The Updated NFPA 70E Standard: Bridging the Gap Between Compliance and Electrical Safety
- "Electric Shock" Emphasis: The term "electric shock" now consistently comes before "shock." This makes it clear when the standard refers to the dangerous effects of electrical current on the body. However, in specific references to "hearing protection boundary" and "lung protection boundary," "shock" means a shock wave (like from an explosion), not an electrical shock. This significant terminological clarification prevents ambiguity.
- Ambiguous Terms such as Flexible "Protectors": Terms that have been replaced, updated or superseded. For example, The term "leather" has been removed from the description of "protectors" (gloves and mittens worn over rubber-insulating gloves). This change allows for newer, potentially more effective materials, keeping safety gear in line with technological advancements.
- Article Scopes: Each article now includes a concise scope statement at the beginning. This gives a clear overview of the article's content, making it easier for readers to find the necessary safety information. For example, Article 110 focuses on establishing an electrically safe work condition, emphasizing the need for a comprehensive safety policy that prioritizes hazard elimination.
- Lockout/tagout: Check for current/voltage at every work point versus a single point to establish an electrically safe work condition.
Clear and consistent language is crucial in safety standards. By refining terms and definitions, the NFPA 70E 2024 aims to reduce confusion and ensure everyone involved in electrical work understands the safety requirements, and has the power and responsibility to take safety-supportive action.
