All right, so here's one, "Why do fire sprinklers have different color systems for the bulb than the color code?" I'm not 100% sure what that part of the question means, but I just want to focus on the idea of the color system for the bulb.
That's the actual little part of the sprinkler head that gives off, where it breaks open and the water actually comes out. So the thing to say here is there are a lot of different types of sprinklers. There's sprinklers that...for example, in a server space, in a computer room, I wouldn't want to have a water-based sprinkler system. Obviously it would trash all the servers, and the whole point of that room is to protect the servers. It's probably only one or two people in there.
So you would use a system that would be some sort of chemical-based system that the whole point is actually to take away the oxygen. So that's a different kind of sprinkler system. Most places, the individual heads are going to go off when there's a problem, but in certain places, you might find it, when there's a problem anywhere, all the heads go off. So that would be in a place like...the usual classic examples are like a hangar that has expensive airplanes in it. They just don't want to take the chance that one fire would get out of control, there's all that fuel around, things like that. So all the heads would go off all at once.
Those are deluge systems. There's lots of different kinds of systems of sprinklers. But even within each of those systems, there are different temperature ratings. So you can imagine that if you're in, let's say, an office building, and in that office building there was a big mechanical room, or like the elevator mechanical room, something like that, a little machine room, where in that one spot, they're...or sometimes for various reasons, you get a spike of heat, but it's not really a spike of heat that is meaningful. It's not actually saying there's really a problem, then you wouldn't want to use a sprinkler head that went off at the same heat level as you would in the ones that are just in a general office space.
In a general office space, if I get a spike of heat of 180 degrees or something like that, well, that's really hot, and that means something weird is happening, and you want something to respond. Whereas if I'm in the elevator machine room, actually I'm making this up, I'm not sure about elevator machine room, but something, a place like that that generates a lot of heat and it has systems for dissipating it. But you could easily have something, at the end of an event, and suddenly the elevators are all getting used constantly, and it generates some unexpected level of heat, but it dissipates out and it's actually okay.
So there are different kinds and they're color coded for the level of heat they can tolerate before they would go off. I wouldn't worry about it beyond that. I don't think you need to memorize the specific colors. Feel free if you want to. I certainly haven't and won't. There's no huge advantage. That's a level of detail that's just going to start to drive you crazy. If they ask you that very specific question, and I know it's easy for me to say it, I say guess and move on. I say guess red maybe. I think red is always a good one to guess in that situation.
Because it's not just worth memorizing that kind of stuff, but it's sort of interesting to know that that exists, that there are different types, but then there's also different temperature ranges within each type, and that makes sense. You wouldn't want to have a commercial kitchen have the system go off at the same temperature as you would in a bedroom or in an office space or something. Because a commercial kitchen, you could easily imagine spikes of heat that would be inappropriate in those other spaces. Okay, so real quick on some of these other things.
Also, one of the just while it's worth noting here, most of the time when you are walking through a building and you see all the exposed mechanicals, you can always tell the basic sprinkler pipes because they're unpainted. So there tend to be black pipe. Different locations possibly might have slightly different rules about that, but generally all the ones I've seen, it's always that they don't want you to paint the pipes and that they use black pipes. That's so that the fire marshals, when they're walking through the building, they can very easily and quickly see everything, they can test it easily, they don't get lost, like they have a lot of stuff to cover.
