Winter vacation has arrived, and the festive atmosphere is becoming stronger. When gathering with family and friends to relax during the holiday, don't forget that there is an invisible "killer" lurking in our daily life scenes and activities - carbon monoxide. Carbon monoxide is colorless and odorless, difficult to detect, and can cause acute poisoning if inhaled in excess. The following common living scenarios and popular leisure and entertainment activities require extra vigilance: 1. Heating with charcoal fire: Use coal stoves, charcoal fires, straw, earthen beds, fire walls, etc. for heating in enclosed or poorly ventilated spaces. 2. Hot pot barbecue: In poorly ventilated restaurants or homes, use equipment such as charcoal stoves, coal stoves, and card stoves to eat or make hot pot, barbecue, or cook. 3. Cooking tea in a furnace: When cooking tea in a poorly ventilated environment, most consumers do not receive safety warnings from the merchant when purchasing the equipment themselves. 4. Wilderness camping: Use charcoal fire or a card stove to warm or cook inside a closed tent. 5. Home underfloor heating: Gas type underfloor heating is used in the home, but due to improper operation, gas leakage occurred and windows were not opened for ventilation in a timely manner. 6. Moxibustion for health preservation: In poorly ventilated health centers, the smoke from burning mugwort leaves for a long time cannot be expelled in a timely manner. 7. Greenhouse: Working for a long time in a greenhouse or greenhouse that is heated by hot air stoves, coal stoves, diesel warm air fans, etc. during winter. 8. Sleeping in the car: Sleeping in a closed car with air conditioning on, insufficient gasoline combustion when the engine is running continuously at idle, especially in poorly ventilated environments such as underground garages, is particularly dangerous. 1、 How to identify mild symptoms of carbon monoxide poisoning, such as headache, dizziness, tinnitus, blurred vision, nausea, vomiting, limb weakness, and even brief fainting; After quickly escaping from the toxic environment and breathing fresh air, the symptoms can disappear quickly. If the poisoning lasts for a long time, moderate poisoning may also cause symptoms such as facial flushing, accelerated pulse, difficulty breathing, blurred consciousness, fatigue, hallucinations, shallow coma, delayed light and corneal reflexes, etc; If rescued in a timely manner, one can quickly regain consciousness and fully recover within a few days. Severe poisoning can result in deep coma or loss of cerebral cortex, significant weakening or disappearance of various reflexes, incontinence of urine and feces, cold limbs, pale or cyanotic lips and complexion, elevated body temperature, decreased blood pressure, and respiratory depression; Severe poisoning patients have a high mortality rate, and survivors may have serious sequelae. 2、 How to self rescue or rescue others after poisoning: Firstly, cut off the source of carbon monoxide, immediately open windows for ventilation to promote air circulation, quickly close gas/gas stoves, water heater valves, pipeline gas, engines, and extinguish charcoal fires and other facilities and equipment. 2. Quickly evacuate the patient from the poisoning site and transfer them to a location with fresh and well ventilated air. 3. Loosen the collar button of the poisoned person and keep the respiratory tract unobstructed; At the same time, attention should be paid to keeping warm to prevent complications from occurring. 4. Patients should maintain quiet rest, avoid activities that increase oxygen consumption, and provide oxygen therapy as soon as possible if conditions permit. 5. For moderate to severe patients, while receiving on-site emergency treatment, immediately call 120 emergency hotline and send them to a hospital with a hyperbaric oxygen chamber for treatment as soon as possible. 6. For critically ill patients who experience respiratory and cardiac arrest, artificial respiration and cardiac compressions should be immediately administered, and they should be promptly transferred to the hospital for emergency treatment. 3、 How to prevent carbon monoxide poisoning: 1. When using coal stoves, charcoal fires, and other equipment for heating or dining indoors or in a closed environment, the fuel should be burned out, and ventilation should be carried out regularly to maintain smooth indoor air flow. 2. Install and use coal stoves, charcoal stoves, and other equipment correctly, regularly inspect stoves, maintain and clean chimneys and air hoppers, and keep chimneys and air hoppers unobstructed. When using gas, gas water heaters, stoves, and underfloor heating equipment, good ventilation should be maintained, and the usage time should not be too long. After use, check whether the valves are completely closed. 4. Regularly inspect the gas tanks, pressure reducing valves, and hoses of gas, gas water heaters, stoves, and underfloor heating equipment. If any damage, rust, or gas leakage is found, they should be replaced in a timely manner. 5. Do not use small oil and gas generators indoors, in garages, basements, etc., use them outdoors. When the vehicle is parked in the garage or basement, do not let the car engine run continuously; When the car is parked, do not leave the air conditioning on for a long time, and do not sleep in a car with doors and windows closed and the air conditioning on. 7. It is recommended to install carbon monoxide detectors indoors and regularly inspect and maintain them to ensure their normal operation. (New Society)
