# SUMMARY:

The National Institute for Occupational Safety and Health (NIOSH) announces the following availability of opportunity for the public to provide input regarding the draft document, “Long-Term Field Evaluation (LTFE) Program Concept.”

NIOSH is the Federal agency responsible for conducting research and making recommendations for the approval for self-contained, self-rescuer (SCSR) closed circuit escape respirators, Title 42, Code of Federal Regulations (CFR), Part 84.

                        The 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                               ( print page 13115)                            criteria specified by the manufacturer. It is such apparatus that must be relied upon in an emergency.                    

                        A copy of the draft document can be found at                         *http://www.cdc.gov/​niosh/​review/​public/​NPPTL-LTFE/​*.
