🔍 Key Concepts

• 46 CFR Subchapter T requirements for ventilation on small passenger vessels • Difference between supply ventilation and exhaust ventilation in gasoline machinery spaces • Why gasoline vapor hazards require mechanical exhaust rather than relying only on natural ventilation

💭 Think About

• Which type of ventilation is most effective at removing heavier‑than‑air gasoline vapors from the lowest part of an enclosed space? • Does the regulation focus more on supplying fresh air to the space, or on exhausting flammable vapors from the space? • Is a simple opening to the outside sufficient to control gasoline vapor buildup in an enclosed machinery/fuel tank space?

✅ Before You Answer

• Verify in 46 CFR that gasoline engine or fuel tank compartments require exhaust ventilation from the lowest part of the space • Check whether the rule specifies mechanical vs natural for supply and exhaust separately • Confirm if an option that only provides an opening without active exhaust meets the gasoline vapor ventilation requirement
