Seepage is considered acceptable under which condition?

• A. When it forms a pool
• B. In operation with no pooling
• C. Only during maintenance
• D. Never acceptable

Answer: (B)

Seepage is the slow escape of liquid through seals or joints. In operation, a small amount of seepage is tolerated only if it does not collect and form a pool. A pool means liquid has accumulated to a standing surface, which creates slip hazards, fire risk, and potential environmental damage. When seepage remains as a non-pooling condition, it can be monitored, contained, or drained as part of normal operation. Therefore, seepage is considered acceptable during operation as long as no pooling occurs.
