Long Term Field Evaluation Concept

The Long-Term Field Evaluation (LTFE) program for self-contained self-rescuers (SCSRs) for miners was initiated more than 20 years ago by the U.S. Bureau of Mines. The objective for the LTFE program is to obtain data to determine the expected performance characteristics of SCSRs used in the mining industry. LTFE program results based on scientific principles can provide useful information to monitor expected SCSR performance and assess possible degradation due to the physical stresses of in-mine use. Of utmost concern is the successful performance of any SCSR that passes its inspection criteria specified by the manufacturer. It is such apparatus that must be relied upon in an emergency. A meeting was held on March 22, 2007 in Moon Township, Pa and that information can be found below.
