Which statement best describes Class 2 leakage?

• A. Seepage not forming drops
• B. Seepage of fluid great enough to form drops but not great enough to cause the drops to fall during inspection
• C. Seepage that forms droplets that drip during inspection
• D. No seepage present

Answer: (B)

This item tests how leakage is categorized by what you can visually observe during inspection. Class 2 leakage means you can see seepage that has formed small drops, but those drops do not fall off during the inspection window. It sits between seepage that only dampens a surface (no drops) and leaks that show active dripping during inspection, which would indicate a more severe condition. You’d typically address this level of leakage to prevent it from worsening, rather than treating it as an immediate, catastrophic failure. If seepage doesn’t form drops, that’s milder and requires less urgent action; if droplets actually drip during inspection, that’s more severe and calls for faster corrective steps. If there’s no seepage at all, there’s nothing to address.
