Most LOTO programs that “have procedures” actually have files: a Word doc per machine on a shared drive, a spreadsheet tracking which ones were reviewed, and a laminated printout at the asset that may or may not match either. It works until the week it matters: an audit, an equipment change, or a night-shift job on the far side of the plant.
This guide compares Excel-and-Word LOTO management against purpose-built digital LOTO software on the dimensions that change compliance outcomes: version truth, field access, inspection tracking, and audit proof. It also covers what free software actually covers and a migration plan that does not require rewriting everything in a weekend.
Where Excel and Word break down
Spreadsheets track documents; they do not control energy. The three failure moments are the same in nearly every plant that outgrows files:
- The update: a drive gets swapped or a valve relabeled, the Word file gets revised, and the laminated copy on the machine stays old for a year. Nobody knows which version is true.
- The access: the current file lives three folders deep under a retired tech’s naming scheme. The night shift works from memory instead.
- The proof: annual inspection dates in a spreadsheet with no certifications, training rosters in email, deviations in someone’s notebook. Reconstructing the file for an inspector takes days and still comes up short.
Side by side: files vs. purpose-built software
Evaluate against the weekly workflow (author, deploy, scan, audit), not the feature list:
| Capability | Excel + Word + shared drive | Digital LOTO software |
|---|---|---|
| One current version per machine | No, copies fork; filename discipline decays | Yes, single record with revision history |
| Photos at isolation points | Buried in folders or missing | Attached to the step that uses them |
| Field access at the asset | Binder hunt or folder search | QR scan opens the live procedure, no app install |
| Offline coverage | Printed copy (possibly stale) | PDF exported from the live record, with the same QR code |
| Annual inspection tracking | Manual spreadsheet dates | Due dates per procedure + automatic certification |
| Deviations to closure | Lost on paper | Logged with owners and dates |
| Multi-site consistency | Each site invents its format | One format, company → site organization |
| Audit export | Days of assembly | Per-asset PDF in minutes |
The benefits that actually change the compliance math
Software does not replace training, verification discipline, or leadership on the floor. What it removes is the administrative decay that lets good programs drift into citations:
- Version truth: one current procedure per machine, with history. The stale-laminate problem disappears because the QR scan always serves the live record.
- Speed at the machine: a scan beats a binder hunt. Adoption follows because the new way is faster than the old way.
- Inspection integrity: every procedure carries its due date; every completed inspection writes the required certification (machine, date, employees, inspector) automatically.
- A digital checklist that lives with the procedure: the compliance checklist becomes due dates and owners instead of a once-a-year paper exercise.
- Records an inspector understands: per-asset PDFs with scope, energy table, photos, verification, and restart steps map directly to 1910.147(c)(4).

When spreadsheets are still enough, honestly
Software is not mandatory at every size. Files remain defensible when the program is genuinely small: fewer than about 10 machines, single energy sources, one site, low turnover, and a disciplined owner who reviews every procedure annually and keeps printed copies current by hand.
The honest triggers to go digital: more machines than one person can track reliably, multiple energy sources or stored-energy traps, more than one site, auditors or insurers asking questions your files answer slowly, or procedure updates that take longer to distribute than to write. If two of those are true, the spreadsheet is costing more than the subscription.
What free LOTO software covers (and what it does not)
Free tiers are built for pilots, and that is how to use them. Tegis is free up to 25 procedures: enough to digitize a full line or cell with QR linking and PDF export, so a plant can prove the workflow before spending anything.
Expect free to cover authoring, QR access, and printable PDFs. Expect inspections at scale, multi-site administration, migration help, and support to sit in paid tiers. That split is standard across vendors. The right question is not “is it free forever” but “does the free pilot produce a procedure my techs prefer over the binder?” If yes, the budget conversation becomes easy.
Migrating from Excel in three phases
Do not rewrite everything. Structure what you have, photograph what matters, and publish where the work happens:
- Phase 1: Pilot (weeks 1–3). Inventory files, pick 10–20 high-risk assets, convert existing Word/PDF content into structured procedures with fresh isolation photos, and run one department live.
- Phase 2: Deploy (weeks 4–8). Place QR tags where lockout work starts, keep posted PDFs as offline backup, and brief shifts at the machine on scanning and verifying the asset ID.
- Phase 3: Operate. Run the annual inspection cycle digitally, review coverage and deviation-closure monthly, and expand line by line. The full playbook is in the digital program guide and the software benefits checklist.
Key takeaways
- Files fail at the update, the access, and the proof: the three moments audits and incidents test.
- Software wins on version truth, QR field access, inspection tracking, and audit-ready PDFs, not on dashboards.
- Under ~10 simple machines with a disciplined owner, files can still work. Beyond that, the spreadsheet costs more than it saves.
- Use free tiers to pilot a real line: if techs prefer the scan over the binder, the rollout sells itself.
- Migrate in phases: priority assets first, QR tags at the machine, inspections digital from the first cycle.
Frequently asked questions
What are the main benefits of LOTO software over Excel?
One current version per machine with history, photos attached to isolation steps, QR access at the asset without an app, automatic annual-inspection certifications, deviation tracking to closure, and per-asset PDF exports. Excel tracks filenames; software tracks the procedure content itself.
Is there free lockout/tagout software?
Yes: Tegis is free up to 25 procedures with QR linking and PDF export, which covers a pilot line or a small shop. Larger programs with many sites, inspection volume, and support needs run on paid tiers. Compare the free pilot on authoring speed and field preference, not on how long free lasts.
How do we migrate LOTO procedures from Excel and Word?
Inventory existing files, rank assets by risk and servicing frequency, and convert the top 10–20 into structured procedures with fresh isolation photos. Tag those assets with QR codes, keep posted PDFs as backup, and run the first inspection cycle in the new system before expanding line by line.
Do digital procedures and PDFs satisfy OSHA?
Yes. OSHA requires documented, accessible, current procedures and certified inspections; the standard does not mandate paper. Digital records satisfy it when the current procedure is available at the point of work (QR plus mobile view) with a printed PDF fallback for offline areas.
Can we keep using our digital LOTO checklist and PDFs alongside software?
That is the intended bridge: the checklist becomes scheduled inspections with owners in the software, and PDFs become disposable snapshots of the live record, posted at assets, packed for contractors, and handed to inspectors. The live procedure stays the system of record; paper stops being a competing version.
