In a story about today's Miami bridge collapse, I saw this photo:
In the upper left, there is a white box truck which seems to say "MIAMI DADE FIRE RESCUE / TECHNICAL RESCUE / COLLAPSE UNIT," even though the start of each line is obscured by a pole.
First responders, including another fire truck, are visible on the scene and one of the crushed passenger vehicles' headlights are still on. (Reports indicate the crushed vehicles were stopped for a red light). The disaster scene looks pretty fresh, though clear of bloodied victims and easily clearable bystanders.
However, collapses like this are supposed to be quite rare. The impressive observation that such a specialized unit got there so quickly got me wondering, how many of these units are there?
Recognizing that collapses might be more common in countries with weaker building codes, and thus Collapse Units like this might be more necessary there, I'm primarily restricting the scope of this to the US.
