What is electrocution?
|
Examples: |
|
Electrocution is caused by electricity passing through your body. |
|
|
Don't use exposed electrical wires. |
|
|
Keep drinks away from electrical equipment. |
|
|
Never open up an electrical device. |
|
# |
Most ICT devices require an electrical power source.
|
# |
Whenever you have electrical power sources you run the risk of the electrocution.
|
|
Electrocution is harm, or even death, caused by an electric current
passing through the body. |
|
# |
The main causes of electrocution along with prevention strategies are listed in the table below: |
|
Causes and prevention of electrocution: |
Cause |
Prevention |
Faulty equipment (bare wires etc). |
Make sure wires are insulated.
|
Spilling drinks over electrical equipment.
|
Keep drinks away from equipment.
|
Using malfunctioning or faulty equipment |
Report any malfunctioning equipment to a technician.
(Don't use it!)
|

ICT devices require power from a mains outlet.
|
Examples: |
|
Don't overload plug sockets. |
|
|
Have a fire extinguisher in the room. |
|
|
Keep vents clear to allow air circulation and prevent overheating. |
|
# |
If too many devices are plugged into a single mains at the same time it is possible to overload the circuit and start an electrical fire.
|
#
|
You need to ensure that your room has many plug sockets so you don't have to overload any single one.
|
# |
The main causes of fires along with prevention strategies are listed in the table below: |
|
Causes and prevention of fires: |
Causes |
Prevention |
Too many devices plugged into a single mains outlet. |
Make sure that your room has plenty of mains outlets.
|
Leaving devices plugged in unattended for long periods.
|
Don't plug too many devices into the same outlet. |
Covering air vents on devices like laptops.
(This can cause the device to overheat and start a fire)
|
Turn off and unplug devices if you are going to be away for a long time. |
Have a CO2 fire extinguisher at hand to quickly put out any fires that start. |
Make sure that air vents on devices are uncovered to allow free air circulation. |

ICT devices with wires can make a room a potential hazard.
|
Examples: |
|
Trailing wires trip people and cause injury.
|
|
|
Cable covers are used to encase loose wires and prevent tripping. |
|
|
WiFi allows devices to operate without wires and removes the possibility of tripping over them. |
|
# |
Trailing wires are easy to trip over if they are not secured or tucked away.
|
# |
Tripping over wires can lead to falling to the ground and breaking bones, ligament strains etc.
|
|
Causes and prevention of tripping over wires: |
Causes |
Prevention |
Long wires or cables trailing across a floor. |
Encase the wires in cable covers.
(Cable covers are pieces of plastic or rubber that are used to encase wires) |
Tuck trailing wires under desks or carpets.
|
Use wireless technology to eliminate the use of wires altogether. |

Some ICT devices (like computer screens) are fairly heavy and can cause injury if they fall on you.
|
Examples: |
|
Falling equipment can cause physical injury. |
|
|
Position equipment well away from edges. |
|
|
Use a sturdy desk which can take the weight of the equipment and has plenty of space. |
|
# |
Equipment should be positioned securely on strong desks and tables well away from the edge.
|
|
Causes and prevention of falling equipment: |
Causes |
Prevention |
Equipment not positioned securely onto desks. |
Make sure that equipment is positioned away from the edge of desks. |
Poor quality and flimsy desks. |
Make sure that the desk has plenty of space. |
Use strong desks/tables that can support the weight with ease. |
