LOTOTO = Lock Out - Tag Out - Try Out
Before you begin: Everyone needs his own lock and tag (label), which can’t be removed by other persons. Inform all the persons who
are influenced by the procedure.
1 To block
- Localize all sources of energy (electric, hydraulic, pneumatic).
- Switch off.
- Take the relevant installation or process out of operation and lock it against reuse. You can do this by placing a
padlock or other blocking mechanism (Lock Out).
2 To mark
Attach a sign, label or sticker to the padlock or blocking mechanism to reveal the nature and the expected duration of
the work to other persons (Tag Out).
3 To check
- Check if the source of energy is switched off.
- Remove any remaining energy.
- Check that the installation or process is actually safe (Try Out).
