When rafting in white water, if you do not wear a life jacket (strongly not recommended), the safety risk will be greatly increased, because life jackets are the most critical equipment to prevent drowning. However, if due to special circumstances (such as damage to life jackets or emergency situations), the following measures need to be taken **To minimize the risk**： --- ### **1. Assess the environment and absolutely avoid high-risk waters** -**Choose gentle waters**: Only move short distances in still water or extremely slow rivers (no rapids, whirlpools, and rocks). -**Avoid whitewater level**: Do not try any waters with waves, turbulence or gaps (international standard Level I and above). -**Observe the water flow**: Stay away from obstacles (rocks, fallen trees), low temperature or muddy waters. --- ### **2. Teamwork and alternatives** -**There must be companions**: At least 2 or more people traveling together, and others need to wear life jackets and carry rescue equipment (such as rope throwing bags and buoyancy bags). -**Shore support**: Arrange for personnel to follow on the shore and be ready to rescue at any time. -**Emergency signal**: Agree on gestures or whistles to ensure that you can call for help quickly. --- ### **3. Alternative buoyancy tools (temporary emergency)** -**Use floatable items**: Hold on to waterproof bags, empty buckets, foam boards, etc. to increase buoyancy. -**Clothing inflation method**: Knot the feet of the trousers, quickly swing in the air and inflate and tighten the waist of the trousers (only for short-term emergencies, the effect is limited). --- ### **4. Body posture and self-help skills** -**Supine floating posture**: With your back facing down, spread your limbs to slow down sinking, and keep your mouth and nose above the water. -**Move along the current**: Avoid struggling against the current and move slowly towards the shore or slow-flowing area. -**Avoid obstacles**: Use your feet to detect forward to prevent being hit or stuck. --- ### **5. Strictly contraindicated** -**It is forbidden to act alone**: Floating alone without a life jacket is tantamount to life. -**Alcohol/drugs are prohibited**: Stay absolutely awake. -**Refuse bad weather**: Stop immediately when it rains, low temperature or poor visibility. --- ###**Important reminder** The International Whitewater Rafting Association (IRF) and all safety agencies **mandatory requirements**Life jackets (PFD) are essential equipment. The probability of drowning without wearing a life jacket is extremely high, and may lead to legal liability (such as violation of local water safety regulations). If the life jacket is lost or damaged, you should **Immediately terminate the activity** and seek help. Safety is always the first principle, so don't take risks by chance!
