California Governor Declares Emergency as Orange County Chemical Leak Threatens Explosion
California Governor Gavin Newsom has declared a state of emergency in Orange County as emergency crews race to contain a volatile chemical leak at a manufacturing facility. Officials warned that a tank containing approximately 7,000 gallons of methyl methacrylate, a highly flammable substance used in plastic production, was at risk of structural failure.
Thousands of residents in Garden Grove have been evacuated as a precautionary measure. On Sunday, officials reported the discovery of a “potential crack” in the compromised tank, a development offering a glimmer of hope amidst severe warnings. Previously, Orange County Fire Authority division chief Craig Covey outlined two dire scenarios: a rupture and spill, or a catastrophic explosion.
A specialised team was dispatched on Saturday night to investigate the aerospace facility, located roughly 8km from Disneyland. Interim Fire Chief TJ McGovern confirmed that firefighters had “visualised the tank” and located a “potential crack… which could potentially be relieving some of the pressure.” Experts are currently analysing data to determine the next course of action.
The incident is under investigation, with emergency teams continuously spraying the tank with water to stabilise its temperature. An “inoperable valve” has presented “additional operational challenges,” exacerbating the situation. On Saturday, the tank’s internal temperature had risen to 32°C, increasing by approximately one degree Fahrenheit per hour, despite earlier efforts to cool it externally to 16°C using drones.
Covey expressed hope that emergency teams could decelerate the chemical reactions driving the temperature and pressure increase within the tank. He emphasised that “letting this thing just fail and blow up is unacceptable.” Aggressive contingency plans include the construction of dykes and dams to contain any potential chemical spills, preventing contamination of storm drains or the ocean.
Local schools have been closed, and several major road exits are shut to restrict access to the affected area. Dr Regina Chinsio-Kwong, Orange County health officer, advised residents to report any “fruity and heavy smell” to authorities, cautioning that inhaling the vapour could cause respiratory issues, eye irritation, and dizziness. She reassured those outside the one-mile evacuation zone of their safety.
The facility is operated by GKN Aerospace, a UK-based company manufacturing aircraft parts. A company spokesperson issued an apology to local residents, stating, “The situation remains ongoing and we are fully focused on working with emergency services, specialised hazardous material teams and the relevant authorities to ensure the safety of the local community, our employees and everyone else involved.”
