Lockout/Tagout, or LOTO, is a hazardous energy control system used to prevent machinery from being accidentally started during maintenance or servicing activities. It is considered a critical safety measure that helps reduce serious accidents such as crushing injuries, electric shocks, or unexpected machine operation.
The core principle of LOTO is to “isolate, disconnect, lock, and tag” all energy sources before work begins, while also verifying that no residual energy remains in the system.
Today, LOTO has become an international safety standard adopted by industrial facilities worldwide because it effectively reduces fatalities and helps build a strong safety culture within organizations.
