Authorities in Southern California have released a detailed map outlining the areas at risk if a leaking chemical storage tank at the Garden Grove aerospace facility were to explode.
The Orange County Fire Authority has been closely monitoring the situation at GKN Aerospace, where a 34,000-gallon tank containing methyl methacrylate-a highly flammable liquid-overheated on Thursday, releasing hazardous vapors into the air.
As a precaution, approximately 40,000 residents have been ordered to evacuate amid concerns the tank could either rupture or explode, potentially releasing thousands of gallons of dangerous chemicals. Fire officials have now provided a clearer picture of the possible blast radius and affected neighborhoods.
In a Saturday update, Orange County Fire Authority Division Chief Craig Covey reported that the tank’s internal temperature was steadily rising at about one degree per hour, reaching 90 degrees. Meanwhile, Governor Gavin Newsom declared a state of emergency for Orange County, mobilizing additional shelters and emergency response resources for displaced residents.
Later that day, Division Chief Nick Freeman shared a map illustrating the potential impact zones if the tank were to fail catastrophically. The map features three concentric blast zones and three distinct impact zones:
- The innermost blast zone would face severe structural damage and significant harm.
- The middle zone could experience structural damage and pose danger to people within its boundaries.
- The outermost blast zone might see limited structural damage.
Regarding the impact zones, Freeman explained:
- The red zone marks areas at risk of fire or flash fire due to flammable vapors.
- The orange zone indicates regions immediately dangerous to life and health from chemical exposure.
- The yellow zone represents a non-hazardous area where the chemical’s odor can be detected but poses no direct threat.
Orange County Health Officer Regina Chinsio-Kwong emphasized the careful consideration behind the evacuation order, stating, “This diagram shows you the evacuation zone that was carefully selected, taking into consideration the worst-case scenario. If you are not in the evacuation zone in red here, you do not need to worry.
Just stay informed with any updates that you see. Now, if you remain in the evacuation zone, that’s where your risk increases.”
Authorities continue to monitor the situation closely and urge residents to follow evacuation orders and stay updated on developments.
