Lightning, electrical 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. 

Fires may be started by one or several of die following so-called "common fire hazards matches and cigarets, rubbish (spontaneous ignition), locomotive sparks, mechanical spartks, friction, open-flame devices, heating appliances, electric wiring and equipment, static electricity and lightning. The primary object of fire prevention and extinction is to avoid loss of life and personal... 

Electrical hazards high voltage, high current electricity, lightning, electrical spark and arc. 

I-3.6.2 Electronic control, monitoring, and hydrogen gas measurement equipment shall be properly grounded and isolated from piping to help prevent overpressure/ accidental shutoff situations caused by equipment failure due to lightning strikes and electrical transients and to prevent safety hazards caused by fault currents. Electrical isolation equipment for corrosion control purposes should not be installed in buildings unless specifically designed to be used in combustible atmospheres. 

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... 

Also in the past 10 years or so sophisticated lightning locating equipment has been installed throughout the world. For example, all ground flashes in the U.S. are now centrally monitored for research, for better overall weather prediction, and for hazard warning for aviation, electric utilities and other lightning-sensitive facilities.
