MSHA PROGRAM POLICY MANUAL VOLUME V 77.206 Ladders; Construction; Installation and Maintenance The phrase "wooden members" in Paragraph (b) includes the side members and rungs of ladders. The words "used regularly" in Paragraph (c) mean, if the ladder is used for any regularly scheduled purpose regardless of the time interval. Paragraph (c) also states that backguards are required on all steep or vertical ladders that are more than 7 feet in height. This requirement in Paragraph (c) cannot be used to cite ladders on mobile equipment or for step ladders and vertical ladders that are not secured at a fixed location. 77.207 Illumination The inspector should also consider the quality of light in providing a safe working environment. Attention should be given to glare, diffusion, and direction of the light. In areas where moving equipment is present, it is necessary to have the general working area lighted in order to provide sufficient illumination. An area may be illuminated by fixed lighting, machine-mounted lights, or portable lights. 77.208 Storage of Materials It is not the intent of Paragraph (b) of this section to require valve covers on well secured intermittently used compressed gas cylinders in occupied shops and designated repair areas. However, the valve should be closed promptly after each period of use. Paragraph (e) permits the transportation and storage of compressed gas cylinders with recessed valves without additional protection. 77.211 Draw-off Tunnels; Stockpiling and Reclaiming Operations; General The requirements of Paragraph (a) of this section may be used as a factor in making a determination as to the need for a ventilation fan. However, it does not provide the authority to require a fan if satisfactory ventilation can be achieved by other means. Paragraph (b) does not require installation of a methane monitor. 77.212 Draw-off Tunnel Ventilation Fans; Installation This section does not require the installation of a fan to ventilate a draw-off tunnel; however, it does regulate the installation if used. 77.213 Draw-Off Tunnel Escapeways This section applies to any tunnel of sufficient length in which a miner could be entrapped. The escapeway shall be provided from the enclosed end to the surface by an exit other than the existing February 2003 (Release V-33) 163
MSHA PROGRAM POLICY MANUAL VOLUME V tunnel. "Equivalent size" means that the smallest dimension in the escapeway from draw-off tunnels shall be no less than 30 inches. 77.214 Refuse Piles; General A "safe distance," as used in Paragraph (a) of this section, should be at least 300 feet. Any proposal to construct a refuse pile within 300 feet should be reviewed by the District Manger. "Fenced or otherwise guarded" as used in Paragraph (d) means a gate or other similar barrier across the entrance or exits to and from the refuse pile. 77.215 Refuse Piles; Construction Requirements Paragraph (e) does not prohibit the operator from constructing a valley-fill type refuse pile, side hill refuse pile, etc., provided the operator installs hydraulic structures which will pass runoff from the affected watershed either around or under the refuse pile. The 100 year six-hour frequency storm should be used to determine the size of the hydraulic structure(s) used to accommodate surface runoff. Paragraph (g) does not prohibit the operator from storing coal on a refuse pile in the form of a temporary stockpile. 77.215-1 Refuse Piles; Identification This section does not specify a minimum or maximum size for the identification marker, nor for the letters/numbers used on the identification marker. 77.215-2 Refuse Piles; Reporting Requirements The USGS topographic map, required by Paragraph (b)(2), should be legible of sufficient size to indicate the drainage area affecting the refuse pile. The nearest landmarks or communities should also be indicated. Information, required by Paragraph (b)(3), should contain, as a minimum, the initial starting date of the pile (if known), foundation preparation (if known), material transport and handling (aerial tram, conveyor belt, truck haulage, etc.), approximate size(s) of refuse material, compaction equipment that had been used or is being used, and the lift thickness of the refuse material being placed. Paragraph (b)(6) requires the operator to furnish information regarding diversion ditch size, decant pipe size, and any other hydraulic structure being used to pass water around or under a refuse pile in a permanent manner. Under paragraph (b)(8), the operator shall submit revised reporting requirements if there are any significant changes February 2003 (Release V-33) 164
