While the exact cause is yet to be confirmed, it is important to remember to clear snow off gas tanks, fill pipes, and vents. Snow or ice accumulations can cause parts of your propane system to crack or break, resulting in a gas leak. A blocked vent can cause a back-up of carbon monoxide in your home. If your tank is entirely buried, make sure to attach a brightly colored flag to the top of your propane tank so that it can be spotted easily. Never use a shovel against or on top of your tank or a vent, and never kick your tank. Only use your hands or a broom to remove snow to avoid damaging equipment. If you do smell gas, notify your gas provider and move to a safe distance.
