The future of electrical safety
NFPA 70E brings the hierarchy of controls to the forefront.
NFPA 70E annex documents
Revised and New Informative Annexes
Recent editions have been revised and new informational annexes have been added to support risk assessment and application of the hierarchy of controls. The 2018 edition includes these changes:
Annex F Risk Assessment and Risk Control
Simplification of the title from previous editions reflects a rewrite of this annex to simplify and focus the information to facilitate application. The annex is rewritten to more closely conform with ISO 31010 Risk management – Risk assessment techniques and ANSI Z10 Occupational Health and Safety Management Systems. For stakeholders wanting to learn more on the subject of risk assessment and control, the Risk Assessment Institute offers educational materials, many of which are accessible at no cost. Established by the American Society of Safety Engineers in 2013, the Risk Assessment Institute serves as a center of excellence for risk-related information and tools relevant to the occupational safety and health profession. More than 20 free online video lectures and other resources are available by visiting www.oshrisk.org.
Annex K General Categories of Electrical Hazards
This annex is rewritten to include up-to-date statistics and sources for data on injuries and fatalities from contact with or exposure to electrical energy. Current and credible injury data is helpful in justifying requirements for risk assessment and application of hierarchy of controls.
Annex O Safety Related Design Requirements
Engineering design options that provide inherently safer facilities and installations are added to support application of higher order control measures of Substitution and Engineering Controls.
Annex P Aligning Implementation of This Standard with Occupational Health and Safety Management Standards
This annex first appeared in the 2012 edition. It supports reference to ANSI Z10 Standard for Occupational Health and Safety Management Systems in Article 110.1(A) Informational Note 2.
Annex Q Human Performance and Workplace Electrical Safety
This is a new annex that will help stakeholders better understand vulnerability to human error, value higher order controls that reduce dependence on error-free performance, and provide insight in addressing organizational deficiencies that lead to human error. The annex conveys information on human performance that evolved from efforts in nuclear energy industries aimed at identifying and mitigating causes of human error with potential catastrophic consequences. To learn more on this topic, the U.S. Department of Energy has a 175-page publication available for free download from its website. Search “DoE Human Performance Handbook.”
