Why this matters
Equipment that starts unexpectedly can kill. Lockout makes sure it can't start while you work on it.
What to cover
- Identify every energy source: electrical, mechanical, hydraulic, pneumatic, and stored.
- Switch off and isolate each source.
- Apply your own lock and tag to each isolation point.
- Release or block stored energy.
- Test that the equipment can't start before you begin.
- Only the person who applied a lock removes it.
Ask the crew
- Who has the lockout kit?
- What energy sources does this equipment have?
- What do you do if you find someone else's lock on a disconnect?
One thing to do today
