Question 797 Deck Safety

The correct answer is B) the speed of foam production is slower at lower water temperatures. The speed of foam production in a continuous-type chemical foam generator is directly related to the water temperature. At lower water temperatures, the chemical reactions that produce the foam are slower, resulting in a slower rate of foam generation. This is due to the fact that chemical reactions generally proceed more slowly at lower temperatures. The other answer choices are incorrect: A) Fresh water is typically used, but not exclusively. C) The amount of foam produced per pound of powder varies depending on the specific foam agent and equipment used. D) There is no universal maximum water pressure for chemical foam generators, as the appropriate pressure depends on the equipment design.
