Zero energy state
When operating on equipment or systems, ensure that all dangerous energy sources that could cause harm to operators are isolated and locked, and are not accidentally released.
A more reliable isolation of hazardous energy sources including inflammable, explosive, toxic and harmful substances by means of physical disconnection, including the following ways:
Remove the disconnected part of the pipe or add a blind plate to plug it
Remove the fuse from the electrical system
Disconnect pipe connection
Before energy isolation, consider...
Can a single device/system implement the LOTOTO SOP?
Can the system or device be quarantined? Can it be locked?
Or is it controlled with a LOTOTO license?
Scope of application
"Applicable in the maintenance work of the machine/equipment, which may be caused by accidental electrification, or the machine started or stored energy released by two teams of employees."
Typical jobs may include:
Replacement and disassembly of repair and reconstruction parts, adjustment, plugging clearance, lubrication and cleaning inspection
