COURSE OVERVIEW:

In environments where explosive gases, vapors, or dust are present, the management of electrical equipment requires a specialized technical approach to prevent ignition. This course provides a comprehensive framework for the "Operation and Maintenance" of Ex-certified equipment, focusing on the preservation of protection concepts such as Flameproof (Ex d), Increased Safety (Ex e), and Intrinsic Safety (Ex i). Participants will explore the mechanics of "Explosion Protection," learning how to conduct inspections that ensure the integrity of the equipment's "Type of Protection" is never compromised during its lifecycle.

The scope of this training addresses the full spectrum of hazardous area classifications (Zones 0, 1, and 2), focusing on the selection and installation of certified components. It covers the technical nuances of "Flamepath" maintenance, focusing on the measurement of "Gap Clearances" and the use of specialized non-setting greases to prevent corrosion. The curriculum provides a detailed focus on "Inspection Grades" (Visual, Close, and Detailed), ensuring that participants can identify "Unauthorized Modifications" or "Degraded Seals" that render an installation unsafe.

Coverage includes the implementation of international standards such as IEC 60079 for the repair, overhaul, and reclamation of Ex equipment. Attendees will learn to manage "Cable Gland" integrity, utilize "Intrinsic Safety" barriers correctly, and perform "Equipotential Bonding" in explosive atmospheres. By combining rigorous regulatory compliance with practical maintenance workflows, the course equips professionals with the expertise required to operate electrical systems in high-risk industrial environments with absolute safety and technical confidence.

COURSE OBJECTIVES:

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

• Define the "Area Classification" system (Zones, Gas Groups, and T-Classes).
• Identify the "Protection Concepts" (Ex d, Ex e, Ex n, Ex i, Ex p).
• Interpret "Ex Equipment Nameplates" and certification marks (ATEX/IECEx).
• Execute "Detailed Inspections" of flameproof enclosures and flamepaths.
• Perform "Cable Gland" selection and installation for hazardous areas.
• Implement "Maintenance Procedures" that preserve the Ex-rating.
• Utilize "Intrinsic Safety" (IS) parameters for loop verification.
• Conduct "Equipotential Bonding" and "Earthing" for static control.
• Identify "Unauthorized Modifications" and their impact on safety.
• Manage "Ex Repair and Overhaul" according to IEC 60079-19.
• Utilize "Non-Sparking" tools and safe work procedures in Zone 1/2.
• Document "Hazardous Area Inspection Reports" and Ex-Registers.

TARGET AUDIENCE:

This course is intended for Electrical Maintenance Engineers, Ex-Inspectors, Project Managers, and Technicians working in Oil and Gas, Petrochemical, or Mining industries.

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.
