During the process of controlling the procedure, the procedure shall be reviewed and continuously improved.
2 dangerous energy control procedures and contents
2. Scope and purpose
The program is mainly applicable to equipment repair and maintenance. Unexpected "energy supply", "equipment start-up", "storage energy release" and other problems may cause dangerous energy injury to personnel during the repair and maintenance of equipment. So, the goal of the program is to reduce dangerous energy damage.
2.2 terms and definitions
(1) dangerous energy is uncontrolled, which may cause human injury. Energy -- in the form of gravity, electricity, machinery, chemistry, hydraulics, air pressure, heat -- can be a dangerous source if left unchecked.
(2) energy isolation device is a mechanical device that physically blocks the transmission or release of dangerous energy, such as manually operated electrical circuit breaker, electrical isolation switch, electrical load switch pipeline valve, blind plate, etc.
(3) Lockout tagout is the specific practices and procedures used to protect employees from dangerous energy during equipment repair and maintenance, as well as the safety management methods that apply these specific practices and procedures
(4) locking means to install locks on the energy isolation device according to the process of locking and listing to ensure that the energy isolation device and the controlled equipment cannot be operated until the locks are removed.
Key factors include inspection requirements, inspection technology, accessibility requirements, equipment geometry dimensions, and selection of component materials.
The design of the equipment should minimize the number of parts to be inspected. On the premise of not affecting the reliability of the equipment, for the equipment with a variety of design methods, the design with lower inspection requirements should be adopted. Not only to ensure the reliability of the equipment, but also to reduce the difficulty of inspection, and inspection personnel's radiation dose. In addition, the selection of design method should be in line with the current manufacturing technology level, and the requirements far beyond the current manufacturing technology level should not be put forward in order to reduce the number of inspection parts in service. Therefore, on the premise of meeting the accessibility requirements of in-service inspection, the design method with lower manufacturing difficulty can not only meet the requirements of equipment reliability and accessibility, but also reduce the manufacturing cost.
