Chemicals, Petrochemicals & Fertilizers Incident Investigation
Process safety fails quietly. Then it fails loudly.
Chemical plants, petrochemical complexes, fertilizer and urea plants, and chemical storage and distribution, where a small deviation, a bypassed trip or an unreviewed change can escalate into a major event. We work across Karachi, Port Qasim, Multan, Sheikhupura, Daharki, and in the Gulf.

for a P3i lead investigator to be engaged after a high-potential event.
P3i service commitment
In Pakistan
Fertilizer and chemical plants in Pakistan run large inventories of hazardous material, often close to towns, and serious events draw immediate public and regulatory attention.
Globally
Internationally, major chemical accidents over the past fifty years reshaped process safety management, and investigation boards publish detailed findings for industry to learn from.
Photographs illustrate typical settings; they are not from P3i cases.
Follow one change through the plant
Follow one change. Watch the hazard build.
Most process events we investigate began with a change nobody reviewed.

Drawings and procedures lag behind
The plant changes; the drawings, alarms and operating instructions do not.

Something happened on your site this week? A first call costs nothing, and we will tell you what to preserve today.
The P3i approach
How we investigate chemical & fertilizer incidents. Fact-finding, not fault-finding.
Every P3i investigation is led by a senior investigator and supported by internationally qualified process specialists. You will not receive a list of people to blame, or a long list of generic actions. You will receive the facts, the proven causes, and a short plan that closes the gaps, in this case and across your system.
Independent
No products, repairs or contracts to sell you afterwards.
Senior-led
Thirty years of investigation, from the first call to the final briefing.
Beyond the event
Process specialists find the other cracks before they fail.
Ready to present
Written for boards, buyers, insurers and regulators.
How P3i does it for you
- 01
One confidential call
We help you make the site safe, preserve the evidence and scope a process safety investigation.
- 02
Secure before it is cleaned up
Trends, alarms, trip logs and the failed item secured.
- 03
Facts, not versions
Private interviews where nobody is pushed to name a culprit. The evidence decides.
- 04
Find what the system allowed
Barriers, management of change and trips that were bypassed.
- 05
A plan leadership can approve
Short, costed, owned actions, and a check that they worked.
What you receive
Call us when
Free 30-minute case assessment.
Tell us what happened. In confidence, we will tell you what the investigation should cover, how long it will take and what to preserve today.
How we work with you
What happens after you call.
For chemicals, petrochemicals & fertilizers, the first call covers what happened, what must be preserved, and who needs to be involved. From there, this is the usual pattern.
First hour
A call with a lead investigator. You leave it knowing what to preserve today and who to call next.
Day one
An investigator on site, anywhere in Pakistan. Scope and fixed fee agreed in writing.
Week one
A private briefing on early findings, so urgent risks are dealt with before the report is finished.
Weeks three to four
The final report, the wider system review and a remedial work plan, presented to your team.
After
We come back to check the actions were completed and actually worked.
Typical timings for a single-site event. Complex, multi-party matters take longer, and we tell you so on the first call.
What you receive
A full investigation report. This is only its first page.
The summary is what leadership reads first. Behind it sits the complete file: every witness heard, every document and record examined, and every finding tied to numbered evidence, so a board, an insurer, a buyer or a regulator can test it.

Questions
What process safety leads ask us first.
Can you investigate a process upset with no injury?
Yes. Upsets and near misses are where the most valuable learning is.
Do you work alongside our technical licensors?
Yes. We coordinate with licensors, OEMs and specialist engineers.
Do your findings support our regulator response?
Yes. They are written to support any engagement with the authorities.
