Arc Flash Hazard Analysis


Arc flash hazards should be looked upon seriously and with adequate safety measures, training and knowledge shall be in compliance with IEEE 1584 and NFPA 70E. Technology is also instrumental in preventing arc flash hazards. Electrical accident preventions are always in placed but accidents still take a toll on the persons working on the premises. Electricity is a familiar and necessary part of everyday life, but electricity can kill or severely injure people and cause damage to property.

There are simple precautions and personal protective equipment to be used when working with switchgears that can be taken to significantly reduce the risk of arc flashes. Arc flashes are to be contained and precautions are to be in placed against arc flashes accidents. Proper and correct personal protective equipment are mandatory as it can save lives and prevent severe injuries.

The training seminar will highlight:

  • Causes of arc flash
  • Types of faults and its effect
  • Arc flash incidents
  • Limits of approach
  • Technology in reducing arc flashes


At the end of the training seminar, you will learn to:

  • Understand the importance of arc flash accident prevention in medium and high voltage electrical installation
  • Explain the necessity of working safely
  • Learn the dangers and hazards of high voltage electrical faults
  • Determine how to avoid accidents at your workplace
  • Analyse the various methods of arc flash reduction devices

Training Methodology

Each training seminar participant will receive a copy of the comprehensive seminar notes. The presenter will outline and discuss the topics using computer displays, video clips and PowerPoint presentation. The training seminar is designed to have an interactive format to maximize delegate participation. Questions and answers are encouraged throughout and at the daily sessions. Needs-Based case-studies and examples will be discussed in problem solving workshop sessions.

Organisational Impact

Upon completion of the training seminar, the organisational impact would be:

  • Technical training and up-skilling to improve and realise the full potential of a competent workforce
  • Productivity increase through minimisation of project time acceptance/design and commissioning
  • Identification for opportunities of improvements due to deep understanding of the presented state-of-the-art technologies
  • Networking of personnel with technology leaders and other engineers and technicians with strong field experience
  • Exposure of personnel to the standard international procedures
  • Attitude change of workforce, as continuous follow up of new technologies and their up taking could otherwise create workforce with high resistance to change due to lack of understanding

Personal Impact

On successful completion of this training seminar delegates will be able to understand:

  • The importance of safety in high voltage installations
  • Understand the hazards of arc flash accidents
  • Identify the dangers and risks of accidents in a high voltage installation
  • Appreciate the importance of hazard warning labels
  • Be careful and aware of limits of approach
  • Recognize the effort of implementing arc flash hazard reduction devices

Who Should Attend?
