Xa ilori yebhakethi yasemoyeni, ibhedi yelori ephakanyisiweyo, impompa yekonkrithi, intambo yekhranethi, i-auger yezolimo, okanye unxibelelwano lwemasti yephenyane okanye i-arcs ingena kumphezulu wosasazo wombane ongaphezulu okanye wothumelo (oludla ngokuba namandla ku 4,000 volts ukuya kwi-500,000 volts), inqwelo-mafutha eqhotyoshelweyo ibe ziinqwelo ezirhuqwayo ezizincamatheleyo, kunye neenqwelo ezincanyathiselweyo zentsimbi. yevolts ngelixa impazamo yangoku ihamba ngee-asi kunye namatayara ukuya emhlabeni. Ngaphakathi kwi-cab okanye i-fiberglass e-insulated ibhakethi, umqhubi uhlala engonzakali ngokupheleleyo ekuqaleni (esebenza njengentaka ehleli ecingweni kwi-voltage enye enokubakho), ngelixa ** ephuma kwi-cab ngonyawo olunye kwisitepsi selori kunye nonyawo olunye emhlabeni ibhulorho ebulalayo ye-10,000-volt enokubakho umahluko kuyo yonke intliziyo ("Touch Potential in the energination in the)*** Iimitha ezili-15 (iinyawo ezingama-33 ukuya kwezingama-50) zesithuthi ziqhuba amawaka ee-volts ukuya phezulu kumlenze omnye kwaye ezantsi komnye ("Inyathelo elinokwenzeka")**. Nangona kunjalo, ukuba impazamo eqhubekayo itshisa amatayara erabha enentsimbi ukuba ivuthe kwaye ibangele ** ukuqhuma kwevili le-pyrolysis okanye umlilo we-cab **, umqhubi ongaphakathi kufuneka enze i-*Two-Foot Jump-Clear kunye ne-Bunny-Hop / Shuffle Escape ** ukuze uphile. Ukuba isithuthi somsebenzi okanye inqanawa ichukumisa intambo yombane, tsalela umnxeba kwinombolo yakho yexesha likaxakeka ngoko nangoko (911 eUnited States naseKhanada, 112 kulo lonke elaseEuropean Union, 999 eUnited Kingdom) okanye ujonge uluhlu lwethu lwehlabathi. amanani kaxakeka. Malunga neemeko ezingxamisekileyo zombane ophezulu, funda izikhokelo zethu iintambo zombane ezehliweyo kunye nombane wesithuthi, I-arc flash blast, i-high-voltage switchgear, kunye nokutsha kwe-substation, i-crane tip-over, ukuwisa umthwalo omisiweyo, kunye noqhagamshelwano lwentambo yombane ngaphezulu, kwaye uncedo lokuqala lombane.

