| ENS 41090 | 1 October 2004 15:00:00 | 10 CFR 21.21 | Cracks/Fissures in Power Air Purifying Respirators (Papr) Motor/Blower Assembly Casings | Exact content of notification: Battelle is notifying NRC of a potential defect as from the manufacturer concerning the MSA equipment provided Model MM2K PAPR motor/blower assembly (Part 10022695). After limited field use at its West Jefferson, Ohio site noticeable cracks/fissures developed on some of the motor/blower casings. The manufacturer of the equipment, MSA, has been notified of the problem and several of the cracked/fissure units have been returned to MSA for testing in early September. Battelle discontinued use of the MSA Model MM2K PAP'R in mid September as a result of the observed equipment cracks/fissures at its West Jefferson, Ohio site. Describe the event: We have been experiencing noticeable cracks/fissures of some of our MSA brand MM2K Powered Air Purifying Respirators (PAPR) motor/blower assembly casings (Part #10022695). We have not experienced any break through of the casings tied to employee exposure as evidenced by our In place personnel monitoring programs. Our original note of the circumstance was on August 25, 2004 during the re-use inspection process of the MSA MM2K PAPR by the Respiratory Protection Supervisor on site. We have field verified that our respirator cleaning and use processes are adequate and in line with the manufacturer recommendations. We again experienced a similar crack/fissures Issue with a different order of MSA MM2K PAPR motor/blower assemblies by a different vendor ordering from a different lot number in early September 2004. We have discontinued use of the MSA MM2K PAPR on site in mid September as a result of the issues we have had and have supplied MSA with several of the cracked/fissured MM2K PAPR motor/blower assembly casings for testing at their facility In Pennsylvania. MSA Is working on a solution for the identified issue. |
