...and not just your clocks. (not going where you thought I might?) Seriously, use the time change tonight as a reminder to change out the batteries in your smoke detectors and CO detectors, then test each of these devices. The National Fire Protection Agency recommends that you replace any device that is ten or more years old. If in doubt, change them out. If the plastic has turned yellow like an old computer, change 'em out. Starting around $10 each, these are very cheap insurance against waking up dead! Last spring we had a residential structure fire right next door, and the occupants didn't have functioning detectors. They were extremely lucky to escape with minor smoke inhalation injuries. Their three pets were not so lucky. While you are at it, check your extinguishers, flashlights and hopefully stock a Chimfex in/near your hearth room(s). Cheers!
