Process Knowledge Management
The process safety information dossier covering chemistry, technology, and equipment, kept current through MOC
What this element is and why it matters
Process Knowledge Management is the living dossier of everything your site needs to know about its process in order to run it safely, from chemical hazards and reaction kinetics through equipment ratings, P&IDs, electrical classification, relief device sizing, and control logic to the operating envelopes themselves. It maps onto the Process Safety Information requirements of OSHA PSM 1910.119(d). Bhopal, Texas City, and BP Macondo each surfaced process safety information findings, with operators making decisions from documentation that no longer matched the plant, and our team exists to make sure that gap never opens at your facility.

Individual significance for organisations
Process knowledge is the single most leveraged asset an operating organisation holds. Every decision, whether operational, engineering, MOC related, or emergency response, depends on it. An organisation with accurate, accessible, and current process safety information operates with confidence, while one without it carries hidden risk into every decision. The quality of that information correlates directly with PHA quality, MOC discipline, and the depth of incident investigation.
Contribution to Risk Based Process Safety (RBPS)
Process Knowledge Management is the prerequisite for Hazard Identification and Risk Analysis (Element 7), because without accurate process safety information a PHA runs on bad data. It also feeds Operating Procedures (Element 8), Asset Integrity (Element 10), MOC (Element 13), and Incident Investigation (Element 17). RBPS positions this element first in pillar two precisely because every downstream risk management activity rests on it.
What compliant execution looks like
How we implement this element
A focused six step methodology calibrated to deliver process knowledge management as a working capability rather than a documented compliance artefact.
We inventory the required process safety information per OSHA 1910.119(d) across chemical, technology, and equipment, and identify the current state, the gaps, and any version control issues.
We specify the document hierarchy, naming conventions, version control, and access control, and integrate it with your electronic document management system such as Aveva PI, Documentum, or OpenText.
We walk down the P&IDs against field reality, update the markups, reissue them as as built, and cross check against your HAZOP and PHA records.
We compile equipment datasheets, materials of construction, MAWP, MAOP, and relief device sizing per API 520, 521, and 2000, and align it with the mechanical integrity register.
We define the MOC procedure trigger for a process safety information update, enforce that update before MOC closure, and track information lag time as a leading KPI.
We make sure operating teams hold read access to the information relevant to their unit, train them on how to navigate it, and integrate it with shift handover.
Element implementation flow chart
A decision gated workflow that shows the actual sequence of activities from initiation through steady state operation, with key decision points highlighted.
What we produce
- A process safety information inventory and gap register per OSHA 1910.119(d)
- A document hierarchy and version control procedure
- A walked down as built P&ID and PFD set
- An equipment, relief, and hazardous area classification data pack
- An MOC procedure with process safety information update enforcement
- An operator information access matrix and training plan
Where execution fails
- Stale P&IDs that do not reflect ten years of modifications
- Missing relief calculations for vintage equipment
- An MOC backlog that leaves the information register lagging reality
- Operator access blocked by document management system permission issues
