Equipment Safety Certification (PLd/SIL2) Expired: Can Production Continue and What Are the Risks?
In European and global B2B industrial environments, equipment safety certifications such as PLd (Performance Level d) and SIL2 (Safety Integrity Level 2) are not optional—they are legal and contractual prerequisites for continued operation. When these certifications expire, many procurement and maintenance managers face a pressing question: Can we keep the line running, and what is the real risk?
The short answer is: operating equipment with an expired PLd or SIL2 assessment exposes your company to significant legal, financial, and safety risks. Under the EU Machinery Directive (2006/42/EC) and the new Machinery Regulation (2023/1230), machinery placed on the market or put into service must bear a valid CE marking supported by a current safety assessment. An expired certificate means the documented proof of conformity is no longer valid. In the event of an incident—even a minor one—regulatory authorities and insurers will consider the machinery non-compliant. This can lead to production stop orders, fines, voided insurance coverage, and liability for damages.
For procurement and maintenance teams, the practical approach is to treat an expired PLd/SIL2 as a critical red flag. The first step is to conduct a gap analysis between the original certification scope and the current machine state. Has any component been replaced? Has the control system been updated? Even if nothing changed, the certification body typically requires a periodic reassessment to confirm that the safety functions still meet the required performance levels. The recommended action is to initiate a recertification process with an accredited test house (e.g., TÜV, SGS, Bureau Veritas) before the expiry date. If production must continue during the recertification window, perform a documented risk assessment (per ISO 12100 and ISO 13849-1) and implement interim measures such as increased manual checks, restricted access, or temporary reduced speed. However, this is a high-risk bridge solution, not a long-term strategy.
| Risk Factor | Impact of Expired PLd/SIL2 | Recommended Action |
|---|---|---|
| Legal Compliance | Non-compliance with EU Machinery Directive/Regulation; potential fines and production halt orders | Initiate recertification immediately; engage accredited test body |
| Insurance Coverage | Claims may be rejected if accident occurs on non-certified equipment | Notify insurer; obtain written confirmation of coverage during interim period |
| Worker Safety | Increased probability of injury due to degraded or unverified safety functions | Perform interim risk assessment; restrict access; implement temporary safeguards |
| Procurement & Supply Chain | Buyers may reject products manufactured on non-compliant equipment; audit failures | Proactively inform key customers; plan supplier audits with recertification timeline |
| Equipment Value & Resale | Depreciation of asset value; difficulty in selling used machinery without valid cert | Budget for recertification as part of asset lifecycle management |
From a procurement perspective, when sourcing new or used equipment for European or global operations, always verify the validity of PLd/SIL2 certificates as part of your supplier qualification checklist. Insist on documentation from the supplier showing the date of last assessment and the next due date. For ongoing maintenance contracts, build in a clause that requires the supplier to notify you at least 90 days before any certification expiry. This proactive approach prevents production disruptions and ensures that your supply chain remains compliant with B2B buyer expectations in regulated markets like the EU, UK, and Switzerland.
In summary, an expired PLd/SIL2 is not a minor administrative lapse—it is a compliance and safety event that demands immediate action. The risk of continuing production without valid certification is high, both in terms of legal exposure and operational safety. The best practice is to embed recertification into your regular maintenance and procurement cycles, treating it as a non-negotiable element of equipment lifecycle management. For B2B buyers and suppliers in Europe and globally, transparency about certification status builds trust and reduces transaction risk.
