Session 3

Forensic Investigations of Sprinkler System Failures: The How and Why

This session will explore the critical design factors that influence corrosion in sprinkler systems an often underestimated challenge with serious implications for system longevity and performance. Muveno, specializing in suppression system design, and Olivia, a forensic engineer with expertise in material failure investigations, will guide attendees through the complexities of corrosion across different system types, including wet, dry, and foam systems.

The presentation will examine how design choices can impact corrosion rates and what adjustments can be made to mitigate these effects. It will also address what happens when corrosion is already present, offering practical approaches to managing it within existing infrastructure. The discussion will include considerations for repair, retrofit, and redesign, helping participants evaluate the most effective path forward.

Through real-world case studies, the speakers will highlight common failure mechanisms such as freezing, chemical degradation, and material incompatibility. The session will provide valuable insights into improving design, material selection, installation practices, and long-term maintenance strategies to enhance the reliability and lifespan of sprinkler systems.
