Firefighters respond to a fire Friday afternoon at Humane Manufacturing, 1350 Venture Drive, Janesville.


A Janesville Fire Department official said a fire in storage silos led to an explosion Friday afternoon at Humane Manufacturing on Janesville’s south side.

One man was hospitalized in the incident, according to a Janesville Fire Department report.

Rock County dispatch supervisors reported a fire with burning silos at Humane Manufacturing, 1350 Venture Drive, at 12:06 p.m.

“The initial arriving JFD engine company reported that the tops had blown off two of the silos,” the report states.

The silos contained ground rubber, the report states. The company produces rubber mats and flooring using recycled rubber, according to its website.

The factory had smoke inside but no fire. Firefighters remained on scene for about three hours as they put out the fires in the silos, according to the report.

The report said the cause was still under investigation, and a damage estimate was not immediately available.

A large piece of metal, probably from one of the silos, was seen on the roof of the factory Friday.

Just to the east, at least one of two metal silos painted with red and white stripes to look like American flags appeared to be missing its top. Both the silos, part of a cluster of a half-dozen metal storage structures, appeared charred.

Thick, black smoke was pouring from the top of one of the silos shortly after 12:30 p.m. Fire crews from several departments used a ladder truck equipped with a water hose to knock down the fire in the silo.

A Humane Manufacturing plant property manager on site declined to comment.

Two Humane employees who asked not to be identified because they aren’t authorized to comment said they heard a “loud boom” coming from the direction of the silos.

Humane Manufacturing is listed on the Hendricks Holding Co. website as part of the holding company’s portfolio.
