In the absence of professional guidance, **It is not recommended** To try high-altitude bungee jumping for the first time (the safety risk is extremely high), but you still need to know the following key precautions to minimize the risk： --- ###**1. Strictly evaluate your own conditions** 1. **Health risks** -Prohibited groups: heart disease, high blood pressure, epilepsy, patients with spine/joint injuries, pregnant women, those who have not recovered from recent surgery, alcoholics or those who take psychotropic drugs. -**Potential danger**: Even if there is no medical history, a high-pressure environment may induce sudden physiological problems (such as arrhythmia). 2. **Mental preparation** -Panic may cause uncontrolled movements (such as wrong grasping of ropes or twisting of the body), increasing the risk of injury. --- ###**2. Compulsory inspection of sites and equipment** 1. **Refuse "wild bungee jumping”** -Only select bungee jumping sites with international certification (such as EBFA) to ensure regular mandatory testing of equipment (rope, buckle, elastic system life record). -Observe whether there are first aid equipment (such as AED) and professional rescuers at the scene. 2. **Ropes and equipment** -Confirm that the bungee jumping rope is a "dynamic rope” (ductility adapts to weight), not a static climbing rope. -Check the dual backup safety system (main rope + backup rope/pulley brake). --- ###**3. The life and death of security details are at stake** 1. **Must do before jumping** -Accurately measure weight (the error is less than ±2kg), and the equipment needs to match the elasticity coefficient according to the weight. -Repeatedly practice emergency gestures (such as using gestures for help when unable to shout). 2. **Jumping posture essentials** -**Fatal error**: Leg wrapped around the rope, head down into the water, reverse grip (may cause joint dislocation or rope entanglement). -Correct movements: cross your hands and hold your chest, and the ankle strap needs to be confirmed by others twice. --- ###**Fourth, emergency preparedness** 1. **Falling stage** -In case of abnormalities in the rope (such as excessive stretching/no rebound), immediately curl up into a ball to protect the head and neck. 2. **Bungee jumping on the water** -Touching the water is only allowed when the water depth is ≥5 meters and there is no vortex. The ankle strap must be unlocked before entering the water (to prevent drowning). --- ###**Ultimate suggestion** **Please be sure to give up the unguided adventure**! Even for professionals, bungee jumping for the first time requires training. You can first try indoor simulation bungee jumping (such as wind tunnel bouncing) or low-altitude bouncing rope adaptation. There is only one life, and professional guidance can avoid more than 90% of the hidden dangers of accidents.
