Which term describes a foam system designed to be moved and operated manually to different locations?

• A. Portable system
• B. Fixed system
• C. Mobile system
• D. Central system

Answer: (C)

Mobility defines the concept being tested: a foam system that can be relocated and used at different sites without being permanently installed. A mobile foam system is designed as a complete unit that can be moved from one location to another—often mounted on a cart, trailer, or similar platform—and operated manually at each new site. This distinguishes it from a fixed system, which is permanently installed and tied to a single location, and from a central system, which is a large, centralized supply rather than a relocatable unit. A portable system exists too, but it typically refers to smaller, hand-carried equipment rather than a full foam system that’s moved as a single unit to multiple locations. The key idea here is that the system is designed to be moved and operated manually across various locations, which is what makes it a mobile system.
