由于干冰可以用来保鲜食品，因此干冰近年来在食品行业非常受欢迎。然而，近年来干冰伤人的事件时有发生，这让不少商家和消费者对干冰的安全性产生了担忧。
The accident caused by dry ice
市民刘女士买了一个冰淇淋蛋糕。包裹里有几根小冰柱。刘女士将其装入矿泉水瓶中，与蛋糕一起放入冰箱。过了一会儿，突然一声巨响，原来是她家的冰箱门被炸开了。她这才发现，这些冰柱并不是普通的冰块，而是干冰，是干冰升华过程中释放出的大量气体。这些干冰在塑料瓶的密闭环境中爆炸。
Solve quality problems during dry ice production
How to solve the dry ice safety concerns? When producing dry ice for food, a high concentration of carbon dioxide must be used, which is a prerequisite for producing high-quality dry ice. However, there are harmful gases such as sulfur and benzene in carbon dioxide. Before making dry ice, purification is required to remove these impurities and achieve food-grade dry ice. Manufacturers must strictly control product quality and use high-quality raw materials and high-quality dry ice machines.
Increase market supervision
一些未经工厂部门批准的假冒企业也在生产干冰，这些干冰的质量没有保障，造成消费者上当受骗，危害消费者的健康。针对这种情况，相关部门需要加大对干冰市场的监督管理力度。
Enhance general knowledge of dry ice
Consumers and businesses who often use dry ice should learn more about some basic common sense. For example, dry ice must never be placed in a small airtight container, because the carbon dioxide generated when the dry ice sublimates cannot be discharged in time, and an explosion will occur. Also, dry ice should not be touched directly by hand. Because its temperature is extremely low, if you hold dry ice directly with your hands, it will cause damage to your skin instantly. You need to wear special gloves when you touch dry ice. A good way to store dry ice is to store the dry ice in a well-ventilated place, allowing the volatilized gas to be released naturally, or put it in a dry ice storage box.
