TOP TEN PERSONAL SAFETY

• Do not work alone.
• Wear non-conducting shoes.
• When working around A/C work with one hand in pocket.
• Never assume a system is safe to work on.
• Usually work with computers plugged in and monitors plugged out.
• Never wear jewelry.
• No loose clothing.
• Don't connect or disconnect peripherals when the system is on. (unless you have usb ports)
• Use only c, bc, or abc, fire extinguishers.
• Always discharge capacitors before touching.

REASONS WHY YOU SHOULD ABIDE THIS RULES.

• The reason you should not work alone is because you can get easily hurt and/or shocked and your computer can possibly catch on fire and a second person can help greatly.
• The reason you should wear non-conducting shoes is because conducting shoes keep electric static which could possibly fry your computer or yourself.
• Rule number three, is just because if the A/C shoots volts down through your body it should stop at the hand in your pocket will keep you insulated.
• Never assume a computer is safe to work on because a lot of the time it's not. If you follow all rules it should be safe though.
• The reason you should keep your computer plugged in is because most computer plugs have a third prong on it which is a ground and if volts do happen to shoot down the cord it will stop at the ground.
• Never wear jewelry, ESD (electric static discharge) and jewelry don't mix.
• Don't wear loose clothing because your clothes can get caught on something and could make it fall and/or break or something to that nature.
• Unless you have usb ports, you can fry the controller or slot if you plug the cord in or out while the computer is on.
• Notice that all the three different types of fire extenguishers have a "c" in them. This means that it will not hurt your computer because the c has some chemical in it that should keep your computer safe if you have to use a fire extinguisher on it.
• Capacitors can have 20,000 volts in them even if the computer is turned off!! Common sense says discharge first!

EQUIPMENT SAFETY

• Static mat .
• Wrist strap.
• Keep all components in anti-static bag.
• Individual chips should mount in a special non-static bag.
• Handle all parts by their edge. Do not touch metal parts or chips.

 

• You should always follow rules 1 and/or 2. If you do not, it's very possible that you could fry yourself or your computer.
• look at number 1)
• If you kept the part in an anti-static bag then when you insert it into your computer it should have no electronic charge and same goes for rule number 4.
• look up to rule number 3
• The reason for this rule is because 30 volts can fry a chip and you body can feel from 2,500 volts up. So you may fry a computer chip and it not even shock you.

You may not realize it, but your computer and your car have something in common: they both need regular maintenance. No, you don't need to change your computer's oil. But you should be updating your software, keeping your antivirus subscription up to date, and checking for spyware. Read on to learn what you can do to help improve your computer's security.

Getting started

Here are some basics maintenance tasks you can do today to start improving your computer's security. Be sure you make these part of your ongoing maintenance as well.

* Sign up for software update e-mail notices. Many software companies will send you e-mail whenever a software update is available. This is particularly important for your operating system (e.g., Microsoft VV!|VD0VV$® or Macintosh), your antivirus program, and your firewall.
* Register your software. If you still have registration forms for existing software, send them in. And be sure to register new software in the future. This is another way for the software manufacturer to alert you when new updates are available.
* Install software updates immediately. When you get an update notice, download the update immediately and install it. (Remember, downloading and installing are two separate tasks.) An ounce of prevention

A few simple steps will help you keep your files safe and clean.

* Step 1: Update your software
* Step 2: Backup your files
* Step 3: Use antivirus software and keep it updated
* Step 4: Change your passwords

Developing ongoing maintenance practices

Now that you've done some ground work, it's time to start moving into longer term maintenance tasks. These are all tasks that you should do today (or as soon as possible) to get started. But for best results, make these a part of a regular maintenance schedule. We recommend setting aside time each week to help keep your computer secure.

* Back up your files. Backing up your files simply means creating a copy of your computer files that you can use in the event the originals are lost. (Accidents can happen.) To learn more read our tips for backing up information.

* Scan your files with up to date antivirus software. Use your antivirus scan tool regularly to search for potential computer viruses and worms. Also, check your antivirus program's user manual to see if you can schedule an automatic scan of your computer. To learn more, read our tips for reducing your virus risk .

* Change your passwords. Using the same password increases the odds that someone else will discover it. Change all of your passwords regularly (we recommend monthly) to reduce your risk. Also, choose your passwords carefully. To learn more, read our tips for creating stronger passwords .

Making a schedule

One of the best ways to help protect your computer is to perform maintenance regularly. To help you keep track, we suggest making a regular "appointment" with your computer. Treat it like you would any other appointment. Record it in your datebook or online calendar, and if you cannot make it, reschedule. Remember, you are not only helping to improve your computer, you are also helping to protect your personal information.
