Which statement about leakage tolerances is true?

• A. Open systems leakage tolerance is Not acceptable; Closed systems leakage tolerance is Unacceptable
• B. Open systems leakage tolerance is Acceptable; Closed systems leakage tolerance is Not acceptable
• C. Open systems leakage tolerance is Seepage acceptable; Closed systems leakage tolerance is Weepage acceptable
• D. Open systems leakage tolerance is Weepage acceptable; Closed systems leakage tolerance is Seepage acceptable

Answer: (A)

Leakage tolerances boil down to whether any leakage is permissible in a system. In this context, leakage is not acceptable for either an open system or a closed system. For an open system, seepage or any escape to the surrounding environment undermines safety, containment, and environmental controls, so it’s not tolerated. For a closed system, leakage breaks containment, risking loss of pressure, contamination, and safety hazards inside the system. Because maintaining integrity means preventing leakage in both scenarios, the statement that leakage is not acceptable for either type is the correct one. The terms seepage and weepage describe how leakage might occur, but they don’t make leakage acceptable in any system.