Yenza oku ngoku¶

1. Ukuba ungaphakathi kwekhebhu okanye i-fiberglass ibhakethi yesithuthi echukumisa intambo yamandla engaphezulu kwaye AKUKHO mlilo, HLALA NGAPHAKATHI, gcina izandla zakho kunye nomzimba wakho kude nezinto eziphantsi komhlaba, kwaye ufowunele kwa-911 / 112 / 999 kunye nezinto eziluncedo zombane. Ngaphakathi kwekhebhu yesithuthi, ukwisakhono esifanayo sombane njengekheji yentsimbi ejikelezileyo. UNGAphumi kwikhabhi ukuze ujonge umonakalo, kwaye ukhale kubo bonke abantu osebenza nabo kunye nababukele phantsi ukuze bahlale okungenani iimitha eziyi-15 (iinyawo ezingama-50) kude kwaye ungaze uchukumise umzimba welori, izinto ezikhuphayo, izibambo zocango, okanye izixhobo ezingqiyame kwi-chassis.
2. Ukuba ungaqhawula ngokukhuselekileyo unxibelelwano olungaphakathi kwekhebhu okanye i-emele ngokuthoba ibhedi yokulahla inkunkuma okanye ukurhoxisa i-boom, KUPHELA ukuba ucingo alusongwanga okanye alunyibilikiswanga okanye lunyibilike kwibhoom, shenxisela ibhoom kwicala elichasene ngqo loqhagamshelwano. Isilumkiso: Ukuba icondakta engaphezulu iqhagamshelwe phantsi kwesibiyeli okanye idityaniswe kwibhoom, izama ukutsalela kude intambo**-volping umqhubi kwiteksi okanye abasebenzi abasemhlabeni. Ukuba ucingo lutshixiwe, misa ulawulo kwaye ulinde inkampani eluncedo ukuba ikhuphe amandla kwaye iwubeke phantsi umgca.
3. Ukuba amatayara esithuthi aqalisa ukutshaya, ukubamba umlilo, okanye ukudubula, okanye ukuba ikhabhu igcwele umlilo, KUFUNEKA usilahle isithuthi usebenzisa iTwo-Foot-Foot Jump-Clear Technique. Vula ucango lwecab ngokubanzi, yima kungqameko lwekhebhu okanye kwibhodi yokubaleka, unqumle iingalo zakho ngokuqinileyo phezu kwesifuba sakho, kwaye ushiye ukuze utsibe inqwelo-mafutha phambi kokuba uthinte unyawo okanye unyawo. INYAWO zombini ziwela emhlabeni ngephanyazo kanye**. Ungaze ukhwele ezantsi kwileli okanye ubambe isiphatho sokubamba ngelixa uchukumisa umhlaba, akufuneki ubambe ilori kunye nomhlaba ngaxeshanye.
4. Zakuba iinyawo zakho zibethe emhlabeni, UNGAZE uhambe okanye ubaleke ngomkhondo wesiqhelo, ibunny-hop iinyawo zombini zicinezelwe ngokuqinileyo OKANYE utshixize iinyawo zakho isithende ukuya enzwaneni ungakhange uphakamise nelinye de ube ubuncinane ubukumgama weemitha eziyi-15 (iimitha ezingama-30 [iimitha ezili-100] kumhlaba omanzi okanye iingcingo zothumelo). Umbane uqukuqela uphuma ngaphandle kwelori usiya ngaphandle. iiripples echibini, kunye neripple ripple nganye yehla ngamawaka e-volts ngemitha. Ukuthatha i-75-centimeter eqhelekileyo (i-intshi ezingama-30) ukuhamba ibeka unyawo lwakho lwangaphambili kwiringi ye-3,000-volt kunye nonyawo lwakho lwangasemva kwiringi ye-7,000-volt, ukuthumela i-4,000-volt ebulalayo ngoku unyuka umlenze omnye, ngokusebenzisa i-pelvis yakho kunye ne-torso, kwaye uhle ngomnye umlenze.
5. Ukuba ubukele okanye ungumsebenzi ophantsi kwindawo yomsebenzi xa ilori yebhakethi, impompo yekonkile, okanye ilori yokulahla inkunkuma ibetha ucingo, UNGAZE ubalekele kwilori ukuya kuhlangula umsebenzi ongekho zingqondweni okanye utsale ivalve yomgangatho ophantsi. Rhoqo ngonyaka, abasebenzi abaninzi abaphantsi komhlaba bafa ngenxa yokutsalwa ngumbane ngenxa yokuba bebona umntu osebenza nabo othukile ecaleni kwelori, aze awele ngaphakathi erhuqa ixhoba aze awele ngaphakathi aze afe. Hlala umgama oziimitha ezili-15 (iinyawo ezingama-50) umva, shixiza okanye bunny-hop ngaphandle ukuba uva nakuphi na ukuntyiloza kumathole okanye iibhutsi zakho, kwaye ulinde into eluncedo yombane ukuqinisekisa ukuba umgca awukho mandla kwaye usekelwe ngokubonakalayo.
6. Ukuba imasti yephenyane okanye isikhephe esirhuqa isikhephe esirhuqwayo sinxibelelana nentambo yombane engaphezulu kwirempu yesikhitshane okanye ibhulorho, SUKUMtsibela ukusuka kwialuminiyam okanye umgangatho wefiberglass emanzi ukuya emanzini ajikeleze inqanawa. Amanzi ajikeleze isiseko esisemhlabeni okanye esijikelezayo athwala ukuthambeka kwamandla ombane okubulalayo (**Emanzini Ukothuka koMbane) UkuntywilaIVoti yoMbane eNgamanzi ngoko nangoko. Hlala womile embindini we-cockpit kude ne-aluminiyam yokuhlala, i-shrouds, kunye neefestile ukuba zisemanzini, okanye uphumeze umhlaba owomileyo Ukutsiba kweenyawo ezimbini kunye nokuShuffle ukuba ukwindawo yokupaka isikhephe.

