Every year, OSHA estimates that proper lockout/tagout compliance prevents roughly 120 deaths and 50,000 injuries among American workers. Those aren’t projections from a worst-case model — they’re the gap between what’s supposed to happen on a maintenance floor and what actually happens when a procedure gets skipped because the line needed to come back up five minutes faster.

The numbers behind that gap are sobering. In 2023 alone, the Bureau of Labor Statistics recorded 226 deaths in the category of workers struck, caught, or compressed by running powered equipment — and 48 of those deaths occurred specifically during maintenance, cleaning, or testing, the exact windows when a machine should have already been de-energized and verified safe. Between 2022 and 2023, OSHA’s Severe Injury Reports also logged nearly 19,700 severe injury cases — hospitalizations and amputations — with “caught in or compressed by machinery” as the single leading cause.

Look back further and the pattern holds. A landmark study of United Auto Workers fatalities between 1973 and 1995 found that 20% of all member deaths — 83 out of 414 — were directly tied to inadequate hazardous energy control. Decades of regulation later, the Control of Hazardous Energy standard (29 CFR 1910.147) still ranked among OSHA’s top five most cited violations in fiscal year 2024, with over 2,400 citations issued. This isn’t a solved problem. It’s a problem we’ve gotten better at — not one we’ve eliminated. Occupational Safety and Health Administration + 3
And the injuries that do happen aren’t minor. Workers hurt by uncontrolled hazardous energy lose an average of 24 workdays recovering, and many never return to the role they had before the incident. One review of electricity-related accident reports found that 80% of injured workers had not received proper LOTO training beforehand. The failures aren’t usually about people not caring. They’re about systems that don’t catch the gap until it’s too late. LegalClarity + 2
Why LOTO Keeps Failing — Even When Everyone Knows Better
Production pressure is the single biggest driver. When a line is down and the schedule is tight, the lockout procedure starts to feel like the thing standing between “we hit our numbers” and “we don’t.” Workers shortcut the verification step. Supervisors reset equipment without confirming who’s still inside the danger zone. A second technician shows up to help and nobody checks whether the first one is still locked in.
None of this happens because people are careless. It happens because paper-based and verbal LOTO tracking has no way to physically stop the unsafe action from occurring. A binder doesn’t know a machine is currently locked out by someone else. A whiteboard doesn’t alert a supervisor when an authorized lock has been on a machine for six hours past a normal service window. The system trusts that everyone follows the process — it doesn’t enforce it.
How Primus Maintain Closes That Gap
This is exactly the problem Primus Maintain was built to solve — not by adding more paperwork, but by making non-compliance structurally impossible at the point where it would otherwise happen.
Multi-technician LOTO, logged individually. When a work order involves more than one authorized technician — which is common on larger equipment or longer service windows — Primus requires each technician to log their own LOTO independently, tied to their identity, not a shared sign-off. There’s no single “the crew locked it out” entry that obscures who actually applied a lock and who didn’t.
The system won’t let a second technician walk onto an active call without their own lock. If Technician A is already logged into LOTO on a work order, Primus will not allow Technician B to join that same work order without going through their own lockout step first. This isn’t a checkbox reminder — it’s a hard gate. The exact failure mode in so many real incidents — “I assumed someone else already locked it out” — is structurally prevented, not just discouraged.
Active LOTO status is visible in real time, to the people who need to see it. Every currently active lockout shows directly on the main dashboard — not buried in a report someone has to go looking for. A supervisor walking the floor, or sitting in the office, can see at a glance exactly which machines are locked, by whom, and for how long. There’s no gap between “the lockout happened” and “management knows it happened.”
Every lockout event is auditable after the fact. Compliance isn’t just about preventing today’s accident — it’s about being able to prove, months later, that your organization had a real, enforced energy control program in place. Primus keeps a complete, timestamped audit trail of every LOTO event: who applied it, when, on what asset, and when it was released. When an auditor, an insurer, or OSHA itself asks for evidence of your program, you’re not reconstructing it from memory — you’re pulling it up.
This Isn’t a Nice-to-Have
A CMMS that simply records that LOTO happened is doing the bare minimum — and the bare minimum is exactly what’s been failing for fifty years of regulation. The data is clear: training gaps, production pressure, and systems that rely on trust rather than enforcement are still costing workers their lives and their limbs, every single year.
Multi-technician lockout logging, hard gating against unsafe entry, real-time dashboard visibility, and a defensible audit trail aren’t features for organizations that are merely checking a box. They’re foundational for any organization that is serious about compliance — and more importantly, serious about the safety of the authorized and affected employees standing in front of that machine.
The procedure on paper has never been the problem. The gap between the procedure and what actually happens on the floor — that’s where people get hurt. Primus Maintain exists to close that gap.
