Lock the valves or parts of the following key pipelines: 1) Electric energy: current or voltage, etc.; 2) Kinetic energy: running equipment, etc.; 3) Potential energy: steam (any pressure), compressed gas (above 0.1mpa), vacuum, pressurized liquid (above 0.1mpa), hanging basket, etc. 4) Chemical energy: dangerous chemicals, etc.; 5) Thermal energy: steam, hot water, ice water, cold water system, etc. 5, Lockout tagout follow the principle is: can lock not separate tag, lock certain tagout.
