What is the best method for detecting leaks in a CO2 system?

• A. Using a halide torch
• B. Applying soap and water
• C. Using litmus paper
• D. Monitoring temperature changes

Answer: (B)

The best method for detecting leaks in a CO2 system is by applying soap and water. This technique is effective because when soap is mixed with water, it creates a solution that can form bubbles when exposed to escaping gas. When applied to joints, fittings, or areas where leaks are suspected, any escaping CO2 will cause the soap solution to bubble up, indicating the presence of a leak. This method is not only simple and cost-effective, but it also provides a visual confirmation of the leak, making it easy for technicians to identify the exact location that requires further attention or repair. Other methods, while they may have their applications, do not offer the same level of ease and visual confirmation as the soap and water method. For instance, using a halide torch is more suited for refrigerant leak detection, and litmus paper is generally used for pH testing rather than gas leaks. Monitoring temperature changes might indicate a leak indirectly but does not provide a direct indication or location of a gas leak like the soap solution does.
