It still would have made a lot of sense to recommend that users wear a face mask. I worked in the coatings industry for decades. Face masks are required when handling any and all pigments. Breathing a solid material in is not good practice. Workers got fired for not following the rules. Why was this common sense practice not presented to mothers and fathers. The bigger problem is protecting the baby from breathing in the dust. It can cause asthma.
