VLOG 4 – Competency Schemes

Hi there! Welcome back to Extend Training’s blog series on hazard areas. For this instalment we’re going to have a quick look at some of the other competency schemes that exist around the world for demonstrating competency for hazardous area electrical work. In Australia we are most familiar with ASNZS4761 and the UAE 11 training… Read more »

VLOG 3 – Barrier Glands

Hi there. A big welcome back to all the Haz Area masochists out there. I know you’re excited to hear our rant about compound barrier glands, so I’ll get right to it. In our experience there is a common misconception about the reasons for using barrier glands in an installation. Lots of people associate them… Read more »

VLOG 2 – Myth Busting Legislation Requirements

Hi there, and welcome to our follow up vlog on the difference between competency and licensing. As promised, we’ll be slaying the sacred cow that says a person must always hold an Australian electrical licence to work on hazardous area electrical equipment in this country. Let’s start by saying that we’re not complete nutters, and… Read more »


Hi and welcome to Extend Training’s video blog series on hazardous area issues. I can’t help but wonder sometimes if the inventors of the internet would have gone ahead with it if they knew what it would be used for, but here we are in 2017 and I don’t own a cat, so we’re reduced… Read more »


We’ve had a great response to our blog post, “Ex e Terminal Box Practicalities,” including some good questions that we thought it would be worth addressing in a follow up post. Steve, a senior electrical engineer working in refrigeration dropped us a line to ask about spare terminals. Steve writes: “I read your article regarding… Read more »


Standards drive a lot of the differences between onshore and offshore installations, but some things are simply down to preferences, or established industry practices. Some of the biggest noticeable differences with offshore installations are: 1. Cables – braided armour is more common, low-smoke, zero-halogen (LSZH) cables mandatory 2. Cable transits – Multi Cable Transits (MCTs)… Read more »


If you want to get into the offshore game, you will almost certainly need to hold a dual electrical/instrumentation trade. Accommodation is limited on offshore facilities so electrical personnel are expected to also handle instrumentation. You’ll need some maintenance experience in your CV too – not just construction. EEHA competencies covering installation, maintenance and inspection… Read more »


Onshore it is likely that AS/NZS 3000 will apply, often together with other industry-specific standards such as the AS/NZS 3007 series. Even if the legislation that applies allows some freedom for the facility owner to nominate different standards to control electrical risk, it is rare that that will do so. Australian electrical workers are familiar… Read more »

Onshore vs Offshore what you need to know: Legislation

The legislation covering the Australian offshore industry is a Commonwealth (federal) Act: The Offshore Petroleum and Greenhouse Gas Safety Act (OPGGSA). That means the law is the same whether you are in Bass Strait, the North West Shelf or anywhere else in Australian waters. The industry regulator is the National Offshore Petroleum Safety and Environmental… Read more »

MYTH 5: Refresher training is required every 2 years.

MYTH 5: Refresher training is required every 2 years. False! This may come as a surprise, but there is actually no specified interval requirement when it comes to ‘refresher training.’  Did you know that the AS/NZS/IEC 60079.14 only states that “appropriate continuing education or training shall be undertaken by personnel on a regular basis”? While… Read more »
