Daylight Saving time ends Sunday, November 7, and with that, Summit County’s fire districts are encouraging citizens to change their smoke-detector and carbon-monoxide batteries.”We want to remind residents that one easy step can help save their lives and the lives of those around them,” said RWB Fire District Deputy Chief Jay Nelson. “Use the extra hour this weekend to remind your friends, family and neighbors to take safety into their hands and make a difference.”Even “hard-wired” smoke detectors that are plugged in to the home’s electrical supply typically have a 9-volt backup battery to keep the detectors operating in case of a power outage. Often they will “chirp” when the batteries are dying – that means to change the batteries, don’t disconnect or disable the devices! When changing batteries, make sure to test the audible siren by pushing the button; check that the vents are clean and not clogged with dust; and check the manufacture date. Typically, smoke detectors should be replaced every 10 years, and carbon-monoxide detectors should be replaced every five years.Both smoke and carbon-monoxide detectors should be placed on every level of the home as well as inside every bedroom. Follow the manufacturer’s instructions for proper installation.In addition to changing smoke and carbon monoxide detectors, the Copper Mountain Fire, Lake Dillon Fire and Red, White & Blue Fire districts encourage families to plan and practice a home-escape plan.
