CompEx Training Humber — Refinery and Chemical Electricians

EX Academy Knowledge Base · IEC 60079 · CompEx Preparation · 2025

If you're an electrician or instrument technician based in the Humber preparing for your CompEx assessment, EX Academy's online platform gives you full access to preparation materials from anywhere — no travel, no fixed course dates, no rigid schedule.

Why the Humber Has High CompEx Demand

The Humber estuary is home to several major refineries and chemical plants including the Phillips 66 Humber Refinery at South Killingholme, the Prax refinery at Lindsey, and multiple chemical processing facilities. The Immingham and Grimsby area is a major centre for UK downstream oil and gas. Electricians in this area typically require CompEx Ex01/Ex03, with Ex02/Ex04 for IIC areas in hydrogen handling and certain chemical processes.

Which CompEx Units Do You Need?

Most electricians in the Humber working in the Humber refinery and chemicals industry require:

  • Ex01 and Ex03 — Installation and inspection for IIA/IIB gas areas
  • Ex02 and Ex04 — Required for sites with IIC gas group areas (hydrogen, LNG)
Online Preparation — Study From the Humber

EX Academy is a fully online platform — no need to travel to a classroom. Study during evenings, offshore rotations, or at weekends. Your progress is saved automatically and you can access all 15 inspection simulations, 15 selection scenarios, and 1,185+ practice questions from any device.

What the CompEx Assessment Covers

The CompEx written assessment tests your knowledge of the IEC 60079 series — zone classification, protection types, deficiency classification, equipment selection, and inspection grades. The practical assessment tests your ability to apply this knowledge to real equipment. EX Academy prepares you for both.
