WHY SAFETY BEING A HUMAM , MORAL RESPONSIBILITY FOR ALL OF US TO HELP OTHERS, SOCITY AND ENVIORNMENT.
safety guidelines for our valued consumers • Guidelines for Domestic consumers • Guidelines for Commercial consumers • Guidelines for Industrial consumers • Dealing with a Downed Power Line • Sub-Stations and Transmission Lines
Domestic Consumer • Use standard pins to tap supply of power from the plug points. • Always use standard ISI marked materials even though they may cost a little more. • Replace a fused bulb only after switching it off. • Plug points of heavy appliances like - refrigerator, mixer, iron, wet grinder, washing machine, etc. must be properly earthed and the power should be drawn only through a 3-pin plug. • Keep a bulb in place in all the lamp holders in the house.
Commercial Consumer • Get all your wiring done only through a licensed contractor. • Do not allow tying up of advertisement boards, or flags and banners to the electric post. • Do not allow loading of a vehicle to a height that it runs the risk of coming in contact with overhead supply lines. This kind of accident could be fatal for all the passengers.
Industrial Consumer • Place 'Men at Work' sign on all the switches before commencing work. Ensure that fuses are withdrawn before any work for added safety. • Always treat a circuit as 'alive' unless until it is proved otherwise beyond doubt. • Ensure that all the splices and connections are fully secured and do remember to discharge any cable to earth before setting out to work on its core. • Keep rubber mats before the electrical switches and have the rubber gloves periodically checked.
Industrial Consumer • Make sure that workers are fully familiar with all kinds of fire fighting equipments that are available and they know which ones can be used in case of electrical fire. You can use sand or blankets to contain a fire caused due to electrical fault. • Do warn others when they happen to be dangerously close to high tension electrical apparatus. • Do turn away your face whenever a flash or an arc is expected. • Do not close any switch without knowing which and all circuits may be under its control and exactly why that switch has been kept open.
Industrial Consumer • Do not touch or tamper with any electrical gear or a conductor unless you have ascertained that it is dead and earthed. A high-voltage apparatus is known to give leakage shock or flash without you having actually touch it ! • Do not touch a circuit with your bare fingers or the hand or some other make-shift device to discover whether it is alive or dead. • Do not close or open a switch hesitatingly. Always do it firmly and quickly. • Do not allow usage of frail wires with worn out insulation.
Industrial Consumer • Don't throw water on live equipments in case of electric fire. It could prove out to be highly dangerous. Also, • Do not make use of fire extinguishers on electrical fires unless they are clearly marked for use under such a condition. • Do not go near running belts of machine components. • Do not bring a naked flame near any oil filled equipment and strictly prohibit any smoking in the area where batteries are installed. • Do not allow your visitors to venture into high voltage zones in your work place. • Do not enter excavation sites or the trenches that smell of obnoxious gas and don't work in poorly lit conditions.
Downed Power Line • No matter how well SEB is prepared, downed power lines can not be avoided. A tree can fall on taking several lines down with it, or a vehicle can spin out of control and crash into an electric post resulting in breakage of power lines ! No matter how a line gets broken, once you have spotted one do stay away from it ! • You should bring such an incidence to the knowledge of local office of BSEB so that they can take proper action immediately and prevent untoward accidents.
Sub-Stations and Transmission Lines • Be careful to avoid sub-stations ! The sub-station is the place where huge amounts of electrical power is reduced to a lower voltage making it fit for transmission down to households. The fence surrounding a sub-station always has a barbed wire on top and you will also see a sign like DANGER - HIGH VOLTAGE. The sign is there for your own safety. So stay clear of such an installation. Avoid places with similar warnings like electric poles, towers, and other structures
STATUATORY ACCIDENT AFFECTS NOT ONLY INDIVIDUAL BUT ALSO AFFECT SOCIETY AND NATION
REPORT OF ACCIDENT( 1 ) Indian Electricity Act 1956: (Rule-44 A) To Whom to be Reported: Electrical Inspector Officer In-charge of Local Police Time limit: Telephonic information Within 24 hr. Written report Within 48 hr.
REPORT OF ACCIDENT( 2 ) RULE 44-A OF IRE 1956: IF ANY ACCIDENT OCCURRED IN CONNECTION WITH GENERATION, TRANSMISSION, SUPPLY OR USE OF ENERGY IN OR IN CONNECTION WITH, ANY PART OF ELECTRIC SUPPLY LINES OR OTHER WORKS OF ANY PERSON AND THE ACCIDENT RESULTED IN OR IS LIKELY TO HAVE RESULTED HUMAN BEING OR ANIMAL LIFE SUCH PERSON OR ANY AUTHORIZED PERSON OF THE STATE ELECTRICITY BOARD OR SUPPLIER NOT BELOW THE RANK OF J E OR EQUIVALENT SEND TO THE INSPECTOR TELEGRAPHIC REPORT WITHIN 24 HOURS OF THE OCCURRENCE OF FATAL ACCIDENT AND WRITTEN REPORT IN THE FORM SET OUT IN ANNEXURE XIII WITHIN 48 HOURS OF THE KNOWLEDGE OF OCCURANCE OF FATAL AND ALL OTHER ACCIDENTS .
REPORT OF ACCIDENT( 3 ) PENALITY FOR BREACH OF RULE WHERE, IN CONTRAVENTION OF RULE 44-A ANY PERSON RESPONSIBLE FOR GENERATION, TRANSMISSION CONVERSION, DISTRIBUTION, SUPPLY OR USE OF ENERGY FAILS TO REPORT INSPECTOR AND AUTHORIZED CONCERED,THE OCCURRENCE OF ACCIDENT, SUCH PERSON SHALL BE PUNISHABLE WITH THE FINE WHICH MAY EXTENT TO THREE HUNDRED RUPEES.
Crossings over Telegraph or Telephone Lines and P.T.C.C : Communication circuits coming under the influence of electric field of high voltage power line experience extraneous induction, which may introduce noise in communication equipment and cause danger to the equipment and persons handling them. Therefore, it is very essential that whenever power liens and communication lines pass close to each other suitable measures are taken. Approval of PTCC (Power Tele communications Co-ordination Committee) may be obtained. Further, while crossing the telecom lines, the following points may be observed : • The power lines cross over the telecom lines because the Diameter of power line conductors is generally Conti…..
greater than telecom line conductors. • The angle of crossing shall be as far as possible 90°, but shall not be less than 60°. • A safe clearance between the communication lines and overhead power lines has to be maintained in accordance with the PTCC code of practice. • Power contact protectors are to be installed on all conductors of telecom lines at crossings with HV power lines. • The telecom lines shall be erected close to the support of the OH power lines for increased clearances.
MINIMUM CLEARANCE ( 3 ) UP TO 33 KV SYSTEM TELECOM LINE AND GUARD WIRE -:1.22 METER ( 4’ ) TELECOM LINE AND CONDUCTOR OUP TO 11 KV :1.525 METER ( 5’ ) TELECOM LINE AND CONDUCTOR OF 33 KV :1.1.830 METRE ( 6’ )
Road Crossings : The ground clearance of the guard wire and strength of the supports on either side of the road have to be considered in installing a cradle guard at the road crossings. The supports on either side of the road on which the cradle guard terminates are earthed separately and the line should not cross at an angle less than 60°.
