Every person who has explosives and detonators in a mine, shall keep same in separate wooden boxes securely locked, and such boxes shall be kept at least ten feet from the tracks in all cases where room at such a distance is available, and out of the direct line of blasting. If not kept in separate boxes, they may be kept in the same box if separated by at least a four inch hardwood partition or the equivalent.
