Low-temperature liquid transport vehicles must also be carefully inspected during transportation.

20 Apr,2021

　　 Cryogenic Liquid Transport Vehicle Vehicles used for the transport of dangerous goods are, in essence, classified as such; therefore, in addition to practicing safe driving, it is crucial to conduct thorough vehicle inspections and to ensure rigorous daily maintenance, upkeep, and safety checks on vehicles transporting hazardous chemicals, so as to prevent vehicles with defects from being put on the road. Particular attention should also be paid to verifying that all required vehicle markings and signage are complete and intact. So, what specific aspects are involved? Please refer to the following analysis provided by CIMC Sanctum, a company specializing in cryogenic liquid transport vehicles.
　　⑴ The medium loaded in the vehicle must be consistent with the medium specified in the tank’s coating and the medium stated on the vehicle’s road transport permit.
　　(2) It is necessary to install conspicuous signage in accordance with the relevant regulations, and reflective markings must be affixed to the vehicle body and rear.
　　(3) Vehicles transporting hazardous chemicals must obtain a vehicle operating permit issued by the road transport administration authority and carry it on board at all times.
　　(4) Escort personnel shall be assigned to each vehicle. Enterprises engaged in the transportation of hazardous goods, as well as the vehicles, drivers, escorts, and loading/unloading personnel, must obtain the corresponding qualifications.
　　(5) After the tank truck has been fully loaded with hazardous liquid cargo, the emergency shut-off valve shall be closed to ensure there is no damage and no leakage.
　　(6) For the transportation of highly toxic chemicals, an application must also be submitted to the county-level public security traffic management department at the destination for a road transport permit for highly toxic chemicals.
　　During transportation, inspections must be intensified to strictly prevent incidents of hazardous chemical leakage. Under normal circumstances, the interior and bottom perimeter of the cargo compartment should be inspected every two hours for any signs of liquid leakage; if leakage is detected, the source must be promptly sealed to prevent environmental contamination.
　　Standard Loaded Goods
　　The cargo in cryogenic liquid transport vehicles must be loaded evenly and balanced, securely fastened as a whole, and each vehicle must carry only one type of cargo. Hazardous chemicals of different risk levels must not be mixed; no empty spaces are allowed between containers. Vehicle exhaust pipes must be fitted with flame arrestors, and for vehicles with metal floors, straw mats or similar materials should also be laid down. After loading hazardous chemicals, the escort personnel must not only carry the delivery manifest at all times but also prepare a detailed written record of the cargo’s name, physical and chemical properties, quantity, disposal methods, and the contact information of the shipping company, so that they can promptly respond to and handle any emergencies that may arise.
　　Select travel time
　　When transporting hazardous chemicals, choose travel times as wisely as possible and avoid lingering on highways at night. During summer, it is advisable to take daytime rest breaks and drive at night to prevent liquid expansion. Under adverse weather conditions such as rain, fog, or ice and snow, as well as during peak holiday travel periods, vehicle dispatch should be minimized whenever feasible.
　　Strictly abide by traffic laws.
　　At present, there is limited room for profit in the transportation sector; therefore, to remain competitive and achieve profitability, transport companies must prioritize safety and never compromise traffic regulations in pursuit of gains.
　　⑴ Drive in the designated lane in accordance with traffic regulations; do not overtake or change lanes arbitrarily, and do not occupy the passing lane for an extended period.
　　(2) Proceed according to the prescribed schedule and route; unauthorized changes to the itinerary are prohibited.
　　(3) Loading shall be carried out in accordance with the approved tonnage; overloading is prohibited, and different hazardous chemicals must not be mixed during transport.
　　(4) Maintain a safe following distance from the vehicle ahead; in adverse weather conditions such as rain, fog, or ice and snow, increase this distance. If a vehicle begins to skid, avoid making sudden steering movements.
　　⑸ Pay attention to getting adequate rest, maintain a clear mind at all times, and avoid driving while fatigued.
　　(6) Stopping and speeding are prohibited on special sections of the expressway, such as tunnels, bridges, and water source protection areas. In addition, vehicles must not pass through tunnels longer than 500 meters.
