Production of mechanical foam by a portable in-line foam proportioner _______________.
AI Explanation
The correct answer is D) gives the nozzleman more freedom of movement, since it can be placed anywhere in the hose line.
A portable in-line foam proportioner allows the nozzleman to position the foam proportioning device anywhere along the hose line, rather than being limited to a fixed location. This provides the nozzleman with greater flexibility and mobility when applying the foam, as they can adjust the position of the proportioner to optimize the foam application. The other options are incorrect because a portable in-line proportioner does not directly affect the size of foam bubbles, the rate of foam production, or the extinguishing properties of the foam.
