When discharging a portable CO2 fire extinguisher, you should NOT hold the horn of the extinguisher because the horn _______________.

A is placed directly in the flames
B could come off in your hands
C becomes extremely hot
D becomes extremely cold
AI Explanation

The correct answer is D) becomes extremely cold. When discharging a portable CO2 fire extinguisher, you should not hold the horn because it becomes extremely cold due to the rapid expansion and evaporation of the CO2 gas. Holding the cold horn could cause frostbite or other cold-related injuries. The other answer choices are incorrect - the horn is not placed in the flames, it does not come off, and it does not become extremely hot.
