Everything certified.And still not right.
A plant builder delivers a hydrogen transfer station to a research institute. Material certificates complete, ATEX certificates for every component, leak test recorded, an explosion protection concept from an assessor. And the operating instructions fail to pass on one condition from that report — the one the non-hazardous classification depends on.
- A real, anonymised project
- Every point with a quotation and a source
- Check questions for the manufacturer, not legal advice
The knowledge agent behind this report is on Sheet 6 · Conformity. Where your data sits is your decision — three deployment models are set out on Sheet 1.
A project folder like any other.
Hydrogen, fluid group 1, outdoor installation, hazardous area. One-off build for a customer with its own safety function. The documentation is above average — that is not a courtesy, it is the reason this case is interesting.
Two documents, the same release date.
The explosion protection concept declares the plant non-hazardous, but ties that to two explicit conditions. The operating instructions the operator actually receives pass on neither in that form. Both documents were released on the same day — and the expert report refers to a draft from three days earlier.
Checking finds the contradiction. Writing stops it arising.
This report is a diagnosis: seven points, found after the fact. Checking after the fact is better than not at all — but it is not the point.
Finds the error once it exists
- The manual is written, released, signed
- Only then does the missing condition surface
- Somebody has to go back, correct, re-release
- And explain why
The error does not arise
- The agent derives the draft from template and documents
- The expert report is one of its sources
- The condition lands in the right chapter before anyone reads it
- What it cannot evidence, it reports
Seven points, each with a quotation and a source.
All phrased as questions — there may be an explanation for each that does not appear in the folder. A reported missing source is worth more than documentation that merely looks complete.
- Verbatim quotation for every point, with document, chapter and page
- Revision status of all seven P&ID versions and who references which
- Limits of the 26 bought-in parts, held against the plant nameplate
- Zone plan with the 8.6 metres and how much of it reached the operator
- Cross-check matrix expert report against manual, line by line
- Document index with release date and signatory
- Check questions on the Machinery Regulation scope of the four valves
- Withdrawn finding and why it did not hold
One finding had to be withdrawn — it rested on file names rather than on the drawing as read. That is exactly why the agent discloses the source for every point. What is not evidenced is marked as not evidenced.
What the agent may do. And what it may never do.
In machinery safety this boundary is not a formality, it is liability. A checklist asks whether the document is there. The question is whether it matches the next one.
This is what the agent does
- opens up the folder without anyone having to prepare anything
- derives the draft from template and documents
- carries every condition into the chapter where it belongs
- reports when a verification rests on a superseded revision
- evidences every point and flags what stays unevidenced
This stays with the engineer
- the technical judgement
- the decision on a substantial modification
- the declaration of conformity
- the signature
All seven points as a PDF.
With a quotation and source for every point, the four gaps at a glance and the line between agent and engineer. You get the PDF straight after submitting, plus a short email from me.
Four more process chains, same method.

We take a completed project of yours — you release the folder as it is, with no preparation. Exactly the effort you would otherwise face falls away. If we find nothing, it ends there and you have certainty.
