HA Design

Who is this course for:

This course is our “engineering level” course, intended for electrical and instrumentation designers working in hazardous area industries.  It focusses on equipment selection and installation design and documentation, including intrinsically safe system verification and maximum power dissipation calculations for increased safety installations.

Entry Requirements:

Candidates for this course must be able to demonstrate existing electrical or instrumentation design competency.  This is best done by providing a CV and examples of design documents (e.g electrical drawings, schedules, specifications etc.) that the candidate has produced.  An electrical engineering degree or diploma is required.

Duration and delivery:

The course is 5-days duration.  We can run a program on site for 6 or more people.

The course is also available online, via a combination of instructor led and self-paced sessions. Click here for more details.

AS/NZS 4761.1:2018 Competencies:

Clause No. Unit Title

What happened to the UEE Units of Competency?

With the introduction of the new Electrotechnology Training Package Release 2 in October 2020, the older UEE units of competency for design in hazardous areas have been deleted and have not been replaced with any equivalent units of competency. Extend Training, in partnership with Response Consulting, will now be offering hazardous area design training based on AS/NZS 4761.1:2018 “Competencies for working with electrical equipment for hazardous areas (EEHA)”. Participants receive a Certificate of Training and Assessment upon successful completion of the course.
