Preparing for Severe Weather
Winter Weather Hazards
Anticipate Possible Service Interruptions
High winds, heavy snow and icy conditions can result in downed power lines or vehicle collisions with utility poles that may lead to temporary service outages for some Delmarva Power customers.
Clear Snow From Outdoor Vents
Clear snow away from appliance vents located outside your property to ensure the proper operation of heaters, water heaters, natural gas appliances and gas and electric meters.
Snow accumulation could potentially hamper the proper and safe operation of direct-vent appliances that expel products of combustion (such as carbon monoxide) to the outdoors. Many facilities have high-efficiency heaters and water heaters with exterior vents placed only 12 inches above the ground. All vented appliances require an uninterrupted supply of fresh air and a clear exhaust path in order to work properly and safely. Blowing and drifting snow can block the intake and exhaust vents, forcing appliances to automatically shut down and possibly causing serious damage.
Most appliances have automatic shut-offs that may indicate a problem with the venting system. If you are experiencing problems with direct-vent equipment or appliances, check to be sure exhaust vents are clear.
Use Caution During Snow Removal
Before you begin snow removal, carefully clear any accumulated snow from gas and electric facilities, propane and oil tank storage areas, and other phone, cable or utility facilities. Examples of equipment that should be cleared and marked include: meters, valves, regulators, piping and other facilities above ground that could possibly be hit by mechanized equipment or hand-shoveling. These areas should also be clearly marked to alert snow removal operators of their location.
As an added precaution, any snow surrounding fire hydrants or fire-fighting equipment should also be cleared and identified.
