Through its quality control program, CSE Corporation identified a possible issue with a component part to its
SR-100 Self-Contained Self-Rescuers (SCSRs) involving a shipment of oxygen cylinders from its supplier. CSE is investigating the potential that the breathing bag may receive less than the optimum amount of oxygen necessary for full inflation, if the unit is started with the oxygen cylinder. Until the root cause is determined and corrected, CSE Corporation is temporarily suspending sales of the SR-100 SCSRs.
