    Phase I: Engineering Assessment

    Site Assessment (Data Gathering)

    • Develop Single Line Diagrams
    • Transformer Data (KVA, Voltages, Impedance)
    • Conductor Sizes and Lengths
    • Relay, Fuse and Circuit Breaker Information
    • Electric Utility – Available Fault Current
    • Info needed to complete an Arc Flash Study

    Short-Circuit Analysis

    • Determines maximum fault currents
    • Required for Protective Device Coordination Study
    • Required for Arc Flash Study
    • Required for Interrupting Rating Analysis

    Protection Device Coordination Study

    • Determines proper circuit breakers and fuses clear each fault on system
    • Determines “Clearing Time” for arc fault currents required for Arc Flash Analysis

    Interrupting Rating Analysis

    • Determine if protective devices have adequate interrupting capacity for the available short-circuit current

    Arc-Flash Hazard Analysis

    • Calculate Incident Energy
    • Determine Hazard/Risk Category
    • Specify PPE Requirements

    Recommend Solutions to Problems

    • Breaker Coordination Problems
    • Inadequate Interrupting Ratings
    • Potentially Dangerous Arc Flash Energy
    • Opportunities to Reduce Hazard/Risk Category Level

    Phase II: OSHA Required Documentation

    Electrical Safety Program

    • Determine Policies on Electrically Safe Work Conditions
    • Develop an Electrically Energized Work Permit
    • Determine who can reset Circuit Breakers
    • Establish PPE Requirements Inside Approach Boundaries
    • Determine PPE Clothing Policy

    Procure Appropriate PPE

    • Flame-Resistant Clothing Based on Hazard/Risk categories
    • Voltage Rated Gloves
    • Voltage Rated Tools

    Warning Labels

    Phase III: Training Workforce


    • Provide training for Qualified Employees on hazard recognition and electrical safe work practices
    • Provide real world examples
    • Provide training for all unqualified employees, supervisors, and safety personnel on understanding the hazards
