🔍 Key Concepts

• 46 CFR Subchapter W (Lifesaving and Fire Protection) portable fire extinguisher requirements • The basic design purpose of a portable extinguisher versus semi-portable or fixed systems • How the Coast Guard defines "portable" in the context of fire equipment

💭 Think About

• Look at each choice and ask: which one describes a fundamental requirement for all portable extinguishers, regardless of size, type, or location? • Think about why an extinguisher is called "portable" and what minimum capability it must have to fulfill that definition in an emergency. • Consider whether the regulation would require every single portable extinguisher to work on a specific class of fire, or to be serviceable in a particular way, or something more basic.

✅ Before You Answer

• Verify which option matches the regulatory definition of portable, not just good practice. • Check if the requirement would apply equally to every type and size of portable extinguisher on board. • Be sure you are not confusing requirements for portable extinguishers with those for semi-portable or fixed systems.
