Mastering Lockout/Tagout: 5 Steps That Break Down Most Often

Frequently Asked Questions

What lockout/tagout steps break down most often?

The post says the most common breakdowns are identifying energy sources, shutting equipment down in the right sequence, applying locks and tags to every isolation point, controlling stored energy, and verifying zero energy before work begins.

Why do LOTO failures still happen if we already have written procedures?

According to the post, most failures happen in field execution, not because a procedure exists. The biggest gap is when a clean written procedure does not match the real machine, the real job conditions, or the pressure workers face during non-routine work.

How can we improve lockout/tagout on complex equipment?

The post recommends equipment-specific procedures, reviewing procedures after modifications, and involving maintenance, operations, and engineering when mapping energy sources. It also calls for standardized hardware and labels, clear shutdown and verification steps, and field-friendly digital procedures.

What does zero-energy verification include during LOTO?

The post says verification should include trying the normal operating controls and confirming the equipment will not start, along with any necessary testing for electrical or other hazardous energy. On complex assets, more than one check may be needed.

How can digital LOTO procedures help workers in the field?

The post says digital procedures can guide workers through isolation points and shutdown steps in sequence, present the full list of required isolation points, and add prompts for verification. This can make complex lockout steps easier to follow and reduce missed isolation and verification actions.
