National Lightning Safety Institute (NLSI) is an independent, non-product advocate of lightning safety for both people and structures:

Personal Lightning Safety means anticipating a high-risk situation and moving to a low-risk location. Result: Improved ES&H practices.

Structural Lightning Safety means using various exterior and interior defensive systems in a detailed, site-specific process. Result: Improved power quality assurance.

NLSI provides objective assistance on many kinds of lightning problems, including experience with:

• Informative classes, lectures, seminars, and  workshops
• On-site technical assessments, audits, and inspections

NLSI is an “authority having jurisdiction” (AHJ), qualified to approve, certify, and inspect equipment, installations, materials, and procedures.

As AHJ for a client, NLSI can base acceptance of a lightning protection system on compliance with NFPA or any other code or standard of practice.

We have considerable experience in the following economic sectors: aviation; communications and IT; defense, including explosives; mining; petrochemical; and power generation.

Our website provides a wealth of training materials, maps, photos, and factual details about lightning issues, written by both NLSI and other lightning experts.

NLSI's illustrated technical book on Lightning Protection for Engineers has been updated for 2009.
