Energy company stresses safety measures in the winter

After the recent bout of cold and snow across the state, NorthWestern Energy has released some information on safety measures involving carbon monoxide and natural gas.

The company said in a press release that there have been several incidents involving carbon monoxide poisoning across NorthWestern’s service territory. It described carbon monoxide as a toxic, colorless, odorless and tasteless gas produced by the incomplete burning of natural gas, propane, kerosene or other fossil-fuel heat, and can result from improperly vented or malfunctioning furnaces, space heaters and other heating devices.

The threat of carbon monoxide poisoning increases significantly when homes are sealed tight in the winter months, according to NorthWestern Energy. Symptoms of such poisoning can resemble the flu and can occur quickly or after long-term exposure. Symptoms can include dizziness, confusion, shortness of breath, nausea, headaches, fainting and tightness in the chest.

Unlike carbon monoxide, the press release said, natural gas features a strong odor that is added before it is distributed to customers. If there is a strong, persistent odor similar to rotten eggs, people are advised to leave the building immediately and avoid using any electric appliances such as light switches, garage door openers and phones — including cellphones. From a safe distance, call NorthWestern Energy or 911 to report it and stay away from the building until someone from the utility or a first responder tells you it’s safe to return.

Northwestern Energy also recommends that residents check for accumulation of ice or snow around outside natural gas meters, and check natural gas appliance vents — which often are on the roof — to ensure they are clear of snow. Clearing snow and ice from meters or vents should be done carefully to avoid damaging the equipment. Heavy build-up of snow or ice, icicles falling from building eaves, or water dripping from a roof and freezing on a natural gas meter or appliance vent may disrupt the flow of natural gas or create a potentially dangerous situation inside the structure, the press release stated.

NorthWestern Energy said people who suspect carbon monoxide to be present in their home or business should immediately seek fresh air and call the company.
