What is gas poisoning?
Gas poisoning usually refers to:Carbon monoxide poisoning。Carbon monoxide is colorless and odorless, lighter than air, and easily combustible, with a blue flame when burned. If the carbon monoxide content in the air reaches 004%－0.06% of the time, it can poison people.
A common cause of gas poisoning
The use of gas or liquefied petroleum gas for cooking in a closed room produces a large amount of carbon monoxide accumulation indoors due to poor ventilation and insufficient oxygen supply.
If urban residents use liquefied petroleum gas, if the pipeline leaks and the switch is not tight, it can cause a large amount of gas overflow, causing poisoning.
Use of gas water heater, poor ventilation, and long bathing time.
Sleeping with the air conditioner on and without the windows in a car without the engine turned off may cause poisoning.
When using air conditioners in small rooms, we must pay attention to interchanging with the outside air, otherwise it is easy to produce harmful gases and endanger health.
Misunderstandings about gas poisoning
Only burning coal can cause poisoning. All carbon-containing fuels, such as gasoline, kerosene, charcoal, etc., can produce a large amount of carbon monoxide when they cannot be completely burned due to lack of oxygen, so they can also cause gas poisoning.
Thinks that a foul smell is carbon monoxide. Some low-quality coal has a foul smell when burned, which can cause headaches and dizziness. Carbon monoxide gas is colorless and odorless, and is produced by incomplete combustion of carbon. Some people think that there is no carbon monoxide poisoning if there is no smell of slag in the house, which is completely wrong.
It is thought that putting a basin of water by the stove can prevent carbon monoxide poisoning. It has been scientifically confirmed that carbon monoxide is insoluble in water, and the key to preventing poisoning is not to close the doors and windows too tightly, and to keep the chimney unobstructed.
The absence of soot in the room does not cause poisoning. Carbon monoxide is a colorless, odorless gas, and the absence of soot in the room does not mean that there is no carbon monoxide, and carbon monoxide poisoning occurs unknowingly.
Installing an exhaust fan does not cause carbon monoxide poisoning. Many people use old exhaust fans in their homes, or the exhaust fans are too small and not installed high enough. Then, if the gas is not discharged smoothly, it will also cause poisoning.
Symptoms associated with gas poisoning
Mild poisoningYou will feel dizzy, headache, dizziness, and general fatigue, and if you can open the window for ventilation and breathe in fresh air, the symptoms will quickly reduce and disappear.
Moderately poisonedSymptoms such as excessive sweating, irritability, unsteady walking, paleness, confusion, always feeling awake, drowsiness and fatigue can occur.
Severely poisoned peopleConfusion, trismus, twitching of the whole body, incontinence, peach-red complexion and lips, rapid breathing and pulse, increased blood pressure, irregular heartbeat. Extremely critically ill patients can continue to be in a deep coma, with a weak pulse, irregular breathing, a drop in blood pressure, and a high fever of 40, at which time life is in danger and the case fatality rate is high. Even if you are lucky enough to survive, you will still have serious sequelae.
How to prevent gas poisoning
Keep your device safe
Install the gas water heater properly. Gas water heaters are strictly forbidden to be installed in bathrooms, and should be installed in ventilated places such as balconies. The installation of gas water heaters should be carried out by professionals with gas installation qualifications and experience in accordance with the regulations, so as not to leave the hidden danger of carbon monoxide poisoning.
Use a gas water heater properly. The use of gas water heater should not be too long to take a bath, pay attention to maintain ventilation, it is strictly forbidden to use it for a long time, and repair it in time when the water heater is found to be faulty.
Regular check-ups. Ask a professional to inspect the gas pipes, stoves, gas appliances switches, leather pipes, etc., to prevent gas leakage.
Pay attention to open windows for ventilation
When using gas appliances for a long time, be sure to open the windows for ventilation to ensure air circulation.
If coal is used for heating, the coal stove should not be placed in the bedroom, and the doors and windows should not be closed tightly when the stove is used for heating, and it must be fully ventilated.
Before going to sleep, make sure that the coal is completely burned out and extinguished, and check whether the gas valve is closed, otherwise it is more dangerous to have gas poisoning in your sleep.
Do not eat charcoal hot pot or light charcoal brazier in a closed room.
Do not rely on the engine to heat the cabin for a long time in a closed compartment, and do not sleep in the compartment when the engine continues to burn.
If you feel dizzy, heavi, 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.
First aid for gas poisoning
Once carbon monoxide poisoning is detected, the first step is to call 120 for emergency services** and carry out on-site rescue of the poisoned person.
If you find that you have symptoms of poisoning, you can temporarily walk (crawl) out of the poisoning scene, breathe fresh air, and call others for help.
When you find that someone else has been poisonedThe window should be opened immediately, the poisoned person should be carried away from the scene to a ventilated place, the poisoned person should be unbuttoned, so that he can breathe smoothly, pay attention to keeping warm, and send him to the hospital. At the same time, turn off the gas stove switch or lift the coal stove outside.
If the poisoned person has vomiting symptoms, the head of the poisoned person should be tilted to one side, and the secretions in the mouth and nose should be cleaned up in time.
If you have respiratory and cardiac arrest, immediately perform artificial respiration and chest compressions, and be sent to the hospital as soon as possible. Particular attention should be paid to the fact that rescue measures should not be interrupted during the transport of patients.
