Givaudan Ignored Warnings Before Fatal Louisville Factory Explosion
A cooking vessel failure killed at least two workers and displaced hundreds of Louisville residents after Givaudan Flavors Corporation allegedly ignored repeated employee warnings about overheating equipment at a plant that exploded once before in 2003.
On November 12, 2024, Givaudan’s Louisville factory exploded when a cooking vessel overheated and failed to vent properly, killing at least two people and injuring dozens more. Employees had warned management for days that Cooker No. 6 was overheating and told coworkers not to walk past it, but the company kept production running. The same facility had a fatal explosion in 2003 from the same type of vessel failure. Hundreds of residents were forced to evacuate and many homes were repeatedly burglarized while Givaudan allegedly failed to provide adequate security or compensation.
This wasn’t an accident. It was a choice to prioritize profit over people.
The Allegations: A Breakdown
| 01 | Givaudan employees warned coworkers about Cooker No. 6 days before the blast, explicitly telling them not to walk past the equipment because it had been overheating for several days. Despite these warnings, the cooker continued to operate until it exploded on November 12, 2024. | high |
| 02 | The Bureau of Alcohol, Tobacco, Firearms and Explosives concluded that cooking vessel No. 6 failed because it did not vent properly, causing overheating and overpressurization. Agents stated there were signs of possible maintenance issues with that equipment. | high |
| 03 | Givaudan operated the same facility that exploded in 2003, killing one employee. After that explosion, investigators found no relief device for overpressure protection, no basic process control or alarm instrumentation, and no adequate operating procedures or training programs. | high |
| 04 | An employee raised concerns with management about leaking sulfur dioxide prior to the incident and reported the issue to federal workplace safety regulators. The employee provided pictures and videos showing steam or smoke filling a room, water pouring from a wall near an electrical outlet, and oil-like substances leaking from equipment. | high |
| 05 | After the explosion damaged homes and forced evacuations, many properties were burglarized repeatedly because doors, windows, and entryways broke in the blast. Even after receiving repeated notice of burglaries, Givaudan did not provide or effectuate reasonable security measures. | high |
| 06 | Givaudan has not provided compensation for the big ticket items including damage to property caused by the explosion and reasonable long-term housing for displaced residents. The company paid lip service to offering some help while class members bore the brunt of financial impact themselves. | high |
| 07 | The factory was located in a mixed-zoned neighborhood sandwiched on all sides by private residences, small apartment buildings, single-family homes, and popular retail shops and restaurants. It was extremely foreseeable that even a small explosion would cause acute injuries to residents and businesses. | medium |
| 08 | Many individuals located within the evacuation area will never be able to return or have already been forced to permanently leave. The evacuation order continues to this day, weeks after the explosion. | high |
| 01 | After the 2003 explosion, the U.S. Chemical Safety and Hazard Investigation Board determined there were no effective programs in place to determine if equipment and processes met basic engineering requirements. The tank that failed had no relief device for overpressure protection. | high |
| 02 | The 2003 investigation found no basic process control or alarm instrumentation to prevent process upsets. There were no adequate operating procedures or adequate training programs to ensure operators knew how to respond appropriately to overheating risks. | high |
| 03 | Despite the 2003 findings, the same fundamental type of vessel failure occurred again in 2024. The vessel became overpressurized, did not vent properly, and exploded, indicating that lessons from the first disaster were not implemented or enforced. | high |
| 04 | An employee reported leaking sulfur dioxide to federal workplace safety regulators before the explosion, yet the facility continued operations without apparent intervention or enforcement action. | medium |
| 01 | Givaudan continued running Cooker No. 6 despite days of employee warnings about overheating. The company prioritized maintaining production over addressing the known safety hazard that employees considered dangerous enough to avoid walking near. | high |
| 02 | The factory manufactured caramel color additives for food and beverage products in a densely populated neighborhood. The importance of this use was minimal and had no value compared to the countervailing risks borne by nearby residents. | medium |
| 03 | Givaudan failed to mitigate damages and increased harm to plaintiffs and class members by failing to provide adequate security measures, resulting in further property damage from repeated burglaries of evacuated homes. | high |
| 04 | The company has not compensated residents for property damage or provided long-term housing solutions, forcing displaced families to scramble for adequate housing in a tough rental market during the holiday season. | high |
| 05 | Givaudan had actual or constructive notice of the hazard that led to the explosion prior to the event and failed to address it. It was reasonably foreseeable that the explosion would occur given the company’s history and failure to adequately monitor equipment. | high |
| 01 | The explosion resulted in millions in property damage suffered by both businesses and private individuals living within the vicinity of the factory. Residents have been left scrambling to find adequate housing while still liable for mortgages or leases on places they cannot occupy. | high |
| 02 | Multiple blocks surrounding the facility were placed under evacuation orders that continue to this day. Many residents will never be able to return or have already been forced to permanently leave. | high |
| 03 | Properties within the evacuation zone were burglarized repeatedly after the explosion. A police report from November 23, 2024 noted that entry to one victim’s garage was gained through a hole caused by the explosion itself. | high |
