Keene officials are urging residents to help keep fire hydrants visible and accessible this winter, warning that snow-covered hydrants can delay firefighters during emergencies when every second counts. KEENE, N.H. (MyKeeneNow) As winter weather continues to blanket the region, Keene officials are reminding residents of the critical importance of keeping fire hydrants clear of snow. The city maintains more than 1,000 hydrants, many of which can become completely buried during heavy storms, making them difficult to locate in an emergency. The Keene Fire Department and Public Works Department are asking residents and business owners to help by clearing snow away from the hydrant nearest their home or property, if it is safe to do so. City officials expressed appreciation to residents who lend a hand, noting that a few minutes of snow removal can make a life-saving difference during a fire.
