Okla. Stat. tit. 45, § 45-424: Explosives - Storage, transportation, handling and use

At all said mines in this state, all explosives shall be stored

in a magazine placed far enough away from hoisting derricks to

insure their remaining intact to case of explosion. All explosives

in excess of the amount required for the work of one shift shall be

kept in such magazine. Powder other than the shifts requirements

shall not be stored in underground workings; provided, however,

where such mines are located in densely populated areas, and then

only with the permission of the deputy mine inspector, explosives

may be stored underground in a suitable place selected by the said

inspector, but in no event shall more than three (3) days normal

requirements at the particular mine be so stored underground. No

explosives shall be transported on or in any electric or gasoline

locomotive, or in the car next to these locomotives. Detonators or

caps shall not be stored or transported with other explosives.

Mechanical loading devices, first found to be safe for the miners

who work in said mine by the assistant mine inspector, and such

finding is approved by the Chief Mine Inspector, or wood-loading

sticks or tamping bars protected with copper ferrules and copper

spike must be used when loading holes. All blasting caps shall be

crimped onto fuse by regulation crimper. Powder delivered to top of

shaft shall be lowered into ground immediately. Explosives must not

be taken from any mine without the consent of the foreman in charge.

Open lights must not be used in powder magazines or detonator

magazines. Explosives stored in ground must be so stored as not to

cut off passage of men to shaft in case of explosion occurring. No

employee shall return to a drift, heading, shaft, or tunnel, or

other place where a shot has failed to explode until a period of at

least thirty (30) minutes has elapsed after firing; all failed shots

to be promptly reported to foreman by employees. No employees other

than those employed in shaft sinking shall ride any can, bucket or

hoisting apparatus carrying explosives. No shooting or blasting

shall be done from the time the man shift goes on until the man

shift goes off, except in extreme case for the protection of life.
