Industrial gas poisoning, indoor carbon dioxide asphyxia, carbon monoxide poisoning
Industrial gas poisoning, indoor carbon dioxide suffocation, carbon monoxide poisoning, these seemingly distant hazards, in fact, can happen around us every day. With the rapid development of modern society, various industrial activities are also increasing, and the harmful gases produced by them pose a great threat to people's health.
In recent years, due to the improvement of environmental awareness and the strict implementation of relevant regulations and policies, the use of protective equipment in factories and enterprises has become the norm. However, in some special circumstances, such as sudden accidents or equipment failure and other reasons to cause harmful gas leakage, it will still cause serious consequences. For example, a carbon monoxide leak in an electronics factory recently came to light: dozens of employees were sent to the hospital for treatment, and unfortunately, two people died. It can be seen that even in places with perfect security measures, we should not relax our vigilance.
In addition to factories and businesses, indoor Spaces are also potentially dangerous. With the increasing density of urban construction, poor ventilation often occurs in public places or housing districts. Especially in high summer temperatures, people close their Windows to save energy, and indoor carbon dioxide concentrations rise rapidly. If people are exposed to such an environment for a long time, they will experience symptoms such as dizziness, weakness, breathing difficulties, and even suffocation in severe cases.
Carbon monoxide is also a potential killer for homes. Because carbon monoxide is colorless and odorless, it is easy to overlook when using gas stoves or heating devices. If the room is not well ventilated or the equipment fails, carbon monoxide poisoning is possible. According to statistics, there are hundreds of carbon monoxide poisoning incidents every year because of household appliances, and most of them occur during sleep.
In the face of these hidden dangers, how should we prevent them in our daily life? First of all, we should do a good job of safety awareness education, so that everyone knows what kind of circumstances need to take protective measures; Secondly, we should strengthen the formulation and implementation of relevant regulations and standards; Finally, the awareness of self-protection is improved: for example, the living environment should be kept ventilated to avoid long-term exposure to harmful gases; When using gas equipment, check the safety performance regularly, etc.
Industrial gas poisoning, indoor carbon dioxide asphyxiation, carbon monoxide poisoning, these dangers are not terrible, as long as we take preventive measures and improve self-protection awareness, we can effectively avoid tragedy.

At around 19:40 on June 12, a hydrogen sulfide gas leak occurred in Kunming Anning Qitian Fertilizer Co., LTD., resulting in 6 deaths and 28 people receiving treatment and staying in hospital for observation. The father of one of the victims, mentally and emotionally devastated, committed suicide by taking poison.
The direct cause of the accident is the deficiency of process design, the absence of display control instruments and safety facilities for sodium sulfide solution flow, and the corresponding operating procedures; At the same time, the top of the phosphoric acid tank is not closed and is not equipped with a hydrogen sulfide tail gas absorption system, which cannot remove excess hydrogen sulfide gas, resulting in the gas entering the work site.
The root cause of the accident is weak production safety supervision and hidden dangers have not been eliminated. The enterprise did not go through the strict "three simultaneous" review when it built the factory, in order to improve economic benefits in the production process, it carried out product tests without consent, installed and reformed equipment, and used 46% of industrial phosphoric acid, sodium sulfide and water as raw materials to reaction and produce dearsenic acid, and the final product was calcium hydrogen phosphate. In the course of the product test that night, there was no scientific safety equipment to guarantee the site was disorganized, resulting in the escape of hydrogen sulfide, causing heavy casualties.
