Dry ice can be used to take pictures and create a feeling of fairyland, and it is also often used in stage performances. In addition, although the visual effect of dry ice is excellent, the human body must not touch it easily, and it is very easy to be burned by cold. This is because the temperature of dry ice is very low, which is worse than human body 100 degrees. Once burned, it will be more serious than being burned by boiling water. Therefore, we must be very careful when dealing with dry ice. Safety is the most important thing.
Matters needing attention in using dry ice
Remember, every time you touch dry ice, you must be careful to touch it with thick cotton gloves or other shelter. If it is in direct contact with the skin for a long time, it may cause cell freezing and similar mild or extremely severe frostbite.
Dry ice cannot be used in sealed places such as cars and cabins, because the sublimated carbon dioxide will be denser than oxygen, so oxygen will be squeezed out, which may lead to shortness of breath and even suffocation.
