Lockout/Tagout (LOTO)
A safety procedure that isolates and secures energy sources so equipment cannot be started unexpectedly during maintenance.
Definition
Lockout/Tagout (LOTO) is a safety procedure that de-energizes, isolates, and physically secures energy sources on equipment so it cannot be unexpectedly started while technicians are working on it.
LOTO basics
A compliant LOTO procedure typically covers:
- Identifying every energy source (electrical, pneumatic, hydraulic, stored)
- Shutting down the equipment using standard procedures
- Isolating each energy source
- Applying lockout devices and tags, uniquely identified per technician
- Verifying zero-energy state before starting work
- Controlled release and start-up when work is complete
LOTO in a CMMS
A CMMS supports LOTO by attaching the procedure, verification checklist, and acknowledgement to the work order. Technicians can't mark a task started until the LOTO steps are confirmed on mobile, with photo evidence if required.
LOTO in FacilityLane
FacilityLane ties LOTO procedures to assets and asset classes. When a high-risk asset is on a work order, the correct procedure, lock assignments, and sign-off steps appear on the technician's mobile device — with the full record retained for audits.
FAQ
Common questions about Lockout/Tagout (LOTO).
Many jurisdictions require LOTO for servicing of machines where unexpected energization could injure workers (for example OSHA 29 CFR 1910.147 in the US). Local rules vary — check your jurisdiction.
