VIDEO: A state proposal to lower requirements for fire prevention devices in new buildings in Wisconsin sparked a heated debate at a public forum hosted by Wisconsin Department of Safety and Professional Services in Eau Claire. One of the proposed changes is to reduce the number of buildings requiring a sprinkler system. The current law requires sprinklers for a building with more than three units. The new proposal says only buildings with more than 20 units in a building need a sprinkler system. Members of the Wisconsin State Fire Chief's Association said sprinklers could save lives and prevent property damage. Chief David Bloom said Monday night's fire in Sun Prairie could have been prevented if the building had a sprinkler system. That fire displaced 20 people.
