 Hi, I'm Leslie Segretti with today's tip of the day. Did you know that one quarter of all fires start during typical sleeping hours of 10 p.m. to 6 a.m., and more than one half of all fire-related deaths occur during this period? Smoke detectors do wear out. If the ones you have are more than five years old, it might be time for a new one. The latest models have updated features such as photoelectric sensors that are more sensitive to slow smoldering fires.
