Cold-weather firefighting increases the risks of conditions such as hypothermia, so extra measures should be taken to avoid problems. Multiple layers of light, loose-fitting clothing are recommended, with particular focus on potentially exposed areas such as the hands and head. You should also drink plenty of fluids. Any suspected cold-related conditions in yourself or crew-members should be reported immediately. Hypothermia can occur even at relatively mild temperatures when exposure is prolonged. Symptoms include bouts of shivering, drowsiness, confusion, muddled thinking, impaired vision, shallow breathing, and loss of coordination.
