⚡ DAILY Ex - 9 OCTOBER 2026

Explosion Protection | Operational Ex | Global Watch

Today's focus: The hidden gap between Ex compliance and operational readiness.

A machine may be certified, an installation inspected and the documentation complete. Yet an explosion-prevention barrier can still become ineffective through changed operating conditions, deferred maintenance or an unauthorized modification.

Today's edition separates recent developments from established engineering practice, with particular attention to what the Head of Operations needs to know, decide and verify.

▶️ 1. INDUSTRIAL FIRE AND EXPLOSION - PERTH, SCOTLAND

CURRENT INCIDENT | 8 October

A significant fire broke out yesterday at an industrial estate near Arran Road in Perth. The Scottish Fire and Rescue Service dispatched four fire appliances and a high-reach vehicle after receiving the alarm at approximately 13:08.

Footage captured a large fireball emerging from a building. No casualties were reported, and police said the incident was not being treated as suspicious. The cause and materials involved have not yet been established. https://www.thescottishsun.co.uk/news/16915899/explosion-industrial-estate-fire-service-police-perth/

Operational Ex lesson: A visible fireball does not, by itself, establish whether the event was a gas explosion, dust deflagration, pressure-vessel failure or another phenomenon.

Before recommending corrective actions, establish the sequence:

Initial event → fuel or energy source → containment failure → ignition → escalation → damage.

▶️ 2. PROCESS SAFETY - TURNING ACTIONS INTO OUTCOMES

RECENT EVENT | Türkiye - 8 October

Yesterday's inaugural PSRG EMEA Process Safety Day in Istanbul brought together combustible-dust prevention, ATEX compliance, process-safety KPIs and performance improvement under one theme: Process Safety Performance Measurement & Improvement. psrgroup.com

For a Head of Operations, this raises an important question:

Are we measuring inspection activity, or the actual restoration of Ex integrity?

Completing 500 inspections is an activity.

Closing 40 significant defects, verifying the repairs and eliminating recurring causes are measurable outcomes.

A useful monthly Ex dashboard should therefore track critical open defects, overdue corrective actions, repeat findings, temporary deviations and unavailable protection barriers.

▶️ 3. RESEARCH - EXPLOSIONS INSIDE PROCESS BUILDINGS

2026 RESEARCH | USA

A 2026 AIChE conference paper examines confined explosions in enclosed process buildings, reviewing incidents investigated by the US Chemical Safety Board between 1998 and 2025.

The authors' preliminary analysis identifies at least 20 fatalities and 123 injuries associated with confined explosions in the cases studied. The research calls for better integration of building-confinement effects into process hazard analyses and quantitative risk assessments. https://proceedings.aiche.org/conferences/aiche-spring-meeting-and-global-congress-process-safety/2026/proceeding-745

Operational Ex lesson: Hazardous-area classification addresses the likelihood and extent of explosive atmospheres. It does not, by itself, establish the consequences of an explosion inside a congested or enclosed building.

Ask whether the assessment considers:

ventilation → congestion → confinement → explosion pressure → structural consequences → occupied areas.

▶️ 4. NEXT WEEK - EXPLOSION SAFETY FOR SMALL PRODUCTION UNITS

UPCOMING | Germany - 14–15 October

The European Process Safety Centre's technical meeting in Cologne includes a session on explosion safety for small production units, alongside discussions about maintaining process-safety performance during economic downturns. https://www.epsc.be/events/event-detail/14/epsc-technical-meeting-14-15-october-2026-in-cologne/schedule

This is particularly relevant to smaller chemical, pharmaceutical and batch-processing operations.

A small production unit may have limited staffing and maintenance resources, but that does not reduce the consequences of an uncontrolled release.

Operational question: Does the complexity of the explosion-protection management system match the actual hazards, or merely the size of the organisation?

▶️ 5. COMBUSTIBLE DUST - LIVE DEMONSTRATIONS IN KRAKÓW

UPCOMING | Poland - 14–15 October

The SYMAS and Maintenance exhibitions in Kraków will feature dust-explosion demonstrations, protective systems and industrial safety discussions. Organisers expect approximately 160 exhibitors. https://www.plastech.pl/en/news/symas-and-maintenance-process-safety-in-practice-22866

Why it matters: Live demonstrations can help operators understand why explosion protection is a system rather than a single device.

Detection → venting or suppression → isolation → prevention of propagation.

For maintenance teams, the critical issue is knowing which devices must remain functional, how their readiness is verified and what conditions require shutdown.

▶️ 6. STANDARDS & COMPETENCE - WHO ACCEPTS AN Ex DEFECT?

EVERGREEN | IEC 60079-14 / -17 / -19

An inspector identifies a damaged Ex cable entry.

Maintenance believes it can wait until shutdown.

Operations wants production to continue.

Who decides?

The inspection standard helps establish the condition. The repair standard provides requirements for restoring equipment. Neither substitutes for the operator's responsibility to assess the defect and control continued operation.

Operational lesson: Every significant Ex finding needs a competent assessment, a documented decision, an owner, a deadline and verification of close-out.

If Ex integrity cannot be maintained, continued operation should not be authorized.

▶️ 7. OPERATIONAL Ex USE CASE - THE TEMPORARY EXTRACTION FAN

PRACTICAL

A powder-processing line develops an extraction problem.

Maintenance installs a temporary fan to keep production running.

Airflow improves. Production continues.

But the temporary arrangement has changed the extraction system.

Potential consequences include: altered airflow → dust deposits in unexpected locations → changes in hazardous-area extent → different electrostatic conditions → unsuitable fan or motor → impaired explosion isolation.

The fan may be perfectly functional while the overall explosion-prevention system is no longer operating as assessed.

Before accepting the modification, Operations should require an engineering review, equipment suitability verification, temporary operating limits, monitoring and a defined removal date.

Temporary does not mean exempt from MoC.

▶️ TODAY'S Ex QUESTION

“Which of our explosion-prevention barriers are currently operating under a temporary arrangement?”

Consider temporary ventilation, bypassed alarms, alternative inert-gas supplies, provisional electrical installations and modified extraction systems.

For each arrangement, identify: Responsible owner → technical justification → compensating controls → expiry date → verification of safe operation.

Then ask one final question: “Who has the authority to stop operation if the temporary arrangement no longer provides the required protection?”

DAILY Ex | Closing thought

An Ex certificate tells us what equipment was assessed to do.

An inspection tells us something about its condition.

Operational Ex must establish whether the complete protection system is still effective under today's actual operating conditions.

That is where engineering, maintenance and the Head of Operations meet.
