Daylight saving time comes to an end Sunday morning at 2 a.m. That means it’s time to fall back and set your clocks back one hour.In addition to the time change, McMinnville Fire Chief Keith Martin wants to remind residents to change the batteries in their smoke alarms and carbon monoxide detectors this weekend when they set back their clocks.“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,” Martin said. “Use the extra hour we gain this weekend to make sure your home and family are fire-safe.”Many fatal fires occur at night while the victims are sleeping. The smoke and toxic gases generated by a fire can cause people to sleep more deeply, narrowing the chances of surviving a fire.
