On the evening of December 22, an incident occurred in a restaurant in Baibi Town, Anyang County, Henan ProvinceHot potPoisoning tragedy, which killed 3 people and injured 3 others. According to Mr. Wang, a local villager, at about 11 o'clock that night, four villagers and two other villagers ate charcoal at a local restaurantHot potAn unfortunate event occurred. One of them felt unwell while eating at the restaurant and died after being taken home by his wifeAnother person died in a restaurant, and another died on the way to the hospital. According to the confirmation of the villagers and merchants concerned, a total of three people were killed and three injured in the accident.
According to preliminary understanding, the cause of this incident is:Carbon monoxidePoisoning. The local ** staff said that after the accident, the relevant departments have intervened in the investigation and dealt with it. Simulation experiments show that in the cold environment of winter, indoor charcoal is eatenHot pot, fires and other activities are easy to causeCarbon monoxidePoisoning. In recent years, it has become popular "around the hearth."Boiled tea"It also existsCarbon monoxiderisk of poisoning, so it is necessary to be vigilant.
Carbon monoxideIt is a colorless, odorless and non-irritating toxic gas that poses a serious threat to human health. According to research,Carbon monoxideAt a concentration of 50 ppm, it has reached the maximum level that an adult can tolerate, while at 200 ppm, the human body will experience mild poisoning symptoms such as headache, dizziness, and nausea. WhenCarbon monoxideAt concentrations above 400 ppm, a person's life may be in danger.
During the winter months, many people are used to burning indoorsCoalheating,Boiled teaRoasting fire, due to poor air circulation, is easy to causeCarbon monoxidePoisoning. When a person finds that his face is red and dizzy when he is roasting, he is likely to be in a state of slight poisoning. At this time, you should immediately open the doors and windows and go to a ventilated place to breathe fresh air.
1. Keep the indoor ventilation good, and often open the window for ventilation to ensure air circulation
2. Try to avoid burning in a confined spaceCoalBoiled teaand fires, or keeping doors and windows open during these activities;
3. When using gas equipment, it is necessary to ensure the normal use of the equipment, and carry out regular safety inspection and maintenance
4. In the cold winter, try to choose a safe and reliable heating method to avoid the use of unknown fire sourcesCarbon monoxideRisk of poisoning.
In recent years, "around the hearthBoiled teaIt became a popular way to party in winter. Friends sit around the fire and enjoy steaming tea and food, warm and pleasant. However, if at home for a long time with the doors and windows closed for a long time to carry out "around the hearth."Boiled tea", will lead toCarbon monoxideand then cause poisoning accidents.
In order to arouse everyone's interest in the "hearth."Boiled teaMediumCarbon monoxideAttention to the risk of poisoning, NanningFirefightingFor the interior "around the hearth."Boiled tea"Scenario simulation experiments were conducted. In experiments,FirefightingThe company uses a composite gas detector to measureCarbon monoxideconcentration. At the beginning, indoorsCarbon monoxideThe concentration is 148ppm, but with the burning of the stove and the boiling of the tea, indoorsCarbon monoxideThe concentration rose rapidly and eventually reached 142 ppm.
Such high concentrations are already very easy to causeCarbon monoxidePoisoning. Therefore, we should be aware of the "hearth."Boiled teaIn particular, it is necessary to strengthen ventilation and avoid indoorsCarbon monoxideThe concentration is too high, causing potential safety hazards.
In summary,Carbon monoxidePoisoning is a common but easily overlooked safety risk. In the cold environment of winter, we should be especially vigilant about eating indoorsHot pot, fire heating and other activitiesCarbon monoxideRisk of poisoning. By maintaining good ventilation, proper use of gas appliances, and paying attention to the "hearth."Boiled tea".Carbon monoxideexclusion, we can effectively preventCarbon monoxidePoisoning accidents occur and contribute to the safety of families and communities. Let us call on everyone to enhance safety awareness, pay attention to prevention, and protect the safety of life!
