MORGANTON, N.C. — For many residents of Burke County, Jan. 31, 2006, remains a date etched in memory, marked by an explosion that rocked the Synthron chemical plant and changed countless lives. While the incident may not be as broadly remembered as events like the assassination of President John F. Kennedy or the September 11 attacks, its impact continues to reverberate in the community. A total of twelve employees were injured, and the maintenance supervisor, Butch Brackett, tragically lost his life.
On the 20th anniversary of the explosion, local industrial safety engineer Bryan Raughley has been examining the incident as a case study to improve safety measures in similar plants. Raughley emphasizes the importance of understanding the sequence of events that led to the disaster to prevent future tragedies.
Founded in 1963, Synthron was a producer of chemical additives, utilizing a labor-intensive process reliant on manual handling of hazardous materials. Employees followed painstaking recipes for chemical mixtures, which were kept in large storage containers visible from the road. Despite the company’s operational complexity, the absence of modern automation systems raised concerns regarding safety protocols, as workers relied on manual processes for transferring chemicals and monitoring equipment.
In the years leading up to the explosion, significant staffing changes occurred, including a new management team that lacked extensive experience in the specific chemistry at play. This management restructuring coincided with former employees reporting that production demands were pushing safety protocols aside. Investigators found that a plant superintendent had previously raised concerns about the risks associated with increasing production without adequate equipment.
Just two months before the explosion, Synthron received a large customer order that required a significant increase in their standard production batch. Instead of opting for safety reviews or consulting corporate headquarters, the decision was made to scale up the recipe on the production floor. This deviation from standard operational procedures, which typically would invoke a formal safety assessment, was critical in initiating a succession of events that would lead to the explosion.
On the day of the incident, workers encountered complications when they discovered a low inventory of one solvent. Instead of halting production to procure more materials, they improvised, altering the chemical proportions. This choice, along with a high-risk decision to combine multiple stages of the blending process, proved catastrophic. When flammable solvents were heated and a chemical initiator was added, the situation quickly escalated beyond control, resulting in a runaway reaction.
As pressure and heat surged within the reactor, vapor escaped through an inadequately sealed tank opening. In moments, the flammable vapors ignited, enveloping the surrounding area in a dramatic explosion that injured many of the twelve employees present and ultimately led to Brackett’s death five days later.
Emergency services rushed to the scene to provide aid amid the chaos, confronting a massive industrial incident with both injuries and hazardous materials in play. The immediate community was ordered to stay indoors as responders worked to manage the scene, which was left in complete ruin.
The explosion serves as a somber reminder of the potential dangers inherent in chemical manufacturing. Raughley advocates for enhanced safety protocols and training for employees, emphasizing the need for thorough risk assessments in industrial settings. On this 20th anniversary, Raughley’s work aims to ensure that the lessons learned from Synthron’s tragedy lead to meaningful change in safety practices and employee training, fostering a safer environment for future generations.
