this type of failure. Instruments returned to Niton for resourcing or software upgrade will be modified in this manner to prevent shutter failure. This particular device contains a 30 millicurie Americium-241 source and is used for rapid identification and chemistry of metal alloy composition. |
