This article by Doug Copp, rescue chief and disaster manager of the American Rescue International, is again going the rounds of the internet following the earthquake in China that has claimed the lives of more than 40,000 people.
Copp says “when buildings collapse, the weight of the ceilings falling upon the objects or furniture inside crushes these objects, leaving a space or void next to them. This space is what I call the ‘triangle of life’. The larger the object, the stronger, the less it will compact. The less the object compacts, the larger the void, the greater the probability that the person who is using this void for safety will not be injured. The next time you watch collapsed buildings, on television, count the ‘triangles’ you see formed. They
are everywhere. It is the most common shape, you will see, in a
collapsed building.”
