Over time, people have figured out how thick ice should be in order to stand or skate on it - mostly by walking on it and seeing if they fall in. ;) I’ve seen a number of recommendations for exactly how thick it should be - some say 3 inches and some say 4. Just to be safe, wait for it to freeze to 4 inches. Also, be careful because the ice could easily be thick enough in one place and really thin just a few feet away. It can also get thinner or thicker over the course of just a few hours.
您应该始终让您了解溜冰的冰。如果是一个公共湖，请观看标志 - 应该有人定期检查并签名，以便每个人都知道。如果这是一个更私人的湖，永远不要独自滑冰。无论您身在何处，都要睁开眼睛，以了解任何裂缝，孔，树枝或其他危险事物。
