Missouri Revised Statutes Title XVIII. Labor and Industrial Relations § 293.270. Storage of over daily supply of explosives in mine prohibited

No person, partnership or corporation, nor any agent of any such person, partnership or corporation, engaged in mining for coal, shall permit any blasting powder or any high explosive containing nitroglycerine, to be stored in any such mine; provided, however, that nothing in this section shall be construed to prevent the storing in any such mine of sufficient blasting powder or other high explosive to meet the estimated requirements of such mine during the succeeding twenty-four hours; and provided further, that such temporary supply shall not be kept at any place within such mine, where its accidental discharge would cut off the escape of miners working therein.
