Gas poisoning usually refers to carbon monoxide poisoning. Carbon monoxide is colorless and tasteless. It is lighter than air and easy to burn. It is a blue flame when burning. If the content of carbon monoxide in the air reaches 0.04% ~ 0.06%, people can be poisoned. When it is mixed with air up to 12.5%, it may also produce explosion. Therefore, the prevention of gas poisoning and gas leakage has always been a very important item of fire safety publicity. How can we prevent gas poisoning and gas leakage in family life?
1、 What should we pay attention to before using gas?
When using gas, you must pay attention to whether there is odor. When it is confirmed that there is no air leakage, fire and use it, and pay attention to good ventilation.
2、 What should we pay attention to when using gas cylinders?
1. Please pay attention to the inspection period of the cylinder and attach the inspection qualification mark.
2. Please stand the cylinder upright and avoid violent vibration.
3. Place in a well ventilated place away from the sun.
4. Do not put the cylinder upside down for use.
5. Do not place objects on the cylinder to avoid ignition.
3、 How to check whether the gas pipeline leaks?
When it is suspected that there is air leakage in the gas pipe (pipeline) at home, do not use matches or lighters for ignition test. Check whether there is leakage with soap bubbles.
4、 Where is the safest place to install the gas water heater?
It should be installed outdoors in a well ventilated place to avoid the accident of carbon monoxide poisoning.
5、 What is the red flame of gas and fireworks? What are the risks? What should be done?
The gas flame is normally light blue. If it is found to be red, it indicates incomplete combustion. If there is a risk of carbon monoxide poisoning, ask gas professionals to repair and adjust the stove immediately.
6、 How do you know about gas leakage?
1. Smell - household gas is mixed with odorant, which will have self smell when it leaks out.
2. Vision - gas leakage will cause foggy white smoke in the air.
3. Hearing - there will be a 'hissing' sound.
4. Touch -- when the hand is close to the leak, it will feel cool.
7、 How to deal with gas leakage?
1. Turn off the gas switch immediately.
2. Never turn on or off any electrical switch.
3. Gently open all doors and windows and quickly escape the outdoors.
4. Call the alarm for processing.
8、 Can gas kill people?
1. Gas itself is non-toxic, but it has anesthetic and asphyxiating properties, which reduces the ability of biological reaction.
2. When the gas is not used properly, a large amount of carbon monoxide will be produced. Carbon monoxide is easy to combine with heme in the blood, resulting in hypoxia (carbon monoxide poisoning, leading to death).
9、 What should I do if I use gas and lack air to produce carbon monoxide poisoning?
1. Turn off the gas switch.
2. Open doors and windows for ventilation.
3. Provide fresh air for the injured.
4. Untie the shackles and unblock the respiratory tract.
5. Perform artificial respiration or cardiopulmonary abdominal pressure as necessary.
6. Do not turn on or off any power switch before the smell of gas dissipates, so as to avoid sparks and fire.
10、 What are the symptoms of carbon monoxide poisoning?
1. Headache, dizziness, nausea and vomiting. 2. It will have a strong sense of collapse, accelerated breathing and pulse, blurred consciousness, and the body can't move independently. 3. Flushed face, loss of consciousness, respiratory arrest, spasm, resulting in cardiac arrest and death.
11、 What if the gas pipeline is cut off due to the careless construction of sewage pipeline?
If the gas pipeline is accidentally cut off due to the construction of sewage pipeline, please turn off the fire source at home immediately. If the pipeline is on fire, do not put out the fire rashly, delimit a warning line, and call the police as soon as possible. Residents near the pipeline cut off or pedestrians passing by should avoid smoking, or start the steam, locomotive engine and various power switches to avoid explosion or combustion. Personnel should stay away from the scene as far as possible, Before the handling personnel arrive at the scene, please circle the scene with ropes and write slogans such as gas leakage to remind passing personnel and vehicles.
