Electrical Accident:
n electrical incident is an event resulting from either personnel action or
equipment failure involving electrical installations that has the potential to
result in an injury due to:
1) Electrical flash and/or burn,
2) Electric shock from a source greater than 50Vac or 100Vdc,
or
3) Reflex action to an electric shock
Real electric shock may cause anything from a light tingle to a prolonged illness,
to sudden death. But it may also merely startle the victim who then loses his
balance and is injured by a fall.
In accidents not involving a shock, electricity may, or may not, be the cause of a
fire.
An accident involving electricity may be due to an illegal installation or to an
unsafe use or to an improper act by the victim.
An accident may be due to a superficially correct but negligent installation.
1. Classification of electrical Accidents:
In general electrical accidents may be classified as Fatal and non-fatal to human
beings, fatal to animals and fire accidents. Both fatal and non-fatal electric
accidents involve departmental as well as non-departmental persons.
As a pre-requisite the department of electrical inspectorate investigates and
reports the possible causes for occurrence of Electrical accidents.

Page 75 of 81
By refering to the above reasons it can be inferred that majority of non-
departmental accidents are occured in connection with 11KV & LT distribution
network of supplier.
Number of accidents were resulted due to carrying of Iron
rods/Aluminium Pipes etc., near the overhead LT & HT lines.
Major accidents were reported due to snapping of LT conductor,
grounding of electric poles, guy wires, spiral earthing etc. due to leakage of
current.
Next to this, majority of electrocutions reported due to repairing of live
electric equipments like motor, household equipments Iron box, mixer grinder,
etc., since consumer is not having much knowledge about the equipment, when he
himself repairs/ works on the live electric household equipments, eventually it
leads to an hazard.
Public shall be educated in this regard through mass communication
systems like TV, Radio, News papers by telecasting sponsored programs viz Tele
films, documentary films, short clippings on safe and secure use of Electricity
& Electricity related hazards.
Also electrocutions / incidents have been reported in connection with
serial set lighting installation. Since loose wires, skinned out wires are used for
temporary lighting during festivals and these temporary wires are wired on
metal surfaces like grills, gate, etc. due to leakage in such wiring there is a more
increased chances of hazards. Also in some cases GI wire used to support the
service cables/wires used for temporary serial set, lighting installation are used
as neutral for return supply.
And also procession carrying idols in habitat area, arch and any metal decorative
parts may come in contact with overhead lines and possibly many people might
have electricuted by this type of incidents.
There is a need to educate public especially in rural village areas to take
precautionary measures during festivals.
And also proper grounding, using of ELCB/RCCB for AEH installation, etc.
Periodical maintenance / checking the instruments soundly for any leakage will
avoid many accidents. By publishing dos & don’ts on use of Electricity, educating
consumers on safe handling of electricity/electric equipments, regular, thorough
maintenance of distribution network and replacing & repairing of all the
accessories connected with LT distribution network like jungle clearances,
tightening of loose contacts in lines, reduction of sag in line, action to avoid
overload of the over head conductor , replacement of old & deteriorated
Page 76 of 81
overhead conductors, providing proper protection system like fuses/ MCCB’s on
secondary side of the transformer and make it ready for rainy /monsoon season
will reduce 50 to 60% of Non-departmental accidents.
During rainy seasons more number of lines will likely to be snapped,
insulators puncturing will result, up keeping of LT network during rainy season
will minimize such accidents.
Next, other major accidents resulted by unauthorized energisation of
fencing.
Since many farmers to safe guard their crops from wild animals,
unauthorizedly energize the fencing provided to their field. By this, people and
animals unknowingly have come in contact with the unauthorized energized
fencing and got electrocuted. Many animals like elephants have also died due to
contact with unauthorized energized fencing.
And also it is noticed that majority of the electrical accidents have occurred
due to clear violation of particular rules of IE Rules, 1956 such as

14. Major Electrical Accidents Occurred in the State of Karnataka
during 2011-12
1. Fencing around the sheep
yard was energised due to snapping of LT conductor, due to which 8
Sheep’s & 12 Goats were electricuted in Urlakatte village, Jagalur
taluk, Davangere district on 24.6.2011.
