When the B certificate expires, you can contact the issuing authority, usually the local construction department or the Construction Committee to organize and implement continuing education.

Certificate B is matched with the builder's certificate, and further education is needed when the certificate expires to prolong the service life of the certificate.

Usually, continuing education is very simple. After studying for 2-3 days, the exam is coming. After passing the examination, you can stamp the certificate and extend the time.

The certificates of safety officers A, B and C are usually in a three-year cycle, that is, continuing education should be completed when the certificates expire after three years.

Continuing education lasts only two days. After passing the study exam, the certificate will be extended for three years, and the cost of continuing education will be about 200-300 yuan. The competent unit of continuing education is the original license issuing agency.
