Not only the booby traps. There's also the powdered explosives that are spilled in all sorts of places. And, when you deal with homemade explosives... a disposal team always needs to consider them 'unstable'. Try cleaning that stuff up without subjecting it to impact shock. And with it spilled everywhere, you'd never get all of it even in a cleanup... hello sudden explosion when you shuffle across the kitchen to get breakfast, five years later.
