⚡ DAILY Ex - 3 OCTOBER 2026

Explosion Protection | Operational Ex | Global Watch

Today: combustible-dust regulation moves closer to implementation in Canada, a new ATEX/IECEx analyser can move directly into hazardous areas, and new hydrogen research asks an increasingly important question: how do we turn hazard assessment into an operational decision?

▶️ COMBUSTIBLE DUST - FROM “DUST EXISTS” TO A MANAGEMENT PROGRAMME

CURRENT REGULATORY | Canada - 2 October

Yesterday was the closing date for stakeholder feedback on four new https://www.worksafebc.com/en/law-policy/public-hearings-consultations/current-public-hearings-and-consultations covering: reasonably foreseeable combustible-dust risk → dust testing → competent/qualified persons → combustible-dust management programmes.

The underlying amendments to British Columbia's OHS Regulation take effect on 4 January 2027.

This is worth watching internationally because the direction is important.

The question is moving beyond: “Is this dust combustible?”

toward: “How does the organisation continuously manage that risk?”

That means responsibilities, assessment, controls, inspection, housekeeping, competence and continual improvement.

Why it matters operationally: combustible-dust safety should behave like a management system, not a one-time DHA/HAC exercise.

▶️ HYDROGEN RESEARCH - FROM HAZARD ASSESSMENT TO OPERATIONAL ACTION

CURRENT RESEARCH | published 29 September

A newly published study proposes a framework specifically for translating hydrogen hazard information into operational intervention decisions when probability data are incomplete. The work draws on a structured evidence review, regulatory material and hydrogen incident records.

That is an interesting direction for Operational Ex.

Risk assessment often ends with: low / medium / high or a coloured matrix.

Operations needs something different: What do I do? Continue operation? Apply compensating controls? Restrict operation? Repair immediately? Escalate? STOP?

Why it matters: risk information becomes useful only when it leads to a defined decision, responsible person and deadline.

▶️ HYDROGEN - HIGH-PRESSURE RELEASE MAY IGNITE WITHOUT THE IGNITION SOURCE WE EXPECT

CURRENT RESEARCH | September 2026

Experimental research in Fire Safety Journal investigated spontaneous ignition during 3–25 MPa high-pressure hydrogen releases.

The experiments found that the rupture process itself strongly influenced shock-wave behaviour and subsequent self-ignition/jet-fire development.

This deserves attention because conventional Ex thinking often follows: release → explosive atmosphere → separate ignition source.

With high-pressure hydrogen, rapid release phenomena themselves can contribute to ignition mechanisms.

Operational lesson: removing conventional electrical ignition sources does not mean the hydrogen release scenario is safe.

Pressure, release geometry, confinement and failure mode matter too.

▶️ UPCOMING - PROCESS SAFETY FOCUS IN KUWAIT

CURRENT EVENT | 4–5 October

The 13th International HSSE & Loss Prevention Professional Development Conference starts tomorrow in Kuwait, bringing together process-safety professionals, regulators and industry leaders around process safety, operational excellence and risk management.

For Operational Ex, this interface matters.

Explosion protection should not become an isolated technical island: Process Safety ↔️ Mechanical Integrity ↔️ Functional Safety ↔️ Work Safety ↔️ Fire Protection ↔️ Operational Ex

Each discipline owns part of the barrier system.

Operations sits where those interfaces meet.

▶️ INCIDENT FOLLOW-UP - CLEANUP IS ALSO PART OF THE INCIDENT

CURRENT FOLLOW-UP | USA - 2 October

Authorities in Toledo, Ohio reported yesterday that cleanup following the August fire and building collapse at Brent Industries has entered its final phase.

The original incident killed two people. Contaminated runoff has now been contained, impacted soil removed and affected tanks remediated. Ohio EPA is awaiting waste-sample results before final disposal and closure of the environmental response.

This is not being presented as a confirmed Ex accident.

But there is a useful management lesson: incident consequence does not finish when the fire is extinguished.

Emergency response can become: fire → contaminated firefighting water → soil contamination → hazardous waste → environmental recovery → restart conditions.

Explosion/fire emergency planning should therefore look beyond the first few hours.

▶️ OPERATIONAL Ex USE CASE - THE NEW POWDER SUPPLIER

PRACTICAL

Procurement finds a cheaper supplier.

Same product name. Same process. Same equipment.

So no MoC? Not necessarily.

The new powder may have different: particle-size distribution → moisture → resistivity → MIE → MEC → KSt → Pmax.

Operations sees: “same powder.”

Explosion protection may see: different material behaviour.

Before approving the substitution, ask: Are the explosion characteristics used in our HAC / DHA / ignition assessment and explosion-protection design still representative?

A purchasing decision can become an Ex Management of Change.

▶️ GOOD ENGINEERING PRACTICE - WALK THE DUST, NOT JUST THE DRAWING

Choose one powder-handling process today. Start where the material enters.

Then physically follow: unloading → conveying → processing → extraction → filter → hopper → waste collection.

Look for where dust can: escape → accumulate → become airborne → migrate → enter equipment → reach an ignition source.

Then compare what you see with the hazardous-area documentation.

A drawing shows where the hazardous area was expected to be.

Operations tells you where the dust actually goes.

▶️ TODAY'S Ex QUESTION

Ask one simple question during today's plant walk:

“What changed here since the Ex assessment was completed?”

New product? Higher production rate? Different cleaning method? Replacement motor? Temporary hose? Modified ventilation?

New contractor? Different maintenance interval?

If the answer is “yes”, the next question is: “Did that change enter our Ex Management of Change process?”

That is Operational Ex.

Not continuously redesigning the plant — continuously protecting the assumptions that made the plant safe.
