SAFETY SLOGANS

THE FOLLOWING SLOGANS SHOULD BE DISPLAYED AT EVERY SUB-STATIONS AND GRID SUB-STATIONS AND ALSO SELECTED PLACES ALONG THE LINE:

• No job is so urgent or no service is so important that it prevents you taking time to do safely

• Accidents do not happen, they are caused

• Work safe today-Be back tomorrow

• Monkey business has no business in any business

• Learn first aid, you may save several lives

• Men who knows Electricity best –Respect it

• Bright people use right tools

• Safety is everybody’s job

wires are noticed• While drilling bore wells ensure that the casing

pipes do not touch live wires while they are being lifted up

• Do not touch low lying or snapped conductor• Do not lean against electric poles• Do not stand beneath overhead lines while

heavy winds are blowing

MAINTENANCE OF DISTRIBUTION SYSTEM AND REDUCTION OF

ACCIDENTS THEREOFItem Item details Action taken as on 30/3/09 Remarks with programme for

periodic rectification action

Inspection of HT/LT lines, cutting of tree branches touching the lines

This is a continuous process. Prunning of treebraches are taken up in a planned way toensure minimum load shedding.

Replacement of damaged stays Whenever such cases are noticed, it is beingreplaced.

Repairing of tilted poles if any On priority it is being done.Restringing of conductors where there is inadequate clearance as per I.E. rules

Restringing of conductors are being taken upto increase the clearance. There are also veryold lines with long span and due sagging theclearance becomes inadequate. In order toavoid this we are in process to replace suchconductors with new conductors and to setclearance we are putting intermitant poles.

Maintenance of S/S (both 11/0.4 KV and 33/11KV

Item Item details Action taken as on 30/3/09 Remarks with programme for periodic rectification action

Proper up keeping of maintenance of registers of 33/11Kv s/s

It is being done. However to maitainuniformity common formats are preparedand will be supplied as registers to all s/s byend of May-2009

A time schedule for periodical inspection of distribution lines and S/S

Every year the JE & SDO make their shedule for checking lines & s/s synchrinising with the shut down taken by Gridco/OPTCL as well as DISCOM, so that there will not be any additional shutdowns.
