Minnesota Energy Resources is reminding customers to avoid the dangers of snow and ice buildup on exhaust vents and natural gas meters. These areas often are overlooked when buried under several inches of snow.

Snow and ice accumulation on furnace vents can lead to potentially deadly carbon monoxide levels in homes. A blocked vent also can affect the performance of furnaces.

Accumulated snow and ice can damage natural gas meters, which could lead to potentially dangerous gas leaks.

The group also urged people to use caution when cleaning around meters and vents.

To avoid problems:

•Use a broom to gently brush snow off the meter.

•Avoid kicking or hitting the meter to break away built-up snow or ice.

•Always shovel away from the meter.

•Take care when using a snow thrower or plow near your meter.

•Remove icicles that may drip water onto meter.

Keeping meters clear allows Minnesota Energy employees to properly service meters in case of emergencies.

Any customer who smells a natural gas odor should leave the house immediately and call the Minnesota Energy gas emergency number at 800-889-4970.
