What is a disadvantage of using narrow angle fog while fighting fire?

Explanation:
Using narrow angle fog concentrates water into a tighter, directed pattern. That pattern cools flames effectively and can give quick knockdown, but it has a notable drawback in spaces that rely on Halon or high-expansion foam systems. The focused spray can disrupt or dilute the foam blanket and interfere with the distribution of clean-agent suppression, making this type of fog less effective when those systems are in play. In other words, while it cools fast, it can undermine the performance of Halon and HFP, which is why that option is identified as the disadvantage.
