ARC Flash & Electrical Safety


Inadequate electrical installation often resulted in fires. In recent years, the community has begun to recognize that in addition to fire and electrocution, arc-flash and arc-blast hazards also result in injury. The knowledge base about these hazards is expanding but is not yet complete. The community knows that as the distance between an employee and an electrical hazard decreases the degree of exposure increases. Employees must understand that they are exposed to these hazards until an electrically safe work condition has been established.

The ARC Flash & Electrical Safety training course provides front-line electrical workers with the information they need to make safe decisions involving their work practices. From this training, they will receive the proper awareness and training needed in order to develop a personal arc flash safety strategy in the workplace.

The key features of the ARC Flash & Electrical Safety training course are:

  • List OSHA electrical safety requirements and design standards 
  • Explain the NFPA 70E for Electrical Safety Requirements 
  • Identify electrical work practices and maintenance requirements 
Learning Objectives

Upon attendance to the ARC Flash & Electrical Safety training course, participants will learn how to:

  • Identify electrical safety training requirements for qualified workers
  • Identify best practice Regulations that address shock and arc flash hazards
  • List the steps to perform a shock hazard analysis and describe each step
  • List the personal protective equipment required for shock protection
  • List the steps to achieve an electrically safe work condition
  • List the steps to install and remove temporary protective grounding equipment
  • Explain what an arc flash is and the injuries that can result
  • Identify when an arc flash hazard exists
  • List the steps to perform an arc flash hazard analysis and describe each step
  • Define the term “incident energy,” identify the key electrical system variables that affect it
  • Define the term “arc flash protection boundary” and explain its application
  • Define the term “arc-rated” and explain the difference between “flame-resistant” clothing and “arc rated” clothing
  • Select appropriate personal protective equipment for arc flash hazards
  • Describe the Hazard/Risk Category method of selecting arc flash PPE
  • List the testing and maintenance requirements for personal protective equipment
  • Identify the key objectives of job safety planning
Target Audience

The ARC Flash & Electrical Safety training course is suitable for all employees, who may reasonably be expected to face risk of injury due to electric shock or other electrical hazards, that typically include:

  • Supervisors
  • Electrical and electronic engineers
  • Electrical and electronic equipment assemblers
  • Electrical and electronic technicians
  • Electricians
  • Industrial machine operators
  • Material handling equipment operators
  • Mechanics and repairers
  • Painters
  • Riggers and roustabouts
  • Stationary engineers
  • Welders
Training Methodology

The ARC Flash & Electrical Safety training course uses a range of approaches to learning, including experiential group activities, individual exercises, mini-case studies, role plays and syndicate discussions. Formal inputs are used to introduce underpinning theory. A key part of the learning process is sharing the differing experiences participants bring, as well as experimenting with novel – and sometimes challenging – techniques.
