Use case
Lockout tagout procedure: every isolation point, every time
A digital lockout tagout procedure with AR: every isolation point shown on the machine, every lock confirmed, and a full record of each LOTO for audits.

In short
A lockout tagout procedure (LOTO) is the sequence for isolating all energy sources of a machine and securing them with a lock and tag before work starts. Actarion turns your machine-specific LOTO procedures into digital steps with AR: each isolation point is shown on the machine and every lock is confirmed and logged.
How it works on the shop floor
How does a digital LOTO procedure work?
- 1
Inventory energy sources
per machine: electrical, pneumatic, hydraulic, mechanical, thermal and stored energy.
- 2
Build the procedure.
AI structures your existing LOTO sheets into steps with photos of each isolation point.
- 3
Guide on the machine.
AR shows where each isolation point is, in the right order.
- 4
Confirm each lock.
The technician confirms with a photo or scan per point.
- 5
Verify zero energy.
The try-out or measurement is a mandatory step.
- 6
Release in reverse.
Removal of locks follows the same guided sequence and is logged.
Where does LOTO fail in practice?
- A second energy source, such as compressed air or stored pressure, is overlooked.
- The procedure on paper does not match the machine after a modification.
- The zero-energy check is skipped under time pressure.
- Contractors do not know your machines or your LOTO rules.
What do you measure?
| KPI | What it shows |
|---|---|
| LOTO compliance in audits | Share of correctly executed isolations |
| Machines with a specific LOTO procedure | Coverage of your machine park |
| Near misses related to energy isolation | Safety trend |
| Time per isolation | Efficiency without cutting corners |
Rules and standards
In the US, OSHA 29 CFR 1910.147 requires energy control procedures, training and periodic inspections. In Europe, the Use of Work Equipment Directive 2009/104/EC requires that equipment can be isolated from energy sources. ISO 45001 asks for controlled procedures for hazardous work. A digital record helps you show compliance.
Results you can expect
Complete isolations, up-to-date procedures per machine and evidence for every LOTO.
Hardware you need
- Tablet for the procedure and photo confirmation.
- AR glasses for large installations with many isolation points.
How to start a pilot
Choose a few machines with several energy sources. Use our lockout tagout procedure template to collect isolation points. Plan your pilot.
Common mistakes in a pilot
- Digitizing without checking the procedure. Walk every isolation point on site first; outdated LOTO sheets are common.
- Skipping the verification step. The try-out (zero energy check) must be a mandatory step with confirmation.
- Leaving out contractors. They often carry the highest risk, so give them access to the same guided procedure.
How Actarion helps
- AI turns your LOTO sheets into machine-specific digital procedures.
- AR shows each isolation point on the machine.
- Mandatory confirmations prevent skipped steps.
- The audit trail proves who isolated what and when.
