Which method is commonly used for detecting ammonia leaks?

• A. Soap solution
• B. Ultrasonic detector
• C. Sulphur candle
• D. Infrared sensor

Answer: (C)

The method commonly used for detecting ammonia leaks is the sulfur candle. This technique involves burning a sulfur compound to produce sulfur dioxide, which reacts with ammonia to form a visible cloud that indicates the presence of a leak. The reaction is distinctive and, in the presence of ammonia, the sulfur candle creates a noticeable visual cue that can help operators identify the location and severity of the leak more effectively. While other methods like soap solution can provide some indication of leaks by forming bubbles, they are generally less effective for gases like ammonia, which can dissipate quickly into the atmosphere. Ultrasonic detectors can identify high-frequency sounds produced by leaks but may not specifically target ammonia leaks without additional context. Infrared sensors are effective for detecting certain gases, including ammonia, but they are typically more sophisticated and expensive compared to traditional sulfur candle methods. Thus, the sulfur candle remains a reliable and straightforward approach for ammonia leak detection.
