When the occupational health work is centralized in the health department, the training and certification shall be organized by the health department. Certificates are divided into provincial and national levels. The provincial evaluation certificate is organized by the Provincial Occupational Prevention Institute (or CDC) and issued after passing the examination; National training, certified by the National Center for Disease Control and Prevention. Training is conducted irregularly. Generally, the unit where you work will organize personnel to participate in training. If there is a training organizer, it will be notified by the unit, and it is not necessary to pay for the training.
At present, the occupational health work is under the centralized control of the Security Bureau, and the occupational health work has not been completely handed over. I wonder if the health department will organize training? Anyway, don't worry. The unit will inform you when there is training.
