§ 33.251. Safety check on employes.

 (a)  It is prohibited to allow one man to load, cut load, or timber alone in a cavern. Nothing in this subchapter shall be construed to prohibit a workman from working alone in a room at these tasks, if other workmen are present in adjoining working places. The cavern superintendent or foreman shall insure that this subsection is complied with.

 (b)  The contractor or superintendent of each cavern shall provide a suitable method of keeping a check on the men entering and leaving the cavern. The cavern superintendent, or foreman shall make sure both that all employes are safely out of the cavern before blasting and at the end of each shift.
