Medline Fire in Tracy Leaves 1 Million Square Foot Building ‘Total Loss’

TRACY, CA – A fire that started on the roof of Medline Industries’ distribution center in Tracy on the afternoon of June 11, 2026, destroyed the entire 1-million-square-foot facility within 30 to 40 minutes, wiping out the company’s primary Northern California medical supply hub and displacing approximately 1,000 workers.

South San Joaquin County Fire Authority Chief Randall Bradley said crews responded to reports of a roof fire at 5701 Promontory Pkwy shortly after 1 p.m. and found heavy flames already bearing down on the building. The fire extended laterally across the high-rack storage stacks so rapidly that firefighters could not contain it before the entire structure was engulfed. Bradley called it one of the largest warehouse fires in California history, comparable to only three or four similar events nationwide.

All 120 employees inside evacuated safely, and no injuries were reported among workers or firefighters.

Medline Sprinklers Did Not Activate, Response Delayed

What transformed a roof fire into a total loss is a question that fire investigators, Cal/OSHA, and the families of the roughly 1,000 displaced workers are all asking.

Deputy Chief Brian Bagley of the South San Joaquin County Fire Authority said the sprinkler system at the Medline warehouse had been inspected by a third-party contractor and fully signed off in January 2026 — just six months before the fire. When crews entered the building, the sprinklers did not activate. The fire marshal on scene checked the fire pump room and found zero water pressure. That same pump system feeds the on-site hydrants, which also lacked adequate pressure when firefighters attempted to use them.

“When our crews were engaging in the firefight, they did not recognize any fire sprinkler activations at all, throughout the entire facility,” Bagley said. “And they were in there for a solid 10 minutes trying to knock down the fire.”

Crews ultimately had to connect to city water mains outside the property, adding critical minutes to the response. During that delay, the fire spread through pallets of medical supplies stacked high on warehouse racks — exactly the type of high-piled storage that state fire code requires special suppression plans to address. The facility also held two AutoStore robotic picking systems containing a combined 174 lithium-ion battery-powered robots. When those batteries burned, they produced hydrogen fluoride gas, requiring firefighters to use specialized breathing equipment throughout the multi-day operation. Crews burned through roughly one million gallons of water in the first 10 hours alone, deploying 4,000 gallons per minute at peak.

Bagley described the scope in terms familiar to wildfire response: “It’s a skyscraper laying on its side.”

The fire spread across the street before crews contained a separate blaze at the adjacent FedEx hub. Spot fires from wind-driven embers ignited areas near Tracy Municipal Airport and along Schulte and Larch roads, all of which were contained. No residential evacuations were ordered, though the San Joaquin Valley Air Pollution Control District and San Joaquin County Office of Emergency Services urged residents near Tracy to shelter indoors, close windows, and keep pets inside. Sensitive groups — children, older adults, and people with cardiac or respiratory conditions — were advised to take additional precautions. Fire officials maintained multiple air quality monitoring stations throughout the incident.

Medline Employee Recounts Locked Gates, No Head Count

A week after the fire, a Medline receiving department employee named Jasmine “Jas” Caceres spoke publicly about the company’s evacuation response — and the account raised questions independent of the fire’s cause.

Caceres said they were nearing the end of their shift when a coworker began shouting about smoke before any alarm had sounded. The fire alarm began flashing shortly after.

About three dozen workers, by Caceres’ estimate, made their way to a parking lot on one side of the facility. From there, they could see a growing column of black smoke above the roof and, eventually, boxes inside the warehouse burning. Management instructed the group to remain on the property.

“I felt trapped, like there was nowhere for us to go,” Caceres told CBS News Sacramento.

The exit gates were not open, and workers were unable to leave the property for roughly an hour after the fire started. As smoke thickened around them, they were moved to different points inside the facility fence line but remained behind locked gates. Caceres said some employees cried, others attempted to climb over the gate, and the sounds of things popping, exploding, and glass breaking were audible throughout.

Caceres said they were told at one point that a head count would be conducted, but it never happened.

“Why did you guys hold us in here? The fire is active, and it was super hot and we were exposed to the smoke,” Caceres said. “I feel like they should have evacuated us immediately.”

