WEBVTT 00:00.140 --> 00:07.290 Find work well if there's one thing that's guaranteed to reduce the availability of your I.T. systems 00:07.470 --> 00:08.220 it's fire. 00:08.220 --> 00:12.400 So in this episode I want it covered just a little bit of fire suppression. 00:12.420 --> 00:16.650 Now when we talk about fire suppression that's really going to be in two very different ways. 00:16.650 --> 00:22.690 Number one it wouldn't be a county exam without some discussion of fire extinguisher classes. 00:22.740 --> 00:27.780 And then secondly I want to talk about fires and fire suppression within the server room. 00:27.780 --> 00:33.990 So first of all let's go through the different classes of fire extinguishers different types of fires 00:34.020 --> 00:36.240 the different classes of fire extinguishers. 00:36.240 --> 00:44.010 So first we have what's called a Class A a class A fire extinguishers designed for ordinary solid combustibles 00:44.010 --> 00:51.220 like burning wood a class B fire extinguishers designed for flammable liquids and gases. 00:51.220 --> 00:57.250 So if you worked at the gasoline station you'd probably have a class B fire extinguisher laying around. 00:57.250 --> 01:04.010 Number three is a Class C Class C fire extinguishers are designed for energized electrical equipment. 01:04.090 --> 01:08.410 So if you're working with electrical equipment you need class the fire extinguishers. 01:08.500 --> 01:13.110 Class D is for combustible metals which even sounds scary for me to even think about. 01:13.210 --> 01:19.960 And then Class K K is for kitchens that's for oils and fats So guess which type of fire extinguisher 01:19.960 --> 01:25.710 you need to suppress a fire in your server room or with any type of computer equipment. 01:25.720 --> 01:26.220 That's right. 01:26.240 --> 01:28.780 Class classy Kesey's worked out pretty good. 01:28.780 --> 01:32.800 The only downside to a class C is when you shoot them they fire out a lot of powder. 01:32.800 --> 01:36.850 They can be pretty messy but they're really good at stopping electrical fires. 01:36.940 --> 01:40.900 OK let's move over to the server room now and talk about what happens in there. 01:40.990 --> 01:45.490 The server room is going to be filled with absolutely critical systems. 01:45.490 --> 01:48.020 So what we want to do here is we want to put out a fire. 01:48.070 --> 01:48.910 Absolutely. 01:48.940 --> 01:53.040 But if we can do it without destroying equipment that would be a very good thing. 01:53.050 --> 01:59.410 So using water for example or a classy fire extinguisher with its corrosive powder could be a pretty 01:59.410 --> 02:00.910 pretty bad thing. 02:00.910 --> 02:05.190 So what we do is we look for alternative fire suppression materials. 02:05.320 --> 02:08.280 Now for decades we use something called Halan. 02:08.380 --> 02:11.000 So Halon was a great fire suppressor. 02:11.000 --> 02:16.120 The only problem was it was not even slightly environmental friendly and we haven't seen it for many 02:16.120 --> 02:17.530 many many years. 02:17.530 --> 02:25.450 Today the gold standard for fire suppression in server rooms is a type of material called F.M. 200 F.M. 02:25.450 --> 02:28.350 200 does a great job at suppressing fires. 02:28.420 --> 02:30.760 Yet on the same token it won't destroy equipment. 02:30.820 --> 02:34.260 And on top of that it won't mess with the environment also. 02:34.330 --> 02:36.400 So suppressing the fire is important. 02:36.400 --> 02:41.090 However there's other things to think about within the server room like for example you should seal 02:41.110 --> 02:42.400 off the server room. 02:42.460 --> 02:48.600 Now in a well-designed HVAD system the server room is all ready probably pretty well sealed. 02:48.670 --> 02:50.220 So that's not a big deal. 02:50.230 --> 02:57.540 However and this is where we tie into the H-back system what we'll do is often tie the H-back into a 02:57.540 --> 03:03.180 fire suppression system so it'll simply shut the louvers and knock down the Atri a c. 03:03.240 --> 03:08.520 So all of that if I'm 200 isn't sucked out of the room and vented out someplace. 03:08.580 --> 03:13.110 The other thing we need to remember is we have to turn off the power and this can be a tricky one. 03:13.110 --> 03:18.600 And again this is why we tie our fire suppression to our H-back systems because we want to be able to 03:18.600 --> 03:22.310 bring down the systems in such a way that we don't totally destroy them. 03:22.350 --> 03:27.270 But it has to be done very very quickly so that we can suppress the fire. 03:27.270 --> 03:27.870 All right. 03:27.870 --> 03:34.260 So again when it comes to fire suppression as far as I'm concerned I'm going to go out and get good 03:34.260 --> 03:41.460 vendors who provide me good fire suppression systems and also remember for the exam FM 200 is the magic 03:41.460 --> 03:58.860 stuff.
