Muting in practice: when safety becomes a vulnerability
What happened
Process Online explains that muting — the temporary bypass of safety devices to allow material flow — is often implemented with practical gaps that can let people enter danger zones. The piece cites IEC 62046 requirements and practical limits such as a maximum 200 mm clearance and warns that common shortcuts (for example using pallets as triggers) are not permitted. Procurement should watch whether suppliers can provide IEC‑aligned designs and recorded acceptance evidence rather than promise fixes after mobilization
Why the category manager should care
Treat muting solutions as a technical deliverable with acceptance tests and recorded FAT/SAT; don’t accept supplier claims without evidence because handbook shortcuts create remediation cost and safety liability
Key facts
- IEC 62046 referenced as the governing standard
- Implementation constraint: maximum permissible clearance used in examples is 200 mm
- Common failure modes include pallet triggers and partially loaded pallets creating gaps
