Okla. Stat. tit. 45, § 45-417: Dust - Water lines - Sprinkling attachments

The Mine Inspector is hereby authorized, empowered and directed

to thoroughly inspect all underground excavations in all such mines

as often as such Inspector may deem proper, for the purpose of

ascertaining or discovering in the air in any such mine or mines the

presence of dust in such quantities as shall be injurious to the

health of the employees engaged in working in such underground

excavations; and upon finding dust in the air of any such mine or

mines in quantities exceeding three hundred particles per cubic

centimeter, as shall tend to injure the health of the employees of

such mine, such Inspector shall immediately notify the operator of

such mine or mines, in writing, specifying the underground

excavation so found to contain dust particles in excessive amounts,

as aforesaid in the air thereof, and such operator of such mine or

mines shall within fifteen (15) days after receiving such written

notice, provide, install, and equip, and thereafter at all times

maintain in such mine, a water line fully equipped, and in good

serviceable working order and repair, leading up to the face of any

and all drifts where dust is produced, or so close to the face of

said drifts so that by the use of a suitable hose extension or

sprinkling attachments to be supplied by the owner or owners of said

mine, the mineral or earth in and adjoining the face of the drift or

drifts of such mine can be sprinkled or wet by water from said

pipeline; thereupon and thereafter, every person drilling, squibbing

or blasting in said mine shall keep the face, surface, and drill

holes in said drifts or drift wet or moist by the use of water from

said water line to such an extent in such a way as shall prevent, as

far as possible, any dust raising from the working of any such face,

or from the drilling, blowing, or shooting of any hole or holes; and

the ground foreman in charge of the underground workings in any such

mine or mines, so equipped with a water line, shall require all

ground or dirt after being shot or blasted to be thoroughly wet or

sprinkled to such an extent as shall prevent, as far as is

practicable any dust from arising therefrom, while the employees are

at work therein.
