Cooling Tower Incidents and Failures

Cooling towers can be involved in Legionella outbreaks or fire events from combustible fill materials and nearby ignition sources, and failures in biocide treatment or adjacent fire suppression have escalated incidents. These investigations document the CSB's findings and recommendations for cooling tower safety.

4 CSB investigations in this database involve cooling tower as a primary or contributing equipment factor, spanning 1998–2024.
