COURSE OVERVIEW:

The purpose of this course is to provide specialized technical expertise in the design, installation, and maintenance of electrical and instrumentation systems within explosive atmospheres. In industries such as oil and gas, chemical processing, and mining, the presence of flammable gases or dusts creates a high-risk environment where a single electrical spark or hot surface could lead to a catastrophic explosion. This program focuses on the rigorous protection methods required to prevent ignition and ensure the safety of personnel and assets.

The scope of this training encompasses the international classification systems for hazardous areas, including the Zone (IEC) and Division (NEC) models. Participants will explore the diverse range of protection techniques, such as Flameproof (Ex d), Intrinsic Safety (Ex i), Increased Safety (Ex e), and Purged/Pressurized (Ex p) systems. The curriculum is designed to provide a deep understanding of how equipment is certified and the specific installation rules that must be followed to maintain the integrity of these safety ratings.

Coverage includes the practical aspects of cable entry systems, the use of certified glands, and the critical importance of grounding and bonding in hazardous zones. Attendees will learn how to perform detailed inspections, identify signs of enclosure degradation, and safely perform maintenance on live intrinsically safe circuits. By focusing on both regulatory compliance and field-level execution, the course ensures that participants can manage electrical infrastructures that meet the highest global safety standards for explosive environments.

COURSE OBJECTIVES:

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

• Analyze Hazardous Area Classification maps and Zone definitions.
• Differentiate between Gas (G) and Dust (D) explosive environments.
• Select appropriate Protection Methods (Ex d, Ex i, Ex e, Ex n, Ex p).
• Interpret Equipment Marking and Certification Labels (ATEX/IECEx).
• Execute the correct installation of Explosion-Proof (Ex d) enclosures and seals.
• Design and verify Intrinsically Safe (IS) loops using Zener Barriers.
• Implement correct grounding and bonding to prevent static discharge.
• Select and install certified Cable Glands and Sealing Compounds.
• Perform Visual, Close, and Detailed Inspections of Ex equipment.
• Troubleshoot electrical faults without compromising safety ratings.
• Manage the lifecycle of Ex equipment using an Inspection Register.
• Ensure compliance with IEC 60079 and local safety regulations.

TARGET AUDIENCE:

This course is intended for Electrical Engineers, Instrument Technicians, Site Safety Inspectors, and Maintenance Supervisors working in high-risk industrial facilities.

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.
