Final answer:
The halide torch is not the most effective method for checking small leaks. Other methods like soap bubble testing or gas detectors are more accurate and effective.
Step-by-step explanation:
The statement that the halide torch is the most effective method for checking small leaks is false.
A halide torch, also known as a gas leak detection torch, is primarily used to detect larger gas leaks. It works by burning a mixture of hydrogen gas and a halide-containing compound that emits light when it comes into contact with a gas leak.
However, for detecting small leaks, other methods such as soap bubble testing or gas detectors that use sensors and alarms are more accurate and effective.
