NIOSH Testimony on Confined Spaces by R. W. Niemeier, February 28, 1992.
NIOSH 1992 Feb:5 pages
This testimony summarized the views of NIOSH concerning the development of a confined space rule for mining. Underground mining presents particular difficulties in applying a confined space definition. Most underground mine areas meet two of the three criteria of the NIOSH definition in that they have limited openings for entry and exit and they have unfavorable natural ventilation. However, the third criteria, that they not be intended for continuous employee occupancy, is not true of an underground mine. It may be feasible to use ventilation rates and atmospheric monitoring criteria as a part of the definition of confined spaces for underground mines. This testimony also discussed training of personnel required to work in or around confined spaces, as well as respirator selection and use for confined spaces.
