There are two types. One is the four-member certificate of blaster: blaster, safety officer, storekeeper and escort, which is assessed and issued by the public security organs of prefecture-level cities with districts and counties.

The second is the certificate of blasting technician, which is divided into four levels: primary, intermediate and advanced, and intermediate and advanced are divided into ABCD. The primary certificate is issued by the provincial public security department, and the intermediate and advanced certificate is issued by the Ministry of Public Security.

Public security organs at all levels will hold training courses from time to time for training and assessment, then pay attention to the notice of public security organs or provincial blasting association, and then sign up for training and assessment according to their own conditions.

If it is a blasting construction procedure, it should be handled directly in the public security organ, and you can consult the local public security organ.
