Subject: CSE SR-100 SCSR – Notice of Iinformation. Joint Investigation – CSE Corp SR-100 Self-Contained Self-Rescuer (SCSR)
The National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety & Health Administration (MSHA) have opened a joint investigation concerning a problem that CSE Corp. has identified concerning its SR-100 Self-Contained Self-Rescuer (SCSR).
During a routine quality control test using a breathing simulator, CSE discovered that one SCSR delivered less than expected oxygen. Further analysis revealed up to one percent of the units in this lot may have oxygen starter problems. A total of 4071 units shipped from this lot may be affected. NIOSH and MSHA have requested CSE Corp. provide the serial numbers of affected units and the names of operators who purchased them.
Mine workers need to be informed that if a SCSR does not inflate its breathing bag, a miner should immediately don another SCSR. Only if a second SCSR is not available, should a manual start procedure be attempted.
Operators should make backup SCSRs available to all underground workers.
The MSHA home page (WWW.MSHA.gov) will contain further information.
