In California, we usually hear of CO-related deaths from use of inappropriate indoor heaters or broken or improperly vented heaters. Carbon monoxide interferes with the blood s ability to transport oxygen to body organs and can result in death at even very low levels. Because it is colorless and odorless, it is impossible to detect without instruments. Symptoms of CO poisoning are similar to cold, flu, and allergy symptoms. Low levels of CO poisoning can result in headaches, lethargy, weakness, nausea, and muscle aches.
Higher levels can cause paralysis, impaired judgment, coma, and death if left untreated.
Simply removing the victim from the source may not be enough to save his or her life. If you suspect CO poisoning, it is important to get immediate medical attention and treatment. The most common source of carbon monoxide in California homes is the use of inappropriate or improperly installed heating devices. Examples of inappropriate heating devices are charcoal grills, gas barbeques, camp stoves, or any device that does not explicitly mention that it may be used indoors. If in doubt, do not use the device inside until you call the manufacturer.
