question #5\nmultiple choice\nwhat other feature do class b foams and dry chemical possess to aid in the suppression of jet - fu\nthey increase volatility of the fuel.\nthey require different hoses and nozzles.\nthey are more cost - efficient.\nthey decrease flammability of the fuel.
Answer
Brief Explanations:
Class B foams and dry - chemical agents are used to suppress jet - fuel fires. Their main purpose is to reduce the fire - causing properties of the fuel. Increasing volatility would make the fuel more flammable, different hoses and nozzles are not related to the suppression mechanism, and cost - efficiency is not a feature related to fire suppression. Decreasing the flammability of the fuel helps in suppressing the fire.
Answer:
They decrease flammability of the fuel.
