In Southern California, tens of thousands of residents have faced evacuation after warnings that a chemical tank at an aerospace facility could potentially explode. The tank, located at GKN Aerospace, holds about 7,000 gallons of methyl methacrylate, a flammable substance used in plastics production.
State of Emergency
Governor Gavin Newsom declared a state of emergency for Orange County, mobilizing state resources to assist local responders. The goal is to ensure community safety in light of the potential hazard posed by the chemical tank.
Methyl methacrylate generates heat independently, which can lead to fire or explosion if it leaks. Fire officials are actively working to keep the tank cool.
Increasing Temperatures
Initially, authorities believed the tank’s temperatures were dropping. However, upon further inspection, temperatures were found to be rising by approximately 1 degree per hour. Chief Craig Covey of the Orange County Fire Authority noted temperatures reached 90 degrees Friday night.
Covey described this event as the most dangerous he has encountered in his decades of fire service. No injuries or fatalities have been reported to date.
Health Risks
Methyl methacrylate is known to irritate the respiratory system and can cause irritation to the lungs, skin, and eyes. Exposure could also result in nausea and dizziness.
Potential Scenarios
Covey highlighted two possible outcomes. The tank could fail, spilling chemicals and forming vapor that would settle and sink due to its weight. Sandbags have been employed to prevent the chemical from entering waterways.
Alternatively, the tank could explode, dispersing particles into the air and affecting nearby tanks containing chemicals and fuel.
Efforts to maintain tank coolness are ongoing. Covey emphasized finding a safe resolution to this incident, stating that letting the situation escalate uncontrollably is not an option.
Fortunately, no harmful particles have entered the air thus far. Residents have been encouraged to remain indoors.
Evacuation orders cover homes within one mile of the facility. There is currently no set timeline for lifting these orders, and the cause of the leak is under investigation.
