What is Lockout Tagout?
What is Lockout Tagout (LOTO)?
Lockout Tagout (often shortened to LOTO) is a safety procedure used to help prevent unexpected start-up or release of hazardous energy while equipment is being serviced, maintained, or repaired.
Quick overview
LOTO helps protect workers by ensuring machinery and systems are properly isolated and cannot be re-energised until work is complete. It typically involves physical lockout devices and safety padlocks, combined with tags and clear procedures.
- Identify energy sources (electrical, mechanical, hydraulic, pneumatic, thermal, etc.)
- Isolate energy and apply a lockout device + safety padlock
- Tag the isolation point and verify zero-energy state
- Maintain control until work is complete and safe to restore
Lockout Tagout FAQs
Why is Lockout Tagout important?
LOTO helps reduce the risk of injury by preventing unexpected energisation or release of stored energy during servicing and maintenance activities.
What types of energy does LOTO control?
Common energy sources include electrical, mechanical, hydraulic, pneumatic, chemical, and thermal energy, as well as stored energy in springs, pressure systems, or elevated loads.
What LOTO devices are typically used?
Many sites use safety padlocks, lockout hasps, breaker lockouts, valve lockouts, lockout tags, and lockout stations. The right selection depends on the equipment and isolation points on your site.
Do you provide Lockout Tagout training?
Yes. We can deliver on-site lockout training at your workplace, including practical guidance on procedures, device selection, and implementing a consistent approach across teams.
Can you help us assess our current LOTO setup?
Yes. We offer site-based gap analysis assessments to review your existing lockout equipment and procedures and identify what’s missing or what could be improved.
