On Tuesday evening, California officials lifted the remaining mandatory evacuation orders for some 16,000 residents in Garden Grove, California, who live near an overheated chemical tank at a GKN Aerospace facility. Evacuation orders for some 50,000 residents were initially issued last Thursday, rescinded later that same evening, and then reissued Friday morning.
A 34,000-gallon storage tank at the facility containing methyl methacrylate (MMA), a volatile and flammable chemical, was found to be leaking. The chemical is not only dangerous when inhaled, but also posed the risk of causing a massive toxic explosion.
While the evacuation orders were lifted Tuesday night, police and emergency personnel are maintaining a several-block closure around the facility as chemicals continue to leak from the ruptured tank.
In addition to thousands of residences, several schools are also located close to the facility.
