this module, We're gonna go over safety procedures related to PCs and laptops
so working with I t equipments and especially Petey PCs for personal computers.
Uh, yes. D is one of the biggest things we have to be aware of. Electric static discharge, its cause from building electricity, of static electricity from walking across things like carpets and that electric six that elect electro static
discharge can destroy computer parts. They're very sensitive to that.
So we want to be very careful of protecting our PC equipment from
electrostatic discharge. So So the prevention tools we can use to protect our equipment is any static wrist strap
What they do is they ground it. They ground us so that they don't build up stack electricity that can transfer
So here's an example of an anti stack wrist strap.
So you put this around your your wrist and attach the metal clip to something that's grounded like the case of the PC.
And so, while you're working, you don't have. If you did have any
static electricity, you would have discharged and you won't develop any static electricity while you're working on the PC parts. So it's considered very good practice for all professionals when they're working on PC parts or electronics toe wear one of these.
Another very common was the anti stack Matt.
This reforms kind of the same function,
but without the bracelet. So, uh, when you're not working with the parts and you have the part sitting on a workbench or something, just have it sitting on one of these mats to avoid
So you want to avoid risk from what it's just sitting at. Rest if it's sitting right on the metal of a table and then you touch the table in the table has
a stack, which you have with static electricity transferred through table and could pry the park. But this will ensure that it's safe when it's not in the case.
Ah, any stack tools utilize resisters to prevent the static charge or static buildup
so you could test them with the multi meter to make sure the resisters still working to help
like if you're gonna have it off the table out of the computer for a while, your PC components of your parts,
or you're gonna actually store them for extended period time. You should keep them in
anti static bags like the one here. They're really cheap.
If you work in I t stuff. If you look if you work in, I t repair frequently.
Most new parts come in one, so you should always save
save the ones you have. I know I do a lot of my team PC maintenance and I have stacks of these things. So just if you don't throw, just never throw it away when you get it. When you get by new parts and usually find one laying around somewhere hard drive's coming. Um, everything comes in when they're shipped from the manufacturer. They're also really cheap to buy online. If you if you don't have any,
but you should be storing, you should store all your electronic parts and
Another thing to be concerned about. His electromagnetic interference from the magnetic field interfere with electronic functionality. It's less dangerous than JST, but undamaged parts like hard drives and Sieroty motors,
so, like heavy so I wouldn't have a microwave right next to your desktop.
especially hard drives of racist tips of *** EPT susceptible. Tiu, am I, um
so have magnets near those.
Or if I radio frequency interference is ah, very common one that's low, hard to protect against but doesn't really cause permanent damage. It just caused interference.
So because we're dealing with frequencies and way stronger frequency frequencies, broadcasting on a stronger wave are gonna interfere with other stuff. So, like Marco waves and, uh,
Cordless phones will interfere with your wife. I so don't try to try to use those apart from each other than they can also interfere with cell phones.
try to keep devices. They're wireless, separate from each other unless they're using the same technology.
My grades were just bad for everybody
again. Doesn't cause damage. Just disrupt service.
This watch, we will talk about personal safety in terms of PC maintenance and operation
cables are probably one of our worst enemies, and I t
especially when we're fixing parts and working in a lab environment because we're not gonna have the cables all nicely run behind a desk or we're not gonna have.
They're all coming into a nice network. Jack on the side of the wall if we're working on multiple pieces at once while power supplies and power cables running everywhere and network cables running everywhere, which would come tripping hazards something to be aware of.
Okay, what should be placed behind walls or any cable runs and behind
computer cases utilize patch panels. And when you're setting up switches and routers and a permanent solution?
not only does it help you easily troubleshoot your cables because they're all nicely organized, but you know less chance of being a tripping hazard.
Don't be running your network cables when you said, but just stop running your network cables and power supplies across the floor
when the computer parts air heavy. I mean, just the parts supply alone is probably the heaviest part of a desktop. But then you start adding the hard drives and especially dealing with Sierra team owners and servers.
Lifting can be there's a lot of heavy objects. So when dealing with heavy objects moving them around, make sure that you pay attention if it's still in the box and we usually tell you, Okay, minimum of two people to lift minimum of four people left. I'll show you where to lift, especially some of the servers that Iraq mounted very heavy and also UPS is
be aware of the requirements and how many are you? Don't think
when in doubt, you should get another person to do it cause serious back injuries. Remember, toe pick up with your knees, not your back.
So instead of bending over to pick up squat down with your knees,
uh, available a hand truck can help. Also,
this important when I've seen this happen before, too. So when when mounting stuff and racks are stacking stuff for computer equipment, be aware of how heavy it is I've seen. If you're gonna put something in Iraq, make sure the heavier stuff on the bottom
and on the top, because the heavier stuff on the top could not only fall down on this stuff behind it, but top heavy and ah at the top Heavy will also have a greater chance of it. Tipping over this could apply to just stacking boxes but also stacking network equipment in Iraq.
Make sure that the item isn't too heavy to be held in Iraq, sir, and racks have a weight limit, so should be you should check the instructions or the manuals.
Eso computers get very, very, very hot. So if you're working on
computer one, make sure you turn off shelves for wait a few seconds after you turn off before you go Removing parts
course after you've already moved the power supply, the parts get extremely hot. So just like checking the stove, you should wave your hand over it before touching it. See? Okay. Does this feel hot? Just like checking a stove before you actually go touching some of these parts. I know I've been a little too eager sometimes and
gun messing with a hard drive or something right after I've turned off. Whoa,
that's that's toasty.
do as I say, Not as I do. I learned the hard way.
Uh, also, a lot of these computer parts will warn you that
they will heat out. They'll have stickers on this, eh?
Careful there. Gets hot when running.
We're actually working on the computers, especially on desktops. Make sure you don't have anything that could get caught. I mean, like, you should take off any rings you have,
especially if the computer's running while you're like checking so you haven't turned on. You got everything together and you always put the cover on the case last. Because
if you don't, there's something not gonna work. So you have your new PC altogether. You fixed it, so you plug it in. You can put the case on. There's a lot of fans and stuff moving in there. You know, you lean over, you know, if your hair's not pulled back, you have long hair could get caught. You have a necklace on. You could get caught in the fan or
could get caught in a cable, and you lift up and it pulls it out while the machines running.
You're gonna have a bad time.
