The state fire marshal's office is asking Tennessee residents to inspect their smoke alarms when they change their clocks this weekend.
Commissioner Julie Mix McPeak says people should change the batteries in their smoke alarms when they change their clocks Saturday night for daylight saving time.
She also urges everyone to consider the age of their smoke alarms.
McPeak says alarms, even those that are hard-wired, should have their batteries replaced regularly and should be tested monthly to ensure they are providing the proper protection.
She says it's also important to note that any smoke alarm that is 10 years old or older should be replaced entirely.
Statistics show nearly two-thirds of all home fire deaths result from fires in homes with no smoke alarms or no working smoke alarms.
