SUBJECT: CSE Corporation SR-100 Self-Contained Self-Rescuer
Scope
This Procedure Instruction Letter (PIL) is intended for all Coal and Metal and Nonmetal Mine Safety and Health enforcement personnel.
Purpose
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.
Procedure Instruction
Mining companies utilizing these units may need to make adjustments to provide miners with the required number of SCSRs to comply with 30 C.F.R. Part 57 and 75. Purchasing units from a different manufacturer to meet the required number of SCSRs is acceptable provided all miners have received required training on the new units. If all manufacturers of SCSRs have exhausted their inventory and mining operators cannot obtain adequate supplies, MSHA will accept purchase orders with a confirmed delivery date of 60 days. While waiting on delivery of SCSRs, MSHA coal personnel will ensure that workers on coal mining sections are provided with the required number of units borrowed from SCSR caches located the farthest outby from the working sections.
Inspection personnel are to ensure that mine operators currently using CSE Corporation's SR-100 SCSRs are informed of the May 10, 2010, user notice that states if an oxygen cylinder fails to deploy, users should obtain another SCSR. If another SCSR is not available, the manual start procedure should be used.
Authority
The Federal Mine Safety and Health Act of 1977, as amended, 30 U.S.C. § 801 et seq.; 30 C.F.R. §§§ 57.15030, 75.1714(a)(b) and 75.1714-4(a)(b)(c).
