Lockout/Tagout Glossary (Control of Hazardous Energy 1910.147)

OSHA’s lockout/tagout standard (Control of Hazardous Energy, 1910.147) consistently appears on OSHA’s list of the 10 most commonly cited violations.

As a result, we’ve created this interactive glossary of terms defined in the standard to help you brush up on some of the key concepts.

In addition to this post, we’ve pulled together a second post with a bunch of materials related to lockout/tagout.

Enjoy this one and then move on to the next if you’re interested.

A few important notes: The terms and definitions were taken directly from the text of the standard as printed on OSHA’s website in October, 2012. Convergence Training makes no claims regarding the accuracy of those definitions, nor to keep this glossary up to date to match any changes OSHA makes after the date of this posting.
