MSHA PROGRAM POLICY MANUAL VOLUME V others to whom the mine operator may deny entry, but does not include persons having the right to enter the mine. Accordingly, an operator shall not be cited for violation of paragraph (a) when a State mine inspector is observed underground without an SCSR. Citations for failure of the mine operator to provide self- contained self-rescuers shall be cited under paragraph (a) of this Section. The inspector should include in the body of the citation a statement referring to 30 CFR 75.1714-1(b) which outlines how the provisions of paragraph (a) can be met. 75.1714-1 Approved Self-Rescue Devices Under paragraph (b)(3) of this Section, MSHA will consider for approval as a self-rescue device or devices, when used and maintained as prescribed by MSHA, a combination of separate 10-minute and 60minute self-contained breathing apparatus approved under Subpart H of 30 CFR Part 11. 75.1714-2 Self-Rescue Devices; Use and Location Requirements Under paragraph (c) of this Section, the determination that wearing the self-contained self-rescuer is hazardous may be made by an individual miner or by the operator. The inspector should not issue a citation unless the person is more than 25 feet from his or her self-contained self-rescuer. The District Manager is required in paragraph (e)(1) to consider 11 factors in deciding whether to permit an operator to place a selfcontained self-rescue device more than 25 feet from a miner. In order to assist the inspector when considering these factors, the following guidelines are provided to help determine whether to permit or prohibit storage, storage distances, and storage methods and procedures. 1. Distance from affected sections to surface. If the deepest penetration of a working section is not farther from the surface than the travel distance listed in 3. below, the district manager may approve a plan for the operator to provide miners only with filter-type self-rescuers. However, when the deepest penetration of a working section is greater than the travel distance listed in 3., operators shall be required to provide self-contained self-rescuers. 1. Pitch of seam in affected sections. In pitching seams, such as encountered in anthracite mines, self-contained selfrescuers should be stored on level travelways. 2. Height of coal seam in affected sections. The height of the travelway affects the speed of travel and consequently the distance that miners may be away from stored self-contained February 2003 (Release V-33) 144
MSHA PROGRAM POLICY MANUAL VOLUME V self-rescuers. Miners generally should not be farther from self-rescuers than a distance that they can travel at a normal pace in 5 minutes. However, the time and distance can be increased or decreased after considering all factors. Miners should never be farther from self-contained selfrescuers than a distance they can travel at a normal pace in 10 minutes. The chart below should be used to convert time to the travel distance. 4. Location of escapeways. Where designated escapeways are not readily available, such as during travel in remote locations of bleeders and return airways, storage of self-contained self-rescuers should be limited to not more than 5 minutes travel time. 5. Proposed location of self-contained self-rescuers. The preferred locations for storage of self-contained selfrescuers are in the intake escapeways and accessible from more than one entry. In longwall mining sections, self-contained self-rescuer units should be stored near the face on the headgate and tailgate sides of the longwall unit. Enough self-contained self-rescuer units for all miners covered by the storage plan should be stored at both locations. February 2003 (Release V-33) 145
