ONTARIO, CA — Firefighters in Southern California were compelled to retreat from a rapidly advancing fire at a 1.2 million-square-foot warehouse Wednesday due to extreme heat and structural hazards, authorities said.
The blaze erupted early Wednesday morning at the industrial warehouse in Ontario, with flames quickly spreading throughout the large facility and generating dense smoke visible for miles.
Crews from multiple agencies responded to the scene and initially attempted an interior attack, but advancing fire conditions and safety concerns prompted a shift to defensive operations outside the structure.
Evacuation orders were issued for nearby businesses and portions of the surrounding area as fire officials worked to contain the blaze and prevent spread to additional structures.
Officials with the local fire department and fire investigation units are conducting an ongoing probe into the cause and origin of the fire, and no confirmed cause has been released.
Firefighting efforts continued through Wednesday with coordinated hose lines, aerial water application, and mutual-aid support as temperatures and operational risks remained high.
