Wisconsin fire officials are asking Gov. Scott Walker's administration to expand the use of circuit interrupters in newly built homes, a step they say would prevent fires and save lives. The request comes from recommendations made last year by an advisory committee of experts. The state Department of Safety and Professional Services initially opted not to adopt that recommendation, but has not taken final action on the matter. "In all honesty, people are most likely going to die or be seriously injured as a result," said Wauwatosa Fire Chief Rob Ugaste, president of the Wisconsin State Fire Chiefs Association, at a news conference Monday. The DSPS advisory panel voted 9-1 last fall on a recommendation to require builders to install circuit interrupters in more places within new homes.
