Never turn on a water heater unless the tank is full. Plumbing can freeze when power is lost during cold weather periods. Drain pumps, supply lines, water heaters, boilers, and traps in drains of tubs, sinks, commodes, washing machines, and dishwashers. To avoid major flooding when temperatures rise, turn off supply lines to outside spigots. You should have a contingency plan that always includes an alternate power source for the device and relocating the person.
Trees are the primary cause of power outages in Milwaukee County.
Power companies have regularly scheduled programs for trimming trees. Use fireplaces and wood-burning stoves with care, and always supervise them when burning. Make sure the fireplace is in proper working condition and has been inspected before use. Wear layers of clothing, including sweaters and coats, which entraps warm air and helps to maintain body heat for longer periods. For homes with natural gas heaters, keep meters and vents clear of ice and snow.
