Machine risk assessment software is not a nice-to-have: it's the foundation on which compliance with the Machinery Directive and the new Regulation (EU) 2023/1230 is built. Risk analysis according to ISO 12100 and compliance with the Essential Safety Requirements (ESR) of Annex III require method, traceability and documentation that stays aligned. Do it by hand in Word or Excel, and the time multiplies while the risk of outdated documents — during an inspection — becomes real. In this article we look at the limits of traditional methods, what modern machine risk assessment software should have, and how Reesly revolutionizes the process.
The Limits of Traditional Methods: Word and Excel Are the Enemies of Compliance
Many companies still carry out risk assessment in spreadsheets or Word documents. It seems cheap. In reality you pay in time, errors and regulatory risk. Here's why Word and Excel aren't suited to a serious Technical File.
- Lack of standardization. Every project has different formulas, cells that break, "final" versions that aren't. No guarantee that severity, probability and residual risk are calculated the same way across every machine.
- Calculation errors. A wrong formula in a risk matrix can cause a residual risk to be underestimated. In the event of an accident or inspection, that Excel sheet becomes evidence that the assessment was inadequate.
- Difficulty keeping up with harmonised standards. The move to Machinery Regulation 2023/1230 introduces new obligations (the machine's digital identity, electronic formats). Manually updating dozens of Word and Excel files is slow and prone to oversights.
- No structured link to the ESRs. The Essential Safety Requirements (ESR, Annex III) must be addressed explicitly. In Excel they're often just a list on another sheet, not a guided flow that ensures full coverage.
In short: Word and Excel are great for many things, but not for managing risk assessment in a way that's compliant, repeatable and defensible during an inspection.
What Modern Machine Risk Assessment Software Should Have
Machine risk assessment software worthy of the name isn't "Excel with extra steps." It has to integrate the standard, the ESRs and documentation into a single flow. Here are the non-negotiable requirements.
- Pre-loaded hazard database (ISO 12100). ISO 12100 risk analysis starts with the systematic identification of hazards. Serious software offers a library of typical hazards (mechanical, electrical, thermal, noise, etc.) so you don't start from scratch and reduce the risk of oversights.
- Integration with the Essential Safety Requirements (ESR). The ESRs of Annex III must be considered during design and assessment. The software should guide you point by point and track which ESRs you've addressed and how.
- Automatic PL (Performance Level) or SIL calculation. Where safety depends on control system parts, you need PLr (ISO 13849-1) or SIL (IEC 62061). Good machine risk assessment software supports the calculation, or at least the structured entry, of the required level, linked to the risks.
- Instant report generation for the Technical File. The result of the assessment must flow into the Technical File without copy-pasting. A report in a consistent format, always aligned with the manual and the EC Declaration: that's the heart of the digital Technical File.
If a tool doesn't do at least this, it's not real machine risk assessment software: it's a compromise that still exposes you to inconsistencies and delays.
Reesly: The Revolution in CE Marking
Reesly is a modern, fast and intuitive SaaS that automates the creation of the Technical File and, in particular, risk assessment according to ISO 12100 and the ESRs. It's not a module "bolted on afterwards": risk assessment is a native part of the CE marking flow.
Why Reesly Makes a Difference
- A clean interface and step-by-step guidance. No endless spreadsheets: the process guides you from hazard identification to the matrix, to protective measures and residual risk, with contextual suggestions.
- Cloud-based: always up to date. Reesly is built for Machinery Regulation 2023/1230. Regulatory updates and improvements are included; you're never stuck with a "frozen" version on a PC.
- A single environment for the file, manual and EC Declaration. The risk assessment automatically feeds the Technical File and the instructions manual. No duplication, no inconsistencies between documents.
- Ready for inspections. Consistent, traceable documentation accessible in one click. If you're inspected, everything is in order, aligned with the latest regulation.
It's a revolution not because it "does the calculations for you," but because it brings together risk assessment, ESRs and the digital Technical File in a single flow. Less time, fewer errors, more certainty.
The Competitive Advantage: Time and Legal Certainty
Two things matter more than anything else: the time you save and the certainty you have during inspections.
- Up to 70% less drafting time. Companies moving from Excel/Word to Reesly report a drastic drop in the hours spent on the Technical File and risk assessment. Less copy-pasting, less "where did I put the latest version?", more focus on the technical content.
- Legal certainty during inspections. Structured documentation, aligned with Regulation 2023/1230 and with clear traceability (hazards → measures → residual risk → manual) reduces regulatory risk and protects you from challenges over outdated or inconsistent documents.
Machine risk assessment software like Reesly isn't just "more convenient": it's a tool for defense and efficiency. In 2026, with ever-stricter regulations, you can no longer afford to stay on Excel.
| Aspect | Word / Excel | Reesly Risk Assessment Software |
|---|---|---|
| Standardization | Different formulas and versions per project | A single process, a consistent ISO 12100 matrix |
| Risk / PL-SIL calculation | Manual, error-prone | Automatic and traceable |
| ESR link (Annex III) | Often missing or disorganized | Integrated and guided |
| Report for the Technical File | Copy-paste, risk of inconsistencies | Instant generation, always aligned |
| Regulation 2023/1230 updates | On you, file by file | Cloud-based, always up to date |
Reesly ProTip
Use Reesly's hazard database as a checklist: even if you know your machine well, scroll through the library so you don't forget "side" risks (noise, ergonomics, maintenance). The final report will hold up better during an inspection.
Frequently Asked Questions
What is machine risk assessment software?
It's a tool that supports risk analysis according to ISO 12100: a hazard database, a severity x probability matrix, a link to the Essential Safety Requirements (ESR), PL/SIL calculation and report generation for the Technical File. It integrates all of this into a single flow, aligned with Machinery Regulation 2023/1230.
Why not use Excel for risk assessment?
Excel doesn't standardize the process, exposes you to calculation errors, doesn't update with harmonised standards, and doesn't automatically link risks to the Technical File and manual. During an inspection, inconsistent or outdated documentation increases regulatory risk and the chance of penalties.
Does Reesly include risk assessment according to ISO 12100?
Yes. Reesly is machine risk assessment software with a pre-loaded hazard database, integration with the ESRs (Annex III), support for Performance Level (PL) or SIL calculation, and instant report generation for the Technical File. All cloud-based and kept up to date with EU Regulation 2023/1230.
