9/9/2026, 12:24:15 PM
Incident Overview
On September 8, 2026, a slow leak from a chemical tank at a one-story commercial building on the 500 block of South Cypress Street in La Habra, California, produced an orange plume that rose from the roof. Los Angeles County fire crews arrived shortly before noon, mitigated the leak, and confirmed that the plume had dissipated by mid-afternoon. A shelter-in-place advisory covering a one-mile radius was lifted at approximately 2:30 p.m., and the affected streets were reopened.
Background & Context
The facility manufactures household cleaning products. It is the second chemical incident in the region this year, following a near-explosion at a tank in Garden Grove that forced the evacuation of more than 50,000 Orange County residents. The incidents have prompted officials and legislators to question oversight of industrial chemical operations in mixed-use neighborhoods.
Data & Statistics
- Geographic scope: One-mile radius around the 500 block of South Cypress Street.
- Personnel on scene: Three employees were examined by paramedics; all declined transport.
- Visibility: An orange plume was visible for several hours, prompting social-media posts and photographs.
- Injuries: Official statements report no injuries among the workers.
Official Statements & Responses
Los Angeles County Fire Department spokesperson Kaitlyn Aldana said the specific chemical and the precise origin of the leak remain unknown. Fire Capt. Eddie Diaz reported that the three employees showed no signs of injury or discomfort.
Mayor Jose Medrano urged residents to shelter in place and ordered the evacuation of streets east of Euclid Street to Harbor Boulevard and Cypress Street between La Habra Boulevard and Lambert Road. The La Habra Police Department posted road-closure notices and coordinated the temporary evacuation of Washington Middle School, located about half a mile from the site.
On-the-Ground Reports
Local resident Luis Gomez, who manages a nearby pickleball program, observed the orange cloud and called police, later recounting that authorities instructed anyone within the one-mile radius to leave the area immediately. Several residents posted videos of the plume on social media, describing it as an “orange haze” that lingered above the neighborhood.
Conflicting Reports & Gaps
- Chemical identity: Initial statements described the substance as unknown, while later remarks from Capt. Katon characterized it as inert.
- Injury reports: The fire department indicated no injuries, whereas a separate outlet reported at least one minor injury among those evaluated.
- Terminology: Early communications used “mandatory evacuation,” but the advisory was later downgraded to “shelter-in-place” before being lifted.
