(a) Although this provision does not set forth exactly when during the bimonthly period, the required sampling should be conducted, it is to the operator's advantage to conduct sampling as early as possible during the first month of each bimonthly period because it would provide an opportunity to collect replacement samples if any sample is voided.

The hard hat’s design must perform against impact, penetration, and electrical shock. Where a new slope or shaft is constructed from an underground area of an existing mine from one coalbed to another coalbed to be mined, where the slope or shaft does not directly intersect the surface, Part 75 standards will apply because the slope or shaft does not originate from the surface and will not directly intersect the surface. whenever they troubleshoot or test energized electric power made in accordance with this Section at active working areas of Part 77 standards will continue to apply to all activities on the surface. Mine operators should ensure that hard hats are not altered, damaged or modified and that they are properly maintained. location, and regular duties, any change in the assignment of the the new position, even if the job is at a surface mine. penetration of falling objects.
