Lockout tagout (LOTO) is the practice of physically locking a machine’s energy source in the off position and tagging it with the worker’s name before anyone services or repairs it. It stops equipment from starting up or releasing stored energy while a person’s hands are inside it. In the US, it’s governed by OSHA standard<\/a> 29 CFR 1910.147, and it’s one of the most cited standards on OSHA’s annual violation list.<\/p>\n\n\n\n

I’ve walked into plants where the LOTO binder looked perfect on paper and still watched a maintenance tech get a hydraulic ram drop on him because nobody bled the accumulator. The procedure existed. Nobody followed the part that mattered. That gap between having a program and doing the isolation right is what this guide actually covers.<\/p>\n\n\n\n

LOTO is short for lock out, tag out. You’ll also see it written as “lockout\/tagout” or “lock, tag, and try,” and that third version isn’t just wordier for no reason. It reflects a real addition to the practice: the “try” step, where a worker attempts to start the equipment after locking it to prove the isolation actually worked.<\/p>\n\n\n\n

The federal standard behind it, 29 CFR 1910.147, was written in 1982 and became enforceable in 1989. Before that, plants relied on verbal warnings and “don’t touch” signs, which is exactly as unreliable as it sounds. The rule exists because tags alone don’t stop a machine from restarting. Only a physical lock does.<\/p>\n\n\n\n

The Energy Types Your Procedure Has to Account For (Not Just Electrical)<\/h2>\n\n\n\n

Most people think LOTO and picture a breaker panel. Electrical is the one everyone remembers. It’s also the one that gets people hurt least often in my experience, because it’s the most obvious. The energy that catches techs off guard is the kind that’s invisible after the main switch is already off.<\/p>\n\n\n\n
