Developing an electrical safety program

I’m creating a training program for my electrical workers. What do you recommend as best practices to keep them safe from arc flash incidents and other electrical hazards?


Responding is Eduardo Torices, lead applications engineer, MELTRIC Corp., Franklin, WI.

Every organization should create an electrical safety program that not only mitigates the hazards, but also provides the recommended best practices for working on and around electrical hazards. The safety program should use the National Fire Protection Association 70E standard for electrical safety in the workplace to create solid electrical safety work and training best practices, as well as procedures to enhance worker safety. In fact, OSHA views the NFPA 70E standard as the primary consensus standard addressing electrical hazards associated with electrical utilization systems. OSHA also uses the 70E standard to support citations for certain violations.


Key elements

Electrical safety starts with the overall culture of the organization. Ideally, an electrical safety program would be championed by the organization’s environmental, health and safety professional, with support from C-suite executives, managers and supervisors. Employee buy-in and participation works best when the entire organization supports a true culture of safety.

A key piece of the training program should focus on implementation of the NFPA 70E Hierarchy of Controls to mitigate electrical hazards. The hierarchy places priority on eliminating electrical hazards before electrical work begins. Elimination is accomplished by disconnecting the electrical equipment from all possible sources of energy and releasing any stored electrical or mechanical energy. Employees should confirm the equipment is deenergized by properly interrupting the load, visually verifying the disconnection of the circuit and using appropriate testing equipment to ensure deenergization.

When hazards cannot be eliminated, an effort should be made to substitute them for lesser ones. Employees working with these hazards should be properly trained on how to work around the hazards. This training should familiarize employees with all possible sources of energy and the organization’s lockout/tagout policy.

When it becomes absolutely necessary to perform work on these hazards, the organization should provide employees with proper tools, training and personal protective equipment. These tools and PPE need to be rated for the hazard. The employees need to perform regular maintenance on the tools and PPE; should anything become damaged, it should be replaced. PPE is selected based on the available incident energy, which is calculated based on the facility’s electrical installation. In cases in which all the information isn’t available, tables and examples of how to determine or calculate incident energy are available in the 70E standard.

The available incident energy will help establish arc flash protection boundaries. These boundaries protect employees from unknowingly working near or walking through the general vicinity where electrical hazards exist. Arc flash boundaries prohibit unauthorized employees from accessing dangerous areas.

The 70E standard also requires employers to document and implement an electrical safety program that directs employee activities in a manner appropriate for different voltages, energy levels and circuit conditions that may be encountered in the workplace.

The best practices outlined in this response should be viewed only as a starting point for creating a comprehensive electrical safety program. Consult the 70E standard at for full details and recommendations.
