At Shelburne Museum, we apply a calcium chloride solution to our dirt roads once every one or two years to control dust and it works well for that purpose. We keep it well away from buildings as it can leach up into bricks or porous stone building materials. I agree with Dale that it would not be safe to use inside collection buildings. It will only work to control humidity in small sealed spaces and silica gel sealed into “tiles” is a safer, more controllable, and probably more effective product to control humidity in microclimates.
