EX05 to EX06 – Dust

Target Audience

This course is designed for Electricians, technicians, and engineers who work in hazardous areas where combustible dusts are present. Individuals seeking CompEX certification to demonstrate competency in the installation, inspection, and maintenance of electrical equipment in dust-explosive environments.

Course Overview

The CompEX EX05-06 Dust course provides practical and theoretical training focused on the safe use of electrical equipment in dust hazardous areas. The course follows the internationally recognised CompEX scheme and ensures delegates gain the necessary competence and confidence to work in environments where combustible dust presents an explosion risk.

Candidates will learn what considerations must be given to areas that contain potentially explosive or flammable atmospheres, and the factors used to classify their location.

The course includes instruction on how to read hazardous area certification, labelling and documentation relating to dust factors that need to be considered when managing dust clouds and layers. It also covers the main protection concepts, categories and levels that are applied to certified Ex electrical equipment.

Topics covered:

• Identify national regulations, directives, and IEC standards for hazardous dust areas
• Understand criteria and descriptors for classifying hazardous dust locations
• Recognize properties of hazardous dusts, fibres, and flyings (combustible, conductive, non-conductive)
• Understand certification, protection concepts, and handling of Ex electrical equipment (e.g., Ex i, d, e, m)
• Know test values for IS (Intrinsically Safe) and non-IS systems
• Use IEC inspection table 1 to inspect EX equipment
• Interpret documentation for Intrinsically Safe systems
• Use IEC inspection table 2 for certified, non-certified, simple, and associated IS equipment
• Identify and record inspection faults accurately
• Understand the importance of proving isolation before inspections
• Use correct and relevant documentation
