IEEE 80 aims to establish safe working practices around energized electrical equipment, including substations, switchyards, and other high-voltage environments. It provides detailed procedures for:
- Establishing safety boundaries
- Performing safe work on energized equipment
- Implementing protective measures
- Conducting electrical hazard assessments
The scope covers both design considerations and operational safety procedures applicable to electrical power systems operating at various voltage levels, from low voltage to extra-high voltage.
Key Objectives of IEEE 80
- Minimize risk of electrical shock and arc flash incidents
- Provide guidelines for safe work procedures
- Standardize safety practices across different organizations
- Promote hazard awareness and risk mitigation
- Ensure compliance with federal and local safety regulations

Core Components of IEEE 80
1. Safety Boundaries and Zones
IEEE 80 emphasizes the importance of defining safety boundaries around energized equipment:
- Limited Approach Boundary: The minimum distance personnel must maintain from energized parts without personal protective equipment (PPE).
- Restricted Approach Boundary: The distance where only qualified personnel with PPE can work or approach.
- Arc Flash Boundary: The distance at which an arc flash could cause a second-degree burn, requiring PPE.
Establishing these boundaries helps prevent accidental contact with live parts and reduces electrical shock hazards.
2. Electrical Hazard Assessment
A crucial part of IEEE 80 involves assessing electrical hazards to identify potential risks. This includes:
- Evaluating system voltage levels
- Analyzing fault currents
- Determining arc flash energy levels
- Assessing human error probabilities
Proper hazard assessments inform safety procedures, PPE requirements, and training programs.
3. Personal Protective Equipment (PPE)
IEEE 80 specifies the types of PPE necessary based on hazard assessments, including:
- Flame-resistant clothing
- Insulating gloves and sleeves
- Arc-rated face shields and hoods
- Insulated tools
Proper PPE selection and usage are vital for protecting personnel from electrical shocks and arc flash burns.
4. Safe Work Practices and Procedures
The standard provides detailed procedures for performing work on energized equipment, such as:
- Establishing an electrically safe work condition
- Lockout/tagout procedures
- Use of barriers and signage
- Verification of de-energization
It also emphasizes qualified personnel performing tasks, with appropriate training and awareness.
5. Arc Flash Analysis and Management
IEEE 80 integrates with IEEE 1584, which provides methods for calculating arc flash incident energy. This analysis helps determine:
- PPE requirements
- Safe working distances
- Engineering controls
Implementing arc flash mitigation strategies reduces incident severity and enhances safety.