Ifiziksi yombane yeTouch Potential, iNyathelo elinokwenzeka, kunye neRings Gradient eGround¶

Ukuze uqonde ukuba kutheni ukuhamba ngokuqhelekileyo kufutshane nelori enamandla kukubulala, nokuba iibhutsi zakho zingaze zichukumise ilori okanye ucingo, kufuneka uqonde ukuba i-high-voltage fault isebenza njani xa ingena emhlabeni okanye i-asphalt.

1. IKhowuni yeVoltage ("IiRipples echibini")¶

Ngokungafaniyo nocingo lobhedu, olunokumelana nombane kufutshane ne-zero (\(0.0000017\text{}\Omega\cdot\text{m}\)), umhlaba, igrabile, ikhonkrithi, kunye ne-asphalt zinezinga eliphezulu lokumelana nombane (\(50\text{ ukuya }3,000\text{}\Omega\cdot\text{m}\)). Xa ibhedi yokulahla ephakanyisiweyo okanye i-crane boom iqhagamshela 13,800-volt (\(13.8\text{kV}\)) umgca wosasazo wesigaba esithathu (8,000 volts isigaba ukuya emhlabeni), impazamo yangoku iqukuqela phantsi isakhelo selori yentsimbi, ngeerimu zamavili, ijikeleza ngapha kwekhabhon-emnyama yerabha yamatayara ukuya kumavili erabha amnyama ukuya kwidigri yentsimbi. - Ngenxa yokuba umhlaba uyaxhathisa oku kuhamba kwangoku, amandla ombane awehli aye kwi-\(0\text{volts}\) kwindawo apho umkhuseli ophumayo achukumise ukungcola. Endaweni yoko, i- **hemispherical voltage cone ** ifom emhlabeni ojikeleze ilori: - Kanye kwindawo yokuphuma okanye indawo yokudibanisa itayara, umhlaba ngokwawo uku 8,000 volts. - Ku- 1 imitha (ienyawo ezi-3.3) kude nelori, ukuxhathisa komhlaba kwehlisa amandla ombane omhlaba ukuya malunga ne- 4,500 volt **. - Kwi-*2 yeemitha (iiawo ezi-6.5)** kude, amandla ombanomhlaba ngu*2,800 vols**. - Kwi-*3 yeemitha (iinwo ezili-10) kude, amana ombane omhlaba ngu 1,800 volts**. - Umbane uyaqhubeka ukuhla kwizangqa ezigxininisiwe ukuya ku 10 ukuya kwiimitha ezingama-30 (iinyawo ezingama-33 ukuya kwezi-100) ide ifikelele kwinyani eyi-\(0\text{-volt}\) ekude emhlabeni.

2. Kutheni iNyathelo elinokubakho kunye neTouch Potential zibulala ngoko nangoko¶

Umzimba womntu unokumelana nombane wangaphakathi (ukusuka kwisandla ukuya ezinyaweni okanye ukusuka ezinyaweni ukuya ezinyaweni ngaphaya kwesikhumba esimanzi) kuphela ** 500 ukuya kwi-1,000 ohms , kwaye nje kancinci ** 0.1 amperes (100 milliamperes) ** yokudlula ngoku ngokudlula esifubeni kubangela ukufa ** i-fibrillation ye-ventricular . 1. I-Touch Potential (Ukuvala iLori kunye noMhlaba): Ukuba umqhubi uvula ucango lwekhebhu, ubambe intsimbi yokubamba intsimbi ngesandla sasekhohlo (ku 8,000 volts), aze abeke ibhutsi yakhe yasekunene emhlabeni umgama oyimitha e-1 (ku 4,500 volts), ibhulorho yomzimba wabo i-3,500 volts-. Ngomthetho ka-Ohm (\(I = V / R\)), \(3,500\text{volts} \div 1,000\text{ohms} = \mathbf{3.5\text{amperes}}}\), ixesha eli-35 lomgubasi obulalayo, udlula ngokuthe ngqo esandleni sabo ukuya entliziyweni ukuya ezinyaweni zabo. 2. Inyathelo Elinokubakho (Ukudibanisa Izangqa Ezimbini Zobumdaka Ngemilenze Yakho): Masithi utsibela ngaphandle kwelori ungakhange uyichukumise, uhlale kwimitha e-1 ukusuka kwitayara, uze uthathe umtsi oqhelekileyo ** oyimitha eyi-0.9 (iinyawo ezi-3) ukubaleka ukuya kwindawo ekhuselekileyo. Unyawo lwakho lwangasemva lumi kwi-4,500-volt indandatho yobumdaka kwaye unyawo lwakho lwangaphambili lumi kwi-2,800-volt indandatho yobumdaka. Ngenxa yokuba izicubu zakho ezithambileyo ziqhuba umbane ngcono kakhulu kunokungcola okomileyo, imilenze yakho emibini yenza ibhulorho yokunqanda ukunyathela ephantsi kwi- **1,700-volt yenyathelo elinokwenzeka **. Okwangoku ihlumela umlenze omnye, kwiimbilini zakho ze-pelvic kunye nesisu esisezantsi (ngoko nangoko i-tetanizing kunye nokukhubazeka kwemisipha yomlenze wakho), okubangela ukuba uwele ** ubuso bokuqala kunye nobude obugcweleyo kwiimitha ezi-2 (iinyawo ezi-6.5) zokungcola *, ngokukhawuleza ubeka izandla zakho kunye nesifuba ngaphesheya kwe- ** 3,000-volt span **, ukumisa intliziyo yakho.

