§ 33.14. Daily supply.

 (a)  When dynamite, black powder, fuse, blasting caps, electric blasting caps or detonators, electric squibs, or other explosives are removed from a magazine they shall not be stored or kept in bulk near or in the pit or quarry except when loading well holes. Any person who keeps these articles in a pit or quarry for use in work for one day shall keep them in a Class B magazine, which shall be located in a cool, dry place protected from falling or flying objects. This magazine shall be kept securely locked except in deep pit quarries. The pit foreman or the blasters, or both, shall at all times hold the key or keys to such magazines. Matches, carbide, oil, gasoline or tools, shall not be kept in the same magazine with black powder, dynamite, fuse, blasting caps, electric blasting caps or detonators, electric squibs, or other explosives.

 (b)  Nothing in this subchapter shall be construed to prohibit the opening of containers at the distribution point for the purpose of distributing the daily supply to each person requiring explosives if the daily supply is less than 25 pounds of black powder, or 50 pounds of dynamite and 50 electric blasting caps, or detonators or 100 blasting caps.

 (c)  Nothing in this subchapter shall be construed to require any dynamite, black powder, fuse, blasting caps, electric blasting caps or detonators, electric squibs or other explosives, left over from a day’s work to be transported from a Class B magazine back to the main magazine. All old explosives remaining over from work from a prior day shall be used first.

 (d)  No person shall keep more than one 25-pound keg of black powder or one 50-pound box of dynamite or other explosive at any one time in any one working place, unless more time is necessary to accomplish work for one day.

 (e)  Each person using blasting caps, electric blasting caps or detonators, or electric squibs in a pit or quarry shall keep his daily supply in a safe and dry place, if blasting caps, electric blastings caps or detonators, or electric squibs are not stored in the same magazine containing his daily supply of dynamite, black powder or other explosives. Fuse shall be kept in a cool, dry place. If more than 25 pounds of black powder or 50 pounds of dynamite is kept at one spot in a pit or quarry, blasting caps, electric blasting caps or detonators, and electric squibs shall be kept not less than ten feet away from the explosives.

 (f)  All blasting caps, electric blasting caps or detonators, and electric squibs used in work for that day in a pit or quarry shall be carried into the pit or quarry in the container in which they were originally packed by the manufacturer, except that a quantity less than one full container may be carried into a pit or quarry in a suitable container.
