Lockout/tagout basics

Machines and circuits can start up while someone is working on them. Lockout/tagout keeps energy off until you are done.

Key points

• Know every energy source: electrical, hydraulic, pneumatic, stored springs.
• Shut down, isolate, lock and tag each source.
• Test that it is really off before you start.
• Only the person who placed a lock removes it.
• Tell everyone affected before and after.

Ask the crew

• What equipment on this job needs lockout today?
• Does everyone have their own lock?
