What concept was included in the 1995 edition of NFPA 70E?

The inclusion of Limits of Approach in the 1995 edition of NFPA 70E was significant because it addressed the safe distances that workers must maintain from exposed energized electrical conductors and parts. This concept is a fundamental aspect of arc flash safety and overall electrical hazard risk management. By establishing Limits of Approach, the standard provided clear guidelines to protect workers from the dangers of electric shock and arc flash events.

Understanding these limits is essential for implementing effective safety measures, particularly in environments where employees might work near or interact with energized electrical equipment. The introduction of this concept helped to formalize approaches to electrical safety in the workplace, ultimately reinforcing the importance of planning and risk assessment in electrical tasks.

In contrast, while grounding techniques, electrical wiring codes, and inspection procedures are all important facets of electrical safety, they were either already established in previous editions or addressed in different regulatory frameworks. Therefore, the standout feature of the 1995 edition was indeed the introduction of the Limits of Approach as a way to enhance worker safety standards.
