Do you still need to study when Guangzhou Dangerous Transport Certificate expires? What is the content of the study?

To learn, give priority to road safety education.

The representative whose certificate of hazardous chemicals has expired is not qualified for this job. Before the replacement, he needs to continue to complete his education and study, and must apply to the relevant departments for review and re-obtain the corresponding qualifications. I mainly study laws and regulations, safety knowledge and related case warnings.
