As for transportation, make sure that the packaging is complete and sealed before transportation. Poor packaging or leakage of substances will not only damage the goods, but also endanger the transportation environment and personnel safety. During transportation, the speed should be stable, and severe vibrations and bumps such as sudden braking and sharp turns should be avoided to prevent packaging damage.
Transport vehicles must also meet safety standards and be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. Once there is a leak on the way, it can be dealt with in time. Escort personnel need to be professionally trained, familiar with the characteristics of the substance and emergency treatment methods, pay close attention to the status of the goods during transportation, and deal with any abnormalities immediately.
