Testing your equipment is important, but using the right methods is essential to the safety of your industrial processes and your machinery. I recently went on vacation to Cartagena, Colombia, and I encountered many street vendors that use animals to pull their carts full of merchandise. These working animals are machines down there, and to test their strength, their owners load weight onto the flimsy carts until the animals are close to collapsing. On the other hand, machines builders here treat their machines a lot better than street vendors treat these working animals.
