6 Symptoms of Carbon Monoxide Poisoning Carbon monoxide poisoning has many symptoms. However, some symptoms are very similar to flu-like symptoms, the effects of intoxication, or drug usage. In many CO cases, people feel ill and stay home to rest. This only compounds the CO poisoning because they stay in the home where CO is present. As CO levels rise, the symptoms become more extreme. At low levels people will suffer headaches and mild nausea. At higher levels unconsciousness, heart failure, and even death can occur. The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household. Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as “flulike” symptoms). Medium Exposure: Severe throbbing headache, drowsiness, confusion, fast heart rate. Extreme Exposure: Unconsciousness, convulsions, cardio-respiratory failure, death. Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Also, young children, the elderly, and household pets may be the first affected by CO poisoning. The important factor with any CO poisoning, however, is time. At high levels, CO can cause death in just minutes. At lower levels, it could take from hours to days of constant CO exposure to have the same life-threatening effect. The chart below illustrates the symptoms of CO poisoning by concentration of CO and its effect over time. Slight headache within 2-3 hours. Frontal headache within 1-2 hours. Headache,dizziness and nausea within 20 minutes. Death within 2 hours. Dizziness, nausea, and convulsions within 45 minutes. Insensible within 2 hours. Headache,dizziness and nausea within 5-10 minutes. Death within 30 minutes. Death in less than 3 minutes. Headache,dizziness 1-2 minutes. Death in less than 15 minutes. | | | | | | | | | | | | | 0 100 200 300 400 500 600 700 800 900 1000 1100 1200 Concentration of CO in air (ppm) Conditions That Can Cause CO Levels To Change The following conditions can result in transient CO situations in the home: 1) Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient conditions, such as: i) Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). ii) Negative pressure differential resulting from the use of exhaust fans. iii) Simultaneous operation of several fuel-burning appliances competing for limited internal air. iv) Vent pipe connections vibrating loose from clothes dryer, furnaces, or water heaters. v) Obstructions in or unconventional vent pipe designs which can amplify the above situations. 2) Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.). 3) Temperature inversions which can trap exhaust gasses near the ground. 4) Car idling in an open or closed attached garage, or near a home. Home Safety Tips Many CO poisonings are caused by equipment failures due to poor maintenance, product defects, and damaged parts. The following is a list of safety tips to help prevent CO poisoning within your home: 7 Home Safety Tips cont. 1. Have all fuel-burning appliances inspected and cleaned yearly by a qualified service technician. The furnace, water heater, and stove are some of the leading sources of CO in homes. 2. Clean fireplace vents and chimney regularly. A blocked chimney could cause a backdraft of CO into the home. Do not cap chimney. This will cause a backdraft of CO into the home. 3. Do not cap or cover a drafthood or exhaust vent to any appliance. This will trap dangerous CO inside the house. 4. Do not “close off” or “confine” your fuel-burning appliances in a closed area. They need plenty of ventilation to operate properly. 5. Do not use liquid propane (LP) or charcoal grills indoors. 6. Do not operate any gasoline-powered equipment indoors. 7. Allow for plenty of ventilation when using a kerosene heater. Do not use in small areas. Preventative maintenance, common sense, and a CO detection device are some of the best solutions to preventing CO poisoning. However, a dangerous situation can happen to anyone at any time. The following list illustrates some danger signs of CO presence. 1. Soot and dirt build-up seeping out of chimney or other exhaust vents. 2. A mostly yellow, rather than clear blue, burner flame or pilot flame in gas appliances. 3. A draft of air coming from appliance, chimney, or vents. 4. If you have flu-like symptoms or suspect CO poisoning, seek medical assistance immediately.
