The document discusses electrical accidents in India, their causes, and measures to prevent them. It provides statistics showing that most accidents occur at the distribution level and are caused by accidental contact with live wires or equipment. Common issues contributing to accidents include lack of maintenance, unprotected equipment, and unauthorized construction near power lines. The text recommends safety measures like proper insulation, grounding, use of protective devices, maintaining clearance from lines, and increasing public education through sensitization workshops.

MORE POTENTIAL ENERGY YOU HAVE ACCUMULATED.
 DOMINOES LINE UP ENOUGH AND, WITH A SIMPLE FLICK,
IT CAN START A CHAIN REACTION OF SURPRISING POWER.

Electrical Accident Analysis – Issues & Challenges
• Most of the accidents occurs at distribution
level.
• Maximum number of accidents occurred due
to accidental contact with live electric wire or
equipment and snapping of conductor,
inadequate / lack of maintenance.

15. Electric safety, Why is it needed?
• On an average 16 persons died out of electrical accidents every
day in 2017-18 across the country.
• According to National Crime Records Bureau data on
Accidents for the year 2015, 13% cases of accidental fire
were due to Short circuit.
• According to National Crime Records Bureau data on
Accidents for the year 2015, 3% of total un-natural death is
due to Electrocution.
• Huge amount of money is being spent for compensation
and maintenance due to electrical accidents.

18.  Intimation of Accidents :- Any electrical accidents related
to utilities shall be reported to the concerned Electrical
Inspector within 48 hours.
 CEIG to inquire and report as to the cause of any accident
under its jurisdiction
 Every Electrical Inspector or other person holding an
inquiry have all the powers of a civil court under the Code
of Civil Procedure
 The prepared report may be given to the concerned
organizations for further actions and to the concerned law
enforcement agency.
Inquiry of Electrical Accidents

19. What are the Issues/challenges in our
country??
Electrical Accident Analysis – Issues & Challenges
• Inadequate and substandard quality use of Personal
Protective Equipments (PPEs)
• Electrocution in houses are frequent due to lack of proper
safety devices like Residual Current Device,
wiring/switches having poor IR
• Substandard quality of wire, no heed towards hazards and
taking it casually.
• Short Circuiting in building due to lack of maintenance
schedule
• Lack of proper earthing system

20. What are the issues/challenges in our
country??
Electrical Accident Analysis – Issues & Challenges
• Illegal construction of buildings in proximity to existing
lines
• Open DBs for service lines and lack of maintenance
• Ungaurded distribution transformers in crowded area.
• Unauthorised digging where underground cables are
buried
• Electrocution to animals and people due to non-
compliance of safe clearance and maintenance schedules
• Lack of maintenance of electric supply lines.

30. STEP & TOUCH POTENTIAL
| Presentation title and date

31.  Regular sensitization of utilities regarding electrical
safety are carried out through workshops and
seminars.
 During the last two years, 12 numbers of sensitization
workshops were carried in collaboration with Public
and Private organizations.
 Regional workshops on Electrical Safety are being
planned in collaboration with Public & Private entities
throughout the country for year 2019-20.

Sensitization

32. Sensitization
 Formation of a Sub-Committee from among the
nominated expert member from State
Electrical Inspectorates for delivering
lectures and spreading this message of
electrical safety through the awareness
program in the state.
 Sensitization at district level, Panchayat level,
community level.
 Thrust on lower strata sensitization .
Electrical Accident Analysis – Issues & Challenges

33. Sensitization
Electrical Accident Analysis – Issues & Challenges
 SEE -> OBSERVE
 REACT -> RESPOND
 CONSCIOUS -> SUB CONSCIOUS
 CHANGE -> TRANSFORMATION

34. Few Examples of Sensitization
in your organisation
• Safety awareness campaign once in a month in
my Organisation.
• Contribution to the society, maybe nearby
colony/school/college/village & making them
aware of safety aspects – Corporate Social
Responsibility(CSR)
• Informing to Local Electrical Inspectorate about
your sensitization actions that in-turn inspires the
local authority.

35. Need to be more SACHET (सचेत)
Stick to Safety Standards
Adequate use of PPEs
Co-ordination at workplace
Hazards identification
Emergency action plan
Training to employees
