technical field

Background technique

With the rapid development of my country's economy, the consumption of flammable, explosive, toxic and harmful liquid substances has increased significantly. According to statistics, more than 95% of hazardous chemicals in my country are involved in off-site transportation. The daily transportation volume of hazardous chemicals exceeds 1 million tons, and the annual transportation volume exceeds 400 million tons. According to incomplete statistics, between August 2005 and July 2008, there were 1,565 hazardous chemical accidents in my country, resulting in a total of 945 deaths and 8,765 injuries. So many hazardous chemical accidents occurred in just three years, seriously endangering the lives and property safety of the people.

These flammable, explosive, toxic and hazardous substances often leak accidentally during production, storage and transportation. The occurrence of accidents will not only lead to huge economic losses, but also may lead to catastrophic consequences, resulting in disastrous consequences of human and financial losses, especially the irreversible damage to the ecological environment will be irreversible. Once there is a sudden leakage accident of the automobile tanker, it is very easy to form a flammable and explosive mixture, and then it can cause combustion, explosion and casualty accidents, which seriously threaten the safety of people's lives and property and environmental protection. The scene of the accident is generally on the main road of traffic. Once the disposal is unsuccessful, the traffic will be paralyzed.

Therefore, it is required that fire rescue personnel must be able to quickly and accurately judge the type of accident and formulate corresponding rescue plans, which puts forward higher requirements for rescue personnel training. Therefore, carrying out accidental leakage and emergency plugging test and simulation training research is of great significance for the formulation of accident emergency plans and emergency rescue for major hazards. However, the fire training device in the prior art cannot truly restore the accident scene.
