Muting in practice: when safety becomes a vulnerability
Signal strongSource-grounded
What happened
Process Online reviewed how factory muting—temporary bypassing of safety devices—can be implemented in ways that create real safety gaps. It highlights failure modes like pallet-trigger workarounds and clearance gaps and references IEC 62046 requirements that are often unmet. Buyers should verify supplier implementations against the standard and watch for proposals that use cheaper single-trigger shortcuts
Why the category manager should care
Treat muting items as contract-level safety deliverables: require supplier testing, signed compliance statements and remediation liability because mis-implementation creates stop-work and remediation exposure
Key facts
- Muting must use at least two independent bridging signals per IEC 62046
- Standard limits maximum permissible clearance next to conveyed goods to prevent entry
- Common failure modes: pallet triggers and partially loaded pallets creating gaps
