Analysis and prevention of hidden dangers of refrigerated truck accidents(2)

During the unloading process, the cargo compartment was opened for too long. When the refrigerated truck is unloading, it is necessary to keep the container door open, but if the unloading speed is too slow or the door is not closed at any time, the temperature of the compartment cannot be maintained, which will undoubtedly increase the burden on the refrigeration equipment and consume energy. More serious, the unstable temperature difference between the inside and outside of the cargo compartment may also cause damage or explosion of the cargo compartment.

The above-mentioned causes of accidents require drivers and loading and unloading personnel to take adequate safety measures in all aspects of refrigerated vehicles to ensure safety.

Before loading, check whether the parameters such as temperature, relative humidity, and fresh air exchange rate are set correctly, and turn off the refrigeration system at the same time. Pre-cool or preheat the temperature of the carriage to the temperature required for cargo transportation for about 1.5 hours.

When loading cargo, the cargo in the carriage should be stacked firmly, the height of the stack should not exceed the lower edge of the air outlet of the refrigeration unit, and it should not be overloaded. Sufficient ventilation space should be left around the cargo to ensure air circulation.

During the driving, the driver should always pay attention to the working condition of the driving temperature recorder and whether the temperature in the cabin is abnormal. If any abnormality is found, stop using it immediately and guarantee it. At the same time, we should strictly abide by the traffic rules, prohibit speeding, drunk driving, and fatigue driving to ensure the safety of ourselves and the cargo.

When arriving at the destination, the driver should wait for the driver to park at the best position and turn off the engine before unloading. Before unloading, the refrigeration unit must be turned off to prevent the cold air from being blown out and the hot air to be quickly sucked in when the door of the car is opened without shutting down, causing the temperature of the car to rise rapidly.

During unloading, every effort should be made to keep the compartment temperature basically unchanged, which requires porters to accelerate the unloading speed or carry out cargo separation. When unloading, pay attention to closing the door of the carriage at any time and do not be careless.

In order to reduce safety accidents, the maintenance of refrigerated trucks is essential. Generally speaking, the chassis engine is maintained and maintained according to the mileage, while the refrigeration unit is maintained and maintained according to the engine working hours, and the cycle is usually 500-700 hours. In addition, the driver should pay full attention to small structures such as filter elements, belts, and electrical connectors, check them regularly, and replace defective parts in time. Only by maintaining the car well can driving safety be ensured and accidents can be reduced.
