Which type of solution can be used in conjunction with the back of your hand to find leaks within the boiler air casing?

• A. Alcohol
• B. Soapsuds
• C. Detergent
• D. Palm oil

Answer: (B)

Using soapsuds is an effective method for detecting leaks within the boiler air casing because the surface tension of the soap solution allows it to cling to surfaces and form bubbles when it comes into contact with escaping air. When the soapsuds are applied, if there is a leak, air escaping through the crack will create bubbles in the solution, making the leak visible. This method is simple, quick, and does not require any special equipment, which is why it is commonly used in maintenance and troubleshooting scenarios. Other options like alcohol, detergent, or palm oil may not provide the same visual indication of leaks. While some detergents could potentially show bubbles, soapsuds are specifically formulated for this purpose and are generally more effective due to their properties.
