Make it make sense…
I have a “water-reactive” chemical, and yet the IFC/IBC allows me to double my MAQ when the area is “sprinkled”.
d. Maximum allowable quantities shall be increased 100 percent in buildings equipped throughout with an automatic sprinkler system in accordance with Section 903.3.1.1. Where Note e also applies, the increase for both notes shall be applied accumulatively.
Then we see this in 415.8.3 Water reactive.
Group H-2 and H-3 occupancies containing water-reactive materials shall be resistant to water penetration. Piping for conveying liquids shall not be over or through areas containing water reactives, unless isolated by approved liquid-tight construction.
