FSMS Document Templates
Your FSMS, ready on day one. Not built from scratch under project pressure.
IEC 61508 Part 1 Clause 6 requires a functional safety management system in place before SIS lifecycle activities begin — and IEC 61511 carries the same requirement through Clause 5. This pack gives you that governance structure on day one: up to 41 procedures, templates and live registers across three tiers, written to IEC 61508 and IEC 61511 with nuclear and defence regulatory context built in, not retrofitted. From Project-Ready up, the procedures are mapped to CASS assessment criteria — so the pack supports your path to CASS accreditation, not just IEC 61508/61511 compliance.
This isn't optional — it's a prerequisite.
IEC 61508 Part 1 Clause 6 requires that a functional safety management system is established, documented and maintained before SIS lifecycle activities begin. It's a prerequisite, not a recommendation — and IEC 61511 carries an equivalent requirement through Clause 5. Without it, you can't legitimately claim your SIL verification is supported by a compliant governance framework, however good the underlying engineering is.
For nuclear projects the obligation goes further: ONR expects functional safety governance to be demonstrable against NS-TAST guidance, and a gap in your FSMS isn't just a non-conformance — it's a regulatory exposure.
Most organisations assume this is covered somewhere in their QMS. Most of the time it isn't — and the gap becomes visible at exactly the moment it's most expensive to close.
Building it from scratch costs you twice.
When a project starts, functional safety documentation is rarely ready. Most organisations have a QMS but no FSMS, and no one has time to build one properly under delivery pressure. So procedures get written reactively, by whoever's available; gaps appear at design approval, during an FSA, or at handover; and your functional safety engineers end up writing procedures instead of applying them — the wrong use of the most expensive people on the project.
I've seen the absence of a documented FSMS surface at design review on a major multi-SIS nuclear project: months of delay, significant rework, and liquidated-damages exposure — all avoidable if governance had been in place at the start.
Pick the level your project actually needs.
Each tier is built around a different outcome — not just more documents. Pick the tier that matches where you are; upgrade later and pay only the difference.
12 documents
Audit-Ready
Proves the management system exists. Pass any IEC 61511 audit with a defensible FSMS.
30 documents
Project-Ready
Ships a complete SIS project, hazard analysis to validation. Every procedure has its matching fillable deliverable. Mapped to CASS assessment criteria.
41 documents
Asset-Ready
Runs the SIS for the full 20+ year asset lifetime, with live operational registers. Mapped to CASS assessment criteria.
Built for real projects. Not for compliance theatre.
Written by a practising CFSE and TÜV Functional Safety Engineer with 20+ years on live projects — so when an auditor or assessor reviews these documents, they find the specificity that comes from someone who's sat on both sides of the conversation.
Dual-standard aligned: IEC 61508:2010 primary, IEC 61511:2016 overlay, with nuclear regulatory context (ONR, NS-TAST-GD-003, NS-TAST-GD-046) built into the documents — not retrofitted.
Each document is a controlled, referenced procedure ready to sit under your existing QMS. Document numbers, revision control and classification are already in place — you adapt the content, not the structure.
Written nuclear-first. Most commercial packs are process-industry IEC 61511 documents adapted for nuclear and defence. This one was written the other way around — for your environment, not hoping a process pack fits.
ON THE PATH TO CASS ACCREDITATION
Built to support your route to CASS accreditation.
From Project-Ready up, the procedures aren't just aligned to IEC 61508 and 61511 — they're mapped to the CASS assessment criteria your organisation will be measured against. For a consultancy or contractor pursuing CASS accreditation, that mapping is the foundation work already done: a documented functional safety capability structured to what a CASS assessor looks for.
Please note:
CASS accreditation is awarded following a formal CASS assessment of your organisation by an accredited body. These documents give you the aligned, mapped foundation to take into that process — they don't replace the assessment itself.

Not sure which tier — or need it tailored?
If you need the pack adapted to your organisation, a white-label arrangement for delivering to clients, or you're just not sure which tier fits your project, book a short call and I'll point you to the right option.
If you're starting a project without an FSMS.
This is written for the engineering or safety manager at a contractor or operator who's been handed accountability for functional safety governance and needs a compliant, structured FSMS in place before the project gets moving — not in six weeks, now.
Tier 1 suits the engineer or small consultancy proving the FSMS exists for audit; Tier 2 the active consultant or in-house team delivering SIS projects; Tier 3 the operator or consultancy running the SIS for the full asset lifetime.
Particularly useful in nuclear and defence, where ONR expectations and NS-TAST guidance apply alongside IEC 61508/61511 — and for oil, gas and process projects implementing these standards for the first time.
Three tiers. One payment. Yours to use.
A functional safety consultant costs £800–£1,200 a day. Writing a compliant, IEC 61508-aligned FSMS from scratch at this level of specificity takes an experienced engineer six to twelve weeks — £30,000–£60,000 of resource before a single project activity starts. And if the absence of an FSMS is found at design review, the cost isn't the price on this page. It's months of delay, rework, and liquidated-damages exposure.
