Keeping mineral wool exposed without constant dust?

Hi,

A few places in my basement ceiling cannot be finished with sheetrock: abov e the electrical panel, the concrete block wall behind the boiler, etc, due to too many pipes or electrical conduits. Yet I still need to maintain a fire rated ceiling in those locations. The building inspector says use roc k wool in those locations.

How can I do this and not have a constant sprinkle of rockwool fibers direc tly under these places? Just curious what other people have done. (I had a thought to use a spraypaint clear-coat on the rockwool after it's install ed, but that's probably not compatible with the whole fire-rated ceiling th eory. Advice appreciated.

Thanks Theodore

I think this stuff is stable. Stuff I saw had a solid feel to it.

Many years ago I was working on a project in New York City that had a lot o f firewall penetrations. The general contractor used mineral wool insulati on with some sort of fire caulk or paste smeared over it. It came in five gallon buckets. I don't know the name of it, but perhaps your local buildi ng supply knows what it is.
