1.1 Bungee jumping as it pertains to this standard is an activity where a participant (jumper) is connected to a bungee cord and harness system and, when directed jumps or falls from a height from a designated jump point. The jumper then descends via gravity until the elastic bungee cord starts to stretch, slowing the descent until stopping by reaching the maximum stretch of the bungee cord for the jumper’s weight and velocity at which point due to the elastic properties of the bungee cord, the jumper will then move upward. This process repeats itself until the jumper’s vertical position stabilizes after which the jumper is moved to a location where the bungee cord system is removed, and the activity is completed.
1.2 In this practice, criteria are established for the design, manufacture, construction, installation, integration, operation, maintenance, auditing, and modifications of a bungee jumping site for the primary purpose of amusement that occur(s) after the effective date of publication of this practice except as noted in 1.3.
1.3 This practice shall not apply to:
1.3.1 Bungee jumps from helicopters and hot air balloons;
