A medical supply warehouse was destroyed after it went up in flames and prompted evacuations of neighboring buildings Thursday afternoon in Tracy. The massive blaze, which was one of several fires reported on the 5700 block of Promotory Parkway in the San Joaquin County city, could be seen from a cross the Bay Area region. Firefighters pointed to water supply challenges and weather conditions as the reason the blaze spread quickly and engulfed the approximately 1 million-square-foot facility. No injuries have been reported, officials said. Officers were also on scene assisting with evacuations and directing traffic, according to police. A police spokesperson said explosions can be heard at the warehouse as flames continued to burn. Police have also told residents impacted by the smoke to close their windows and to shelter in place. Medline Industries warehouse destroyed in Tracy fire NBC Bay Area’s SkyRanger showed the gutted building belonged to Medline Industries. The company has a distribution center located in the area. Medline provided the following statement: “Medline can confirm a fire is occurring at our Tracy, California distribution facility. All Medline employees and on-site personnel are accounted for. The safety and well-being of our employees is our top priority. We are coordinating closely with local authorities and first responders as we assess the fire’s impact and will share more details as they become available.” Large blaze prompts other warehouses, including FedEx building, to evacuate in Tracy Tracy Mayor Dan Arriola said there was no mandatory evacuations in place due to the blaze, but added several nearby businesses in the area self-evacuated. Police said all warehouses southwest of the Medline building have been evacuated: “We are aware of multiple fires in the area and are coordinating with personnel from South San Joaquin County Fire Authority to assess conditions and address any evacuation needs if they arise. Out of an abundance of caution, public safety personnel are present in the Tracy Hills area; however, there is currently no threat to residents. Personnel are assisting with traffic control and monitoring conditions.” The neighboring warehouse evacuated during the blaze is FedEx’s Tracy hub. The company provided the following statement: “We are aware of a building fire that started at a neighboring location before spreading to the Tracy hub. All team members have been safely evacuated and are accounted for. As this is an active situation, further questions should be directed to the local authorities.” FedEx later said in a statement the blaze did not reach its facility. Firefighters also helped keep flames away from other buildings by aggressively attacking the fires. How did the fire spread so quickly in the large Tracy warehouse? The blaze was reported just before 1 p.m. When firefighters arrived, they found a “rapidly developing fire involving the roof” of the warehouse. Officials said firefighters faced water supply challenges with no water pressure in the building. In addition, sprinklers installed in the warehouse were not working. “Early suppression efforts were hampered by a failure of the building’s private fire water system, which significantly impacted initial firefighting operations,” the City of Tracy said in a statement. “Combined with high winds, low humidity, and elevated temperatures, the fire quickly extended from the roof into the interior of the facility.” A cause of the fire is still under investigation, police said. Warehouse fire sparks mutual aid response In addition to Tracy firefighters and Cal Fire crews, several fire departments from the Bay Area responded to the massive warehouse blaze.

The Contra Costa County Fire Protection District sent over two engines to help provide coverage in the city.
