Personal Protective Equipment (PPE) presented in this app is based on the task tables from NFPA-70E 2012, NEC and IEEE Refereed Articles. For Tri-Services (US Army Corps of Engineers, Navy-Marines & Air Force) facilities electrical (VAC) work, consult your AHJ to determine if the principal reference for shock and arc flash boundary analysis is the UFC 3-560-01 dated May 2012.
Begin by selecting a source of energy from the list below. You will then be prompted to enter more information about the electrical system.
The sources below are not covered by this application. Refer any questions to your organization’s Electrical Safety Subject Matter Expert.
This application was developed by the US Army Research Laboratory and DoD's Defense Safety Oversight Council Electrical Safety Working Group.
The application is intended to be utilized by TRAINED and QUALIFIED personnel who must design, repair or install potentially hazardous electrical equipment in the performance of their duties. It is not intended as a stand-alone electrical safety guide, rather as a single part in larger overall system safety analysis. Additional training may be required as deemed adequate by supervisory staff.
As determined by your Command's Electrical Safety Office, training may include:
Information presented is organized using the Electrical Hazard Classification Tool, 2012 edition. The Tool is a graphic representation of electrical hazards as determined by possible injury, and provides the recommended controls for mitigation of the hazard for the various Modes of Work on Electrical Equipment. This classification tool is not to be confused with the hazard risk categories for personal protective equipment defined in NFPA 70E. Work Controls are based on, as applicable, the NFPA-70E Standard for Electrical Safety in the Workplace, 2012 edition, and PPE is taken from the NFPA task table 130.7.
E-Safe Pro assumes that equipment has been properly maintained and used as intended.
All calculations and recommendations must be reviewed and approved by your organization’s Electrical Safety Subject Matter Expert.
The boundary definitions used by E-Safe Pro are depicted in the image below:
Shock and arc flash boundary analysis shall be completed before a person approaches nearer than a safe distance from an electrical hazard.
Specialized system knowledge and methods may be necessary to calculate the shock and arc flash boundaries for some non-typical electrical equipment found in the workplace, such as DC or capacitor systems, as methods are not available in existing codes and standards.
