Certifications

The Lightning Protection Institute promotes and supports the proper installation of a lightning protection system as outlined in the NFPA 780.  To ensure the integrity of a lightning protection system, proper installation and maintenance procedures should be followed.  This process includes utilizing individuals who are specifically certified in the lightning protection industry.

LPI Certified individuals include: Journeyman Installers (JI), Master Installers (MI), and Master Installer/Designers (MID).  The LPI certifications include several requirements including field experience and testing for each qualification level.  The LPI certification tests have gone through multiple phases of development.
