🔍 Key Concepts

• Fire extinguisher class and size ratings for flammable liquid fires (Class B vs Class A ratings) • Specific 46 CFR fire protection requirements for tank barges engaged in transfer of Grade B flammable liquids • Difference between requirements for fixed systems and hand portable extinguishers on unmanned tank barges

💭 Think About

• Which extinguisher rating (A or B) is intended primarily for flammable liquid fires on the deck/cargo tank area of a tank barge? • Does the presence of a fixed fire-extinguishing system in the cargo pump area usually remove the need for hand portable extinguishers, or are both often required by regulation? • For an unmanned, cargo pump-equipped tank barge of about this size, does the regulation specify more than one hand portable extinguisher in the cargo tank area, or only a minimum single unit?

✅ Before You Answer

• Verify in the CFR table that applies to unmanned tank barges with cargo pumps transferring Grade B flammable liquids. • Check which class and size of extinguisher is required in the cargo tank/pump area (look for B-II or equivalent modern rating like 40-B:C). • Confirm whether the regulation explicitly states that no hand portables are required when a fixed system is installed, or if hand portables are still mandated.
