Abstract
This testimony offers several comments on several specific provisions of the proposal from OSHA for underground construction. The OSHA proposal will permit descent speeds for cages and skips for up to 600 feet per minute in shaft sinking operations, provided that the cage or skip is working in guides with safeties functioning. OSHA states also that the maximum travel speed for a guide rope system would be 160 feet per minute. The wording allows the conclusion that travel speeds could be permitted up to 200 feet per minute for systems not using guides and safeties regardless of lower designed travel speeds for a particular system such as guide ropes. NIOSH recommends additional amendments to the sections to cover the limitation placed on travel speeds. Methods and means of controlling fires within underground construction areas are also considered.
