China stipulates that the duration of safety training for new employees in production and operation enterprises should not be less than 24 hours, and the duration of safety training for new employees in some high-risk industries such as hazardous chemicals should not be less than 72 hours.
Three-level safety training means that new employees of enterprises must undergo company-level safety training, department-level safety training and class and group-level safety training before taking up their posts. Mainly to cultivate employees' awareness of safe production, eliminate unsafe factors in the production process as much as possible, and effectively prevent the occurrence of safety accidents.
