Beyond the minimum
- Stored and residual energy checklist: springs, hydraulics, pneumatics, capacitors, gravity, thermal, flywheels, pressurized chemical lines.
- Multiple and hidden energy sources, and practical methods for controlling stored energy.
- Verification and try-out pitfalls, including returning controls to off and testing the tester.
- Common shift-change practice: oncoming worker locks on before off-going worker removes.
- Electrical work note: 29 CFR 1910.333(b)(2) lock-and-tag, qualified-person testing, and NFPA 70E.
- Citation data: lockout/tagout ranked 3rd on OSHA's preliminary FY2026 most-cited list (1,863 citations), most-cited subparts, and typical scenarios.
- OSHA estimate that compliance prevents about 120 fatalities and 50,000 injuries per year.
What your employer provides
Employers remain responsible for training on their own machine-specific energy control procedures and certifying training under 1910.147(c)(7)(iv).
The certificate
Lists your name, the standard, the completion date, the valid through date, and a verification number with a QR code. Page two lists the training elements covered.
