Question 54General Subjects - 1st Asst/Chief

The correct answer is D) "26". The device used to prevent over pressurization of the illustrated distiller is a pressure relief valve, which is typically labeled as item "26" in the diagram. Pressure relief valves are required by regulations to be installed on distillation systems to protect against excessive pressure buildup, which could be hazardous. The other options, "12", "13", and "19", do not serve this specific function of preventing over pressurization.
