The key to handling leakage is to find out the leakage point in time and control the hazard source.Hazard source controlIt can be carried out from two major aspects, namely, process emergency control and engineering emergency control.The second is to deal with it in time, and the third is to check the cause of leakage afterwards.

Strong suddenness and large amount of poison leakage
Leakage accidents usually happen suddenly, often at unexpected time and place, which is related to the particularity of hazardous chemical products and their production process.
Wide range of hazards and many ways of injury
After the accident, poisons will spread to the air, water sources, surface and objects in various forms, resulting in large-scale pollution.There are many ways of damage. Poisonous substances form clouds and spread around, especially downwind, causing large-scale pollution and increasing damage effect.
It is difficult to detect and rescue
There are many kinds of dangerous products, so it is difficult to accurately detect the substances that cause them. At the same time, the leakage and explosion may form a small environment of "high temperature, high pressure, oxygen deficiency, and toxicity", which will bring great difficulties to rescue. There are high requirements for personal protective equipment and equipment.
Pollution of the environment and difficulty in cleaning up After an accident, toxic and harmful substances can pollute the air and the surface of objects, and even toxic liquids can penetrate the surface to cause deep pollution. Once the pollution is formed, it is very difficult to thoroughly clean up the polluted area.On November 13, 2005, an explosion accident occurred in the Jihua double benzene workshop, which not only caused social unrest, but also led to serious pollution of the Songhua River, affecting Russia.
With a wide range of social and political influences, the serious hazards caused by major hazardous material accidents can be controlled and eliminated. The rescue operation is bound to focus on cutting off (controlling) the source of accidents, warning, evacuation and other links.These actions are bound to cause imbalance in the lives of local areas or residents, even chaos in social order, and even have a negative impact on the international community.

Leakage emergency treatment
When applied to fuel spillage, Pentethoff can be used to eliminate fire and explosion hazards.Spray it on the overflow in the form of diluted solution, which can compress and encapsulate the hydrocarbon molecules in contact, so that Class A and Class B (hydrocarbon) flames can be extinguished.Since hydrocarbon molecules are sealed, the lower explosion limit will immediately drop to 0.It can also facilitate road cleaning and remove oil stains that can cause driving hazards.On the construction site, the existing steam emission can be reduced, which may cause harm to workers or produce unpleasant odor in the adjacent area.The steam pressure can be greatly reduced by encapsulating hydrocarbon molecules by spraying BSF on the site or in the gathering area where contaminated materials are stored.Reduce or reduce the odor or potentially harmful vapor to 0, forming a barrier that can preserve the vapor in the soil, so that the construction personnel can continue cleaning in a safe state.
