Brennan Claims No Blame For Explosion

An engineering firm that was testing a Milwaukee factory's backup propane fuel system when a deadly explosion occurred says in a court filing that it wasn't to blame for the blast.

The explosion last December killed three workers and injured dozens of others. J.M. Brennan filed its response to a lawsuit by survivors of the three victims of the Falk Corporation explosion. The lawsuit claims Brennan employees allowed leaks to develop in an underground pipe that connected liquid propane tanks to boilers used to heat the factory.
