This Hazardous Areas Classification and Design course provides nationally recognised training that meets the competency requirements of AS/NZS 4761 Competencies for working with electrical equipment for hazardous areas (EEHA).
The course content covers Hazardous Area Classification procedures and techniques as well as planning and design considerations for electrical installations in explosive atmospheres.
Delivered at one of Competency Training’s national training centres, or at a client’s facility.
The Hazardous Areas Classification and Design course covers the following topics:
- Legal requirements and Australian Standards
- Properties of explosive gases and vapours
- Properties of combustible dusts
- Hazardous area classification procedures and techniques, including the gathering and analysis of data relevant to the explosive hazard
- Determination of the extent of the risk
- Documentation of the hazardous areas zones
- Equipment selection
- General installation requirements
- Electrical protection
- Record keeping – the Verification Dossier
- 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)

WHO SHOULD ATTEND?
This is an advanced course, intended for electrical workers, technicians, engineers and senior engineers involved in the classification of potentially explosive atmospheres and the planning and design of electrical systems and installations in or associated with hazardous areas.
HAZARDOUS AREAS CLASSIFICATION
Competency Training’s Hazardous Areas Classification course makes up the first three days of this Hazardous Areas Classification and Design course. Students who will not be involved in the planning and design of the installation may opt to attend only the Classification section of the course.
CONDUCT A CONFORMITY ASSESSMENT
During the process of designing an electrical installation for a hazardous area, there may be times when it is impossible to get a locally certified piece of equipment. In this situation, the designer must obtain a Conformity Assessment Document for the equipment.
Competency Training’s Conduct a Conformity Assessment course is completed by Recognition of Prior Learning. It is expected that students will be able to provide evidence of having previously completed the Conformity Assessment process.
