A tragic tragedy occurred in Yichun City, Jiangxi Province, the young couple was gas poisoned while bathing, both died, and what was even more tragic was that the couple left 8 children waiting to be fed. You read that right, not an 8-year-old, but 8! 8 children, in today's fertility rate continues to decline, the younger generation is not willing to have children in the era, there are people who can have 8 children, it is really courageous, however, people die Pepsi, poor 8 children, it is said that the largest is only 10 years old, the youngest is only 9 months, to say that now is really a good society, the final result is the government bottom, thank the country, thank the government!
However, then again, every autumn and winter, after the weather turns cold, there will always be reports of accidents that killed due to carbon monoxide poisoning caused by bathing, every year, every year, why such tragedies occur repeatedly, things related to life safety, take a bath to confess, it is inevitable that it is a little too wronged, how to be poisoned when bathing, why is the poisoning often so serious?
At present, the commonly used water heaters in the home are divided into two kinds of gas water heaters and electric water heaters, the biggest feature of gas water heaters is that the heating speed is fast, and the gas water heater is very small, some brands or styles may only be one-tenth of the size of the electric water heater, which is very saving indoor space, and more importantly, the gas water heater should be economical and practical, the cost, The use cost of a gas water heater per kilowatt is only 0.186 yuan (natural gas is calculated at 2 yuan per cubic meter); the heat of 1 kilowatt is 1KW, and the cost of use per kilowatt is 0.51 yuan (the electricity fee is calculated according to 0.5 yuan per kilowatt). It can be seen that gas water heaters cost nearly two-thirds less than electric water heaters.
Therefore, the gas water heaters currently on the market are basically fast water heaters. This kind of water heater usually opens the switch to produce hot water no matter what time, basically without waiting. The electric water heater is much slower than the heating speed, generally each heating requires a certain waiting time, that is, each bath needs to open the water heater switch in advance, and can be used after the water temperature reaches.
Of course, electric water heaters are not useless, hot gas water heaters must produce exhaust gas after natural gas combustion, in addition to carbon dioxide, there is carbon monoxide in the exhaust gas. In the case of normal use and good ventilation, carbon monoxide is very small, but if the doors and windows are closed when used, poor ventilation, carbon monoxide will increase, and poisoning accidents will occur in severe cases. However, electric water heaters are relatively safer and healthier, not affected by the climate, and do not have any environmental impact on the indoor environment when used.
Since the gas water heater is popular and can be loved by people, natural safety factors must also be taken into account, the main component of gas is methane, methane combustion equation: complete combustion: CH4 + 2O2 = CO2 + 2H2O (reaction condition is ignited) methane + oxygen → carbon dioxide + water vapor; incomplete combustion: 2CH4 + 3O2 = 2CO + 4H2O, from the equation of methane combustion to understand the source of carbon monoxide, without sufficient combustion, a large amount of carbon monoxide is produced.
As mentioned earlier, the gas water heater must be considering safety factors, so the more common gas water heaters are mainly strong exhaust water heaters and balanced water heaters, strong exhaust water heaters built-in exhaust fans to discharge exhaust gas, but take the natural intake, natural intake consumption is still the oxygen of the bathroom, so the time will still be lack of oxygen, but due to the forced discharge of exhaust gases to the outdoors, carbon monoxide poisoning is greatly reduced; balanced water heaters communicate with the outside world through double exhaust pipes, and two exhaust fans are built in, One is responsible for inhaling the air for combustion from the outside, and the other is responsible for discharging the exhaust gases outdoors, which is the safest and ideal, and there will be neither lack of oxygen nor poisoning.
In-line water heater, it is simple and rough, natural suction, natural exhaust, suction is of course the oxygen of the bathroom, exhaust gas synchronous emissions to the room, resulting in a large reduction in oxygen, and poison gas increase, very easy to cause hypoxia and poisoning, the state has long banned the production of this water heater, so do not be greedy to buy, at the same time the early of this water heater should also be replaced in time into a safe forced or balanced water heater, no wonder netizens commented that less children, save money for a safe water heater, but also not to die, Leaving 8 children in vain is extremely pitiful.
Carbon monoxide is a colorless, odorless, non-irritating gas, so it is difficult to find its presence, and the solubility in water is very low, not easy to dissolve in water. After carbon monoxide enters the human body, it will bind to hemoglobin in the blood to produce carboxyhemoglobin, which in turn makes hemoglobin unable to bind to oxygen, causing hypoxia in body tissues, resulting in suffocation and death.
In general, mild intoxication manifests as headache, dizziness, blurred vision, tinnitus, nausea, vomiting, malaise, tachycardia, and transient fainting. At this time, if it is not controlled, the above symptoms will be aggravated, and there will be a heart rate acceleration, arrhythmia, at this time, although you are conscious, but you are unable to control your movements, after which you will quickly enter a coma, and finally die due to respiratory paralysis.
Carbon monoxide poisoning such as boiled frogs in warm water, at first it is not fatal, but it will not make you realize that you are poisoned, and once you feel uncomfortable, suspect that you are poisoned, it is too late at the moment, although the consciousness knows that it is poisoned, but it is unable to control their own body, can only wait for death, acute carbon monoxide poisoning is the highest number of acute occupational poisoning in China. Carbon monoxide is also the poison that causes the largest number of deaths in many countries that cause accidental daily poisoning, which shows the terrible nature of carbon monoxide poisoning.
As mentioned earlier, it is almost impossible to save yourself after poisoning, then prevent it in advance, first do not use a in-line water heater, secondly, pay attention to ventilation in the bath, the bath time should not be too long; and once the family carbon monoxide poisoning is found, the window should be opened for ventilation immediately, the poisoned person should be moved to the ventilation place, and when it is serious, artificial respiration, cardiopulmonary resuscitation can be done, and if necessary, dial 120.
Every year there are many incidents of carbon monoxide poisoning, everyone understands, just like a ridiculous sentence: after the incident, everyone is Zhuge Liang, but beforehand it is like a pig, do not be careless, do not take chances, I hope this incident is the last carbon monoxide poisoning this year, there is no such tragedy again, poor 8 children have no father and no mother.
