India, May 26 -- Nearly 50,000 residents across parts of California remain under evacuation orders after a dangerous chemical emergency at a GKN Aerospace facility in Garden Grove triggered fears of a possible explosion and toxic leak.

Emergency crews in Southern California have been working through the night to stabilise a massive storage tank containing around 7,000 gallons of methyl methacrylate, a highly flammable chemical used in plastics and resin manufacturing.

Authorities said the chemical inside the tank overheated on Thursday, raising concerns that pressure could build up and cause a catastrophic explosion.
