When was the last time you changed the batteries in your smoke alarm and carbon monoxide detector? When was the last time you tested them? As everyone turned their clocks forward last weekend, the U.S. Consumer Product Safety Commission (CPSC) recommended consumers also change their batteries and test their devices.
The CPSC recommends that batteries on both smoke alarms and carbon monoxide detectors be changed once a year. They also recommend testing both devices monthly.
Since carbon monoxide is a colorless, odorless, poisonous gas, it is important for consumers to have carbon monoxide detectors as they can’t see or smell the gas.
