WEBVTT 1 00:00:00.240 --> 00:00:02.160 In this lesson, we're going to talk about 2 00:00:02.160 --> 00:00:04.530 some safety procedures that you should be aware of 3 00:00:04.530 --> 00:00:06.900 as you begin working as a technician. 4 00:00:06.900 --> 00:00:08.880 Now, if you're following along in this course 5 00:00:08.880 --> 00:00:09.780 and you want to try to build 6 00:00:09.780 --> 00:00:11.820 your own custom personal computer, 7 00:00:11.820 --> 00:00:14.070 then it's going to be very important that you consider 8 00:00:14.070 --> 00:00:15.630 your own personal safety 9 00:00:15.630 --> 00:00:17.430 as you perform the different actions 10 00:00:17.430 --> 00:00:19.710 that I'm going to perform in these videos. 11 00:00:19.710 --> 00:00:21.510 There are four main areas of safety 12 00:00:21.510 --> 00:00:22.770 that you need to consider 13 00:00:22.770 --> 00:00:24.690 when you're working as a technician. 14 00:00:24.690 --> 00:00:27.120 Personal safety, component safety, 15 00:00:27.120 --> 00:00:29.850 electrical safety, and chemical safety. 16 00:00:29.850 --> 00:00:31.980 First, we have personal safety. 17 00:00:31.980 --> 00:00:34.260 Now, everything we're going to talk about in this video 18 00:00:34.260 --> 00:00:36.300 could be considered personal safety 19 00:00:36.300 --> 00:00:38.040 because we want to prevent injuring ourselves 20 00:00:38.040 --> 00:00:39.120 when we're working. 21 00:00:39.120 --> 00:00:41.880 But really for the topic of personal safety, 22 00:00:41.880 --> 00:00:44.130 you need to focus on avoiding trip hazards, 23 00:00:44.130 --> 00:00:46.110 utilizing proper lifting techniques, 24 00:00:46.110 --> 00:00:48.450 and using safety goggles and masks. 25 00:00:48.450 --> 00:00:50.580 Avoiding trip hazards is an important step 26 00:00:50.580 --> 00:00:53.610 to ensuring your safety and the safety of your coworkers. 27 00:00:53.610 --> 00:00:56.100 A trip hazard occurs anytime you have an object 28 00:00:56.100 --> 00:00:58.410 in the pathway where people are going to walk. 29 00:00:58.410 --> 00:00:59.910 Most commonly, this occurs 30 00:00:59.910 --> 00:01:01.560 when a technician runs a power cable 31 00:01:01.560 --> 00:01:03.450 or a network cable across the floor 32 00:01:03.450 --> 00:01:05.220 from an outlet or a wall jack 33 00:01:05.220 --> 00:01:07.950 into a desktop computer or workstation. 34 00:01:07.950 --> 00:01:10.260 To prevent people from tripping over these cables, 35 00:01:10.260 --> 00:01:12.900 you should always run cables through your drop ceilings, 36 00:01:12.900 --> 00:01:14.460 underneath your raised floors, 37 00:01:14.460 --> 00:01:17.520 or you should use a cable runway that covers the distance 38 00:01:17.520 --> 00:01:20.430 across the floor to prevent people from tripping. 39 00:01:20.430 --> 00:01:22.140 Anytime you're working on a desktop 40 00:01:22.140 --> 00:01:23.670 or other piece of equipment, 41 00:01:23.670 --> 00:01:26.190 make sure you don't put that equipment or components 42 00:01:26.190 --> 00:01:29.220 in the pathways that people normally are walking as well. 43 00:01:29.220 --> 00:01:30.840 Always clean up after yourself 44 00:01:30.840 --> 00:01:33.000 to ensure that people don't trip over any garbage 45 00:01:33.000 --> 00:01:34.440 or old components that you left out 46 00:01:34.440 --> 00:01:36.120 when working on a system. 47 00:01:36.120 --> 00:01:37.800 Another personal safety item 48 00:01:37.800 --> 00:01:40.890 is to follow and utilize proper lifting techniques. 49 00:01:40.890 --> 00:01:43.710 Whenever you attempt to lift a heavy or bulky object, 50 00:01:43.710 --> 00:01:45.930 you can injure your back or strain your muscles 51 00:01:45.930 --> 00:01:47.280 if you aren't careful. 