COURSE OVERVIEW:

An arc flash is one of the most dangerous events in an electrical system, capable of releasing massive amounts of thermal energy, pressure waves, and toxic gases. This course provides a comprehensive engineering and safety framework for performing arc flash hazard analysis and implementing effective mitigation strategies. Participants will explore the physics of the electric arc, the factors that determine incident energy levels, and the rigorous mathematical models—such as IEEE 1584—used to quantify risk in industrial and utility environments.

The scope of this training addresses the technical requirements for conducting a facility-wide arc flash study, including data collection, system modeling, and the calculation of flash protection boundaries. It focuses on the intersection of electrical protection and personnel safety, examining how relay settings and fuse characteristics directly influence the severity of an arc event. The curriculum provides a deep dive into the regulatory landscape, ensuring compliance with international standards such as NFPA 70E, while emphasizing the practical application of the hierarchy of controls to reduce risk.

Coverage includes the selection and maintenance of Personal Protective Equipment (PPE), the design of arc-resistant switchgear, and the implementation of advanced technologies such as light-detecting relays and virtual main systems. Attendees will learn how to interpret arc flash labels and develop safe work practices for energized electrical work. By combining rigorous analytical methods with practical safety leadership, the course ensures that organizations can protect their workforce, minimize equipment damage, and maintain a culture of electrical safety excellence.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Describe the physics and causes of arc flash and arc blast events.

TARGET AUDIENCE:

This course is intended for Electrical Safety Officers, Facility Engineers, Design Engineers, Maintenance Managers, and EHS Professionals responsible for electrical safety and compliance.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
