One machine, five energy families
The classic failure is partial isolation: the breaker opened, the line still charged. Tegis structures every energy source as its own step, so none get skipped.

Lockout/tagout software for chemical plants
Chemical machines rarely have one energy family: process lines, steam, nitrogen, gravity, and thermal mass meet at the same equipment. Tegis documents each source with its own isolation, release, and verification step, and puts the current procedure behind a QR code at the asset.
- Multi-energy isolations documented step by step
- Stored-energy release and verification written into every procedure
- QR scan at the asset opens the approved procedure, no app
Built for multi-site programs
Where chemical-plant LOTO fails
Stored energy lives in procedure prose
Accumulators, trapped pressure, gravity-fed headers, and thermal mass need explicit release devices and pass criteria, not a sentence buried in a paragraph.
Turnarounds multiply the exposure
Contract crews, overlapping jobs, and shared isolation points need documented group lockout and 1910.147(f)(2) briefings, not whiteboard coordination.
Built for complex isolations
The detail a chemical-plant procedure needs, structured per asset.
Every energy source named
Type, magnitude, location, isolation device, and verification per source, with the units the field uses: PSI, InHg, °F, LBS.
Stored energy gets its own step
Release devices, bleed and drain points, and pass criteria written between isolation and verification, where inspectors look for them.
Verification you can test
Each step carries its verification text: gauge reads zero, no flow, no motion. Observable criteria, not “check that it is safe.”
Group lockout documented
Hasp and lockbox device types are built in for crew jobs, with each worker applying and removing their own lock.
Contractor coordination
Share the QR-linked procedure as part of the outside-personnel briefing, and keep it documented in the same system.
One record per asset, unit by unit
Management-of-change updates land in the record once, and the affected PDFs regenerate for the field.
Who runs it
EHS owns it
One current version per asset, owners assigned per site.
Maintenance uses it
Scan at the asset, no binder hunt, no search box.
Corporate sees it
Company → site → asset. Every plant, same standard.
Start with the machine everyone avoids
Pick the multi-energy machine
The unit with nitrogen, steam, and process chemicals on the same skid. If the workflow holds that one, it holds the plant.
Document it with the people who break the lines
Capture every isolation point, release device, and verification criterion with photos while the crew that knows the machine is in the room.
Tag the asset and brief the units
Link the QR code at the isolation point and give contractors the same scan during turnaround briefings.
Chemical plant LOTO questions, answered
We run PSM. Does this overlap with 1910.119?
LOTO records feed process safety information under 1910.119. Tegis keeps the LOTO side current, structured, and exportable. It is not a PSM system and does not replace one.
Can it handle line breaks, drains, and trapped pressure?
Yes. Stored-energy release is a first-class step with device, location, and pass criteria, not a comment field.
How does it handle group lockouts during turnarounds?
Hasp and lockbox device types are built in. Each worker applies and removes their own lock, and the step text documents the method for the audit trail.
How do contractors fit in?
The QR-linked procedure and its PDF support the host-contractor briefing required by 1910.147(f)(2), and every contractor worker applies a personal lock like any authorized employee.
What about radiation gauges and specialty instruments?
Radiation is a documented energy type with its own unit, and custom isolation-device text covers the hardware the standard options do not.
We have decades of legacy procedures. What is the migration path?
Convert the highest-risk units first, with our help. Old files become source material instead of the system of record.
Need the procedures written for you?
Provenio Consulting surveys equipment, authors machine-specific procedures, and delivers the program in a workspace your facility owns.
Walk one isolation with us.
Bring the machine your crew avoids and we will document its energy families live in the builder.
