GREENVILLE, Miss. — An explosion at a chemical manufacturing plant in Mississippi on Wednesday, Nov. 4, sent thick black smoke into the sky and prompted emergency officials to order nearby residents to shelter indoors amid concerns about potentially hazardous chemical exposure.

The explosion occurred shortly after 7 a.m. at the Loveland Products facility, formerly known as Platte Chemical, in Greenville, a Mississippi Delta city approximately 120 miles northwest of Jackson. Firefighters and hazardous materials teams responded as smoke spread from the industrial site.

Authorities issued a shelter-in-place order shortly before 9:30 a.m. for surrounding neighborhoods. The restrictions were lifted later Wednesday morning after firefighters brought the fire under control, according to updated reporting from Action News 5.

No injuries were reported, although emergency responders underwent precautionary decontamination procedures because of possible chemical exposure.

Preliminary information provided by plant management indicated that the explosion involved a fire associated with an herbicide chemical inside equipment described as a “hot box.” The exact cause of the explosion and the chemical substances involved had not been publicly established.

According to The Associated Press, emergency crews were notified shortly after 7 a.m. Sara Moreland Hester, Washington County’s deputy emergency management director and a local firefighter, said the fire was controlled by midmorning but had not yet been completely extinguished.

The Greenville Fire Department requested assistance from neighboring agencies as emergency personnel worked to contain the fire and determine whether additional protective measures were necessary.

Firefighters from Riverside, Leland and Greenville Mid-Delta Airport responded, with airport personnel supplying specialized firefighting foam. Pafford Emergency Medical Services was placed on standby, while regional hazardous materials teams assisted with containment and safety operations.

The Mississippi Department of Environmental Quality and federal Environmental Protection Agency also dispatched personnel to assess potential environmental contamination and monitor air quality.

Greenville Mayor Errick D. Simmons emphasized protecting residents, emergency personnel and employees at the facility.

“Our first priority is the safety of our residents, our first responders, and everyone working at or near the facility,” Simmons said, according to local television station WTVA.

“We are coordinating with emergency response agencies to assess the situation, contain the fire, and determine whether additional protective measures are necessary,” he added.

The Washington County Emergency Operations Center initially directed residents in areas surrounding Highway 182 and VFW Road, between Beauchamp Road and Kuehn Road, to remain inside their homes and businesses.

Officials instructed residents to close windows and exterior doors, shut down ventilation systems drawing outdoor air into buildings and avoid outdoor activity until authorities determined the smoke no longer posed an immediate threat.

According to Fox Weather, emergency officials warned that exposure to smoke from the chemical fire could cause burning or watering eyes, persistent coughing, throat irritation, headaches, dizziness, nausea and breathing difficulties.

Residents experiencing serious symptoms, including chest pain, difficulty breathing, confusion, fainting or seizures, were advised to seek emergency medical assistance.

Although the shelter-in-place order was subsequently canceled, authorities continued urging the public to avoid the immediate area of the facility while firefighters completed their operations and environmental personnel evaluated possible contamination.

Anyone who believed they had been exposed to hazardous fumes was encouraged to obtain medical evaluation.

Loveland Products is a subsidiary of Nutrien, a major agricultural products company. Loveland manufactures and distributes products used in agriculture, including herbicides, fertilizers, plant nutrition products and other crop protection chemicals.

The company is headquartered in Loveland, Colorado, and operates facilities serving agricultural producers across the United States.

Nutrien acknowledged the Greenville incident and said company officials were coordinating with emergency personnel.

The company described the fire as “being managed” and confirmed that facility leadership was working with first responders, according to the Associated Press.

The explosion raised concerns about potential environmental hazards because industrial agricultural chemicals can produce dangerous fumes or combustion byproducts when exposed to intense heat.

The specific health and environmental risks depend on the substances involved, the quantity released, weather conditions and the duration of exposure. Officials had not released sufficient information to determine whether hazardous chemical concentrations had spread beyond the facility.

The involvement of state and federal environmental agencies will help establish whether the explosion caused contamination requiring further cleanup or monitoring.

The Washington County Emergency Operations Center confirmed that firefighters and other emergency personnel were undergoing decontamination as a precaution after working near the affected equipment.

The procedure does not necessarily indicate that responders suffered chemical injuries, but is commonly used following operations involving potentially hazardous substances.

The explosion occurred in Greenville, a city of approximately 26,000 residents in Washington County, where agricultural production and related industries contribute to the regional economy.

Local authorities said the incident remained under investigation and that additional information about the cause, chemicals involved and any environmental consequences would be released as it became available.

With the fire contained and the shelter-in-place order lifted, emergency crews continued securing the facility while environmental officials assessed air quality and potential chemical exposure.
