Clothing that is too loose should not be worn because it could interfere with the bungee cord. Accessories that could cause an injury if they fell off or came loose during a jump should be removed before jumping. Among these items are glasses, jewelry and contacts. Whether you are a beginner, advanced or professional bungee jumper, three-part classes that teach skills such as the inspection, testing and maintenance of harnesses as well as how to use slings, webbing and jump spaces are available. The parts of the classes are rescue training, bungee training and an apprenticeship period.
