System and the Components
Introduction to a lightning protection system – how a system works and what components are involved in a complete system.
*LPI Members can request a custom brochure to include their company’s projects.
Inspection
The LPI-IP is the most comprehensive 3rd Party inspection program for the Lightning Protection industry. The LPI-IP has the ISO/IEC 17020 Accreditation Inspection Body listing from ANAB, the ANSI National Board of Accreditation.
Homeowners
A lightning protection system intercepts a direct lightning strike and safely discharges the lightning current to prevent fire, structural damage, or personal injury. Systems should be designed and installed to meet national safety standards.

How Much Lightning Actually Strikes the United States?
Authors: Chris Vagasky, Ronald L. Holle, Martin J. Murphy, John A. Cramer, Ryan K. Said, Mitchell Guthrie*, and Jesse Hietanen (*LPI Member)
Knowing the reliability documented number of cloud-to-ground lightning flashes and ground contact points has significant impacts. A primary category of use for this data can be during a risk assessment for lightning protection systems in specialized applications. Other lightning-sensitive applications will benefit, including human safety and forestry.

Case Studies
YORKTOWN HOTEL - TAPESTRY COLLECTION by Hilton - York, PA
The Yorktowne Hotel, located in York Pennsylvania, is a historically significant building that was first opened in 1925. The 14-story building was completely renovated to re-open as a luxury hotel with a rooftop restaurant and bar.
ONE 22 ONE Tower - Nashville, TN
A conversation with Bonded of Texas. Through Q&A, Bonded shares with us the importance of collaboration to overcome challenges during the design and installation phases.
Hard Rock Hotel & Casino - Hollywood, FL
The Hard Rock’s signature guitar shape of the building made the design and installation of its lightning protection system challenging. Due to the complex geometry of the building, a spirit of cooperation was required to coordinate the variety of details and installation techniques.
Summit House Visitor Center - Pikes Peak, CO
The Pikes Peak Visitor Center, formerly the Summit House, stands at an altitude of 14,115 feet above sea level and can experience temperatures as low as -39.

MERLIN Low Detection Efficiency Study Results: First Two Years
Dr. Dustin Hill; Dr. Carlos Mata
Lightning Detection is more complex than previously considered. MERLIN provides continuous lightning detection and location information at the Kennedy Space Center and Cape Canaveral Space Force Station. This data is utilized to measure lightning risks for space events. Dr. Hill and Dr. Mata, of Scientific Lightning Solutions (SLS), evaluate and compare the measurement of lightning on tall structures from past and current studies. Read how their conclusions show us to be mindful of the margin of error with existing lightning detection methods.
A Detailed Analysis of Lightning Deaths in the United States from 2006 through 2022
John S. Jensenius, Jr.
Former Meteorologist with the National Weather Service for more than 41 years.
John Jensenius provides us with a detailed analysis of personal injuries due to lightning strikes. This report examines lightning fatality data from 2006 to 2022. Distinct patterns emerged in the fatality statistics in terms of the age, gender, and activity of the victims.
Performance Evaluation of Non-Conventional Lightning Protection Systems Based on NLDN Data
Dr. Carlos T. Mata; Dr. Jonathan D. Hill
The usage of non-conventional lightning protection systems (LPS) in lieu of traditional Franklin rod (air terminal) systems is a controversial subject. Here, we examine historical lightning strike-point data from the National Lightning Detection Network (NLDN) to evaluate the performance of CTS, specifically the patented Dissipation Array System (DAS), installed at two prominent facilities in the United States.
