CSE SR-100 SCSR Units Alerts
Labor Department's MSHA issues user notice regarding SCSR units - Phase-out of CSE SR-100 breathing devices in underground mines to begin immediately (4/26/2012)
The U.S. Department of Labor's Mine Safety and Health Administration today announced that mine operators must immediately begin phasing out the use of SR-100 self-contained self-rescuers manufactured by Pittsburgh, Pa.-based CSE Corp. The announcement, made in conjunction with the department's Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health, was prompted by the April 13 NIOSH report of a joint NIOSH-MSHA investigation that determined the units do not conform to safety requirements. Self-contained self-rescuers are portable devices that, in the event of an emergency, can provide underground miners with up to 60 minutes of breathable air.
CSE SR-100 SCSR Units with Difficult to Remove Top and Bottom Covers
On November 5, 2010, MSHA and NIOSH alerted the mining community that some SR 100 units were discovered with end covers that can be extremely difficult to remove, particularly units manufactured between October 2008 and December 2008. MSHA estimates that there are approximately 5,400 SCSRs at active mines that may be affected.

CSE has initiated a retrofit program for all SCSRs manufactured between October 2008 and December 2008.
CSE SR-100 Starter Oxygen Cylinder Investigation
On December 7, 2009, the National Institute for Occupational Safety and Health (NIOSH) and the MineSafety and Health Administration (MSHA) opened the first of two investigations into the performance of the oxygen starter assembly on the CSE SR-100 self-contained self-rescuer (SCSR). During NIOSH tests, the oxygen startup cylinders in two SR-100 units failed to release a sufficient quantity of oxygen.
The CSE User Notice (Revised-some text bolded) states that if a breathing bag on an SCSR does not inflate, a miner should don another SCSR. If a second SCSR is not available, a miner should use the manual start procedure.
Second CSE User Notice - CSE has progressed in its investigation. Until the root cause can be identified, the potential for start-up oxygen cylinders to fail may extend to any field deployed unit, and not just the serial numbers that were previously identified. (Added 05/11/2010)
