Why they dont immediately remove rubble from a building collapse when one occurs.
In: Engineering
Adding on to many other helpful comments: most people don’t realize that excavators and other heavy machinery essentially do their job by pushing large amounts of material around. So, even if you identify someone trapped in the rubble in a place where further structural collapses aren’t a problem, you have to dig them out by hand. Using machinery will just shove more debris onto them, crushing them to death.
Incidentally this is often the mistake people make when workers are trapped by mounds of dirt in collapsed trenches, or other dig sites. Trying to dig them out with an excavator is more likely to get them killed than not. You have to use a shovel.
