🔍 Key Concepts

• 46 CFR Subchapter T requirements for small passenger vessels • Differences between foam, dry chemical, and CO₂ extinguishers (what classes of fire they cover) • How the regulations treat "approved" portable fire extinguishers on inspected vessels

💭 Think About

• Think about whether the Coast Guard limits inspected vessels to just one or two extinguisher types, or if it focuses on whether each unit is approved and suitable for the class of fire • Ask yourself: do small passenger vessel rules exclude any of these common extinguishing agents, or mainly require that they be of the proper type, size, and approval • Consider how many different hazards (fuel, electrical, rubbish) are on a typical small passenger vessel and which extinguishers can safely handle them

✅ Before You Answer

• Verify in 46 CFR 181 (Fire Protection), especially the section on portable extinguishers for small passenger vessels • Check whether each listed extinguisher type (foam, dry chemical, CO₂) appears as an approved type in the regulations • Confirm that the rule is about "permitted types" rather than a single "required" type only
