Security at Craig Ferguson's "Late Late Show" didn't take any chances during last month's anthrax scare -- telling the 911 operator they immediately quarantined everyone who had contact with the white powder as soon as they could.

TMZ obtained a copy of the 911 call -- made by a very cool, calm and collected security guard who wasn't one of the five people exposed to the powder.

So far, no arrests have been made.
