Such work includes ensuring that the bungee cord is anchored properly and other equipment, including airbags, is used as needed. For a safe jump, it is essential that the bungee cord is tied off in a secure location, one that is stable and will not be affected by added weight. Steel railings or safety fences often make good places from which to anchor. Professionals also will make sure that the bungee cord is tied with weight-bearing knots that will stay in place when gravity is pulling jumpers downward. In some locations, companies may place airbags, webbing or slings at the bottom of a jump space to guarantee the safety of jumpers. For inexperienced jumpers, locations with airbags and webbing can provide a safer place to start. Some companies may call off jumps due to inclement weather: Equipment may not work properly in rain, snow and other types of weather. Poor visibility and unstable wind conditions also increase the risk of injury.
