Skating on thin, untested ice is extremely dangerous and is strongly recommended to be avoided. Thin ice may not support a person's weight, resulting in plunging into icy water, which may result in serious injury or life-threatening consequences. If you need to walk or skate on ice, the following safety measures are recommended: 1. **Test the thickness and strength of the ice**: Before entering the ice, make sure the ice is at least as thick as the safety standard. Generally, at least 4 inches (about 10 cm) of transparent blue ice is considered sufficient to support the weight of an adult. But this standard is just a guide and actual conditions may vary. 2. **Wear appropriate safety equipment**: Wear a life jacket and bring ice fishing tips (or ice picks) to help you save yourself in a possible accident. 3. **Travel with a companion**: Never skate alone. Having a companion by your side can help in an emergency. 4. **Carry a cell phone and rope**: Keep your cell phone fully charged and in a waterproof bag so that you can call emergency services when needed. Bringing a long rope may come in handy when rescue is needed. 5. **Pay attention to weather and temperature changes**: Ice is affected by the weather, and fluctuations in temperature may cause changes in ice strength. It is a good idea to check the weather forecast before going out. 6. **Know the waters**: Before engaging in ice activities, it is best to understand the terrain and water depth conditions in the area. In addition, avoid estuaries, rapids, and places where underwater objects may exist, as ice in these areas is often unstable. It is always beneficial to follow the above safety tips, but the safest practice is always to completely avoid activities on ice that has not been confirmed to be safe.