Ukuthelekiswa kwemoto yomsebenzi kunye nezixhobo zoqhagamshelwano lwamandla ombane¶

Ingozi yokuqhushumba kweTire Pyrolysis: kutheni amavili elori anamandla aqhuma ngexesha, kunye neeyure emva koko, ukudibana¶

Xa ilori yokulahla inkunkuma, ilori yebhakethi, okanye i-crane idibana nomgca we-voltage ephezulu, amavili erabha awayikhuseli ilori ukusuka emhlabeni. Amatayara eelori ezirhwebayo adityaniswe ne 30 yepesenti eqhuba ikhabhoni emnyama kwaye yomelezwe nge amabhanti entsimbi alukiweyo aphezulu kunye neengcingo zentsimbi.

1. Kutheni amatayara evutha umlilo kwaye aqhume¶

Njengoko amakhulu-khulu e-amperes ye-fault current edlula kwi-rim yevili lentsimbi kwiibhanti zamavili entsimbi ukufikelela kwi-pavement, ukufudumeza okunamandla okuxhathisa ($ I-squared-R $) kufudumeza amabhanti entsimbi ngaphakathi kwesidumbu serabha ngaphezulu kwe 400 degrees Celsius (750 degrees Fahrenheit) ngemizuzwana. - I-Pyrolysis yangaphakathi (iDistillation eyonakalisayo yeRubha): Ngaphakathi komngxuma wetayara elivaliweyo elivaliweyo, elixinzelelweyo (livuthelwe ukuya ku 700 ukuya kwi-830 kilopascals [100 ukuya kwi-120 psi]), amabhanti entsimbi atshisayo awenza abe ngumphunga irabha yangaphakathi yelayini ibe yigabhoni exineneyo, ihydrocarbon, ihydrocarbon, i-hydrocarbon, butadiene, kunye ne-carbon monoxide ). - I-Auto-ignition kunye ne-Supersonic Rapture: Xa loo gesi yepyrolysis eshushu kakhulu ixubana nomoya ocinezelweyo ngaphakathi kwitayara kwaye ifikelela kwiqondo lobushushu obuzitshisayo, ukudubula kwangaphakathi kwekhemikhali kwenzeka ngaphakathi kwingxowa yetayara. Uxinzelelo ludlule7,000 kilopascals (1,000 psi), luvuthela itayara lelori enzima kunye nentsimbi yentsimbi ngokwahlukileyo ngokothusayo okukhupha amaqhekeza angama-20 eekhilogram (45-eponti) ukunyathela umgama oziimitha ezingama-100 (330 iinyawo) emoyeni kwaye kusete itanki yesali yedizili yedizili. - I-24-Hour Pyrolysis Hazard ilibazisekile: Nasemva kokuba inkampani eluncedo ivale intambo yombane kwaye icime amadangatye abonakalayo, ukubola kwepyrolysis eqhumayo kunokuqhubeka ngokungabonakali ngaphakathi kwivili lelori yorhwebo engaguqukiyo ukuya * ukuya kwiiyure ezingama-24 **, iqhuma ngaphandle kwesilumkiso ngelixa umqhubi erhuqailori. Amasebe omlilo aseka i-*100-imitha (330-unwo) indawo yokungabandakanywa malunga namatayara abonakaliswe kuqhagamshelwano lombane ophezulu de iikhamera zokujonga i-thermal ziqinisekise ukuba iirimu zipholile kubushushu be-ambient.

