To prevent carbon monoxide poisoning, safety is the most important thing
01.What is gas poisoning?
What we commonly call gas poisoning is actually carbon monoxide poisoning. Carbon monoxide (CO) gas is a colorless, odorless, non-irritating toxic gas that cannot be sensed by the five senses. It can inhibit the oxygen-carrying capacity of the blood. The toxicity of carbon monoxide mainly affects the supply and utilization of oxygen. The affinity of carbon monoxide to red blood cells is more than 300 times greater than the affinity of oxygen to red blood cells, causing hypoxia in human tissues. Most people are unable to detect themselves when they are accidentally poisoned, and are often found in a coma, causing serious injuries or even death. Therefore, they are called the "invisible killer" in the family.
02. Symptoms and hazards of gas poisoning
The central nervous system is first and most severely damaged in carbon monoxide poisoning, so the symptoms are mainly neurological symptoms. The main symptoms of mild patients include headache, dizziness, nausea, vomiting, palpitations, and weakness in the limbs. In addition to symptoms of mild poisoning, moderate patients may also experience mild coma, collapse or shock, as well as pulse rate, rapid breathing, restlessness, increased muscle tone, and unsteady gait. Severe cases include deep coma, convulsions, foaming at the mouth, rapid breathing or difficulty in breathing.
03. How to deal with gas poisoning
When carbon monoxide poisoning occurs, immediately open windows for ventilation, take the patient away from the poisoning scene as soon as possible, place the patient in a place with fresh air, lie down and rest. The key is to keep the patient warm and keep the respiratory tract open, and dial 120 in time. Emergency phone number.
04. How to prevent carbon monoxide poisoning in rural areas
When using briquettes, coal blocks or charcoal for indoor heating, a chimney, small ventilation window, wind duct, etc. must be installed. Coal stoves without chimneys must be placed outdoors at night. The chimney should be cleaned of soot regularly and inspected regularly to prevent clogging of the flue.
In rural areas, everyone knows the dangers of gas poisoning, but many people suffer from gas poisoning every winter because carbon monoxide is colorless and odorless and cannot be sensed by humans. Many people like to close doors and windows to keep warm, especially at night, resulting in poor air circulation. If the chimney and flue are not cleaned for a long time and the flue is blocked; or if the wind direction changes and the flue outlet is in the upwind position, and the smoke is pushed back into the room, it will easily cause gas poisoning.
