Daylight Savings time is a great time to replace your smoke alarm batteries.
You can prevent tragedies simply by testing and maintaining your smoke alarms and practicing a fire escape plan. All smoke alarms in your house should be tested once a month, and their batteries replaced annually. Every family should develop a fire escape plan and practice it at least twice a year. The U.S. Consumer Product Safety Commission (CPSC) recommends these measures because working smoke alarms and a fire escape plan will increase your protection in case of a fire. http://www.cpsc.gov/CPSCPUB/PUBS/5077.html
