Q

On small passenger vessels how many supply and exhaust ducts are required in each enclosed space containing gasoline powered machinery or gasoline fuel tanks?

🔍 Key Concepts

• 46 CFR Subchapter T requirements for small passenger vessels • Ventilation requirements for gasoline machinery and fuel tank spaces • Difference between supply ducts and exhaust ducts in enclosed spaces

💭 Think About

• Think about why gasoline vapors are dangerous and where they tend to collect in an enclosed machinery space. • Consider whether the regulation focuses on the number of ducts or the effectiveness of moving air in and out. • Ask yourself if the rule is aiming for redundancy (backup) or just basic minimum airflow.

✅ Before You Answer

• Check 46 CFR for the minimum required number of separate supply and exhaust ducts for each enclosed gasoline space. • Verify whether the requirement is the same number of supply ducts as exhaust ducts. • Confirm if the rule specifies more than one duct to ensure both intake of fresh air and removal of heavier-than-air gasoline vapors.
