The New Fairfield Volunteer Fire Department is issuing some warnings and reminders to people taking part in outdoor winter activities like fishing and skating. Members say venturing out onto ice-covered water calls for caution because conditions can vary from area to area. The cautioned never to drive a vehicle, snowmobile or all-terrain vehicle onto ice. In addition to the risk of drowning, an individual falling through ice may become victim to hypothermia, so it's recommended that a life jacket is worn. In addition to reducing reaction times, alcohol lowers the body's internal temperature and increases the chances of suffering hypothermia so it's alcohol avoidance is recommended.
