In the cold winter, some people like to use stoves, charcoal fires, coal fires to keep warm, and some people like to sit around the stove to make tea, barbecue, eat soup pots, eat hot pots, etc., without paying attention to open windows for ventilation, which is easy to cause carbon monoxide poisoning accidents.
What conditions can trigger carbon monoxide poisoning?
1.In winter, coal stoves are used for heating, doors and windows are closed, and smoke exhaust is poor.
2.The coal stove does not have a chimney or the chimney is blocked.
3.The chimney is facing the tuyere, and the gas flows into the chamber in reverse.
4.There is no ventilation in the room.
5.Leakage of liquefied cooktops, leaks of gas pipes.
6.Use a gas water heater and build it in the same house as the bathroom.
7.Turn on the air conditioner when parking for long periods of time.
Locations where carbon monoxide poisoning is most likely to occur
1 Home kitchen with poor smoke exhaust.
2 A poorly ventilated room with charcoal, gas, or coal for cooking.
3 The water heater is placed in an enclosed space.
4 Inside a car with an air-conditioned air.
What are the dangers of carbon monoxide poisoning?
1.Carbon monoxide is the most common asphyxiating gas because it is colorless, odorless, odorless, and non-irritating, and is not easy to detect even if it is poisoned.
2.Deaths from carbon monoxide poisoning have been devastating to many families, and the scars of losing family, loved ones, and happiness have cast a shadow over their lives and their families' lives. In addition, some patients with gas poisoning may develop late-onset encephalopathy after a 2-60 day false recovery period, including dementia, parkinsonism manifestations, hemiplegia, urinary and urinary incontinence, aphasia or blindness, or leave serious sequelae, affecting prognosis and quality of life.
Be alert when these symptoms occur
Mild poisoning: manifested as early symptoms of poisoning, headache, dizziness, palpitations, nausea, vomiting, weakness of the limbs, and even brief fainting. At this time, if you can open the window in time to ventilate and inhale fresh air, the symptoms will be quickly reduced and disappear.
Moderate toxicity: on the basis of mild symptoms, excessive sweating, irritability, arrhythmias, collapse, or coma may occur.
Severe poisoning: On the basis of moderate poisoning, the patient has a deep coma, loss of various reflexes, incontinence, cold limbs, decreased blood pressure, shortness of breath, and even death.
How can I prevent carbon monoxide poisoning?
1.Ventilation is key. In the coal stove at home, you must keep the windows open for ventilation, or set up vents, so that the air can be kept circulating, and the danger will be reduced.
2.The connections of coal furnaces in rural households must be sealed to prevent gas leakage, and the flue must be cleaned in time to prevent the flue from being blocked.
3.In-line water heaters are prohibited in residents' homes, and attention should be paid to ventilation when bathing.
4.When the car is idling, do not turn on the air conditioner for a long time, in the confined space where the air conditioner is turned on, toxic gases will accumulate, which will also cause carbon monoxide poisoning.
What to do if someone has carbon monoxide poisoning?
1.The poisoned person should be allowed to leave the poisoned environment as soon as possible, and the doors and windows should be opened immediately to circulate the air and keep warm. It is forbidden to use electric lights, mobile phones, candles, etc. when air circulation is not ensured to prevent high carbon monoxide concentrations and cause them.
2.Unbutton the clothes of the poisoned person, remove mouth and nose secretions, make them breathe freely, and rest quietly to avoid increasing the burden on the heart and lungs and increasing oxygen consumption after activities.
3.If the poisoned person is confused, the rescuer should check the patient's breathing, pulse, and blood pressure in the shortest possible time, and carry out emergency treatment according to these conditions.
4.If the poisoned person's breathing and heartbeat are stopped, artificial respiration and cardiac compressions are performed immediately.
5.Call the 120 emergency service and wait for the emergency doctor to arrive at the scene to treat the patient.
Pay attention to these details in life
In addition to the possibility of carbon monoxide poisoning in coal stove heating, in daily life, the following prevention points are specially reminded:
1.There should be safety settings (such as chimneys, small ventilation windows, air ducts, etc.) when using coal fires indoors, and the installation of coal stove chimneys should be reasonable, and coal stoves without chimneys should be placed outdoors at night. At the same time, install carbon monoxide alarms indoors.
2.To use gas water heaters correctly, do not use obsolete gas water heaters, such as in-line water heaters and flue water heaters, both of which are prohibited from being produced and sold by the state; Do not use gas water heaters that have expired in service; It is best to ask a professional to install the water heater, and it is not allowed to install, dismantle, or modify the gas appliance by yourself; When taking a bath in winter, do not close the doors and windows of the bathroom, and do not take a bath for too long.
3.When driving, don't let the engine idle for a long time; When the car is stopped, do not turn on the air conditioner for too long; Even when driving, you should open the windows frequently to allow convection of the air inside and outside the vehicle. If you feel unwell, stop and rest immediately; If you feel dizzy, heaky, or weak in your limbs while driving or riding in an air-conditioned vehicle, you should open the window in time to breathe fresh air.
