Evacuation orders were reissued Friday for thousands of residents and schools were closed in Garden Grove due to continued concerns about a toxic chemical leaking from a large storage tank at an aerospace facility. An estimated 40,000 residents have been asked to evacuate, affecting portions of the cities of Garden Grove, Anaheim, Buena Park, Cypress, Stanton and Westminster. The incident took place at GKN Aerospace, which builds engine structures, landing gear and other products for commercial and military aircraft.

The chemical leak that triggered evacuations in Orange County is located at GKN Aerospace, a leading aerospace firm based in the UK. The company manufactures landing gear, jet engines and other materials for commercial and military aircraft. It has been at the Garden Grove, California, site since 2004. There are three large tanks with a highly toxic chemical called methyl methacrylate, or MMA, used to make plastic at the site in the 12000 block of Western Avenue in Garden Grove. It started experiencing a rise in temperatures on Thursday, which triggered temporary evacuations.

Long after the fighting is over, the toxic leftovers of war continue to poison communities and the environment. Pollution caused by war can settle over cities, contaminate water and soil, and shape public health long after the war is over. During the 1991 Gulf War, retreating Iraqi forces set fire to more than 600 Kuwaiti oil wells, causing widespread air pollution, contamination of soil and groundwater, and a generation of health consequences. Ukraine's ongoing war has created a toxic legacy, with attacks on fuel depots, industrial sites, chemical warehouses and energy infrastructure contaminating air, rivers and farmland.

Tens of thousands of people have been evacuated in Garden Grove, California, because of a potential chemical leak. The tank contains 26,000 liters of methyl methacrylate, a volatile and flammable liquid used to make plastics. Emergency services are trying to cool the tank and prevent an explosion.

A tank filled with a toxic chemical in Orange County is at risk of exploding or leaking. Firefighters are working to lower the temperature of the tank to 50 degrees. The tank contains 7,000 gallons of a chemical used to make plastics called methyl methacrylate, or MMA, stored in liquid form. MMA is highly flammable and toxic.

40,000 people in Orange County, California have been ordered to evacuate due to a chemical leak. The problem arose at a facility owned by GKN Aerospace in the town of Garden Grove, where a storage tank holding methyl methacrylate began off-gassing and threatened to fail. The chemical is used to fabricate resins and plastics and is highly flammable.

It's been six months since a crude oil spill near Ethan Higbee's home in Santa Paula, California. The oil contaminated at least three-quarters of a mile of a remote tributary of Sisar Creek. It was caused by a tank overfilling and improper rainwater valve management by oil and gas company Carbon California. About 420 gallons of crude oil was accidentally spilled.

40,000 people in Garden Grove, California, are under an evacuation order due to a chemical leak at an aerospace facility. The tank containing methyl methacrylate, used in plastic manufacturing, is in "crisis" and cannot be secured. Crews are working through the night to lower the temperature of the damaged tank.
