Electrical Accidents


ELECTRICAL SAFETY 

Safety is one of the most important aspects for every human being, especially while working on electrical installations.

          The  golden  rule  is  that  an  electrical apparatus must be regarded as being alive all the  times  except  when  the  equipment   has been specially made dead.

There are two aspects of safety –
1. Safety towards Users
2. Safety towards Service Providers

ELECTRICAL ACCIDENT

       An Electrical Accident is one which is caused directly or indirectly due to electrical causes that is, it includes electric shock or electric burns whether minor, major or fatal, whether suffered by railway servant or others.

          Every case where a person receives an electric shock or suffers injuries in connection with the generation, transmission, supply or use of electrical energy, should be treated as an Electrical Accident.

          Again, if a person gets injured, due to a fall from an electric post, it is better to treat it as an electric accident and report, as the fall may quite possible have been caused by an electric shock.  

ELECTRICAL ACCIDENT - STEPS TO BE TAKEN BY THE
 CONSUMERS

•         Cut-off the supply immediately from main switch board

•         Remove the body from contact from live conductor

•         Extinguish spark, if any

•         Give artificial respiration to the affected person or call for a doctor

•         Inform to the nearest

   

ELECTRICAL ACCIDENT - STEPS TO BE TAKEN BY THE ELECTRICAL OFFICIAL

          Cordon off the area so that no one else get injured

•         Arrange to cut-off the supply

•         Free the injured person from supply

•         Render First Aid to injured person and send for medical assistance

•         Carry out preliminary investigation to ascertain cause of accident  

•         Advise Police Authorities in case of fatal accident

•         Inform Factory Inspector in case of accident in workshop

 

MAIN POINTS TO BE COVERED IN AN ELECTRICAL ACCIDENT REPORT

•         A clear description of the locality with a neat sketch

•         Evidence including statement of eye-witnesses, staff concerned etc.

•         Analysis of evidence recorded

•         Findings as to the exact cause of accident

•         Fixing up of responsibility for the accident

•         Recommendations for preventing such accidents in future.  

FIRE IN ELECTRICAL EQUIPMENT
 

Fires that occur in electrical equipment or in equipment close to electric circuits preclude the use of water spray or foam type extinguishers. Such fires are extinguished by sand, carbon tetrachloride or carbon dioxide or halon type fire extinguishers.  

          Where the energized electrical equipment is involved in electrical fire, the non-conductivity extinguisher such as dry powder, carbon dioxide (without metal hom) or halon should be used. 

 

PRECAUTIONS AGAINST ELECTRICAL FIRE

•         Ensure elimination of arcs due to poor contacts

•         Avoid overloading of circuits

•         Over current & under voltage protection in Motors

•         Electric lamps shall not be surrounded by combustible material

•         Vicinity of cables should be kept clear of oily dirt

•         Avoid loose connections

•         Battery rooms should not have any sparking devices

•         Metal parts of the equipments shall be adequately bonded and earthed

•         Flammable gases and materials shall not be stored near electrical equipment
