Lockout/Tagout (LOTO) Procedure

Use it for any machine, line, vessel, panel, or utility that can store or release hazardous energy during servicing or maintenance. That includes electrical, hydraulic, pneumatic, mechanical, thermal, chemical, and gravity energy sources. If the task requires a guard removal, body entry, or reaching into a danger zone, this template is usually relevant. Adapt the scope section to match your site’s equipment list and energy isolation points.

Use it every time authorized work requires isolation of hazardous energy, not just for major shutdowns. It also applies to routine servicing, troubleshooting, cleaning, jam clearing, and changeover tasks when exposure to energy is possible. If your site has recurring tasks, keep the procedure tied to the job plan so it is used consistently. The template can also support periodic review and revalidation after equipment changes.

The procedure is typically initiated by a supervisor or maintenance lead, executed by an authorized employee, and verified by a competent person. Affected personnel should be notified before shutdown, and operators may perform normal shutdown steps if the procedure assigns them that role. The key is that only trained and authorized people apply or remove locks and tags. Your customization should clearly define each role to avoid confusion at the point of work.

Yes, it is designed to support hazardous energy control practices commonly expected under OSHA-style lockout/tagout programs. It also helps create documented information that aligns with ISO 9001 recordkeeping expectations when you need evidence of controlled execution. If your site uses permit-to-work, confined space, or contractor control processes, this procedure can be linked to those workflows. Always adapt it to your local legal and site-specific requirements.

The biggest failures are skipping notification, isolating only the obvious energy source, and assuming a machine is safe without verifying stored energy release. Another common issue is using a lockout device without a clear tag, role assignment, or removal control. This template also helps prevent maintenance from starting before zero-energy verification is complete. It is especially useful where multiple trades or contractors work on the same asset.

Yes, and you should. Multi-energy equipment often needs separate isolation points, verification steps, and escalation rules for missing or inaccessible disconnects. Group lockout may require a lock box, primary isolator, or individual personal locks with a clear removal process. Customize the steps so the procedure matches the actual equipment and the number of people involved.

An ad-hoc checklist may remind people to shut equipment down, but it usually does not define roles, verification, escalation, or documentation. This template turns the task into a controlled procedure with atomic steps and clear accountability. That matters when multiple energy sources, contractors, or shift handoffs are involved. It also creates a repeatable record for audits and incident investigations.

It works well with permit-to-work systems, maintenance work orders, inspection logs, training records, and asset registers. In IT or facilities contexts, it can also be linked to change management or service runbooks when equipment isolation affects operations. If your organization tracks non-conformance or corrective actions, connect the procedure to those records when a deviation is found. The goal is to make isolation, maintenance, and release traceable end to end.
