Does anyone know if there are any bonding and grounding rules related to buildings used for the storage of dynamite?

The buildings are without any supply of electricity. My first thought would be concerning static electricity and/or lightning, and how they may become a problem.

I just found this section in NFPA 77, Static Electricity:

9.5 Explosives.

Most explosives and materials used as solid propellants contain enough oxidizer to sustain an explosive reaction without any outside contribution. These materials typically are sensitive to static electric discharge and can be extremely hazardous to handle if suitable precautions are not taken. In addition to the recommendations contained in this recommended practice, the following documents should be consulted for more specific information:

(1) NFPA 495, Explosive Materials Code

(2) NFPA 498, Standard for Safe Havens and Interchange Lots for Vehicles Transporting Explosives

(3) NFPA 1124, Code for the Manufacture, Transportation, and Storage of Fireworks and Pyrotechnic Articles

(4) NFPA 1125, Code for the Manufacture of Model Rocket and High Power Rocket Motors

(5) U.S. Department of Defense Standard 6055.9, Ammunition and Explosive Safety Standards

(6) U.S. Department of Defense Standard 4145.26M, Contractors’ Safety Manual for Ammunition and Explosives

(7) IME Safety Library Publication No. 3, Suggested Code of Regulations for the Manufacture, Transportation, Storage, Sale, Possession, and Use of Explosive Materials

(8) IME Safety Library Publication No. 17, Safety in the Transportation, Storage, Handling, and Use of Explosive Materials

During World War II, a retired Vice President of Underwriters Laboratories, Herbert G. Ufer, developed it for the U.S. Army. Igloo shaped bomb storage vaults were being built, and possible static and lightning induced detonation problems were of concern
