How do you smoke test for vapor leak?

To perform a smoke test for vapor leaks, you can use a smoke-generating device or a smoke pen to introduce smoke into the area or system being tested. Seal off any openings to ensure the smoke remains contained, then observe for any escaping smoke, which indicates a leak. It’s essential to conduct the test in a controlled environment, ensuring safety precautions are in place, especially if flammable vapors are present. This method is effective for quickly identifying leaks in various applications, including HVAC systems, piping, and containment areas.
