LPI provides the industry self-policing testing program for Journeyman, Master Installer, and Designer Inspector Certification of members. LPI publishes this document # 175, based on NFPA 780, with additional explanatory material helpful to installer and inspector member personnel. LPI advocates use of UL as the third-party inspection authority for components according to their documents UL 96. The Lightning Protection Institute (LPI) adopts the latest edition of the NFPA 780 Standard as its reference document for system design. Some partial constructions may be available for field inspection under their “Letter of Findings” program. UL will also inspect to some other nationally recognized Standards (like NFPA 780) for fully compliant systems. Standard 96A is based on the general requirements of NFPA 780, but UL has a Standards Technical Panel (STP) to review the requirements for a more inspectable format which leads to some differences. UL has issued a “Master Label” product for systems fully compliant with their Standard UL 96A for many years. UL has inspection personnel who visit production facilities on a regular basis to verify compliance for continued use of their approved merchandise labels.įield inspection of completed lightning protection installations may also be arranged with UL through installing contractors listed in their program. The UL Standard 96 addresses the minimum requirements for construction of air terminals, cable conductors, fittings, connectors, and fasteners used in quality lightning protection systems. Product testing for lightning protection material components in the factory prior to shipment for listing and labeling is handled by Underwriters Laboratories, Inc. NFPA 780 provides the best we know today in theory and technology on protection systems tested by experienced industry professionals in a legally recognized format. The 780 document covers many specialty constructions from hazardous materials storage to boats and ships to open picnic structures, and gives recommendations for personal safety outdoors. NFPA 780 includes lightning protection for typical building construction in Chapter Four as requirements for ordinary structures. The lightning protection Standard # 780 is reviewed on a three-year cycle for updating. NFPA documents like the National Electrical Code (NEC – NFPA 70), National Fuel Gas Code (NFPA 54), and Uniform Fire Code (NFPA 1) are developed by the committee process to review acceptance of new safety information on specific fire related subjects. NFPA published its first document on lightning protection in 1904. (NFPA) publishes document # 780 titled Standard for the Installation of Lightning Protection Systems considered the national design guide for complete lightning protection systems in the United States. LPI is dedicated to ensuring that today’s lightning protection systems provide the best possible quality in both materials and installation practices for maximum safety. Most of these property losses could be minimized, if not eliminated, through the implementation of proper lightning protection for structures. Direct lightning strikes cause fire damage in excess of $200 million per year, and insurance companies pay claims in the billions of dollars associated with lightning either directly or indirectly. Lightning is the direct cause of over 50 deaths and 400 injuries each year, and it is difficult to protect individuals in exposed outdoor areas. The lightning protection industry began in the United States when Benjamin Franklin postulated that lightning was electricity, and a metal rod could be used to carry the lightning away from a building. The Lightning Protection Institute is a nationwide not-for-profit organization founded in 1955 to promote lightning protection education, awareness, and safety.
