Ten principles of locking and hanging out
1. Identify possible dangerous energy sources before starting the Lockout Tagout;
2. Before the operation, make sure the relevant energy isolation measures in the work are in place;
3. In the places where the lock can be used, the labels shall not be separately hung. In the places where the lock cannot be used, special procedures shall be developed to hang labels and measures shall be taken equivalent to those taken before the lock is used.
4. Personnel entering the locked area should be aware of the risks to which they may be exposed;
5. Communicate Lockout tagout status with relevant operators in time;
6. Before energy removal and isolation, the hazards of energy should be clearly identified;
7. To compare the effectiveness of energy isolation measures;
8. For all electrical hazards, a power off test must be performed;
9. Isolating the "power source" is more important than saving time, money, hassle, convenience, or productivity at all times;
10. "Locking up" and "Do Not Danger" are sacrosanct measures.
