COURSE OVERVIEW:

Electrical installations in areas where explosive atmospheres may occur represent one of the highest safety risks in the industrial sector. This course provides a technical framework for the complete lifecycle of electrical assets in hazardous zones, from initial area classification to decommissioning. Participants will explore the rigorous standards that govern the design and operation of these systems, focusing on how to prevent electrical energy from becoming an ignition source in the presence of flammable gases, vapors, or dusts.

The scope of this training addresses the international standards for area classification (Zones and Divisions) and the selection of appropriate protection concepts (Ex d, Ex e, Ex i, etc.). It covers the technical nuances of installing and maintaining certified equipment, emphasizing the importance of preserving the "Ex" integrity through correct glanding, sealing, and bonding. The curriculum provides a detailed focus on the management of safe operations, including permit-to-work systems and the use of specialized tools in high-risk environments.

Coverage includes the implementation of systematic inspection regimes to ensure long-term compliance with safety regulations. Attendees will learn to identify common installation errors and environmental degradation that can compromise explosion protection. By combining theoretical combustion science with practical engineering and maintenance protocols, the course equips professionals with the expertise required to manage hazardous area installations that meet the highest international safety and reliability standards.

COURSE OBJECTIVES:

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

• Classify hazardous areas into Zones 0, 1, and 2 according to IEC standards.
• Identify ignition sources: Sparks, hot surfaces, and static electricity.
• Differentiate between various "Ex" protection concepts and their applications.
• Select appropriate electrical equipment based on Gas Groups and T-classes.
• Interpret certification labels and equipment markings accurately.
• Execute professional installation of Ex d, Ex e, and Ex i equipment.
• Select and install specialized cable glands for hazardous zones.
• Implement effective grounding and bonding for static dissipation.
• Conduct "Visual," "Close," and "Detailed" inspections of Ex assets.
• Maintain the Hazardous Area Verification Dossier for compliance.
• Troubleshoot faults in hazardous areas using safe work practices.
• Ensure regulatory compliance during the repair and overhaul of Ex equipment.

TARGET AUDIENCE:

This course is intended for Electrical Engineers, Site Safety Officers, Maintenance Technicians, and Project Managers working in oil, gas, chemical, and industrial sectors.

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.
