Okla. Stat. tit. 45 § 524
The oiling or greasing of cars inside of the mines is strictly forbidden, unless the place where said oil or grease is used is thoroughly cleansed once every day to prevent the accumulation of waste oil or grease on the roads or in the drains at that point. Not more than one (1) barrel of lubricating oil shall be permitted in the mine at any one time. No explosive oil shall be used or taken into the mines for lighting purposes except when used in approved safety lamps, and oil shall not be stored or taken into the mines in quantities exceeding five (5) gallons. Only pure oils, as free from smoke as pure animal oil shall be sold or used for illuminating purposes in any mine. Any person selling for use in mines, or any person using, explosive or impure oils in any mine contrary to this section, shall be punished by a fine of not less than Fifty Dollars ($50.00) nor more than Two Hundred Dollars ($200.00), or imprisonment in the county jail not to exceed thirty (30) days, or both such fine and imprisonment. For special convenience, the operator shall keep on hand a supply of pure oil for illuminating purposes, to comply with the requirements of this section, when requested to do so by a majority of the miners working therein.
