What 2025 Taught Us About Process Safety
Major incidents. Repeating patterns. Hard lessons.
2025 was not exceptional because of new hazards.
It was exceptional because the same old failure modes kept breaking through supposedly mature systems.
Across refineries, chemical plants, and transport corridors, incidents followed a familiar script:
- A known hazard
- A degraded or missing barrier
- Weak signals ignored
- Consequences felt far beyond the fence line
Below are the key process safety incidents of 2025, followed by the patterns that link them—and what we must do differently.
Benzene Train Derailment – Czech Republic (February 2025)
A freight train carrying over 1,000 tonnes of benzene derailed near Hustopeče nad Bečvou.
Around 400 tonnes were released, triggering a large fire, toxic vapour clouds, evacuations, and long-term soil and groundwater contamination.
Why this matters
- Benzene hazards are well understood.
- Transport risk is often treated as “outside” process safety.
- Emergency response quickly becomes a community-level problem.
Key lesson
- Major Accident Hazards do not stop at the plant gate.
- Transport risk belongs in enterprise PSM—not in a separate silo.
Key lesson
- Dust hazards are still systematically underestimated—especially in “non-energy” process units.
-
When dust isn’t owned by anyone, it becomes everyone’s problem after the explosion.
Microcrystalline Cellulose Dust Explosion – Telangana, India (June 2025)
A catastrophic combustible dust explosion killed dozens and devastated the facility.
Why this matters
- Dust explosion science is decades old.
- Housekeeping, ignition control, and enclosure protection were known weaknesses.
- Warning signs existed long before the event.
LPG Road Tanker Explosion – Iztapalapa, Mexico City (September 2025)
A road tanker carrying LPG overturned and exploded in a densely populated area, killing dozens and injuring many more.
Why this matters
- LPG transport risk is often normalized.
- Routing, parking controls, rollover protection and ignition control are inconsistent.
- Public exposure is extreme.
Key lesson
- Road transport of flammable gases is a Major Accident scenario, not a logistics detail.
Key lesson
- Road transport of flammable gases is a Major Accident scenario, not a logistics detail.
Multiple Fatal Chemical Plant Incidents – US, India, Norway (2025)
Across several countries, workers were killed during hydrogen handling, acid processing, gas releases, and maintenance activities.
Why this matters
- Different sites, same outcomes.
- Failures occurred during routine operations.
- Fatalities linked to isolation, containment, and control failures.
Molten Sulfur Train Fire – Kentucky, USA (December 2025)
A derailment caused molten sulfur release and fire, forcing emergency shelter-in-place orders.
Why this matters
- Non-toxic materials still generate toxic by-products.
- Emergency preparedness and communication were decisive factors.
- Community trust is fragile in such events.
Key lesson
- Emergency response capability is a safety barrier, not a last resort.
The Patterns We Can No Longer Ignore
Across all these incidents, the same systemic weaknesses appear:
None of these failures require new technology to fix. They require discipline, visibility, and accountability.
How SnSD Helps Prevent These Incidents
At SnSD, we do not sell safety slogans.
We work on the interfaces where incidents actually start.
From Hazard Lists to Live Risk Control
We translate HAZID, HAZOP and QRA outputs into:
- Clear Major Accident Scenarios
- Defined preventive and mitigative barriers
- Ownership at operator, supervisor, and management level
Barrier-Based Process Safety (IOGP-aligned)
We implement live barrier models that show:
- What barriers exist
- What condition they are in
- What is degrading—before failure occurs
No dashboards for show. Only decision-relevant insight.
Transport Risk Integrated into PSM
Rail, road and marine transport are treated as:
- Part of the process
- Part of the risk register
- Part of emergency preparedness
Not outsourced. Not ignored.
Practical Emergency Preparedness
We support:
- Credible emergency scenarios
- Clear escalation thresholds
- Realistic drills tied to actual MAH scenarios
No scripted exercises. No false confidence.
Leadership & Workforce Engagement
We help leadership teams:
- Understand their role in barrier health
- Act on weak signals
- Move from lagging indicators to learning systems
Because culture follows structure—not the other way around.
Final Thought
Every incident above was preventable.
Not with hindsight—but with existing knowledge that failed to translate into action.
If 2025 taught us one thing, it is this:
Process safety does not fail suddenly.
It erodes quietly—until it doesn’t.

SnSD is ready to work with you.
