Is it safe to sweep asbestos insulation off the floor?

First year, first time working with asbestos. GC just came in and told everybody to sweep the asbestos up off the floor if it falls down, but not to go crazy with the broom.

I don't know anything about asbestos, but it seems to me we should have a vacuum with the HEPA filter on it. Am I right or wrong? What are the laws on this?
