NIOSH Testimony on Safety Standards for Underground Coal Mine Ventilation by R. W. Niemeier, August 19, 1988.
NIOSH 1988 Aug:3 pages
This testimony concerns the Mine Safety and Health Administration's (MSHA's) proposed rule on safety standards for underground coal mine ventilation. These post hearing comments are given in support of the comments and testimony previously submitted by NIOSH. These comments specifically concern opposition to prohibiting flame safety lamps and additional evidence and comments in support of NIOSH's previously stated opposition to the use of belt haulage entries as intake air courses. The flame safety lamp offers a number of ergonomic and psychological advantages over presently available continuous reading methane and oxygen monitors. It has a long history of reliable performance in the mines. A flame safety lamp can become an explosion hazard if improperly maintained or carelessly operated. The effect of ventilation rate on flame propagation and fire intensity of conveyor belts and dust dispersion are discussed in relationship to the use of belt haulage entries as intake air courses.
