Evacuations in Garden Grove Due to Chemical Tank Emergency
Emergency Situation in Garden Grove
On Friday, numerous residents in certain areas of Garden Grove were still under evacuation orders as officials expressed concerns over a large chemical storage tank at an aerospace facility that might rupture or explode. Emergency responders from the Orange County Fire Authority and local police were dispatched to the GKN Aerospace site on Western Avenue around 3:30 PM local time on Thursday. Authorities reported that a chemical within a 34,000-gallon tank had overheated, leading to the release of vapors and triggering an internal sprinkler system meant to cool the contents. The chemical in question is methyl methacrylate, a hazardous and highly flammable material utilized in acrylic plastics manufacturing.
Firefighters worked throughout the night, applying water to the tank to lower temperatures and stabilize the situation. Although evacuation orders issued on Thursday were temporarily lifted later that evening due to perceived improvements, they were reinstated on Friday morning due to deteriorating conditions, as stated by fire officials. The evacuation zone was expanded to establish a safety perimeter of approximately one mile around the facility.
During an online briefing on Friday, OCFA Division Chief Craig Covey indicated that emergency teams had determined that the most critical tank could no longer be adequately secured. He stated, “The tank that is in the biggest crisis is in fact unable to be secured and mitigated.” Covey outlined two potential outcomes: either the tank fails, releasing about 6,000 to 7,000 gallons of hazardous chemicals into the surrounding area, or it enters a thermal runaway, resulting in an explosion that could impact nearby tanks containing fuel or chemicals.
Despite the risks, Covey reassured that there was “no active gas leak, no plume in the area,” but he urged residents to adhere to evacuation orders due to the ongoing threat of a spill or explosion. Air quality monitoring in the vicinity has indicated safe levels thus far. The evacuation zone encompasses areas north of Trask Avenue, south of Ball Road, east of Valley View Street, and west of Dale Street. Evacuation centers have been established at the Garden Grove Sports & Recreation Center and another location on Orange Avenue in Cypress. Garden Grove Police Chief Amir El-Farra noted that around 40,000 residents were impacted by the evacuation order, although approximately 15% were reluctant to leave. Officials have consistently urged residents to follow evacuation directives, emphasizing that the situation remains extremely hazardous.
