Transportation of hazardous chemicals: networked joint control to ensure safety
"‘Zhejiang H01247 is carrying carbon tetrachloride and has entered Ningbo City.’ At 7:00 a.m. on April 24, Mao Xihui, a monitor at the satellite positioning system (GNSS) of the market configuration department of Juhua Group Automobile Transportation Co., Ltd., pointed out a red arrow on the computer screen. The image displayed dozens of vehicles transporting hazardous chemicals, clearly visible on the company’s monitoring system.
With the rapid growth of road freight in China, incidents involving hazardous chemical transport have increased. Lack of oversight over these vehicles has become a major cause of accidents. Previously, vehicle management systems were fragmented across provinces, with each region operating its own independent monitoring platform. This made it difficult to track external vehicles and led to poor information sharing among different regulatory departments such as the Ministry of Transport, the Ministry of Public Security, and the State Administration of Work Safety.
To address these issues, the national key operation vehicle networking control system was launched in 2010. In 2011, several ministries jointly issued a notice requiring all hazardous chemical transport vehicles to be equipped with GNSS terminals that meet specific technical standards and connect to approved monitoring platforms. Enterprises are now responsible for ensuring accurate data transmission and real-time tracking of their vehicles.
Currently, 175,000 hazardous chemical transport vehicles are connected to the national network. Through this system, operators can track the location of vehicles in real time. In case of an accident, they can quickly identify the owner, the type of goods, and the carrier involved. Local authorities can also access this data and coordinate with traffic police for better supervision.
In recent years, many cities have started to implement GNSS on hazardous chemical transport vehicles. For example, Shanghai mandated the use of GNSS in 2009, while Jiangsu and Ningbo have achieved full coverage. Experts predict that the next step is upgrading GNSS terminals to 3G technology, allowing real-time video streaming, driver communication, and more detailed monitoring of driving conditions.
Juhua Group has upgraded its GNSS and 3G monitoring systems, ensuring 24/7 tracking of all its 215 vehicles. Xin’an Chemical Company has also strengthened its use of real-time GNSS monitoring to prevent speeding and unsafe driving behaviors. Meanwhile, Ningbo Zhenhai Jinyang Chemical Logistics has installed video surveillance terminals combined with GNSS, significantly improving the safety of chemical transportation.
Under strict regulation from the Ministry of Transport, awareness of transportation safety among chemical companies is steadily improving."
What kind of valve does a washing machine use? The water inlet valve on your washing machine is the part that connects the two water hoses to the machine, and it controls the flow of both hot and cold water. A problem with the valve can cause the washer to not fill properly or not fill at all.
