GREENVILLE, Miss. — An explosion at a chemical manufacturing facility in Greenville Wednesday morning sent thick black smoke into the sky, prompting a major emergency response and temporary shelter-in-place instructions for nearby residents.
The incident occurred shortly after 7 a.m. November 4 at the Loveland Products facility, formerly known as Platte Chemical, according to reporting based on information from Washington County emergency officials.
Firefighters and hazardous-materials personnel responded as authorities worked to contain the blaze and assess possible chemical exposure.
By Wednesday afternoon, officials reported that the fire was under control and the shelter-in-place order had been lifted. No injuries had been reported at the time of the latest available update. wlox.com+1
The initial explosion reportedly involved a chemical herbicide stored inside a heated storage unit described by city officials as a “hot box.”
The blast triggered a fire that produced a large column of dark smoke visible around the Greenville area.
As emergency crews responded, authorities issued shelter-in-place instructions shortly before 9:30 a.m. for residents in an area bounded by Highway 182, Beauchamp, Kuehn Road and VFW Road.
The temporary restrictions were intended to protect residents while emergency personnel evaluated conditions around the facility.
Officials subsequently canceled the shelter-in-place order after the fire was contained.
The emergency brought together firefighters and public safety personnel from several communities.
Departments involved included Greenville, Riverside, Leland and Greenville Airport fire services.
Regional hazardous-materials teams also assisted, while representatives from the Environmental Protection Agency and Mississippi Department of Environmental Quality were dispatched to support monitoring and safety operations.
Emergency personnel working at the scene underwent precautionary decontamination procedures because of possible chemical exposure.
Authorities continued asking the public to avoid the immediate facility area while crews completed their work.
Although no injuries had been reported, the nature of the facility and the smoke raised concerns about potential exposure to hazardous substances.
Emergency officials advised anyone who believed they had been exposed to fumes to seek medical evaluation.
Symptoms that may warrant medical attention include persistent coughing, eye irritation, dizziness, nausea, chest tightness or difficulty breathing.
The lifting of the shelter-in-place order did not establish that every part of the facility was safe to enter or that environmental testing had been completed.
Residents were urged to continue following official public safety instructions.
Greenville Mayor Errick Simmons acknowledged the response by local and state emergency agencies and emphasized protecting residents, employees and first responders.
In a statement reported by local television news, Simmons said public safety remained the city’s priority as officials assessed the situation and determined whether additional protective measures were necessary.
The mayor also urged residents to avoid the affected area so emergency personnel could carry out their responsibilities.
The exact cause of the explosion remained under investigation as of Wednesday afternoon.
Officials had not publicly established the full extent of property damage or released final environmental monitoring results in the reports reviewed.
The incident highlights the importance of coordinated emergency planning in Mississippi Delta communities where agricultural industries, chemical storage and residential neighborhoods can operate near one another.
For Greenville residents, the immediate development was the containment of the fire and the lifting of the temporary shelter-in-place order.
Further information about the explosion’s cause, environmental findings and facility damage will depend on updates from emergency management officials and investigating agencies.
