Skating on lakes where the ice is gradually melting is extremely risky, and it is strongly recommended to avoid such behavior. However, if you have to try for special reasons, please strictly follow the following safety measures to minimize the danger.： --- ###**1. Absolute prerequisites** 1. **The thickness of the ice layer is at least 15 cm or more** (the strength of the ice layer decreases during the melting period, and it needs to be thicker than the conventional requirements). 2. **The temperature has been steadily below freezing for several consecutive days** (to avoid repeated melting and freezing of the ice due to the temperature difference between day and night). 3. **The ice surface must be uniform blue ice** (white, gray, or ice with cracks and bubbles is extremely unstable). --- ###**2. Risk assessment and preparation** 1. **Consult local agencies** Contact the forestry, fire protection or lake management departments to obtain official ice monitoring data and safety recommendations. 2. **Observe environmental warnings** - Avoid areas with water stains, cracks or significant thinning on the ice. - Stay away from the center of the river, aquatic areas, and rocks (the ice is easily weak). 3. **Prepare emergency equipment** -**Buoyancy equipment**: Wear a life jacket or carry a buoyancy bag. -**Crampons and ice picks**: Used to climb out of the ice cave. -**Life-saving rope** (more than 10 meters, knotted at both ends for easy grasping). -** Waterproof mobile phone ** + first aid kit + high-calorie food. --- ###**3. On-site operation guide** 1. **Team action** -At least 3 people walk together, keep a distance of 10 meters from each other, and connect with ropes. -Special personnel need to be left on the shore for observation and ready to call the police at any time. 2. **Dynamic detection of ice layer** -Use an ice pick to drill holes every 5 meters forward to measure the thickness. If the thickness changes by more than 20%, retreat immediately. -When you hear a "click” sound or feel the ice subsiding, quickly lean over and crawl to disperse your weight and evacuate. 3. **Shorten the residence time** Control it within 10 minutes to avoid the ice layer from continuing to soften due to body temperature or light. --- ###**4. Self-rescue in extreme situations** If you unfortunately fall into the water： 1. **Stay calm**, hold your breath to prevent choking. 2. **Hold the edge of the ice with both hands** to avoid crushing the edge of the ice with your body. 3. **Kick your legs and float**, roll your body horizontally away from the breach (do not stand). 4. Take off your wet clothes immediately after landing to prevent temperature loss, and seek medical attention for examination. --- ###**5. Alternative suggestions** 1. **Choose an artificial ice rink**: Indoor or professionally maintained outdoor ice rinks are safer. 2. **Use roller skating equipment**: Roller skating or skateboarding can simulate the skating experience in a safe venue. 3. **Postpone activities**: Wait for the ice to freeze again to a safe thickness in winter (usually -10℃ for more than one week). --- **Important reminder**: When the ice melts in spring, even if the surface seems solid, the bottom structure may have been honeycomb and the load-bearing capacity plummets. According to statistics, more than 80% of ice drowning incidents occur during the ice melting period. Life safety is much higher than entertainment needs, so don't take risks.
