An electrical hazard is something with the potential to cause injury, illness or death.
When we think of electrical hazards, shock and electrocution would be two dangers
we immediately consider. Although these are important to guard against, there are
two other electrical hazards:
• Fire.
• Burns.
To help understand and locate problem areas in using electricity, both at work and at
home, some common electrical hazards and their potential dangers are explained
below.
Overloaded Power Sockets
If more electricity is pulled through the outlet than the wires are equipped to handle,
then the outlet is overloaded. With an overloaded electrical wire, too many electrons
move through the wire at once generating resistance, as a result, the wire heats up,
and a hot wire can start a fire.
Most overloading situations are caused by putting too many electrical plugs into one
outlet. This is made possible by using multi-outlet adaptors, or "octopus connections".
These multi- outlet adaptors could be regarded as the main problem for causing most
fire and electrocution incidents.
The use of multi-outlets adaptors should be discouraged. If there are more plugs than
outlets, ask an electrician to evaluate the radio room wiring system. The electrician
may suggest adding more outlets or upgrading the wiring. If a multi-outlets adaptor
is to be used, use one which meets the appropriate safety standard.
Extension Power Outlets
The major reason for using an extension power outlet is because there are no
convenient wall socket outlets near the electrical equipment. This is acceptable if the
equipment is used on a temporary basis. The extension power outlet must be of a safe
type, and the extension cord should be arranged to prevent tripping. Extension power
outlets are often of the multi-outlet design. If this is the case, similar precautions as
mentioned above for "adaptors" should be observed.
