Therefore, the “Steam Boiler Safety Technology Supervisory Regulations” (LaoRenGuo 1987 No.4) issued by the former Ministry of Labor and Personnel cannot meet current requirements for the supervisory of safety and technology. Therefore, we have revised the original regulations thoroughly on the basis of making extensive investigations and soliciting experts opinions. Now, the newly revised “Steam Boiler Safety Technology Supervisory Regulation” is issued to you and it will be implemented from January 1, 1997, and the original “Steam Boiler Safety Technology Supervisory Regulation” (LaoRenGuo 1987 No.4) will be annulled on the same date. If the existing regulations of our ministry are in conflict with the new regulations, the new regulations shall govern.The labor departments at all levels and the units relevant shall organize the personnel concerned to study and implement conscientiously the new regulations. Any problem occurred during the implementation, please inform the Supervisory Bureau of Occupational Safety and Health and Boiler Pressure Vessels of our Ministry.
