This course provides a licensed electrical worker with the specialised skills and knowledge required to perform installation, maintenance, testing and inspection of electrical equipment in explosive atmospheres.

The Installation and Maintenance of Electrical Equipment in Hazardous Areas course covers the following topics in detail:

• Equipment installation requirements
• Legal requirements and Australian Standards
• Principles of hazardous areas classification
• Procedures for breakdowns and maintenance
• Testing procedures
• Visual inspection
• Detailed inspection
• Record keeping
• Access and permit procedures for use in hazardous areas
• Explosion-protection techniques, including:
• Dust protection by enclosure (Ex tD)
• Flameproof (Ex d)
• Increased Safety (Ex e)
• Intrinsic Safety (Ex i)
• Pressurisation (Ex p)
• Ventilation (Ex v)
• Encapsulation (Ex m)
• Non-Sparking (Ex n)
• Oil Immersion (Ex o)
• Powder Filling (Ex q)
• Special Protection (Ex s)
• Mixed Techniques

Practical activities are conducted on purpose-built training boards that simulate real hazardous area installations. Many products are supplied from leading international manufacturers such as; Pepperl+Fuchs, CCG Cable Glands, Weidmüller and Cuthbert Stewert Limited in New Zealand.