52 00:01:47.280 --> 00:01:49.320 So if you're lifting a heavy object, 53 00:01:49.320 --> 00:01:51.960 always lift with your legs and not your back. 54 00:01:51.960 --> 00:01:53.640 This means you should bend your knees 55 00:01:53.640 --> 00:01:56.100 to lower yourself down and grab that object, 56 00:01:56.100 --> 00:01:58.710 instead of bending over at the waist to pick it up. 57 00:01:58.710 --> 00:02:00.780 If the object is too large, bulky, 58 00:02:00.780 --> 00:02:03.810 or heavy to carry yourself, you can ask a coworker 59 00:02:03.810 --> 00:02:05.820 or buddy to be able to buddy lift it 60 00:02:05.820 --> 00:02:07.800 or buddy carry that object with you, 61 00:02:07.800 --> 00:02:11.310 or use a push cart to move the object from place to place. 62 00:02:11.310 --> 00:02:13.830 If the object is over 40 to 50 pounds, 63 00:02:13.830 --> 00:02:15.900 you should probably have someone help you lift it 64 00:02:15.900 --> 00:02:19.470 because we consider this a two-person or team lift. 65 00:02:19.470 --> 00:02:21.720 Now, the next personal safety item we're going to use 66 00:02:21.720 --> 00:02:24.720 is safety goggles, gloves, and masks. 67 00:02:24.720 --> 00:02:26.610 When working around certain components, 68 00:02:26.610 --> 00:02:28.680 you may be using chemical compounds, 69 00:02:28.680 --> 00:02:31.110 such as thermal paste when installing a processor, 70 00:02:31.110 --> 00:02:33.690 or compressed air to clean out a piece of equipment. 71 00:02:33.690 --> 00:02:36.600 In these cases, you always need to use safety goggles 72 00:02:36.600 --> 00:02:38.820 to prevent anything from going into your eyes, 73 00:02:38.820 --> 00:02:41.640 gloves to prevent the chemicals from getting on your skin, 74 00:02:41.640 --> 00:02:44.220 and masks to ensure you don't breathe in those chemicals, 75 00:02:44.220 --> 00:02:46.290 dust or other particulates. 76 00:02:46.290 --> 00:02:48.300 The second area of safety for us to consider 77 00:02:48.300 --> 00:02:50.220 is known as component safety. 78 00:02:50.220 --> 00:02:52.050 Now, component safety includes the actions 79 00:02:52.050 --> 00:02:54.420 that you're going to take to prevent damaging the components 80 00:02:54.420 --> 00:02:56.010 that you're going to be working with. 81 00:02:56.010 --> 00:02:59.100 The biggest threat to your component is known as ESD, 82 00:02:59.100 --> 00:03:01.230 or electrostatic discharge. 83 00:03:01.230 --> 00:03:02.730 Now, electrostatic discharge 84 00:03:02.730 --> 00:03:04.890 occurs when a path allows electrons 85 00:03:04.890 --> 00:03:06.960 to rush from a statically charged body 86 00:03:06.960 --> 00:03:09.180 to a component that doesn't have a charge. 87 00:03:09.180 --> 00:03:12.240 So if you've just walked across a carpeted floor, 88 00:03:12.240 --> 00:03:15.240 you're going to be building up static electricity in your body. 89 00:03:15.240 --> 00:03:18.180 And then if you touch a motherboard, an expansion card, 90 00:03:18.180 --> 00:03:19.500 or other circuit board, 91 00:03:19.500 --> 00:03:21.570 you can actually discharge that static electricity 92 00:03:21.570 --> 00:03:24.870 from your body into that component and it will damage it. 93 00:03:24.870 --> 00:03:27.330 To prevent ESD from damaging your components, 94 00:03:27.330 --> 00:03:29.040 you should always carry your components around 95 00:03:29.040 --> 00:03:32.220 in an antistatic bag that protects it from ESD 96 00:03:32.220 --> 00:03:34.230 by using a coating inside of that bag 97 00:03:34.230 --> 00:03:36.150 that is a conductive material. 98 00:03:36.150 --> 00:03:39.030 This prevents static electricity from discharging from you 99 00:03:39.030 --> 00:03:41.220 through the bag to the component. 100 00:03:41.220 --> 00:03:42.150 Now, when it comes time 101 00:03:42.150 --> 00:03:44.190 to handle the components for installation, 102 00:03:44.190 --> 00:03:46.590 you're going to need to wear an ESD wrist strap 103 00:03:46.590 --> 00:03:48.300 that discharges the static electricity 104 00:03:48.300 --> 00:03:50.550 from your body into a ground. 105 00:03:50.550 --> 00:03:52.620 And this prevents an electrostatic discharge 106 00:03:52.620 --> 00:03:54.990 from going into the components instead. 