When fighting a fire with a portable dry chemical extinguisher you should always _______________.
AI Explanation
The correct answer is D) direct the stream of chemical toward the base of the fire.
The reasoning behind this is that when using a portable dry chemical extinguisher, the goal is to cut off the fire's fuel supply by directing the chemical stream to the base of the fire. This allows the extinguishing agent to smother the fire and prevent it from spreading. The other options, such as bouncing the chemical or spraying across the tops of the flames, would be less effective at fully extinguishing the fire.
