More than two dozen Cedar Falls public safety personnel practiced dousing fires on two vacant flood-buyout houses on Roosevelt Street in the Cedar City area Wednesday. The crew included both full-time firefighters and police trained as public safety officers. It was the largest training exercise yet in which public safety officers and firefighters worked together. “It’s really been great,” Fire Chief John Bostwick said. “We have career firefighters teaching a lot. And the public safety officers who have some experience are teaching the new ones. They are absorbing a heck of a lot.” Such training and firefighting will become more prevalent in the future. All Cedar Falls police officers hired after July 1, 2016, are required to be cross-trained in firefighting skills. Public Safety Director Jeff Olson said officers typically are cross-trained within three years of hire and usually sooner.
