This module provides the foundation knowledge required for personnel entering hazardous area environments. It introduces the basic principles surrounding explosive atmospheres, ignition sources and why specialised equipment and procedures are required.

Delegates develop an understanding of how explosive atmospheres form, what conditions are needed for ignition and how hazardous area risks are controlled in industrial environments. Rather than focusing on technical installation requirements, this module establishes the underlying knowledge required before progressing into advanced competency areas.

Key learning areas:
• Explosive atmosphere fundamentals
• Ignition triangle concepts
• Hazardous area terminology
• Basic Ex equipment concepts
• Safe working practices

Typical roles:
Operations personnel, supervisors, project teams and personnel new to hazardous areas.

Ex000 is a theoretical module and can be delivered at the Source IEx facility or at customer premises.

This module develops a practical understanding of the methods used to prevent ignition within hazardous areas. Delegates learn why different protection concepts exist and how equipment is designed to safely operate where explosive atmospheres may be present.

Personnel develop understanding of Ex markings, temperature classifications, gas groups and equipment protection principles which support safe selection and use of equipment.

Key learning areas:
• Ex protection techniques
• Equipment markings
• Temperature classes
• Equipment Protection Levels
• Gas groups

Typical roles:
Electricians, engineers, maintenance technicians and hazardous area personnel.

This module focuses on determining where explosive atmospheres may occur and how hazardous zones are established. Classification activities play a major role in ensuring equipment is selected correctly and risks are managed appropriately.

Personnel learn how process conditions, releases, ventilation and environmental conditions influence hazardous area classification and how these decisions affect plant design.

Key learning areas:
• Zone classification
• Grades of release
• Ventilation considerations
• Documentation requirements
• Risk assessment principles

Typical roles:
Project engineers, design engineers and responsible persons.

This module is designed for personnel carrying out installation activities on hazardous area equipment and wiring systems. Correct installation is essential because small errors can compromise equipment protection methods and create safety risks.

Delegates learn installation practices, equipment selection requirements and installation methods used for Ex equipment and associated wiring systems.

Key learning areas:
• Equipment selection
• Cable and gland installation
• Wiring systems
• Terminations
• Installation documentation

Typical roles:
Electricians, installation technicians and commissioning personnel.

This module develops competence in maintaining equipment located within hazardous areas while preserving integrity and compliance. Personnel learn how maintenance activities can affect explosion protection methods and how defects should be identified and addressed.

Key learning areas:
• Maintenance principles
• Equipment integrity
• Defect identification
• Maintenance planning
• Documentation

Typical roles:
Maintenance technicians and engineers.

This module develops the knowledge and competence required to conduct visual and close inspections of hazardous area equipment and installations.

Personnel learn how to identify common defects, incorrect installations and physical damage which could affect safety and compliance.

Key learning areas:
• Inspection types
• Identifying defects
• Documentation
• Reporting requirements

Typical roles:
Inspectors and maintenance personnel.

This module builds on inspection requirements and introduces detailed inspection and auditing techniques used for hazardous area installations.

Personnel learn how to conduct thorough compliance reviews and identify issues affecting operational safety.

Key learning areas:
• Detailed inspections
• Compliance reviews
• Audit techniques
• Reporting

Typical roles:
Inspectors, auditors and responsible persons.

This module focuses on the design requirements associated with electrical systems operating within hazardous areas. Delegates develop understanding of design principles, equipment selection and documentation requirements.

Key learning areas:
• Equipment selection
• Design principles
• Standards application
• Documentation

Typical roles:
Design engineers and project engineers.

Ex009 is a theory-based design module and can be delivered at the Source IEx facility or at customer premises.
