A massive six-alarm fire destroyed a 1.2 million-square-foot Kimberly-Clark distribution center in Ontario, California, leading to the arrest of a male employee on multiple felony arson charges. The blaze, which erupted early Tuesday morning, gutted the facility and caused extensive damage to the surrounding area, though authorities confirmed that no injuries were reported among the staff onsite.
The incident began around 12:30 a.m. When the Ontario Fire Department responded to reports of smoke and flames at the warehouse located in the 9500 block of Merrill Avenue, near Eucalyptus and South Hellman Avenue. First-arriving units described heavy fire conditions and smoke billowing from the roof, necessitating a defensive fire attack and an immediate request for additional resources according to CBS News.
The scale of the disaster required a coordinated effort from more than 140 firefighters across multiple agencies, including departments from Los Angeles, San Bernardino, and Riverside counties. Despite the activation of the internal sprinkler system, the sheer volume of combustible materials—primarily household paper products such as toilet paper and Kleenex—fueled the intensity of the fire, leading to a partial roof collapse and the total loss of the building and its inventory as reported by Fox LA.
Employee Detained as Primary Arson Suspect
Following the eruption of the fire, authorities identified a male employee as the primary suspect. According to official reports, the individual had been reported missing during the initial evacuation of the building. Ontario Police Department detectives subsequently detained the suspect, who is an employee of a third-party distributor that operated the facility per CBS News.

Cal Fire officials noted that the presence of fire throughout the warehouse, despite active sprinklers, indicated that the blaze was likely not an accident. The suspect now faces multiple felony arson charges in connection with the destruction of the 1.2 million-square-foot facility according to law enforcement sources.
Impact on Local Community and Operations
The environmental impact of the fire was immediate, and significant. Aerial footage captured clouds of black smoke covering the nearby area, and ash was reported to have fluttered into the yards of homes located across the street from the warehouse. Due to the poor air quality resulting from the burning paper goods, fire officials urged seniors and children in the vicinity to remain indoors according to CBS News.
In addition to the loss of the distribution center and its inventory, several big-rig trucks stationed at the loading docks were either damaged or completely destroyed by the flames. A spokesperson for Kimberly-Clark confirmed the company was aware of the fire and emphasized that safety was their top priority, noting that they were working closely with their third-party partner and local authorities to manage the aftermath per a company statement.
