It's already in
The manufacturing site assessment required for Ford Q1 already includes the following requirement:
"Supplier's QOS has safety as one of the metrics"
and amongst the notes is the following statement:
"Operator Safety (OS) characteristics are related to parameters that do not affect the product but may have an impact on the safety or governmental regulations applicable for the process operation, e.g., Occupational Safety and Health Administration [OSHA] requirements, Ford Health and Safety Specifications. This is a hazard for in-plant operators. These characteristics should be included on a safety signoff. These are failure modes with a severity rating of 9 or 10 due to an effect of the process on the process operator."
