Exam Question

### (a) Tanker Pump Room Ventilation
Pump rooms on tankers are designated as hazardous zones due to the high probability of cargo vapor accumulation. Effective ventilation is a critical safety measure mandated by SOLAS to maintain the atmosphere below the Lower Explosive Limit (LEL) and ensure a safe working environment.
**System Design & Operation:**
* **Type:** The ventilation system must be a mechanical, power-operated system of the **exhaust type**. This creates a negative pressure within the pump room, ensuring that any vapor leakage is contained and extracted, preventing its spread to non-hazardous areas like the engine room.
