Okla. Stat. tit. 45, § 45-527: Precautions against dust or explosive matter

In case any entry, or room in any coal mine in this state is so

dry that the air becomes clogged with dust, the operator, owner,

lessee or agent, or whoever is operating said mine in any capacity,

shall have such entry, airway or room, regularly and thoroughly

sprinkled, sprayed and dampened with water, so that the air will not

be charged with dust, or if that be impracticable, then the dust

shall be removed from the mine and shall not be deposited in any

place in the mine where it would be again distributed in the

atmosphere by the ventilating currents. It shall be the duty of the

district inspector to enforce all possible preventative measures

necessary to maintain the safety of all persons employed in any mine

against the gathering or accumulation of any combustible matter that

is explosive in its nature, and shall cause the operator, or

whosoever is operating such mine as owner, lessee, agent, or in any

capacity, to immediately remove any such accumulated matter.