| 04 | Residents and businesses have been forced to bear the brunt of the financial impact themselves. Givaudan has not provided compensation for big ticket items like property damage and reasonable long-term housing. | high |
| 05 | The explosion caused a shelter-in-place order for a one-mile radius from the area, affecting hundreds if not thousands of owner-occupants and renters of residential property. | medium |
| 06 | Class members have had to shoulder costs for temporary housing, property repairs, replacement of stolen belongings, and lost wages, all while Givaudan offered only minimal assistance. | medium |
| 01 | One employee warned coworkers about Cooker No. 6 days before the blast, saying it had been overheating for several days. According to workers, the employee explicitly told them not to walk past the equipment. | high |
| 02 | An employee raised concerns with management about leaking sulfur dioxide prior to the incident and reported the issue to federal workplace safety regulators. The employee provided pictures and videos as evidence showing dangerous conditions inside the plant. | high |
| 03 | The employee’s evidence showed steam or smoke filling a room, water pouring from a wall near an electrical outlet, and an oil-like substance leaking from equipment. Despite this documentation, Givaudan allegedly maintained a practice of not fixing known safety issues. | high |
| 04 | At least two workers died in the November 2024 explosion, and dozens more suffered personal injuries. The 2003 explosion at the same facility also killed an employee. | high |
| 01 | The explosion sent off literal shockwaves throughout Louisville, much like a large bomb, killing at least two people and injuring dozens more. The blast caused massive damage to properties within one to two miles. | high |
| 02 | Authorities issued an immediate shelter-in-place order for a one-mile radius and an evacuation order for multiple blocks that continues to this day, weeks after the explosion. | high |
| 03 | The explosion caused energy, sound, and shock waves that physically damaged personal property, forcing some class members out of their homes entirely and forcing others to be involuntarily confined in their residences. | high |
| 04 | A police report noted that the explosion caused a hole in the side of a garage at plaintiffs’ property. The blast also caused massive amounts of debris and shrapnel to be strewn across lawns and throughout neighborhoods surrounding the factory. | medium |
| 05 | The back door to plaintiffs’ residence was left hanging off the frame after the explosion, effectively allowing burglars direct access to the house and contributing to repeated break-ins. | medium |
| 01 | Following the very public evacuation order and robust media coverage, it was public knowledge that residences within multiple blocks were vacant and that former residents had no reasonable way to remove their possessions and valuables. | medium |
| 02 | Because of damage caused by the explosion, residences suffered severe damage such that many doors, windows, and entryways broke, allowing easy access inside. Predictably, many properties within the evacuation zone were burglarized repeatedly. | high |
| 03 | Residents both within and outside the evacuation zone have been left scrambling to find adequate housing in the midst of a tough rental and property market in the middle of the holiday season. | medium |
| 04 | Many individuals located within the evacuation area will never be able to return or have already been forced to permanently leave their homes and neighborhoods. | high |
| 05 | The factory was located in a mixed-zoned neighborhood surrounded on all sides by private residences consisting of small apartment buildings and single-family homes, as well as some of Louisville’s most popular retail shops and restaurants on Frankfort Avenue. | medium |
| 06 | Plaintiffs along with many other class members provided notice to Givaudan of the burglaries but did not receive reasonable security to ensure that further burglaries would be prevented. Criminals came back again and again. | high |
| 01 | This is not the first time this specific facility exploded from a vessel failure. In 2003, an employee died after a catastrophic vessel failure that appears to have failed due to becoming overpressurized, just like the 2024 explosion. | high |
| 02 | Givaudan had actual or at least constructive notice of the hazard that led to the explosion prior to the event and failed to address it. At a minimum, it was reasonably foreseeable that the explosion would occur given the company’s history. | high |
| 03 | Givaudan intentionally, recklessly, willfully, maliciously, grossly, and negligently failed to properly maintain, occupy, or operate the factory, causing injuries to plaintiffs and class members according to the complaint. | high |
| 04 | The company failed to adequately monitor and oversee its equipment and failed to properly train or oversee its employees despite knowing the risks from the 2003 disaster. | high |
| 05 | Givaudan’s use of the factory did not contribute to the growth or prosperity of the community. The countervailing risks borne by the factory’s operation were not outweighed by any benefit. | medium |
| 01 | Givaudan knew the risks. Employees warned management for days about Cooker No. 6 overheating. An employee had reported leaking sulfur dioxide to federal regulators. The same facility had a fatal explosion in 2003 from the same type of failure. | high |
| 02 | The company chose production over safety. Despite all the warnings and the history, Givaudan kept the dangerous cooker running until it exploded, killing at least two people and devastating an entire neighborhood. | high |
| 03 | Residents are paying the price. Hundreds of people were forced from their homes, many permanently. Their properties were burglarized repeatedly while Givaudan failed to provide security. The company has not compensated them for property damage or long-term housing. | high |
| 04 | This pattern repeats when corporations prioritize profit over people. Without meaningful accountability and enforcement, companies like Givaudan can externalize the costs of their negligence onto workers and communities. | high |
