Last November, a tragic explosion at a food-coloring facility in Louisville claimed the lives of two workers and injured three others. The U.S. Chemical Safety and Hazard Investigation Board has released new findings about the incident, shedding light on the circumstances that led to this devastating event.
The explosion occurred at the Givaudan Sense Colour plant while it was producing caramel food coloring. Investigators found that materials used in the process contributed to a runaway chemical reaction. This reaction created dangerously high temperatures and pressures that exceeded the reactor’s safe limits, ultimately causing the explosion.
According to the report, both the caramel mixture and the sugar used in the process could trigger hazardous reactions even within normal operating conditions. Specifically, the sugar likely decomposed, producing gases that built up pressure in the reactor.
The force of the blast was immense. It sent large metal pieces flying up to 400 feet, damaging surrounding homes and businesses. Residents were ordered to shelter in place as a precaution.
This facility had faced complaints from neighbors for years due to unpleasant odors. Following the explosion, it has ceased operations and is now set to be demolished.
The investigation into the incident is ongoing, and a final report will be released once the review is complete. For those interested in more details, the Chemical Safety Board has made the update available online.
