Elements of an electrical maintenance plan
Under NFPA 70B, plant teams are responsible for ensuring that these elements and processes are part of every EMP:
- Verify that all equipment and systems comply with applicable installation codes and standards by inspection.
- Consider the current condition of maintenance of electrical equipment and systems and the potential safety and operational risks to maintenance and operational personnel.
- Define EMP principles upon which the plan is based and goals to be achieved. It should be designed to function in conjunction with the applicable electrical safety program.
- Identify personnel responsible for implementing each element of the program.
- Survey and analyze electrical equipment and systems to determine maintenance requirements and priorities.
- Document maintenance procedures for equipment, including a plan for inspections, servicing and suitable test.
- Develop a records-retention policy for maintenance, equipment and personnel documentation.
- Outline a process to prescribe, implement and document corrective measures based on collected data.
- Develop a process for incorporating design for maintainability in electrical installation.
- Determine a program review and revision process that considers failures and finding for continuous improvement.
- Identify the controls by which it is measured and monitored.
- Develop a method to use feedback reports, such as electrical safety incidents, equipment malfunctions, unintended operation or alarms, and operation of protective devices, for EMP refinement.
Other EMP requirements:
- The plan should be audited at least every five years.
- The EMP should identify an EMP coordinator.
- Personnel assigned to EMP duties should be trained in the specific maintenance tasks, test methods, test equipment, PPE usage, and hazards associated with the electrical equipment of system being services.
- All training must be documented.
