Skating on ice that is melting and no longer feels safe is very risky. The thickness of ice is often uneven, and melting ice may form weak areas somewhere, which can easily lead to sudden cracks in the ice and cause dangerous accidents. The following suggestions are for reference, but please note that even if all precautions are taken, the risk cannot be completely eliminated: 1. Know the ice conditions in advance: Before considering ice activities, be sure to pay attention to local weather, temperature and ice condition reports. It is best to consult local management departments or experienced professionals to confirm whether the ice is safe enough. Generally speaking, personal activities are only suitable when the ice is at least 4 inches (about 10 cm) thick and has been professionally tested to confirm safety. 2. Check the uniformity of the ice: Even if the overall ice seems thick enough, there may be local thin areas. Survey the skating area in advance and try to choose a skating area that has been tested, fixed and publicly certified for a long time. 3. Go with a group: Never skate alone. It is best to go with a partner and make sure that at least one person has first aid knowledge. If conditions permit, it is best to have someone carry a communication tool to contact rescue personnel in an emergency. 4. Equipped with life-saving equipment: Wearing life jackets, helmets and other protective equipment can provide a certain amount of buoyancy and protection in case the ice cracks and falls. In addition, you can carry emergency auxiliary equipment such as ropes, ice drills, and crampons. 5. Control the scope of activities: Try to move in known safe areas and pay attention to changes in the ice surface at any time. When you find that the ice surface becomes soft or fluctuates, stop the activity immediately and stay away from possible dangerous areas. 6. Exit in time: When there is sufficient sunlight or the temperature rises, the ice layer will melt further. Be careful to choose to carry out activities when the weather is relatively stable and the temperature is low. In general, skating on a lake where the ice surface is gradually melting is extremely dangerous. If the stability of the ice surface cannot be fully guaranteed, it is recommended not to try ice activities. Safety always comes first. Choosing a skating venue that has been tested and publicly licensed is the best way to ensure your own safety.
