Dry ice is a refrigerant obtained by directly converting carbon dioxide gas into a solid under high pressure. It has several applications: 1. Frozen Food and Pharmaceuticals: Dry ice is widely used for the transportation and storage of frozen food and pharmaceuticals. Due to its low temperature and rapid cooling speed, it can effectively maintain the freshness and quality of food and medicines. 2. Special Effects and Stage Performances: Dry ice is also extensively used in special effects and stage performances. When it comes into contact with environmental heat, it rapidly converts into gas, producing a large amount of white smoke, creating a mysterious and dramatic atmosphere. 3. Cleaning and Disinfection: Dry ice can also be used for cleaning and disinfection. When it comes into contact with surfaces, due to the drop in temperature and the physical impact of the vaporization process, it can effectively remove dirt, bacteria, and viruses without leaving residues. 4. Laboratories and Scientific Research: Dry ice is also applied in laboratories and scientific research. It can be used to freeze samples, create low-temperature experimental environments, and make cold traps and condensers, among others. It is important to note that safety should be observed when using dry ice, avoiding direct contact with skin and eyes, and not using it in enclosed spaces to prevent the accumulation of carbon dioxide, which can lead to oxygen deficiency.

If a leak in the CO2 storage tank is detected, the following steps should be taken immediately: Confirm the leak location: First, determine the exact location of the leak, which can be done through hearing, observation, or using gas detection equipment. Emergency response: Upon discovering a leak, take immediate emergency measures to ensure personnel safety. Evacuate personnel to a safe area and notify relevant personnel and emergency agencies. Cut off the gas supply: Quickly shut off the CO2 supply source by closing valves or cutting off power to stop the supply of CO2. Locate the leak: In a safe environment, use gas detection equipment or visual inspection to find the leak. Apply soap solution or other leak detection agents to potential leak areas and observe for bubbles. Seal the leak: Once the leak location is identified, take temporary sealing measures using tape, sealant, or other reliable sealing materials for temporary repair. Ensure the sealing is secure and effective in preventing gas leakage. Repair and maintenance: In a safe condition, carry out further repairs and maintenance as needed. Depending on the nature of the leak, it may be necessary to replace seals, repair or replace valves, etc. These repairs should be conducted by trained personnel. Inspection and testing: After repairs, perform leak detection and testing to ensure the leak has been fully repaired and the tank's safety performance has returned to normal. It is important to handle CO2 storage tank leaks with caution and follow relevant safety regulations and procedures.
