So in that building there's a nonflammable reactant that's super dangerous to life and reacts with water, and a flammable chemical that is quite toxic.
So... Bring my HEV suit and crowbar?
They're waiting for you, OP, in the test. Chamberrrr.
OP doesn't need to hear this. OP's a highly trained professional.
Depends, are you in the tank today?
What's interesting is they could have made one compound NFPA diamond that encompasses the worst ratings of everything in the building instead of two individual diamonds. The primary intent of these on buildings is to inform first responders of what they might be rushing into.
One diamond might give conflicting or incorrect info if there's several things that would react to logically correct answers when firefighting. Last thing you need is to start a reaction when everything is already on fire because while it lists one reactant, it supercedes another reactant that would have been displayed on a secondary diamond.
