For process plants and comah sites
One traceable IEC 61511 life cycle, from HAZOP to proof test
HAZOP actions, LOPA worksheets, SIF registers and proof test records often live in separate files owned by separate teams. MSA connects them, so a change in one place updates the evidence that depends on it.
Deliverables
- HAZOP worksheets
- LOPA calculations
- SIF Register
- SIL verification

Situations we solve
Sound familiar?
-
“Our HAZOP never made it into a SIF register.”
HAZOP to LOPA to SIF, linked per IEC 61511.
See how: Our HAZOP never made it into a SIF register. -
“Our integrator left no safety file.”
Rebuild the risk assessment and PL evidence.
See how: Our integrator left no safety file. -
“We modified a machine. Is it a substantial modification?”
Re-assess the change and see what it affects.
See how: We modified a machine. Is it a substantial modification? -
“We need an engineer to sign off, once.”
One-time review by a certified safety engineer.
See how: We need an engineer to sign off, once.
The challenge
Why the safety package takes so long
Evidence spread across spreadsheets
HAZOP, LOPA, SIL verification and proof testing are often maintained in disconnected documents.
Demonstrating all measures necessary
COMAH operators must show that major accident hazards are identified and controlled — and keep that demonstration current.
Sensitive plant data
Process data and P&IDs are commercially and security sensitive.
With MSA
From engineering inputs to signed-off evidence
- 01
Identify
HAZOP worksheets generated from P&IDs and process data, for your team to review.
- 02
Assess
LOPA calculations per scenario; gaps become SIFs with SIL targets.
- 03
Verify
SIF register, SIL verification and cause & effect matrix in one place.
- 04
Maintain
Proof test records and IEC 61511 life-cycle evidence — with optional CMSE-qualified review and competent person sign-off.
Standards
Standards you’ll work with
How we work with you
Expert Review & Certification Support
You use MSA with our safety experts. Best for regulated industries, comah sites, first-time certification.
Two ways to engage: Safety as SaaS for ongoing projects, or a One-time Safety Sign-off for a single machine or project.
- Everything in Self-Service, plus:
- CMSE-qualified engineering reviews
- Standards & gap verification
- Competent person sign-off
- Certification-ready deliverables
Frequently asked questions
Can our process data stay on site?
Yes. MSA runs 100% offline — no cloud dependency.
Who carries out the expert review?
With Expert Review & Certification Support, CMSE-qualified engineers review the evidence, verify it against the standards and gaps, and provide competent person sign-off.
