(iv) being transported to a place of storage or use by a licensee, a certified blaster or other designated person who has lawfully acquired such explosive materials.


(2) Except as otherwise provided by this Part (rule), no indoor facility for the
storage of explosives shall be located in a residence or dwelling.

(b) Magazine locking. All magazines and all enclosures used for the storage of explosives shall be kept locked at all times except when opened by the employer, his authorized agent, the certified blaster or other designated person under the supervision of the blaster for the purpose of placing explosives therein, removing explosives therefrom, inspection or inventory of the contents of such magazines or enclosures. Locking systems installed in magazines shall comply with the requirements of this Part (rule).

(c) Access to explosives. No person unless duly authorized by the owner of the explosives or a certified blaster shall have access to or enter any magazine or explosives storage enclosure. Detonators or other explosives when removed from magazines shall not be left unguarded where children or other unauthorized persons may have access to them.

(d) Magazine inventory and inspection.

(1) Inventory.  (i) A running inventory of each magazine containing explosives shall be made at the end of each day during which blasting operations are conducted or whenever the magazine is opened for any purpose.

Exception: Such daily inventory is not required for any magazine opened only for the purpose of an inspection by the commissioner.

(e) Smoking and open flames. No person shall smoke or carry open flames, lighted objects or other spark-producing devices in or within 50 feet of any magazine containing explosives nor within 50 feet of any other explosives. This subdivision shall not be construed to prohibit the lighting of fuses for the purpose of blasting.

(f) Marking explosives. (1) Explosive containers. No person shall own, possess, store, sell or use, or authorize or permit the use of explosives unless the original package, case or container is clearly marked so as to designate the kind and grade, the manufacturer and the location, date and shift of manufacture of such explosives. The date of manufacture and shift of manufacture may be in code, provided that the key to such code shall be filed with the commissioner. All cases containing explosives for underground use shall be clearly marked with the fume classification of its contents. No explosives, other than those in fume classes 1, 2 or 3 shall be used in confined spaces.

(h) Detonator requirements. No detonator shall be sold or used unless its initiating power, as measured in the TNT-iron oxide insensitive powder test, appended hereto [see Appendix A-11, infra] and made part hereof, is at least equal to a detonator containing one gram of a mixture of 80 percent mercury fulminate and 20 percent potassium chlorate.

(i) Destroying explosives. Explosives which have deteriorated, have been damaged so as to be unfit for use or are unwanted shall be destroyed in a safe manner only by a certified blaster, a person duly licensed pursuant to section 458 of the Labor Law or by the commissioner. This provision shall not prohibit reprocessing of explosives by the manufacturer thereof.

(j) Magazines for detonators. Detonators shall be stored in separate magazines and no other explosives, materials or tools except safety fuse, wooden wedges and wooden or fibre mallets may be stored in such magazines.

(k) Magazines for all other explosives. All explosives, other than detonators, shall be stored in separate magazines devoted exclusively to such explosives in accordance with the provisions of this Part (rule).
