Safety Tips
- Have your home heating systems (including chimneys and vents) inspected and serviced annually by a trained service technician.
- Never use portable generators inside homes or garages, even if doors and windows are open. Use generators outside only, at least 20 feet away from homes with the exhaust facing away.
- Never bring a charcoal grill into the house for heating or cooking. Do not barbeque in the garage.
- Never use a gas range or oven for heating.
- Open the fireplace damper before lighting a fire and keep it open until the ashes are cool. An open damper may help prevent build-up of poisonous gases inside the home.
- Install battery-operated CO alarms or CO alarms with battery backup on every level of the home and outside sleeping areas. Interconnected CO alarms are best; when one sounds, they all sound.
Know the Symptoms of CO Poisoning
Because CO is odorless, colorless, and otherwise undetectable to the human senses, people may not know that they are being exposed. The initial symptoms of low to moderate CO poisoning are similar to the flu (but without the fever). They include:
- Headache
- Fatigue
- Shortness of breath
- Nausea
- Dizziness
High level CO poisoning results in progressively more severe symptoms, including:
- Mental confusion
- Vomiting
- Loss of muscular coordination
- Loss of consciousness
- Ultimately death
Symptom severity is related to both the CO level and the duration of exposure. For slowly developing residential CO problems, occupants and/or physicians can mistake mild to moderate CO poisoning symptoms for the flu, which sometimes results in tragic deaths. For rapidly developing, high level CO exposures (e.g., associated with use of generators in residential spaces), victims can rapidly become mentally confused, and can lose muscle control without having first experienced milder symptoms; they will likely die if not rescued.