2. One of the major
electrical accident occured on 10.9.2011 at 10.15.A.M in Arsikere taluk,
Hassan district. In which five people died and more than twenty persons
were injured.The Victims who were sitting on the top of lorry had
accidently came in contact with 11kv Overhead line which was passing
across the road and got electricuted.
By analyzing all the above facts, it can be noticed that by adopting some of the
basic safety measures, maximum occurrence of the electrical accidents can be
prevented and most accidents can be avoided if we
Use care and common sense don’t do our self-get a professional to
do the job
Don’t mix water and electricity
Use a safety switch
15. Safe Measures:
Here are the some of the simple safety tips that can be adopted in
our day to day life by which many of the electrical accidents can be
avoided.
15.1 Common electrical hazards
Switch off all heating appliances if the power fails. Fires have been
caused when power returns unexpectedly.
Switch off before pulling out a plug. Grasp the plug – not the cord.
Don’t spray household cleaners and insecticides on power points or
switches. They may cause cracking and an electrical hazard.
Combustible material must be kept clear of all heating appliances, such as
bedding, clothes, curtains, furniture, newspapers, etc.
Wear dry leather gloves when welding. Touching the electrode can be
dangerous because of the voltage present.
Tie the tapes of the electric blanket to prevent creasing.
Page 78 of 81
Teach children that power points and appliances are not toys. Children can
touch live pins of plugs. Plastic covers for power points reduce the chance
of children inserting objects.
Some overseas products may not operate satisfactorily or safely under
Australian conditions using 240V 50Hz supply. Such products could be
hazardous if used without modification. Have them checked before use.
15.2 Cords, cables and plugs
Fully unwind extension cords before use as they may overheat.
Damaged cords and older style plugs are dangerous. Have them replaced.
Never connect a piggyback plug or ordinary plug on the ‘wrong’ flex like
this - the live pins could kill you.
Don’t stack plugs. It can overload the power point and cause a fire.
Home-made extension cords, wrongly wired or without an earth wire are
dangerous. Buy ready-made cords, they’re cheaper and safer
15.3 Electricity outdoors
Wiring to a caravan must be kept in good condition.
Be careful where you dig or drive stakes. There may be buried cables,
especially in areas with underground supply.
Don’t leave appliances and cords out in the weather – put them away
after use
Never use a portable appliance or extension cord where it could be
splashed or fall into the pool. Temporary or makeshift wiring
arrangements to pool pumps and spas are hazardous.
15.4 Electricity in the kitchen, bathroom and laundry
Electric shocks received in wet areas are more likely to be fatal than in other
locations as they often involve bare feet, minimum clothing and water. Take
extra care near swimming pools.
Do not immerse appliances in water to wash them unless
instructions clearly allow it.
Don’t touch appliances or switches with wet hands.
Do not use a portable electric radiator in the bathroom. A
permanently installed heater is much safer.
Never leave an appliance near the bath or basin. Children have been
electrocuted by pulling hairdryers into baths even though the
hairdryer switch was off. Unplug the appliance after every use.
Page 79 of 81
Dry shoes should be worn when using electrical appliances in
laundries, on concrete floors or outdoors. Electric shocks are much
more likely to be fatal with bare feet.
15.5 Electrical installation safety
Doing electrical work yourself can be dangerous. People have
been killed doing electrical work unsafely. By law any electrical
installation work must be done by a licensed electrician. They must
test the work and give you a uniquely numbered Certificate of Compliance Electrical Work to show it has been tested and ensure
it complies with the regulations. Your electrician may be required
to provide a copy of the certificate to the electricity network
operator.
Earth wires are usually colored green/yellow or green although older
installations may contain bare earth wires. Unless an appliance is
‘double insulated’ (marked ), the earth wire performs a vital safety
function in the event of equipment failure. In cords and plugs the
earth wire must be correctly connected only to the earth terminal
marked E or .
The installation earth is usually connected to a metal stake and
water pipe. Check occasionally to see that it is not loose or damaged.
If water pipes are being altered or plastic pipes are being installed,
have your electrician check the earth system.
Wiring can fail from age, overload or damage. Care is needed
when working near wiring, eg. sawing, nailing, or drilling into
walls. Older types of wiring can become brittle and should
not be handled.
