– Develop lockout procedures

Lockout Procedures

• Lockout Sequence1. De-energize

2. Apply locks

3. Verify lockout

Lockout Procedures

• Lockout Sequence - continued

4. Interlocks

5. Release energy sources

6. Lock removal

7. End of shift transfer

Lockout Procedures

• De-energize

– Identify the energy sources

– De-energize and isolate

– If complicated, “qualified person” must de-energize

Lockout Procedures

• Apply locks

– Each worker attaches his/her own lock

– Cables cannot be used for more than 4 switches

Lockout Procedures

• Verify lockout

– First person to apply lock tests lockout

– Test from the operator’s console

– Disable computer controls or interlocks

– Attempt a soft start on computer systems

Lockout Procedures

• Interlocks

– Upstream interlocks can give false reading

– Must be noted in written procedures

Lockout Procedures

• Release Energy Sources

– Ensure all sources are released

– Written procedures should address this

Lockout Procedures

• Lock Removal and Re-starting

– Remove all tools

– Guards in place

– Notify affected employees

– Equipment in neutral

– Each worker removes his/her own lock
