What does dry ice do? Effects and hazards of dry ice

Function: fire fighting, used for artificial rainfall, as a refrigerant, cleaning up dirt on industrial equipment, used for food beautification, etc.

Hazards: Every time you touch dry ice, you must be careful and use thick gloves or other coverings to touch dry ice, if it is in direct contact with the skin for a long time, it may cause cell freezing and similar damage to minor or extremely severe burns. Dry ice should not be used in cars, cabins, etc., because the sublimated carbon dioxide will replace oxygen and may cause shortness of breath or even suffocation.

Dry ice is a solid carbon dioxide that is obtained by condensing carbon dioxide into a colorless liquid at a pressure of kilopascals, and then quickly solidifying it at low pressure. Nowadays, dry ice has been widely used in many fields.

The effects and hazards of dry ice are as follows:

Dry ice is at risk of frostbite if it is touched directly by hand; Volatilization in a sealed room, in the process of changing from a solid state to a gas, will increase the concentration of carbon dioxide in the space, and in severe cases, it will make people feel difficult to breathe; And placed in a closed refrigerator, it is very easy to cause**.

Although dry ice may bring losses to humans if it is not used and stored properly, dry ice itself brings a lot of convenience to human life. For example, dry ice is often used as artificial rainfall; It is often used to keep objects frozen or cold.

Because dry ice absorbs heat and sublimates into carbon dioxide gas, it has no residue, no toxicity, no peculiar smell, and has a sterilization effect, so it is widely used and has a large number of applications in food, health, industry and catering.

Precautions for the use of dry ice

1. Do not let children touch dry ice alone.

2. The temperature of dry ice is extremely low, do not put it in your mouth to prevent frostbite.

3. Be sure to use thick cotton gloves, clips and other masking materials when taking dry ice (plastic gloves do not have a barrier effect).

4. Please use dry ice in a well-ventilated place, and do not be in a confined space with dry ice.

5. Dry ice cannot be mixed with liquid.

Summary. Hello, dry ice is solid carbon dioxide with some special properties and uses. Its effects and harms are as follows:

Purpose:1Coolant:

Dry ice is quickly converted into gas when it comes into contact with air, releasing a large amount of cooling energy and can be used as a refrigerant. It is often used to keep food, medicine, and other perishable items cold. 2.

Dry Ice Smoke Effect: Putting dry ice in water produces a large amount of white smoke, which is often used in stage performances, special effects production, and chemical experiments. 3.

Cleaning and deodorization: Dry ice has the effect of sterilizing and removing odors. It can freeze and kill bacteria through direct contact or the smoke it produces, and adsorb odor molecules.

Hello, dry ice is solid carbon dioxide that has some special properties and uses for this. Its effects and hazards are as follows: Effects:

1.Coolant: Dry ice is quickly converted into gas when exposed to air, releasing a large amount of cooling energy and can be used as a refrigerant.

It is often used to keep food, medicine, and other perishable items cold. 2.Dry Ice Smoke Effect:

Putting dry ice in water produces a large amount of white smoke, an effect that is often used in stage performances, special effects production, and chemical experiments. 3.Cleaning & Deodorizing:

Dry ice has the effect of sterilization and odor removal. It can freeze and kill bacteria through direct contact or the smoke it produces, and adsorb odor molecules.

Hazards: 1Cryogenic burns:

Dry ice is at extremely low temperatures, and contact with ** or mucous membranes can cause low-temperature burns. Therefore, when handling dry ice, avoid touching it directly with your hands and instead use protective gloves or tools. 2.

High concentrations of carbon dioxide: Dry ice releases large amounts of carbon dioxide when it is rapidly converted into gas, and high concentrations of carbon dioxide can lead to hypoxia in confined spaces. Therefore, when using dry ice, Hongshou should ensure that the environment is well ventilated and avoid prolonged exposure to high concentrations of carbon dioxide.

In short, dry ice, when used and handled correctly, can play a special role. However, when using dry ice, it is important to pay attention to safety to avoid causing harm to the human body.
