VENANGO CO., Pa. (EYT) — Daylight saving time begins at 2:00 a.m. this Sunday morning, and that means more than just changing your clocks.

In a press release issued by acting Pennsylvania State Fire Commissioner Bruce Trego reminded PA residents to change the batteries in their smoke alarms and carbon monoxide detectors when time “springs forward” this Sunday.

“The batteries should be changed periodically, and a good way to remember is that is to do it when you change your clocks,” said Trego. “Practicing your home fire escape plan with your family all in the same weekend is a great way to keep your loved ones safe.”

Though most newer models of smoke alarms have long-lasting batteries that do not need to be replaced, thousands of people still use models that depend on standard batteries that need to be replaced on a regular basis.

According to Trego, worn or missing batteries are the most common cause of a smoke alarm or carbon monoxide detector malfunction, and, if they are functioning properly, smoke alarms cut the risk of dying in a home fire in half. Changing the batteries at least once a year is one of the simplest, most effective ways to prevent tragic deaths and injuries.

Carbon monoxide detectors are also every bit as important as smoke detectors. Often called “the silent killer,” carbon monoxide is an odorless, colorless, tasteless gas that can incapacitate victims before they’re even aware they’ve been exposed. Sources of carbon monoxide can include wood-burning fireplaces and stoves, gas-fired appliances, grills, and motor vehicles.

Symptoms of carbon monoxide poisoning are often mistaken for the flu and include nausea, headaches, dizziness, disorientation, and fatigue.

Whether they are newer, long-lasting models or models using regular batteries, both smoke and carbon monoxide detectors should be tested regularly.

The beginning of Daylight Savings Time is also a good time for families to take time to review and practice their home evacuation plans.

Remember, when you go to change your clocks, there are other yearly updates that can be vital to keeping your family safe.
