Lockout/Tagout(LOTO) is one of the most critical safety programs in any industrial setting. If your employees service, maintain, or clean equipment where unexpected startup or stored energy could cause injury, this applies.
LOTO falls under OSHA’s Control of Hazardous Energy standard (29CFR 1910.147). The requirement is simple: hazardous energy must be fully isolated before work begins.
If you have machines with electrical, mechanical, pneumatic,hydraulic, or stored energy, you need LOTO.
Machine shops, manufacturing facilities, food processing plants,and maintenance-heavy operations all fall into this category.
If equipment can start unexpectedly or release stored energy, LOTOis required.
Not just maintenance.
There are three groups:
Authorized employees require the most detailed training. They are responsible for identifying and controlling all energy sources.
Before any servicing or maintenance work begins.
Retraining is required when:
In addition, OSHA requires periodic inspections of LOTO procedures at least annually.
LOTO training is not generic. It must match your actual equipment.
OSHA requires machine-specific energy control procedures thatinclude:
Authorized employees must also understand:
This is where most serious incidents happen. Missing a single energy source can be enough to cause severe injury.
As one safety professional put it, “If all energy sources are not identified and communicated…we are placing their lives in jeopardy.”1
Most LOTO issues are not about having a program. They are about incomplete procedures.
Typical gaps include:
Real-world incidents often come down to something small being missed. In one case shared by a safety professional, stored spring tension was not identified in a machine, even though power and air were locked out, resulting in a serious hand injury.1
Do not over-complicate it.
Start with your actual equipment. Identify every energy source, including stored energy. Build machine-specific procedures that walkthrough shutdown, isolation, lockout, and verification step by step.
Then train employees based on their role and document everything.
In practice, OSHA is looking for three things:
Common documentation includes machine-specific procedures,training records, and annual inspection records.
Tip: Use MakerComply’s Free Employee Training Tracker to keep clean, consistent records without the usual admin headache.
LOTO is not about locking out power. It is about controlling all hazardous energy. If even one source is missed, the system fails.
This cheat sheet is meant to be an overview and does not take the place of full regulatory compliance guidance. Consult OSHA standard 29 CFR 1910.147 for full requirements.
