Visual Phase — Deficiencies Found
Missing bolts (6/8 fitted) CAT X
Non-barrier gland fitted CAT A
Paint on flamepath cover CAT A
Earth tag corroded CAT B

Mentor Feedback
Missing bolts on Ex d equipment is a Category X deficiency — the flamepath integrity is compromised. Equipment must be taken out of service immediately. IEC 60079-17 §6.3.2

Inspection Simulator

Would You Pass a Real
IEC 60079-17 Inspection?

Each simulation gives you a real work order — equipment tag, zone, gas group, certificate number, installed date. You inspect it the same way you would on site: visual first, then close, then detailed.

  • Inspect equipment and identify defects from scenario briefing
  • Classify each deficiency — Category X, A, B, or C
  • Receive instant expert feedback with standard references
  • Phase-by-phase scoring across Visual, Close, and Detailed inspection
  • CPD hours logged automatically on every pass

Close Inspection · Q14 of 20 Zone 1 IIC
The cable gland on Entry 1 has been removed for inspection. Thread engagement in the Ex d entry measures 3 full turns. Minimum requirement for Ex d threaded entries is 5 full turns. What is the correct classification?
No deficiency — thread engagement is acceptable
Category X — less than 5 full turns; flamepath integrity compromised ✓
Category A — note for rectification at next maintenance
Category B — monitor at next inspection
✓ Correct. IEC 60079-1 requires a minimum of 5 full thread turns for threaded cable entries into Ex d enclosures. 3 turns is insufficient — the flamepath is not maintained. This is Category X: take out of service immediately. IEC 60079-17 §6.3.4
Equipment Selection

Your Secret Weapon
For Ex Equipment Decisions

You'll be making real equipment selection decisions exactly like offshore electricians do — matching enclosures, glands, accessories, and earthing arrangements to the zone and protection type.

  • Zone, gas group, T-class, and EPL matching
  • Gland type selection — barrier vs non-barrier, entry type, volume rule
  • Accessory specification — IP washers, locknuts, serrated washers, earth tags
  • Body material rules — metal vs polyester continuity plate differences
  • IIC hydrogen area constraints — every component must be IIC rated

Scenario 01 · Ex d Junction Box Zone 1 IIB
ENCLOSURE: Metal · Threaded entries · Volume 2.5L
Entry 1 carries 4-core SWA XLPE 16mm² into this Ex d IIB metal junction box (2.5L internal volume) via M25 threaded entry. Select the correct gland type:
Ex d IIB non-barrier gland — threaded entry with 5 turns is always sufficient
Ex d IIB barrier gland — >2L enclosure requires barrier for SWA at threaded entries ✓
Ex e non-barrier gland — sufficient for SWA in any Ex enclosure
Standard IP66 brass gland — the Ex d enclosure provides protection

What Learners Are Saying

Built For The Real World

Finally a platform that makes you think like you're actually on the job. The inspection simulator is unlike anything else I've found for CompEx prep.

Offshore Electrician · Ex01/Ex02

The equipment selection scenarios are brilliant. I'd never really understood the barrier gland volume rule until I had to apply it in a real decision. It clicked immediately.

Instrument Technician · Ex03/Ex04

Walked into my CompEx assessment feeling genuinely prepared. The deficiency classification practice is exactly what the exam tests and nothing else covers it like this.
