Around 40,000 people were ordered to evacuate their homes in the Los Angeles suburb of Garden Grove due to a failing chemical tank that was likely to either leak or explode, possibly releasing toxic vapor into the air, first responders said.⁣ ⁣ The malfunctioning tank contained methyl methacrylate, a flammable, volatile chemical used in plastics and manufacturing at an aerospace plant.⁣ Authorities reported that about 15% of people ordered to leave refused to do so. Health officials were concerned that vapor could escape with the potential of causing severe respiratory issues in the event of prolonged exposure. ⁣ ⁣ Firefighters doused the tanks with water using a mechanical device that kept humans at a safe distance, stabilizing the temperature and "buying us time," reported Craig Covey, division chief of the Orange County Fire Authority.⁣ So far air quality monitors had not detected any vapor, according to the Orange County Health Care Agency.⁣ ⁣ #usa #california #chemical #evacuation...
