A chemical leak in La Habra, California, has prompted mandatory evacuations and shelter-in-place orders as a plume of yellow smoke containing potentially toxic fumes spread Tuesday.
First responders and specialized hazmat crews were called to the scene near 334 S Cypress St following reports of a dangerous reaction involving nitric and phosphoric acid. Emergency personnel are executing a mandatory evacuation for all residents and businesses within a one-mile radius of the incident. Officials are warning that anyone downwind should shelter indoors, close windows, and shut off HVAC systems if evacuation is not immediately possible.
Mayor of La Habra, José Medrano, stated on social media that the Los Angeles Housing Department and Los Angeles County Fire Department are investigating the leak, believed to be originating from a compromised storage tank at 503 South Cypress Street. Areas east of Euclid Street to Harbor Boulevard and Cypress Street between La Habra Boulevard and Lambert Road have been blocked off, with evacuations underway. Residents are urged to stay out of the affected area.
At least one person has sustained minor injuries, and paramedics are evaluating three other patients experiencing varying levels of physical distress. Fire crews are working to locate the source of the leak and contain the chemical reaction to prevent further spread into surrounding neighborhoods.
