Unit 8-Safety and Sequrity
Health risks with using IT
Problem
Back and neck problems/strain (caused by sitting in front of a computer screen for long periods in the same position)
soloution
use fully adjustable chairs to give the correct posture
use foot rests to reduce posture problems
use screens than can be tilted to ensure the neck is at the
correct angle
problem
Repetitive strain injury (RSl)-damage to fingers and wrists caused by continuous use of a keyboard or repetitive clicking of mouse buttons
soloution
ensure correct posture is maintained (i e , correct angle of arms to
the keyboard and mouse, for example)
make proper use of a wrist rest when using a mouse or a keyboard
take regular breaks (and do some exercise)
make use of ergonomic keyboards
use voice-activated software if the user is prone to problems when
using a mouse and keyboard
problem
Eyestrain caused by staring at a computer screen too long or having incorrect lighting in the room
soloution
ensure that there is no screen flicker as this can lead to eye problems
change to LCD screens where flicker is less of a problem than with
CRT screens
take regular breaks (and try focusing on a point that is some
distance away)
make use of anti-glare screens if lighting in the room is incorrector or use window blinds to reduce sunlight reflecting from the screen;
users should have their eyes tested on a regular basis (middle vision glasses should be prescribed if the user has a persistent problem such as eye strain, dry eyes, headaches, etc.)
problem
Headaches caused by incorrect lighting, screen reflections, flickering
screens, etc
soloution
use an anti-glare screen or use window blinds to cut out reflections (incorrect lighting can cause squinting and lead to headaches)
take regular breaks (and do some exercise)
have your eyes tested regularly and use middle vision glasses if
necessary
problem
Ozone irritation caused by laser printers in an office area (dry skin,respiratory problems, etc )
soloution
proper ventilation should exist to remove the ozone gas as quickly
as possible
laser printers should be housed in a designated printer room
change to other types of printer if necessary (e g , inkjet printers)
safety risks of IT
Electrocution
soloution
use an RCB (residual current breaker)
. check insulation on wires regularly
. don't allow drinks near computers
. check equipment on a regular basis
Trailing wires (trip hazard)
soloution
use cable ducts to make the wires safe
. cover wires and/or have them neatly tucked away (under desks, etc.)
. use wireless connections wherever possible, thus eliminating cables altogether
Heavy equipment falling and
causing injuries
soloution
use strong desks and tables to support heavy hardware
. use large desks and tables so that hardware isn't too close to the edge where it can fall
Fire risk
soloution
have a fully tested CO2ldry fire extinguisher nearby (not water extìnguishers)
. don't cover equipment vents (causing equipment to overheat)
. make sure that the electrics used in the hardware is fully maintained
(i.e portable appliance testing)
. ensure good ventilation in the room (again to stop overheating of
hardware)
. don't overload sockets with too many items
. change to low-voltage hardware wherever possible (e.g., replace CRT
monitors with LCD monitors)
checks on a regular basis
checks on a regular basis
check the state of the wires/cables and plugs (check whether any wires/cables
are damaged, make sure there are no lose wires in the plugs and make sure
the plug isn't broken or cracked)
make sure that drinks (such as tea or coffee) are well away from the computer
fix wires along walls and behind desks wherever possible to remove the risk of
wires coming into contact with people
don't cover computers with paper or fabric (e.g., towels or sheets) since these
can either block ventilation holes (causing computers to overheat) or these
materials could catch fire
don't plug too many devices into an electric outlet socket - overloading a
socket can cause a fire
make sure you exercise every hour or so to prevent the health risks
carry out an 'ergonomic assessment' on your work station
minimise the impact of
sitting in front of screens or typing for long periods at a time.
buy new chairs or computer hardware
E-Safety
definition
It refers to safety when using the internet, i.e . keeping personal data safe and applies to any of the following devices:
devices
mobile phone
. computer or tablet
. games console
wireless technology.
personal data
Personal data refers to any data concerning a living person who can be identified
either from the data itself or from the data in conjunction with other information
egsamples
personal data examples
name
address
date of birth
medical history
banking details.
Some personal data is often referred to as sensitive personal data and includes:
examples
ethnic origin
political views
religion
sexual orientation
criminal activity.
rules to follow online
don't give out any personal information to people who are unknown to you; this
is especially true online where it isn't possible to physically meet people so that
their motives can be firlly assessed. Remember that anyone can say anything they
want online and it is very difficult to determine whether they are genuine or not
o don't send people photos of yourself - either online or via a mobile phone
unless the person is known to you (it is very easy for somebody to pass
more rules
drese photos on or even pretend to be you for a number of reasons); this is a
particularly large risk on social networldng sites
o always maintain your privacy settings on whatever device is being used online
or during cornmunications. Privacy settings allow the user to control which
cookies are stored on their computer or they enable the user to decide who can
view certain information about them on, for example, a social nenvorking site
o when accessing the internet make sure the websites being visited can be trusted two common ways of checking this is to look for https or the padlock
more rules
when using search engines, always make sure the device settings are
set to 'safe search' and the highest possible level of security is used
o only use websites recommended by teachers and only use a learner-friendly
search engine
o only open emails from known sollrces. It is always a good idea to make sure
your internet service provider (ISP) has an effective email filtering feature to
ensure unknown emails are placed in the spam box
o only email people you know. Think carefully before opening arry ernail and
never include the school's name or photos of a student wearing a school
uniform in any email
o it is extremely important to be vigilant when using social networhing sites,
instant messaging or chat roofiìs:
. block or report anybody who acts suspiciously or who uses inappropriate
language
o be very careful with the language used in ch.at roorns
. always use a nickname and nrperyortr real name
keep private and personal data secret
. don't enter private chat rooms - stay public (the danger signs in a private
chat are: somebody sounds too good to be true, they ask you to go to
instant messaging and then to emails, they request your telephone number
and then finally slrggest that you meet)
. never arrange to meet anyone for the first time on your own
. always tell an adult first and meet the person in a public place
. avoid the misuse of images
. always use appropriate language
o always respect people's confidentiality.
with online gaming
risks
violence in the game itself, which can lead to violent behaviour in reality
o predators (people who prey on others who they see as vulnerable)
o cyber bul\,i¡g (the use of electronic communication to bully a person)
typically by sending messages of an intimidating or threatening nature)
o use of webcams (the risks here are obvious)
o voice-masking technology (to disguise a voice so you can't tell their sex or
age) or even their accent)
o it is often overlooked that online games are also a solÌrce of cyber attacks
on a user's computer or mobile phone - viruses, phishing or spyware are
well-reported examples of problen'rs associated with certain online gaming.
