Officials said the affected tank contains methyl methacrylate, a highly flammable and toxic industrial chemical. The substance is used in the production of acrylic plastics. Fire officials said overheating caused the tank to release vapors and destabilize the storage system.
Emergency teams warned that a failure could release thousands of gallons of toxic material into the surrounding area. They also said an explosion could impact nearby storage tanks containing additional hazardous chemicals. Authorities have deployed containment barriers to reduce environmental contamination risks.
