Evacuation orders issued in California city over chemical tank: ‘It fails or it blows up’

An emergency hazmat incident at an aerospace facility in Garden Grove, California, has caused evacuations in the area. The situation arose when a chemical tank containing methyl methacrylate at an aerospace manufacturing company began leaking vapor from its 34,000-gallon capacity. The Orange County Fire Authority responded to the scene and discovered that the tank was in a critical state, with the potential for either a catastrophic failure or an explosion.

City officials confirmed that while there is currently no active gas leak or plume, the tank remains unstable and cannot be secured due to damage to a valve. Orange County Fire Authority Division Chief Craig Covey expressed the urgency of the situation, explaining that the tank could release thousands of gallons of hazardous chemicals into the surrounding area or potentially detonate, posing a significant risk to nearby tanks containing fuel or other chemicals.

As a precautionary measure, authorities have issued evacuation orders affecting approximately 40,000 residents in the vicinity. Several schools have been closed temporarily, and outdoor activities have been canceled as a safety measure. The Garden Grove Unified School District emphasized the need for caution and compliance with evacuation directives.

During a press briefing, Covey disclosed that the facility houses three tanks, with only one currently in crisis. The tank in question experienced a spike in temperature and exhibited signs of bulging, indicating internal pressure buildup. Efforts to neutralize the chemical within the tank have been unsuccessful, and broken valves have hindered the transfer of the substance.

Although initial evacuation orders were lifted when vapor conditions improved, subsequent developments prompted a reinstatement and expansion of the evacuation zone. The unprecedented nature of the event has left officials uncertain about the timeline for residents to return home.

Methyl methacrylate, the chemical in the compromised tank, is commonly used in industrial processes such as plastics manufacturing. It is known to cause respiratory irritation and poses significant health and safety risks. Authorities estimate that approximately 7,000 gallons of the chemical remain in the tank.

The aerospace manufacturing company involved, GKN Aerospace, has yet to provide a statement on the incident. California Governor Gavin Newsom has been briefed on the situation, and the Governor’s Office of Emergency Services is actively monitoring and providing support to local response efforts.

Residents are urged to adhere to evacuation orders and follow instructions from local authorities to ensure their safety. The gravity of the situation underscores the need for swift and coordinated action to mitigate the potential danger posed by the unstable chemical tank. Garden Grove, located about 30 miles southeast of Los Angeles, is at the center of this unfolding crisis.
