“I thought the power had been cut off…”
“I thought no one would start it…”
“I thought just putting up the sign was enough…” In industrial accidents, “I thought” is often the fatal culprit.
How to eliminate human errors? How to make safety no longer rely on “luck”?
Today, we use LOTO to implement the nine-step method and break down a standardized process that can truly lock down risks.
The 5 key points for preventing human errors Physical locks → Irreplaceable barrier
It is strictly prohibited to use “lockout tag” instead of the locking valve sleeve, personal lock, collective lock box… The hardware must be in place.
Zero energy verification → Breaking away from empiricism
Not relying on “feeling” or “experience”, but only through trial startup confirmation
If verification fails, immediately re-isolate.
One lock per person + collective lock box → No cross-responsibility
Each person locks their own life
When multiple people are working, all isolation point keys are placed in the box, and each person locks the box
The equipment cannot be restored if any person fails to unlock it
Face-to-face handover → Zero information loss
All shifts are unlocked during the day, and all shifts are locked at night
Prohibit handover via phone or notes
Homogenized management + engineering renovation → No excuses left
External personnel and contractors must follow the same LOTO procedures and jointly review the isolation plan
If the old equipment has no keyholes? Engineering renovation (installing keyholes, modifying switches) is not an option for exemption.
Summary in one sentence:
LOTO is not just a piece of paper, a lock, or a training program; it is a complete system that prevents “errors” from causing harm.
From leadership commitment to on-site execution, from energy identification to trial startup verification, at every step it is saying:
Safety cannot be achieved by luck; it can only be achieved through a closed-loop system.
Make LOTO move from “knowing” to “doing”
Have you ever encountered these problems?
You have established the LOTO system, but the on-site implementation was just a formality.
Employees couldn’t remember the nine-step method, and the trial start verification was often overlooked.
The external contractors were not cooperative, and the old equipment couldn’t be locked.
Only after the accident occurred did it become clear that “the locks were just for show and the signs were just a formality.”
