It is imperative that the surface you are jumping from is tall enough to allow for a long fall. Most people jump from bridges that have water underneath them or from cranes operated by companies for the purpose of bungee jumping. Crane jump landing pads are often lined with thick mats. Whether it be water or mats, it is a smart move to have something pliable to break your fall in case of emergency. It is best to make sure that your gear and jump site are rigged by safety professionals.
