3-Day Class with Field Tour:

Understanding the NFPA-780 Lightning Protection System


Class attendees will learn about the nature of lightning, including how it strikes buildings and structures and how lightning currents penetrate into building power, telecommunications, data and signal lines. Attendees will learn about approved designs for protection of communications, electrical, explosives and nuclear facilities, including air terminals, grounding, bonding and shielding subjects.

The course also covers practical aspects of personal lightning safety; transient overvoltages protection of electrical and electronic equipment; lightning detection devices; and hands-on use of field testing equipment. Relevant civilian and military lightning protection codes are discussed. Students are presented with lightning protection problems to discuss and to solve.

Who Should Attend

This non-technical course is taught by the National Lightning Safety Institute (NLSI). It is designed for responsible persons in explosives, fire safety, and industrial hygiene; architects; electrical, industrial and mechanical engineers; and all levels of supervisory personnel.

There are no academic prerequisites for attendance. Useful but not essential backgrounds include: 1) engineering or technical fields; 2) risk management, industrial hygiene, fire or safety; 3) loss control or hazard analysis; 4) facilities and building management; 5) explosives. If lightning defenses, protection and safety are on your radar screen, this education program will help.


A course examination is given. Class graduates will receive NLSI's Certificate of Completion attesting to completion of the workshop, upon request. Three (3) continuing education units (CEUs) are awarded to graduates.

Class Logistics

Classes are held at locations around the country and overseas; they are typically scheduled from 7:30 a.m. to 4:30 p.m. Tuition is $995 per person. Classes tailored to specific industries and problems, such as explosives, refineries or telecommunications, can be arranged.

Classes are informal, with frequent question-and-answer dialogs. Class size is limited to 20 attendees to allow for good interaction.

Examples of lightning protection systems based on 17 years of experience are part of the lesson plan. Texts and other documents provided for students include the comprehensive, 242-page NLSI book, Lightning Protection for Engineers, plus the most recent NFPA-780, USAF/USA/USN, DOE, NASA or other relevant codes/standards.s
