COURSE OVERVIEW:

In industrial environments where flammable gases, vapors, or dusts are present, the selection and application of electrical and instrumentation equipment are critical to preventing catastrophic ignitions. This course provides an advanced examination of the engineering principles required to operate safely in hazardous atmospheres, focusing on the various protection concepts defined by international standards. Participants will explore the science of ignition sources such as sparks, hot surfaces, and static electricity—learning how to mitigate these risks through specialized equipment design.

The scope of this training addresses the rigorous classification of hazardous zones (Zone 0, 1, and 2) and the corresponding requirements for equipment certification (Ex d, Ex e, Ex i, etc.). It covers the technical nuances of selecting instruments and electrical assets that are suitable for specific gas groups and temperature classes. The curriculum provides a detailed focus on the design and installation of intrinsically safe systems and flameproof enclosures, providing a framework for creating a coordinated safety strategy that complies with ATEX and IECEx regulations.

Coverage includes the practical implementation of inspection and maintenance protocols for equipment installed in explosive atmospheres. Attendees will learn to conduct "Initial," "Periodic," and "Sample" inspections to ensure that the integrity of the protection concept is maintained throughout the equipment's lifecycle. By combining theoretical knowledge of combustion physics with practical selection and maintenance strategies, the course equips professionals with the expertise required to manage electrical and instrumentation assets in the world’s most demanding industrial environments.

COURSE OBJECTIVES:

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

• Define and classify hazardous zones based on the frequency of flammable risk.
• Identify ignition sources and their mitigation in electrical systems.
• Differentiate between Ex d, Ex e, Ex i, Ex n, and Ex p protection concepts.
• Select appropriate equipment based on Gas Groups and Temperature Classes.
• Design and verify Intrinsically Safe (IS) loops and barrier installations.
• Interpret equipment marking and certification labels professionally.
• Implement proper cable entry and glanding techniques for Ex enclosures.
• Conduct detailed inspections according to IEC 60079-17 standards.
• Maintain the integrity of flameproof gaps and weatherproofing seals.
• Troubleshoot faults in hazardous area equipment without compromising safety.
• Implement grounding and bonding for static electricity dissipation.
• Manage the documentation required for a Hazardous Area Verification Dossier.

TARGET AUDIENCE:

This course is intended for Electrical and Instrumentation Engineers, Safety Officers, Maintenance Technicians, and Inspectors working in oil, gas, chemical, and pharmaceutical 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.
