Residents are being reminded by the Berkeley Heights Fire Department of the increased risk of carbon monoxide exposure due to the return of extremely cold temperatures. Carbon monoxide protection is particularly crucial as households depend more on furnaces, space heaters, fireplaces, and generators. The hazardous gas known as carbon monoxide, or CO, is colorless, odorless, and invisible. Installing CO alarms on each floor of the house and close to sleeping areas, testing them once a month, and changing the batteries as necessary are all advised by fire officials. Additionally, residents should avoid using barbecues, generators, or other fuel-burning appliances indoors or in garages and keep vents and flues free of snow and ice. If a carbon monoxide alarm sounds, occupants should move outside to fresh air immediately and call 911. Taking these precautions can help protect families during the winter heating season.
