I basically had the same approach as Mongo. I think i started of using a cartridge dust mask, but after a few days i just did like Mongo said (work upwind without mask) and was more deliberate & slow in attempt to not stir up dust when scooping & pouring into my mortar mixing container.
When I worked with most any mortar, i was using knit gloves with a nitrile (foam?) coating on the palm & fingers.

Wear a mask should you choose. If it's breezy out, be upwind of your dry mix so any airborne powder blows away from you. When done dry mixing, simply spray your arms down if you have a concern. If you make a mess, simply hose the area down. Dirty clothes, just wash them.
If you inhale clouds of any airborne dust daily, you could have problems. Just treat these materials with common sense respect. Don't work afraid. Work intelligently. Not meant as an insult, it's meant as encouragement.

Thanks,
To the point of dry grinding, doesn't the mortar come in 50 lb bags of powdered mix, which is very easily aerosoled? I assume it ends up all over your hands, clothes, and yard.

It is typically silica in the dust that is the issue. I used a dust mask rated to Noish95, common and not really expensive, others have used full blown respirators. Wet saws reduce some of the problem but dry grinding is always an issue.
