Auditing a mission-critical facility’s NFPA 70E performance ensures compliance with electrical safety standards and protects personnel from electrical hazards. Here’s a step-by-step approach to perform a thorough audit: 1. Define the Scope of the Audit Clearly identify what aspects of NFPA 70E compliance will be evaluated, such as: Electrical Safety Program Training of personnel Maintenance of electrical equipment Use of proper PPE (Personal Protective Equipment) Documentation and incident reporting 2. Review Electrical Safety Program (ESP) Ensure the facility has a written Electrical Safety Program that aligns with NFPA 70E requirements. Verify that the ESP includes procedures for: Lockout/Tagout (LOTO) Energized work permits Arc flash risk assessments Electrical hazard incident reporting 3. Perform Training and Awareness Assessment Verify Training Records : Ensure all qualified and unqualified workers receive training on NFPA 70E standards. Skills Testing : Confirm that workers understand arc flash boundaries, shock protection, and safe work practices. Refresher Courses : Review the frequency of retraining (typically every 3 years or upon significant job changes). 4. Audit PPE Compliance Ensure workers are equipped with proper arc-rated PPE based on the calculated incident energy levels for tasks. Evaluate: PPE inspection, testing, and maintenance logs Availability and condition of PPE, including gloves, face shields, and arc-rated clothing Worker adherence to wearing appropriate PPE during tasks 5. Review Arc Flash and Shock Hazard Analysis Verify that the facility has conducted Arc Flash Risk Assessments as required by NFPA 70E. Review labels on equipment to ensure they display accurate: Arc flash boundary distances Incident energy levels Required PPE categories Confirm updates are performed within the recommended 5-year cycle or when system changes occur. 6. Inspect Electrical Equipment Maintenance Records Audit the maintenance schedules for electrical systems, ensuring they follow NFPA 70E and NFPA 70B guidelines. Evaluate records of: Circuit breakers, switchgear, and relays maintenance Infrared thermography inspections Ground fault protection systems Test results for insulation resistance 7. Evaluate Energized Work Procedures Confirm proper use of Energized Electrical Work Permits (EEWP) . Review procedures for: Justification for energized work (e.g., infeasibility to de-energize) Risk assessments performed before work Authorization and approval processes 8. Examine Incident and Near-Miss Reporting Review records of electrical safety incidents and near misses. Verify root cause analyses were performed and corrective actions were implemented. 9. Conduct Field Observations Perform spot checks during work activities to assess worker adherence to NFPA 70E standards. Look for compliance with: Establishing shock and arc flash boundaries Proper use of tools and PPE LOTO procedures 10. Audit Documentation and Recordkeeping Ensure that all safety assessments, training records, PPE inspections, and incident reports are properly documented and stored. Verify accessibility for regulatory audits or internal reviews. 11. Report Findings and Recommend Improvements Generate a detailed report summarizing: Areas of non-compliance or gaps Observations from field audits Recommendations for corrective actions A timeline for implementation Rank findings by risk level to prioritize actions. 12. Continuous Improvement and Follow-Up Establish a regular schedule for NFPA 70E performance audits (e.g., annually). Monitor the completion of corrective actions and verify improvements over time. Tools to Assist the Audit Software : Use audit tools or CMMS (Computerized Maintenance Management Systems) to track electrical maintenance schedules and PPE inspections. Compliance Checklists : Develop or use NFPA 70E checklists for consistency in audits. Field Testing Tools : Utilize thermal imaging and electrical test equipment to validate system performance. By following this structured approach, a mission-critical facility can effectively audit its NFPA 70E performance and ensure worker safety, regulatory compliance, and operational continuity.
