- Between 1,00,000 to 5,00,000 ohms when dry

                    - 5000 ohms or less when wet

                    - Resistance decreases with the area of contact and contact pressure

•         In wet condition the body and contact resistance is low, therefore a small leakage becomes dangerous

•         Even 50 volts is sufficient to prove fatal if applied for an appreciable time

•         AC voltage have more severe effect than DC voltage

•         High current do not cause heart failures but extensive burns due to resulting flashover, may ultimately cause death, even if one survive the shock

•         Therefore, NEVER TAKE LIBERTIES WITH ELECTRICITY

EFFECT OF CURRENT ON HUMAN BODY

Magnitude of Current	Effect
1 to 8 mA	Perceptible, but not painful
8 to 15 mA	Painful shock, but muscular control is not lost
15 to 20 mA	Painful shock, Muscular control affected, can’t let go
20 to 50 mA	Severe Muscle contractions, Breathing difficult
50 to 100 mA	Serious contraction of heart muscle, Possible death, No known remedy
200 mA and above	Severe burns, Stoppage of heart, Death certain

 

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 power station/electrical officials
