Before you buy: what your employer must also provide

For affected and other employees this course covers the awareness training in 29 CFR 1910.147(c)(7). For authorized employees who apply locks it is the classroom portion only: your employer must also train you on the actual machines, energy sources, isolation devices and written procedures at your site, and certify that training.

About this course

A machine that is switched off is not a machine that is safe. During servicing and maintenance, a coworker pressing a start button, a second power feed nobody knew about or pressure trapped in a cylinder can cause amputations, crushing injuries and deaths. The control of hazardous energy standard, 29 CFR 1910.147, exists to stop that, and it regularly appears on OSHA's list of the 10 most frequently cited standards.

You will learn what hazardous energy is, what the standard covers and what it excludes, including cord-and-plug equipment and the minor servicing exception. You will learn the difference between authorized, affected and other employees, the parts of an energy control program, lockout compared with tagout, the limitations of tags, and the annual periodic inspection. You will work through the 6-step sequence for applying energy control, the release sequence, testing and positioning, group lockout, shift changes, outside contractors and the strict rules for removing a lock applied by someone else. Scenarios come from electronics assembly, machining, metal fabrication and warehousing.

What this course covers. For affected employees and other employees, this course covers the training content required by 29 CFR 1910.147(c)(7)(i)(B) and (C). For authorized employees, it is the classroom portion only. Before anyone locks out a machine, the employer must also train them on the specific machines, energy sources, isolation points, devices and written procedures they will use, with hands-on practice, and certify that training. The course does not make anyone an authorized employee and is not OSHA certified or approved; OSHA does not approve training providers. It teaches federal OSHA general industry requirements; state-plan states such as California may add requirements, and employers outside the United States follow their own regulations.

The course closes with a 10-question examination drawn from a bank of 20. On passing you receive a PlanetISO Certificate of Completion for the instruction delivered online, with lifetime access to the course. The certificate does not expire, but the standard requires retraining whenever your job, equipment, hazards or procedures change.

Explain the scope of 29 CFR 1910.147, including the cord-and-plug and minor servicing exceptions.

Questions

Does this course meet OSHA's lockout/tagout training requirement?

For affected employees and other employees, it covers the training content 29 CFR 1910.147(c)(7)(i)(B) and (C) requires; your employer should add the specifics of your site, such as what your locks and tags look like and who to call. For authorized employees it is the classroom portion only. The employer must add hands-on training on the actual machines, energy sources, isolation points and written procedures, and certify the training with names and dates.

Will this course make me an authorized employee or OSHA certified?

No. Your employer designates authorized employees after training them on the equipment they service. OSHA does not certify workers in lockout/tagout and does not approve training providers. You receive a PlanetISO Certificate of Completion for the instruction delivered online.

Is lockout/tagout training required every year?

The standard does not set a fixed retraining interval. It requires an annual periodic inspection of each procedure and retraining whenever job assignments, equipment, hazards or procedures change, or when the inspection or the employer finds gaps in knowledge. Many employers choose annual refreshers.

Is OSHA changing the lockout/tagout standard?

OSHA asked for public input in 2019 on control circuit type devices and robotics, and its regulatory agenda lists a proposed update to 1910.147 (RIN 1218-AD00), with a proposed rule targeted for November 2026. A proposed rule does not change the law; only a final rule does. As of October 2026 the standard remains as issued in 1989 with later amendments. Until a final rule takes effect, push buttons, selector switches and other control circuit devices are not energy isolating devices.

What certificate do I receive and does it expire?

A PlanetISO Certificate of Completion showing the course title, your name and your exam result. It does not expire. Retraining is still required whenever the triggers in 1910.147(c)(7)(iii) occur.

What happens if I fail the exam?

You have 3 attempts. Each attempt draws a different 10-question set from the bank of 20, and module quizzes can be retaken without limit to prepare.
