Lightning Rod Standards

Note that lightning protection systems do not prevent lightning from striking the structure but rather intercept a lightning strike provide a conductive path for the harmful electrical discharge to follow the appropriate ul listed copper or aluminum cable and disperse the energy safely into the ground.

Lightning rod standards.

Where a lightning rod poses a recognized hazard of impalement and a there is a feasible means of protection the employer is required to provide that protection. We examine lightning protection system components and completed installations for compliance with ul s internationally recognized standards for lightning protection systems ul 96a or other recognized national standards such as or nfpa 780.

In a lightning protection system a lightning rod is a single comp. A lightning rod or lightning conductor is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. Lightning standards our lps france design offices technicians perform all technical studies according to french and international standards in force.

Lightning rods and the accompanying protection system are designed to protect a house or building from a direct lightning strike and in particular a lightning initiated fire. The most complex projects can be realized thanks to a deep knowledge of the different standards by our services. Many lightning victims are caught outside.
