  1. Electrical Safety – What you need to know to build an Electrical Safety Program William Rodeman Electrical Program Manager Land O’Lakes, Inc.

  2. Electrical Safety Energized Electrical Work Permit Electrical Hazards PPE Boundary Distances Boundary Distances Electrical Shock Arc Flash NFPA 70E

  3. Typical Questions: • What are the requirements around electrical safety? • What really are the hazards? • How do we protect employees? • What needs done to actually implement this program?

  4. What are the requirements around electrical safety? • What really are the hazards? • How do we protect employees? • What needs done to actually implement this program?

  5. What are the requirements around electrical safety? OSHA 29 CFR 1910.301-.399 (Subpart S) • CFR 1910 General Industry NFPA 70E Consensus Standard for Electrical Safety in the Workplace • Updated every 3 year • Current edition is 2018

  6. What are the requirements around electrical safety? OSHA • OSHA 29 CFR 1910.335(a)(1)(v): • Employees shall wear protective equipment for the eyes or face whenever there is a danger of injury to the eyes or face from electrical arcs or flashes or from flying objects resulting from electrical explosion. “What”

  7. What are the requirements around electrical safety? • NFPA 70E 130(C)(3): • Employees shall wear nonconductive head protection wherever three is a danger of head injury from electric shock or burns...If employees use hairnets or beard nets, or both, these items must be arc rated. • NFPA 70E 130(C)(10)(b)(1): • An arc-rated hood or an arc-rated balaclava with an arc-rated face shield shall be used when the back of the head is within the arc flash boundary. “How” NFPA 70E

  8. What are the requirements around electrical safety? • What really are the hazards? • How do we protect employees? • What needs done to actually implement this program?

  9. What really are the hazards? There are two (2) direct hazards when working on electrical equipment • Shock • Arc Flash

  10. What really are the hazards? Electrical Shock – Current passing through the body Magnitude of the Current Duration that Current Flows Through the Body Path of the Current Through the Body

  11. What really are the hazards? Arc Flash – Rapid release of energy due to an electrical fault. Incident Energy measured in cal/cm2 Typically caused by • Equipment Failure • Human Error

  12. What are the requirements around electrical safety? • What really are the hazards? • How do we protect employees? • What needs done to actually implement this program?

  13. How do we protect employees? Processes Equipment Design Tools Protective Equipment PPE

  14. How do we protect employees? Electrical Safety Program Elements Electrical Safety Program Qualifications Hazards Reliability Assessment Job Planning

  15. How do we protect employees? Qualifications NFPA 70E States: • A qualified person shall be trained and knowledgeable in the construction and operation of equipment…and be trained to identify and avoid the electrical hazards

  16. How do we protect employees? Qualifications Task Qualified: • A person can be considered Qualified to perform certain tasks while still being considered Unqualified with respect to other tasks

  17. How do we protect employees? Assessment Assess the hazards of the equipment and perform a risk assessment on those hazards • Likelihood of occurrence • Severity of event • Power Systems Study • Arc Flash Study • Short Circuit Study • Coordination Study

  18. How do we protect employees? Hazards Determine equipment needed to protect from hazards PPE Insulated Tools Test Equipment Barriers

  19. How do we protect employees? Hazards Approach Boundaries • Limited Approach Boundary • Restricted Approach Boundary • Arc Flash Boundary

  20. How do we protect employees? Job Planning Documenting the tasks being performed and identify the hazards associated with those tasks before any work begins. NFPA 70E list: Job Safety Plan Energized Electrical Work Permit

  21. How do we protect employees? Reliability Ensure the electrical equipment does not degrade over time to create additional hazards. • Maintained according to industry standards • NFPA 70B • NETA MTS

  22. What are the requirements around electrical safety? • What really are the hazards? • How do we protect employees? • What needs done to actually implement this program?

  23. What needs done to actually implement this program? Commitment Support from Leadership to develop the program

  24. What needs done to actually implement this program? Commitment Develop an overall plan for the Electrical Safety Program • Implementation • Resources • Costs

  25. What needs done to actually implement this program? Culture Change A Shift in the Electrical Safety Culture will Occur Must connect with people on plant floor Be prepared for questions

  26. What needs done to actually implement this program? Communication How does information flow through the organization?

  27. What needs done to actually implement this program? Communication Communicate to different Levels of an Organization • Maintenance Technician • What do I need to do to do my job?

  28. What needs done to actually implement this program? Communication Communicate to different Levels of an Organization • Maintenance Technician • Plant Manager • Never going to open a piece of electrical equipment • What is a Power Systems Study? • How does this effect the Plant?

  29. What needs done to actually implement this program? Communication Communicate to different Levels of an Organization • Maintenance Technician • Plant Manager • Corporate Role • How does program effect plant operations and scheduling?

  30. What needs done to actually implement this program? Continuity Electrical Hazards should follow the same requirements Facility 1 Facility 2

  31. What needs done to actually implement this program? Continuity Effective Communication Standardize Terminology Training

  32. Conclusion • Understand the hazards and requirements • OSHA 29 CFR 1910.301-.399 • NFPA 70E • Develop a Communication Plan • Consider how to communicate to different levels of an organization • Change in the electrical safety culture will take time • Communicate the “Why” behind the requirements

  33. Conclusion The Electrical Safety Program is in place to expand the understanding of electrical safety across an organization and drive improvement furthering the culture of electrical safety.
