A hazardous material incident involving a tank rupture sent New Berlin firefighters to 2550 S. 170th Street early Sunday, with two engines on scene and the city's emergency management office arriving to help manage the response. Crews estimated they would need roughly two more hours of work time to handle the situation, according to an incident alert posted by the New Berlin Fire Department.
The address is the corporate headquarters and manufacturing site of Sharpe Products, an ISO 9001:2015-certified custom tube bending, pipe bending, and laser cutting facility, according to the company's own site information. The New Berlin Fire Department said in its alert that the City of Waukesha Special Services team was being contacted for hazardous materials response support, a call that brings in the county's dedicated technician-level hazmat unit. That regional team, based out of Fire Station 5, is contracted by Waukesha County to provide countywide hazardous materials response and keeps 36 personnel trained to the technician level for 24/7 coverage of technical rescue and hazmat operations, per the City of Waukesha.
A Second Major Call in 48 Hours for New Berlin Crews
The tank rupture comes just two days after New Berlin emergency responders and the same Waukesha Special Services team completed an extended rescue at Denali Ingredients on Ryerson Road, freeing a worker who had become trapped in machinery. That August 14 incident involved an adult male worker who was extricated in serious condition after nearly two hours, as reported by FOX6 News Milwaukee. Hoodline covered that hours-long machinery rescue at the time.
Back-to-back major incidents within 48 hours mark an unusually intense stretch for New Berlin's emergency services, which rely on the New Berlin Fire Department's combination staffing model of full-time and part-time firefighters and paramedics to scale up during resource-intensive calls, per the City of New Berlin. Sharpe Products itself has operated at the New Berlin site since 2002, when it purchased an initial 51,000-square-foot facility, later expanding in 2015 with an additional 38,000-square-foot building in the city, according to the company's own history.
What Remains Unclear About the Ruptured Tank
The exact substance stored in the ruptured tank, what caused the container to fail, and whether any material escaped into storm drains or soil have not been disclosed in the fire department's alert. It is also not yet known whether the Wisconsin Department of Natural Resources has been formally notified of the incident.
Under Wisconsin's Spills Law, codified at Wisconsin Statute § 292.11, any individual or entity that possesses or causes the discharge of a hazardous substance must immediately report it to the DNR through a 24-hour hotline, with violations subject to daily civil penalties ranging from $10 to $5,000, according to the Wisconsin Department of Natural Resources. Fire department personnel using hazardous substances while performing official public safety duties are exempt from those statutory penalties under a separate provision of the same law, though they remain obligated to report any environmental chemical releases resulting from their response operations, the agency notes. Separately, entities responsible for a hazardous substance release, or property owners affected by one, are required under Wisconsin Administrative Code Chapters NR 700 through 799 to contain, clean up, and restore contaminated soil, water, and other media regardless of the volume involved.
New Berlin has dealt with hazmat calls before. In March 2023, local hazmat teams responded after an estimated 70 gallons of gasoline spilled during a semi-truck delivery at a gas station near Calhoun and Greenfield roads, entering the municipal stormwater system and a nearby creek, as reported by CBS 58. That earlier spill required specialized cleanup equipment to contain. New Berlin's industrial base is substantial, with roughly 1,135 registered businesses and more than 1.6 million square feet of commercial and industrial real estate concentrated in the city's eastern Waukesha County industrial parks, according to city figures.