In a statement on the Medline newsroom site, the company disputed that account. Medline said the Tracy facility held regular safety drills in compliance with OSHA requirements, including an emergency evacuation drill on April 15, 2026, and that its Emergency Action Plan — including head counts and muster points — was executed as designed on June 11.

CBS News Sacramento reached out to Medline for comment on Caceres’ specific account and did not receive a response.

Problematic Regulatory History, OSHA Complaints

The June 11 fire landed in the middle of an existing government investigation. Cal/OSHA confirmed it had opened a separate safety complaint inspection at the Medline Tracy facility on June 8, 2026 — three days before the fire — and said the agency would incorporate the blaze into that ongoing inspection. Cal/OSHA declined to release details about the underlying complaint while the case remains open.

The safety history at the Tracy warehouse predates the June complaint. The facility accumulated seven OSHA complaints between 2022 and the date of the fire, generating citations related to unsafe vehicle travel inside the warehouse, hazardous aisles and stairways, and insufficient exit infrastructure. Those violations resulted in fines across multiple inspection cycles.

Fire investigators from the South San Joaquin County Fire Authority have said the cause of the fire remains under investigation. Medline has committed to providing investigators and other agencies with jurisdiction full access to the site.

The Scope of Medline’s Destruction

The Medline Tracy facility served as the company’s primary distribution hub for all of Northern California, operating 24 hours a day and designed to deliver next-day service to 95 percent of Medline’s U.S. customers. The facility sat on 37 acres in the Prologis International Park of Commerce alongside Amazon, Home Depot, and FedEx operations.

Everything inside the building — the entire medical and surgical supply inventory, both AutoStore robotic systems, all administrative offices, trucks parked in the yard, and a number of employee vehicles — was destroyed.

Deputy Chief Bagley said the loss would affect medical supply distribution across the western United States, with the Tracy warehouse serving as the main distribution hub for the region. Sutter Health, which had expanded its prime vendor agreement with Medline as recently as November 2024 to cover medical-surgical, lab, and environmental services supplies, said it was monitoring the situation closely and had contingency plans in place to maintain access to critical supplies.

Medline said it activated a command center immediately on June 11 and began rerouting order lines to secondary and tertiary distribution centers, boosting regional inventory, and increasing transportation capacity to limit disruption to healthcare providers. By the following Friday, several undamaged semi-trucks were loaded and leaving the Promontory Parkway site with recoverable supplies.

Civil Liability in California Industrial Fires

When a fire on this scale is linked to failed safety systems and disputed evacuation practices, California law provides several avenues for injured or affected workers to seek civil recovery.

Premises Liability and Negligence. Under Civil Code § 1714, property owners and operators owe a duty of ordinary care to everyone lawfully on their premises. A fire suppression system that passes a January inspection and produces zero water pressure six months later — during the exact type of fire it was designed to contain — will be central to any negligence analysis. The question for a jury would be what the building owner knew or should have known about the system’s condition, and whether the failure to ensure its reliability constituted a breach of that duty.

Employer Liability for Workplace Safety. California Labor Code protections require employers to maintain safe working conditions. Employees who allege they were held on-site, exposed to toxic smoke, denied timely egress through locked gates, and subjected to conditions inconsistent with the company’s own stated evacuation plan may have grounds for claims grounded in workplace safety violations — particularly given the seven prior OSHA citations at the facility.

Toxic Exposure. The burning of lithium-ion batteries produced hydrogen fluoride gas, a highly corrosive and acutely toxic compound. Workers and surrounding community members who experienced smoke inhalation or chemical exposure during the multi-day event may be entitled to compensation for medical monitoring, treatment costs, and related harms under both negligence and toxic tort theories.

Wrongful Death. No fatalities have been reported in connection with the Medline fire. If a death were attributed to the fire or its aftermath, heirs would have standing to pursue wrongful death claims under California Code of Civil Procedure § 377.60, with damages governed by § 377.61.

Statute of Limitations. Personal injury and wrongful death claims in California are generally subject to a two-year statute of limitations under Code of Civil Procedure § 335.1, measured from the date of injury. Workers who were exposed to hazardous conditions, or community members who suffered health consequences from smoke or chemical exposure, should consult an attorney before that window closes.
