COMPUTER SAFETY

COMPUTER SAFETY•Hazards of working with a computer are divided into two areas:­physical; and­Psychological

•The piece of equipment which causes the most problems is the monitor.

Prepared by Rita K. Beardfor Business and Marketing Teachers in South Carolina

PHYSICAL PROBLEMS•Eye problems­The most severe eye problem in working with the monitor is eyestrain.­Some computer users suffer from eyestrain, blurred vision, and burning eyes.

What causes eye problems?

­Lighting conditions: ­less light is needed to operate computers.

­Windows create a glare on the monitor.

­Bright colors of walls.­Small fonts.­Improper machine maintenance.

ARE YOU AT RISK? • Working at the computer can cause problems such as:–eyestrain–persistent fatigue–back pain–tendonitis–Carpal Tunnel Syndrome

TIPS TO REDUCE EYESTRAIN

• Lower lighting level to: 1. reduce glare 2. improve screen contrast

• Place screen at right angle to avoid reflections and shadows

• Sit with ceiling fluorescent lights

parallel to your line of sight and to your side

PHYSICAL STRESS•Physical stress and eye problems are closely related because both problems are caused by poor design and improper use of equipment.

•Can cause back, neck, and shoulder pain as well as headaches and fatigue.

•Posture is very important to avoid physical stress and a serious medical condition later.

POSTURAL HAZARDS

•Certain postures are uncomfortable and hazardous to your health.

The following may lead to a serious condition:­Working with

inadequate back support­Head tilted back or forward­Shoulders hunched­Wrists bent­Feet unsupported

Reduce Sitting StressTHE RIGHT CHAIR HELPS TO REDUCE SITTING STRESS. YOUR WORK CHAIR SHOULD:• be fully height-adjustable;• support the lower back;• swivel easily;• have a separately adjustable back;• have a seat with a rounded front edge;• have five feet on castors; and• have adjustable arm rests.

Psychological Stress•Examples are:­Pressure of a supervisor watching you work.­Timed writings.­Fear of computers taking over jobs.­Fear of not making production.­Boring, repetitive tasks.

Prevent Eyestrain•Rest your eyes frequently by focusing on an object at least 20 feet away.

•Blink frequently.•Get regular eye exams.

PRACTICE GOOD SAFETY HABITS

•Is the top of your computer monitor at eye level? •Is the screen approximately 15-32 inches away? • Is the display sharp and steady?

PRACTICE GOOD SAFETY HABITS

•Is your field of view free from glare and reflections?•Do you have a document holder? •Are you using it?

PRACTICE GOOD SAFETY HABITS

•Are your wrists straight and horizontal to your work surface as you type?

•Are your feet flat on the floor?•Are your arms loose and comfortable at your side?

PRACTICE GOOD SAFETY HABITS

•Are you sitting back in your chair with your lower back well supported in its natural curve?•Is your backpack and jacket stored beside your chair - out of the walkway?

WORK – RELATED ACCIDENTS

WORKPLACE AND CLASSROOM ACCIDENTS

•Trips and falls are the number one cause of accidents in the classroom.•Falls are one of the most common accidents anywhere!

What Causes Falls?

•Floor wax, spilled soft drinks, anything wet or slippery on the floor!

•Worn spots on the carpet or chipped tiles.

•Pencils, paper clips, or other items on the floor.

Prevent Slipping and Tripping!

•Walk, never run in halls and classrooms.•Don’t change direction suddenly or stop quickly.•Choose shoes that fit, and tie your shoe laces.•Carry loads of reasonable size.•Keep aisles and walkways clear.•Good housekeeping is everyone’s job!

Chair Safety•Never lean back in a chair--you could do a “sitting back flip.”

•Never roll your chair around the classroom--you could do a “moving back flip.”

File Cabinets are Hazardous Too! •Major source of

office injuries! •Open only one drawer at a time.•Keep all heavy materials in the bottom drawer.•Beware of paper cuts!

Prepared by Rita K. Beardfor Business and Marketing Teachers in South Carolina

PAPER, BOXES, AND FILES……•Papers, boxes,

files...stacked...can result in an office landslide--be careful!

