🔍 Key Concepts

• 46 CFR Subchapter I requirements for portable and semi-portable extinguishers on cargo/miscellaneous vessels • Characteristics of a Class B fire (what is burning, and what agents are effective) • Minimum sizes/types of extinguishers (foam, dry chemical, CO₂) that are accepted as hand portable or semi-portable under the regulations

💭 Think About

• For each listed extinguisher type, ask yourself: Is this agent suitable for flammable liquids (Class B), and is this size normally considered portable or semi-portable? • Consider whether the CFR usually treats different agents (foam vs dry chemical vs CO₂) differently in terms of minimum capacities for Class B coverage. • Think about whether the regulations tend to approve only one specific type/size here, or recognize multiple types/sizes as meeting the same Class B capability.

✅ Before You Answer

• Check in 46 CFR Subchapter I tables that show extinguisher types and sizes for Class B fires on cargo vessels. • Verify for each option whether it is explicitly listed as a hand portable or semi-portable extinguisher size (not fixed system or too small). • Confirm that the agent in each option (foam, dry chemical, CO₂) is actually listed as acceptable for Class B protection in those tables.
