In 2021，the effect of the special rectification of work safety will gradually appear，which is mainly reflected in the fact that the frequent occurrence of major events in the hazardous chemical field has been curbed，and the work safety situation continues to improve. In general，China’s reform in the field of work safety has shifted from “structural adjustment” to ‘precise fine-tuning’. The future work safety is more about the persistence，continuation and implementation of the preliminary reform work. In view of the new situation，the work safety in the next step also needs to be adjusted and improved in a timely manner.
