Phase-out Plan for CSE SR-100 SCSRs used in Mining Applications |
|---|
MSHA has issued PIB 12-09 to alert the mining industry about the results of a National Institute for Occupational Safety and Health (NIOSH)/MSHA study to evaluate the oxygen starter system on the SR-100 Self-Contained Self-Rescuer (SCSR), in which SR-100 oxygen starters failed to operate in 5 out of 500 units tested. MSHA and NIOSH agree that action is needed to assure the safety and health of miners, and that the SR-100 SCSR must be phased out of use in a timely and orderly manner. In addition, NIOSH has determined that the manual start procedure for the SR-100 should only be used as a last resort. The manufacturer's manual start procedure (a.k.a. the Cold Start procedure), is more difficult to activate and it may take more time for the SR- 100 SCSR to generate sufficient oxygen to allow for a rapid escape. MSHA wants to assure that miners are trained to know what to do if they have a problem starting their SR-100 SCSR.
