  2. Section I Introduction

  3. Introduction • Lockout/tagout • Employees • Energy sources

  4. Introduction • Amount of energy • Procedures • Tagout

  5. Introduction • Testing, positioning • Shift changes • Group lockout

  6. Section II What is lockout/tagout?

  7. Lockout/tagout (LOTO) Prevents injury: • Servicing • Maintenance

  8. Lockout/tagout (LOTO) • Locks • Tags • Stop energy flow

  9. LOTO devices • Locks • Blanks • Blinds • Covers

  10. LOTO devices • Lockout/tagout only • Durable • Standardized • Identify employee

  11. Service/maintenance • Construct • Install • Set up • Adjust • Inspect

  12. Service/maintenance • Modify • Lubricate • Clean • Clear jams • Tool changes

  13. LOTO during normal production • Remove/bypass guard • Body in point of operation
