Leakage Accident Characteristics
Strong sudden, poison leakage
Leakage accident generally suddenly occur, often unexpected Time, place, this suddenness is related to the particularity of hazardous products and its production process.
The range of harm is wide, and there are many damage pathways. After the accident occurs, the poison will cause large in a variety of forms to the air, water source, surface and objects. Area contamination. There are many hurts, and the toxic substances form the cloud group spread around, especially the direction of the lower wind, causing a wide range of pollution, and the damage effect is enhanced.
Inspection is not easy, rescue difficulty is large
Dangerous videos, what kind of substance that is difficult to detect accurate investigation, while leaking and explosion A small environment that may form "high temperature, high pressure, hypoxia, and toxic" gives a lot of difficulty, and higher requirements for personal protective equipment and equipment.
Pollution environment, toxic and harmful substances after washing difficult accidents can be contaminated with air and object surfaces, and even toxic liquids can penetrate deep pollution, once contaminated, to completely wash the pollution area It is very difficult. On November 13, 2005, an explosion occurred between the Jijin double-benzene car, which not only triggered social turmoil, but also caused serious pollution in Songhua River, which has been affected by Russia.
The social involvement, the political impact is the serious hazard caused by the control and elimination of serious dangerous goods, the rescue action will be launched around the cut (control) accident source, alert, evacuation and other links. These actions are bound to cause local or residents' life imbalance, and even chaos in social order, even have a negative impact on the international.
Foreign treatment method
Applicable to fuel overflow, spraying Baisuofu can be used to eliminate fire and explosion. Sprayed onto the spray in the form of a dilution solution, it can compress and encapsulate contact with hydrocarbon molecules, so that the A-grade Class B (hydrocarbon) flame can be extinguished. Since the hydrocarbon molecule is sealed, the lower limit of the explosion will decrease immediately, and can be changed to 0. It is also possible to facilitate road cleaning, remove oil stains that can form driving hazards. The existed steam emissions can be reduced on the site, and the hazards caused by workers or a more annoying odor is produced in the adjacent region. The gathering of Baico is sprayed on site or stored contaminated materials, which can greatly reduce the vapor pressure by encapsulating hydrocarbon molecules. Reduce the scent or potential steam to 0 to form a barrier to store steam in the soil, so that the construction personnel continue cleaning in a safe state.
