Lightning and the hazards

FPN No. 1) It is important that the authority having Jurisdiction be familiar with recorded industrial experience as well as with standards of the National Fire Protection Association, the American Petroleum Institute, and the Instrument Society of America that may be of use in the classification of various locations, the determination of adequate ventilation, and the protection against static electricity and lightning hazards. 

If electric detonators are obtained without a device for shorting the metal case to the lead wires, they are to be removed from their con tainers and immediately wrapped with aluminum foil. Personnel, equipment, and the detonator itself must be grounded during the handling of items whose lead wires are not shorted to each other or to the metal case RF Energy, Weapons and Lightning Hazards... 

To simulate lightning strikes, the researchers used a 6-million-volt generator to shoot big arcs into the liquid-hydrogen containers. Again, there was ignition but no explosion. The data indicate, Tippert concluded, that the hazards associated with TH2 utilization in combat aircraft may be less severe than those with JP-4, and therefore it is recommended that LH2 should not be disregarded as future alternate fuel for military as well as commercial aircraft. ... 

If a warehouse site is prone to exposure from one or more natural perils, design features may be incorporated which mitigate the hazards. Damage potential from earthquake, flood, lightning or windstorm/hurricane may thus be reduced or eliminated. The design and construction features discussed in this section can be applied to new, and in many cases, existing facilities.
