(BPT) — Few areas of the country are immune to natural disasters or severe weather. Whether you live in a hurricane zone or face icy winters, it is important to prepare your home and family to weather the storm and know the potential health and safety risks that may arise in emergency situations.

Beyond inconvenience, widespread and long-term power outages resulting from storms raise a much more serious concern: carbon monoxide poisoning. While the poisonous gas can come from any fossil fuel-burning appliance or vehicle, the risk posed by generators is of particular concern because of this year’s devastating storm season.

“Simple preparation, along with an understanding of the risks of CO, are key factors for protecting your home and loved ones both during storm season and throughout the year,” said Tarsila Wey, director of marketing for First Alert. “The risk of CO can occur anytime — not just during emergencies — which is why installing and regularly testing CO alarms are an integral part of any home safety plan.”

What is CO?

Often dubbed “the silent killer,” the gas is colorless and odorless, making it impossible to detect without a CO alarm. According to the Journal of the American Medical Association, CO poisoning is the No. 1 cause of accidental poisoning in the United States and is responsible for an average of 450 deaths each year.

CO poisoning is notoriously difficult to diagnose — often until it’s too late. Symptoms mimic those of many other illnesses, and include nausea, headaches, dizziness, weakness, chest pain and vomiting. In more severe poisoning cases, people may experience disorientation or unconsciousness, or suffer long-term neurological disabilities, cardio-respiratory failure or death.

Sources of CO may include, but are not limited to, generators, heaters, fireplaces, furnaces, appliances or cooking sources using coal, wood, petroleum products or other fuels emitting CO as a by-product of combustion. Attached garages with doors, ductwork or ventilation shafts connected to a living space also are sources of CO.

What should you do?

The National Fire Protection Association recommends installing CO alarms on every level of the home, including the basement, and within 15 feet of all sleeping rooms. These alarms are the first line of defense against CO poisoning. Checking alarms regularly and following manufacturer instructions for alarms and all home equipment play an equally vital role.

In case of power outage, never use a generator indoors. Portable electricity generators must be used outside only and should never be used in a garage or in any confined area that can allow CO to collect. When running a generator, be sure to remain 15 to 20 feet away from the outside perimeter of the home and be careful to follow operating instructions closely.
