A snake entered a feeder box from which power is supplied to an industrial area. The snake died of electric shock and at the same time, power supply to the industrial area also got cut off. Concerned officers of electricity board could not find the reason for power failure for more than 10 hours. After search, they found 1.5 m long dead snake in the feeder box. They claim that they did not see such a problem earlier. Production loss for 10 hours, environment pollution due to DG (diesel generator) sets operated during the period, revenue loss for the power supplier and the inconvenience caused to public will add to large amount, though the cost of preventing such incident i.e ensuring no openings, is minuscule. Many times, we see open fuse boxes, partly opened doors of power distribution boards, etc which can lead to entry of reptiles and causing such damages and this has become an accepted norm for such industries.
