70% to passYour vessel is carrying a cargo of Propionitrile, which has caught fire. Which extinguishing agents should be used?
AAlcohol foam, water fog, or dry chemical.
BAlcohol foam, carbon dioxide or dry chemical.
CWater fog, carbon dioxide or dry chemical.
DAlcohol foam, carbon dioxide, or water fog.
AI Explanation
The correct answer is B) Alcohol foam, carbon dioxide, or dry chemical. Propionitrile is a flammable, polar solvent that requires extinguishing agents that are effective on both ordinary combustible fires and fires involving polar solvents. Alcohol foam, carbon dioxide, and dry chemical are all suitable for this purpose. Water fog may not be as effective on a polar solvent fire. The other options, while generally effective for many fire types, do not provide the optimal combination of agents for a propionitrile fire.
