The Construction Department or Construction Committee of Chengde will organize the implementation of continuing education. After the expiration of the safety officer B certificate, continuing education should be carried out immediately, otherwise it will affect the company's bidding and annual review. The safety officer B certificate is matched with the builder's certificate. The certificate is valid for two years, and continuing education is required after the certificate expires. The purpose is to extend the service life of the certificate. Continuing education is simple. After studying for 2-3 days, the exam is coming. After passing the examination, you can stamp the examination seal on the certificate to extend the time. If the certificate expires, you can contact the issuing authority. Therefore, Chengde will be organized and implemented by Chengde Construction Department or Construction Committee in 2022.
