It's clear from the discussion here that many just don't appreciate the nature of mercury, and that many of those commenting have never actually handled the material.
Permit me to address a few points:
1. Taking students to the hospital for "decontamination" was over-reaction, absolutely yes. It was also the worst thing that could have been done if there was serious contamination. That would have spread the mess to the transport vehicles, the hospital, etc. etc. etc..
2. The ability of mercury to "shatter" into tiny, tiny droplets literally increases its surface area by a factor of **one million** compared to a single small pool. This not only makes cleanup very difficult, it makes the evaporation rate increase by orders of magnitude. As one doesn't know the size and physical distribution of the droplets, any calculations about how long it would take to all evaporate is nothing more than complete conjecture, whether we're guessing at how long it would take all the mercury to "go away" or whether the concentrations would become dangerous.