•Always store materials inside cabinets, files, and lockers--never on top!

Back Injuries•Use your leg muscles

NOT your back muscles to do

the work.•Don’t stoop......bend!•When you carry a load,

the usual procedure is to hold itin front of you at waist height and close to your body.

•Ask for help when the load is heavy.

Reaching High•Whenever you need to reach a height, use a stool or stepladder.

•NEVER stand on chairs, especially those with wheels!

Equipment Safety•Getting a finger caught in a piece of office equipment is no joke!

•Rings, bracelets, dangling necklaces, neckties, and loose shirt sleeves add to the hazard.

VIRUSES AND THREATS

COMPUTER VIRUSA program or programming code that replicates by being copied or initiating its copying to another program, computer boot sector or document. It attaches to another program or document (piggyback)

Computer Virus

Viruses can be transmitted as attachments to an e-mail note or in a downloaded file, or be present on a diskette, CD, or Flash Drive.

Types of Computer Viruses

Malware is software that has an evil intent. Some common types of malware are:

Adware puts ads up on your screen; Spyware collects personal information about you, like your

passwords or other information you type into your computer. Hijackers turn your machine into a zombie computer. These

hijackers can then control your computer to make it do what they want it to do.

Dialers force your computer to make phone calls. For example, one might call 900 numbers and run up your phone bill.

A hoax is something that is intended to deceive or defraud. An e-mail hoax is designed to appear to be true in order to defraud the recipient out of money or personal information.

COMPUTER THREATSBoot sector

Email Virus

Trojanhorse

Worm

Disk Killer

Boot Sector This virus disrupts

the booting up process of a computer or computer network and may prevent you from being able to use the computer.

Email Virus An e-mail virus travels as an attachment to e-mail messages and usually replicates itself by automatically mailing itself to dozens of people in the victim’s e-mail address book. Some e-mail viruses don’t even require a double-click to execute the small program file; they launch when you view the infected message in the preview pane of your e-mail software.

Trojanhorse A Trojanhorse is a computer program that claims to do one thing but instead does damage when you run it. For example, it may claim to be a game but may erase your hard drive. Trojanhorse have no way to replicate automatically.

Worm

A worm is a small program that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. Then, it copies itself to the new machine using the security hole and then starts replicating from there to another computer.

Disk Killer

This virus destroys (deletes or jumbles) the files on a hard disk, floppy disk, CD, or Flash Drive making the files unusable.

PROTECTING YOUR COMPUTER

METHODS OF AVOIDING VIRUS ATTACKS

• BROWSE SAFELY• AVOID CLICKING ON EVERYTHING

• BEWARE OF MISLEADING POP-UPS

• DON’T GO WHERE YOU’RE NOT SUPPOSED TO GO

•HANDLE DOWNLOADED FILES CAREFULLY• DOWNLOAD FROM TRUSTED SITES

• SCAN YOUR DOWNLOADED FILES

• DON’T’ OPEN ANYTHING YOU DON’T TRUST COMPLETELY

http://www.wikihow.com/Avoid-Getting-a-Computer-Virus-or-Worm

METHODS OF AVOIDING VIRUS ATTACKS•DEAL WITH EMAILS SAFELY

• DON’T OPEN EMAILS FROM SOMEONE YOU DON’T KNOW OR TRUST.

• DON’T DOWNLOAD ATTACHMENTS FROM SOURCE YOU “DON’T” KNOW OR “DO” KNOW UNLESS YOU ARE EXPECTING IT.

• PROTECT YOURSELF• INSTALL ANTIVIRUS SOFTWARE

• INSTALL ANTI-SOFTWARE PROGRAM

• ENABLE FIREWALLS

• KEEP WINDOWS UPDATED

• BE CAREFUL WITH USB DRIVES

• BE WARY ABOUT REMOTE ACCESS

• KEEP A GOOD BACKUP

Once a virus has been detected, you can have your virus protection software “fix” the problem. In some cases, you may have to take your computer to a qualified computer technician to remove the virus and “repair” your computer.
