We frequently hear of CO related deaths here in California, usually from use of inappropriate indoor heaters or broken or improperly vented heaters. Carbon monoxide blocks the blood's ability to transport oxygen to the internal organs and can result in death at even very low levels. It is a colorless, odorless gas, making it impossible to detect without instruments. Symptoms of carbon monoxide poisoning are similar to colds, flu, and allergies. Low levels of carbon monoxide poisoning result in headaches, lethargy, weakness, nausea, and muscle aches.
Higher levels cause paralysis, impaired judgment, coma, and death if left untreated.
Simply removing the victim from the source may not be enough to save the life. If you suspect CO poisoning, it is important to get medical attention and treatment without delay. The most common source of carbon monoxide in California home is the use of inappropriate or improperly installed heating devices. Examples of inappropriate heating devices are charcoal grills, gas barbecues, campstoves, 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.
