More than 30 lawsuits have been filed against GKN Aerospace after one of the company’s tanks containing a highly flammable chemical overheated and threatened a catastrophic explosion last month, forcing the evacuation of about 50,000 residents in California’s Orange County.Debbie Cohran, who lives about 500 feet (152 meters) from the aerospace facility in Garden Grove, wasn’t told to evacuate until several hours after the leak started, according to her complaint. Her suit said she experienced nausea and headaches for several days afterward.Melanie Rose Burciaga of nearby Westminster had just given birth to her first child and had to leave the hospital when the evacuation orders came in, her lawyer said in a lawsuit.And Juan Diego Orozco was part of a street repair crew working in Garden Grove on the day the overheating started. He said he suffered a headache and went to the hospital due to difficulty breathing and vomiting, his lawyer said.

More than 100 individuals — including some families with pets — as well as local businesses are suing GKN Aerospace, saying the U.K.-based company was negligent in maintaining a safe facility, especially since it’s located in a large population center.
