Early Streamer Emissions (ESE) Evaluations

Mitigate risk from lightning damage and promote peace of mind with independent lightning protection system (LPS) installation inspection services from UL.

Lightning over the World Trade Center

Overview

When a traditional Franklin-based LPS is impractical, an ESE LPS installation may be a viable option. An ESE installation can enhance LPS protection for some building configurations, industrial sites, monuments or other architecturally unique structures. Each year thousands of ESE systems are installed on structures in the United States. An independent third-party inspection and validation by UL helps ensure installation compliance with standards and requirements, while providing protection and peace of mind for architects, building owners, insurance agencies, code officials, general contractors and LPS installers. 

We offer an Engineering Inspection Report for ESE systems installed in the United States using UL certified Early Streamer Emission Air Terminals (ESEAT). This LPS inspection service evaluates installations in compliance with original equipment manufacturers (OEM) specifications for ESE systems. The Engineering Inspection Report includes detailed results that UL Listed LPS Installers may share with applicable stakeholders.

Benefits

Minimize risk of significant property damage caused by lightning strikes to:

  • Reduce downtime and loss of business from lightning damage
  • Provide peace of mind that LPS installations comply with installation requirements
  • Leverage knowledge of 100 years of LPS evaluation experience.
