Qualiman,
In our procedures for engineers writing a procedure that is a process, we stipulate that:
...if any condition is adverse to product quality...including operator safety, warnings and references to or directions to prevent damage to the product or operator are REQUIRED.
As an example, we use aerosol conformal coating. Good ventilation, a mask, and grounding are required due to the explosive hazard. These safety requirements MUST be mentioned in the procedure, or be referenced to an external procedure (e.g. "Please see MSDS...") that indicates the safety requirements.
To summarize, if the operator fails to utilize the proper safety equipment, would the material be damaged? Yes! It would - so therefore it is a reasonable requirement.
Keep being inventive!
