Initially, the objective of this contract was to develop a pwscsr (sr-80) that could meet newly proposed criteria (that were not as difficult as 30 cfr 11) and that would be less than twice the volume and weight of a filter self-rescuer. The sr-80 met this objective. Consequently, the original contract was extended to develop a pwscsr that would meet existing 30 cfr 11 criteria within the same volume and weight constraints. This resulted in the development of a pwscsr (the sr-100) that received NIOSH/MSHA approval (tc-239). This report presents a historical discussion of the design and development of the sr-100. The technical parameters and the test results of NIOSH/MSHA 30 cfr 11 certification are also presented. All see publication op 214-91