107 00:03:54.990 --> 00:03:57.300 Now, as I demonstrate working with the different components 108 00:03:57.300 --> 00:03:59.130 to build a computer in this course, 109 00:03:59.130 --> 00:04:01.200 you're going to see me using antistatic bags 110 00:04:01.200 --> 00:04:03.780 to carry the components, an ESD wrist strap 111 00:04:03.780 --> 00:04:04.917 when I handle those components, 112 00:04:04.917 --> 00:04:08.430 and an ESD mat that holds the computer and the components 113 00:04:08.430 --> 00:04:11.670 when I go to install the components into a given system. 114 00:04:11.670 --> 00:04:13.830 The third area of safety for us to consider 115 00:04:13.830 --> 00:04:15.570 is known as electrical safety. 116 00:04:15.570 --> 00:04:18.870 Now, our computers, servers, printers and other equipment 117 00:04:18.870 --> 00:04:21.540 all rely on electricity to function properly. 118 00:04:21.540 --> 00:04:24.000 To protect yourself from the threat of electrocution, 119 00:04:24.000 --> 00:04:25.650 you should always unplug the computer 120 00:04:25.650 --> 00:04:27.990 prior to working inside of its case. 121 00:04:27.990 --> 00:04:30.360 For example, if you're going to install more memory 122 00:04:30.360 --> 00:04:32.040 or replace an expansion card, 123 00:04:32.040 --> 00:04:33.930 you should fully shut down the computer, 124 00:04:33.930 --> 00:04:37.440 unplug the power cord, and then go to work on the system. 125 00:04:37.440 --> 00:04:40.200 Additionally, when you connect a computer or other equipment 126 00:04:40.200 --> 00:04:42.180 to a power outlet, you should always ensure 127 00:04:42.180 --> 00:04:44.220 that your equipment is properly grounded 128 00:04:44.220 --> 00:04:46.680 and that the equipment is plugged into a surge protector 129 00:04:46.680 --> 00:04:48.450 to prevent damage to your equipment 130 00:04:48.450 --> 00:04:50.460 during a high voltage event. 131 00:04:50.460 --> 00:04:52.650 The fourth area of safety for us to consider 132 00:04:52.650 --> 00:04:54.450 is known as chemical safety. 133 00:04:54.450 --> 00:04:56.460 Now, as part of your job as a technician, 134 00:04:56.460 --> 00:04:58.260 you're going to come across various hazardous 135 00:04:58.260 --> 00:04:59.880 and chemical materials. 136 00:04:59.880 --> 00:05:01.710 Now, in addition to wearing protective gear 137 00:05:01.710 --> 00:05:03.780 like goggles, gloves, and masks, 138 00:05:03.780 --> 00:05:05.730 you also need to know how to properly handle 139 00:05:05.730 --> 00:05:08.490 and dispose of hazardous materials and chemicals. 140 00:05:08.490 --> 00:05:11.760 This includes lithium batteries, toner from laser printers, 141 00:05:11.760 --> 00:05:14.940 hazardous materials and components such as lead, mercury 142 00:05:14.940 --> 00:05:17.100 and arsenic, and many others. 143 00:05:17.100 --> 00:05:18.870 For each chemical or hazardous material 144 00:05:18.870 --> 00:05:20.370 that you work with in your job, 145 00:05:20.370 --> 00:05:23.130 you should have access to a material safety data sheet 146 00:05:23.130 --> 00:05:26.430 known as the MSDS, which contains all the information 147 00:05:26.430 --> 00:05:29.310 about the ingredients, health hazards, precautions, 148 00:05:29.310 --> 00:05:31.980 and first aid information for that given chemical 149 00:05:31.980 --> 00:05:34.860 or hazardous material that you're going to be working with. 150 00:05:34.860 --> 00:05:38.040 So remember, when it comes to working with computers 151 00:05:38.040 --> 00:05:40.080 and handling different components and equipment 152 00:05:40.080 --> 00:05:42.210 that you're going to see me using in this course, 153 00:05:42.210 --> 00:05:44.460 always take the proper safety precautions 154 00:05:44.460 --> 00:05:47.520 to prevent injuring yourself, others, or your equipment 155 00:05:47.520 --> 00:05:50.760 by following the proper personal safety, component safety, 156 00:05:50.760 --> 00:05:53.553 electrical safety, and chemical safety procedures.
