A shelter-in-place order has been issued in the Spring Valley area due to a hazmat incident that caused a gas cloud, officials said.

The incident was reported at around 11 a.m. on 10600 Jamacha Boulevard. The San Diego County Sheriff’s Department said a company “accidentally mixed two chemicals incorrectly and a gas cloud formed.”

Although an evacuation order has not been officially issued, the sheriff’s department told NBC 7 they have evacuated some businesses and residents.

Video from SkyRanger 7 showed what appeared to be a group of workers outside Caliber Collision, an auto repair shop, although it was unclear if that’s where the hazardous materials incident occurred.

At least one person appeared to be receiving medical attention and an ambulance could be seen arriving at the scene. It was not immediately clear if anyone was transported for injuries.

The shelter-in-place order has been activated within the following boundaries:

  • Zone ID: SDC-2153
    • NORTH OF Via Lampara
    • SOUTH OF Jamacha Boulevard, Trace Road
    • EAST OF Jamacha Boulevard, 10th Street
    • WEST OF Wagon Wheel Court 

The following streets have been closed according to Genasys Protect:

  • Sweetwater Springs Blvd

Officials are asking those within the boundaries to go indoors and shut and lock their doors and windows.
