MADISON, Wis. (AP) – The Wisconsin Department of Military Affairs says the switch to daylight saving time provides a good opportunity for homeowners to make a number of safety checks.  Clocks get moved back an hour Saturday night.  The DMA says that is a good time to check and replace batteries as needed on home smoke detectors and carbon monoxide detectors.  The DMA also recommends that every home have a basic emergency kit with supplies such as food and water to last you and your family at least three days. Other items like a battery powered or crank radio, flashlights and first aid kit are also recommended.   Other disaster survival tips are listed on the website: readywisconsin.wi.gov.
