The daylight saving time switch is also a good time to check your smoke detectors.
The Consumer Product Safety Commission reminds Americans to make sure their smoke detectors are working.
This year, it is a warning that comes with a fresh reminder of just what can happen otherwise.
Earlier this week, eight children and an adult died in a fire in their home in the Bronx, New York.
Authorities say the home had two smoke alarms, but that the batteries were missing.
The CPSC and the US Fire Administration are also urging people to take a fresh look at their family's fire escape plan.
