CSB Publishes Update for Investigation of Fatal Explosion at Givaudan Facility

Yesterday the Chemical Safety Board (CSB) announced that it had published an investigation update for the explosion at the Givaudan Sense Colour facility in Louisville, KY that occurred on November 12th, 2024. That report describes the overpressure situation that led to the catastrophic failure of a reaction vessel, killing two operators and seriously injuring three other employees.

The report outlines the additional areas that the CSB is continuing to look at in their investigation:

• Testing the raw materials to identify potential reactive hazards,

• Analyzing the batch reactor relief system,

• Reviewing process data and process conditions leading to the incident,

• Further analyzing the recovered vent valve and actuator,

• Evaluating emergency response efforts, and

• Analyzing the building design

The report includes photographs of large pieces of the reaction vessel that were found in the residential area surrounding the facility. There were no reports of off-site injuries.
