Transportation and protective measures of dangerous goods

dangerous goods transported by automobile can be divided into eight kinds: explosives, compressed gases and liquefied gases, flammable solids, spontaneous combustion substances and flammable substances when wet, oxidants and organic peroxides, poisons and infectious substances, radioactive substances and corrosive substances, which are excellent thermal insulation materials

the transportation of dangerous goods must have transportation equipment and loading and unloading equipment to ensure safety, and have operation management personnel and drivers who are familiar with the performance of dangerous goods to ensure the safety of dangerous goods transportation

drivers engaged in the transportation of dangerous goods must be serious, responsible, skilled and professional drivers who understand the relevant knowledge of the transportation of dangerous goods. Non professional drivers are not allowed to transport dangerous goods. The transportation of dangerous goods also has certain requirements for vehicles

basic requirements for motor vehicles: 1. The cargo compartment should be made of wooden bottom plate. Considering that the vast majority of dangerous goods are inflammable and explosive, the wooden base plate can avoid sparks, which is relatively safe. At the same time, it is required that the surrounding fence must be firm. When transporting inflammables and explosives with iron bottom carriage, corresponding cushion protection measures shall be taken. The carriage must be kept clean and dry, and there must be no residue on it. 2. The exhaust pipe of motor vehicles must be equipped with heat insulation and spark extinguishing devices, and the circuit system should be equipped with devices that are easy to cut off the power supply. 3. According to the nature of the loaded dangerous goods, corresponding fire-fighting equipment and strapping, waterproof, anti loss and other equipment shall be equipped

basic requirements for tank car the successful test of the first VCC pilot plant in China: 1. The material of the tank (tank) carrying dangerous goods must be compatible with the nature of the goods loaded. Generally, carbon steel tanker can be used for dangerous goods such as concentrated sulfuric acid and alkaline liquid; Aluminum tank for nitric acid application; Put a liner seal at the slot cover to prevent leakage. Hydrochloric acid, hypochlorous acid, waste nitric acid, etc. should be made of FRP and stainless steel. 2. It shall be reliable and strong enough, and shall be equipped with double gates, pressure relief valves, wave boards, sunshades, pressure gauges, liquid level meters, electrostatic conductivity and other corresponding safety devices according to the needs of different goods, so as to ensure that the loaded goods do not leak. The above devices should adopt corresponding devices according to the nature of the dangerous goods loaded, such as flammable liquid gasoline, benzene, etc. during transportation, the liquid will continuously move and generate static electricity. Therefore, a grounding rubber tow Belt should be installed at the rear of the vehicle to derive static electricity; For example, when transporting dangerous goods that are afraid of the sun and high temperature in summer, it is necessary to put a shed on the tank (tank) or cover it with corresponding sunshades. 3. The equipment and use of LPG tanker must meet the requirements of the safety management of LPG tanker issued by the former State Administration of labor. 4. Vehicles carrying containers, large gas cylinders (500kg 2000kg liquid chlorine, liquid ammonia and other steel cylinders) and movable tanks (tanks) temporarily lifted up and down must be equipped with effective solid equipment and corresponding wooden plugs

basic requirements for special transport vehicles and equipment for transporting radioisotopes: 1. It should comply with the relevant regulations of health and epidemic prevention, public security and other departments. 2. Vehicles, equipment, handling tools and protective articles shall be regularly inspected for radioactive pollution. When the pollution exceeds the allowable standard, they shall not be used anymore. 3. If the radioactive intensity of pollution exceeds the specified amount, it must be cleaned and disinfected before continuing to use

basic requirements for loading and unloading machinery: 1. All kinds of loading and unloading machinery and workers should have sufficient safety factor. Generally, the design requirements exceed 1/3 of the load capacity, such as 5T crane and crane, which should be able to reach a lifting capacity of 6t~7t. 2. Machinery carrying inflammable and explosive dangerous goods must have explosion-proof devices to eliminate sparks. It is forbidden to use tools that are prone to friction and spark, and special explosion-proof tools made of aluminum copper alloy are used. 3. The clamping tools used shall not possess pollutants that conflict with the nature of the loaded goods

in the transportation process of dangerous goods that avoid the impact during hanging and swinging and the damage it may cause, if there is leakage, measures should be taken in time according to the protective measures. 1. Explosives: quickly transfer to a safe place to repair or replace the packaging, wet the leaked items with water in time, sprinkle some soft objects such as sawdust or cotton wool, gently collect them, and notify the fire department to deal with them. 2. Compressed gas or liquid gas; Quickly open the car door and warehouse door and move to a ventilated place. When liquid ammonia leaks, it can be immersed in water. Other highly toxic gases should be immersed in lime water. Rescuers should wear gas masks, and other personnel should stand upwind. 3. Spontaneous combustion products or products that burn in water: after yellow phosphorus is scattered, it must be quickly immersed in water, and metal sodium, potassium, etc. must be immersed in an iron bucket containing kerosene and anhydrous liquid paraffin. 4. Inflammables: timely put the leakage part upward. Cover the spilled materials with dry yellow sand and dry soil and clean them up. In case of expansion of high-temperature vessels, water shall be used for cooling. 5. Toxic substances: quickly cover them with sand and soil, evacuate personnel, and timely ask the health and epidemic prevention department to help deal with them. 6. Corrosive products: cover them with sand and soil in time, and wash them with clean water after cleaning. 7. Radioactive materials: keep away from radioactive sources quickly, protect the site, and ask the health and epidemic prevention department for guidance
