An explosion ripped through an industrial building in Ypsilanti Township yesterday, injuring at least three people and igniting a heavy fire, sheriff and ambulance response. A thick plume of smoke rose over the commercial strip just south of I-94 as crews worked to secure the scene and check for lingering hazards. Officials urged drivers and residents to steer clear while hazmat teams moved in.
Where it happened
According to WXYZ, the Washtenaw County Sheriff's Office said the blast hit the 1200 block of James J. Hart Parkway, just west of South Huron Street and south of I-94. The site sits in an industrial and commercial pocket lined with warehouses and service businesses, which helped trigger a multiagency response.
Injuries and response
Three ambulances responded, and a Huron Valley Ambulance spokesperson told reporters that two people were transported to hospitals in stable condition while a third was treated at the scene, per ClickOnDetroit. Hazmat teams were brought in to assess any remaining risks and assist with utility shutoffs and air-quality checks.
Cause and investigation
Investigators have not yet determined what triggered the explosion. Metro Detroit News reported that the cause remains unknown as crews continued working at the site. Fire officials and sheriff's investigators typically coordinate with utility companies and state inspectors in incidents like this while they secure the structure and document damage.
Why it matters
Explosions in industrial or mixed-use commercial buildings can throw debris across streets, compromise nearby structures and create hazardous conditions that keep emergency crews on scene for hours. Michigan has seen similar incidents in recent years, including a March 2025 Detroit building blast that left multiple people injured. That event required coordinated hazmat, structural and utility responses, underscoring how complicated these scenes can become when building systems or stored materials are involved, per Firehouse.
What residents should know
Authorities are asking people to avoid the immediate area around James J. Hart Parkway and to follow local media and official channels for updates as the investigation continues. This story will be updated as officials release more information on injuries, road closures and the cause of the blast.
