Hazardous chemicals need to be transported by means of transportation from production to storage and use. Due to its own danger, dangerous chemicals may cause serious disasters such as burning, explosion, corrosion and poisoning during transportation, endangering public safety and the safety of people's lives and property, leading to environmental pollution. Emergency treatment of leakage in the transportation of dangerous chemicals can reduce losses, and relevant emergency disposal can start from the following aspects. First, as soon as possible, alarm, organize personnel to rescue Dangerous chemicals leak due to traffic accidents or other reasons. Drivers, escorts or people around them should try to report to the police as soon as possible, report to the local public security fire department or local public security organs, take emergency measures if possible, or inform the surrounding situation about the dangerous situation. The masses try to reduce losses. A few years ago, a large truck carrying 9 tons of liquid bromine was routed through the 107 National Road, Hesheng Bridge, Xianning City, Hubei Province. Due to the driver's fatigue driving, the truck was out of control and slammed into the isolation belt at the center of the National Highway. The body immediately tilted over. Due to the violent impact, the glass bottles and porcelain bottles containing bromine on the vehicle are damaged, and the liquid bromine leaks outward. Bromine is chemically active and can react with many substances. It is a dark red fuming liquid at normal temperature. Its steam is reddish brown, irritating and odorous, and it is strongly corrosive and toxic. Human tissue is exposed to bromine, and human cells will Damaged to form a serious chemical burn. Bromine is also a strong oxidant. It can cause burning when it reacts with organic substances such as wood, cloth and paper. It has strong corrosive effect on metal products and house structures, causing damage. The driver who knew the harm of bromine broke open the glass of the cab and screamed to the surrounding and repeatedly shouted: "The drug leaked, please go near the crowd quickly..." At that time, a masse went to the police station to report that he was on duty. The police immediately reported to the relevant departments. The Xianning District Fire Brigade and the Xianning City Traffic Police Brigade organized personnel to quickly arrive at the scene of the accident for rescue, which made this serious chemical spill accident quickly controlled. Second, put an end to the fire source to prevent explosion If the dangerous chemicals leaking are flammable and explosive materials, all fire sources should be eliminated in the field and around. All electrical equipment should be turned off, all vehicles must be stopped, and communication tools such as mobile phones must be turned off to prevent sparks from igniting flammable gases, combustible liquids, or combustible dust. If the tank, container, and tanker are damaged, try to plug the loophole as soon as possible and cut off the source of the accident. Plugging holes can be blocked with soft rubber, clay, plugs, cotton yarn, quilts, soap and other materials. Third, take appropriate disinfection measures If the dangerous chemicals transported are corrosive and toxic, in the process of handling the accident, we must take active and prudent measures to minimize the damage to corrosive and poisonous items. In the case of chlorine leakage, a large amount of water can be used to spray the contaminated area. Soda powder (sodium carbonate) can be added to the water, and soda can be sprayed on the ground to reduce the concentration of chlorine in the air to reduce the hazard; Cylinders, immersed in excess lime milk water. If the alkaline material such as ammonia gas leaks, it can be diluted and diluted with a large amount of spray water. The leaked container can be immersed in the dilute hydrochloric acid solution according to the actual situation. If it is a kind of corrosive substance such as sulfuric acid, it can not be diluted with water, and it can be used for covering and absorption of sand and dry soil. If the liquid bromine leak can be covered with ammonium bicarbonate, the bromine and ammonium bicarbonate will react to form ammonium bromide, which is much less toxic than liquid bromine; it can also be covered with lime to form calcium hypobromite and bromination. Calcium greatly reduces toxic components. If the sodium cyanide leaks, it can be disinfected with calcium hypochlorite. If the arsenic leaks, it can be disinfected with lime. On-site rescue personnel should also wear anti-drug clothing, gas masks, anti-virus gloves, anti-virus boots, and prevent contact with the respiratory tract and skin into the human body according to the characteristics of toxic substances. Wear protective gear to reduce exposure to exposed parts of the body and reduce damage. In addition, if the dangerous chemicals leaked out are liquid chlorine, liquid ammonia, liquefied petroleum gas, etc., in addition to preventing combustion, explosion, and poisoning, it is necessary to prevent frostbite. Chlorine, ammonia, and petroleum gas are gases at normal temperature. In order to facilitate storage, transportation, and use, the industry adopts measures of pressurization and temperature reduction to make it liquid, and store it in cylinders, storage tanks, tank trucks, if transit occurs. Accident, the container valve is damaged, or the container is broken, resulting in the leakage of liquefied gas. As the pressure is reduced, the leaked liquid can be quickly converted into a gas. This process needs to absorb a large amount of heat, so that the temperature of the surrounding environment is rapidly lowered. Rescue personnel at the scene of the accident should pay attention to prevent frostbite. Fourth, strengthen the monitoring of on-site leakage During the disposal of hazardous chemicals, special attention should also be paid to monitoring the leakage of on-site items. In particular, the leakage of highly toxic or flammable and explosive chemicals should be strengthened. Relevant departments should organize professional testing technicians and inspection equipment to be on hand to conduct rapid testing, determine the nature of the leaked chemical materials, the degree of hazard, and the scope of the hazard. Sometimes it is necessary to check to find out which chemical substance is leaking. This work is very important, and it is necessary to continuously monitor and measure, report the test results to relevant departments, and provide a reliable data basis for safe disposal decisions.