Ukwenziwa kwenyathelo ngenyathelo lokutsiba ngeenyawo-Ezimbini-Ecacileyo kwaye Shuffle / Bunny-Hop¶

Ukuba umsi, amadangatye, okanye amatayara aqhumayo akunyanzela ukuba ulahle ikhabhinethi yemoto enamandla phambi kokuba inkampani eluncedo ivale amandla, ukusinda kwakho kuxhomekeke kuhlobo olungqongqo lomzimba:

Inqanaba loku-1: ULungiselelo kunye nokuQaliswa kwiCab Door¶

1. Tyhiliza ucango lwecab yonke indlela luvuleke ukuze ibambelele okanye iphumle ngasemva kwiihenjisi kwaye ingakwazi ukujinga umva ukubrasha igxalaba lakho njengoko utsiba.
2. Hlola umhlaba ngokuthe ngqo ngaphantsi komnyango: Khangela iingcingo eziwileyo ezilele emhlabeni; ukuba ucingo lulele phantsi kocango lomqhubi, khwela ngapha kwekhonsoli kwaye utsibe kucango lomkhweli endaweni yoko.
3. Yima kumda womgangatho weteksi okanye kwelona nqanaba liphezulu lomileyo neenyawo zombini kunye: Musa ukuhla ngezinyuko ezisezantsi ngesandla esinye nonyawo olunye ngexesha.
4. Beka iingqiniba zakho kwaye unqumle iingalo zakho ngokuqinileyo esifubeni sakho: Xa abantu betsiba besuka kwinyathelo lelori eli-1-mitha-ubude (3.3-foot-high), uluvo lwabo lwendalo xa befika kukufikelela kwesinye isandla ngasemva ukuze babambe ibhalansi yabo kwi-fender yelori okanye kwifreyimu yocango. Ukuwela iingalo zakho phezu kwesifuba sakho kuthintela isandla sakho ekuchukumiseni umzimba welori onamandla emva kokuba iibhutsi zakho zibethe ukungcola (okunokuthi kubangele i-Touch-Potential electrocution).
5. Intlakohlaza iphumele ngaphandle kwaye ihlale kwiiNYAWO ZZIMBINI ngaxeshanye: Goba amadolo akho kancinci ukuze ufunxe impembelelo ngelixa ugcina izithende kunye namaqatha akho axinaniswe ngokuqinileyo kunye ukuze zombini iinyawo zibe kwiringi yombane efanayo. (Ukuba uwela ngasemva xa ufika emhlabeni, ungaze ubuyele emva kwilori; faka isilevu sakho kwaye ujikeleze emacaleni ngeengalo zakho kunye nemilenze yakho ibambene ngokuqinileyo, nangona ukuhlala uthe nkqo ngeenyawo ezimbini kukhuselekile kakhulu).

Imibuzo ebuzwa qho¶

Kutheni intambo yombane ene-voltage ephezulu ingenawo ukugqunyelelwa kwerabha ejikeleze ucingo njengentambo yolwandiso?¶

Ngaphezulu kwama-95 epesenti yokusasazwa kweentambo zombane ezixhonywe kwiipali zoncedo, azikho nto kwaphela, ialuminiyam okanye ucingo lobhedu. Ukujikeleza i-13,800-volt okanye i-115,000-volt yocingo olungaphezulu olunerabha eshinyeneyo okanye ukugquma kweplastiki ngokwaneleyo ukumisa i-arc ye-voltage kuya kwenza intambo ibe nzima kwaye ibe banzi kangangokuba izibonda zoncedo lwamaplanga kunye neengalo ezinqamlezayo ziya kuwela phantsi kobunzima kunye nomoya / umthwalo womkhenkce, ngelixa ubamba ukushisa kwangaphakathi. Endaweni yoko, iintambo zamandla ezingaphezulu zixhomekeke kumoya ovulekileyo njengesigqubuthelo. Qaphela ukuba iingcingo ezinombala omnyama wemozulu ("icingo lomthi" okanye amathontsi eenkonzo ze-multiplex) zinebhatyi yemozulu ecekethekileyo kuphela yokunciphisa iimpazamo zesebe lomthi, hayi ukugquma kokhuseleko lokwenyani, kwaye ziya kuphinda zifake umbane kuye nabani na obom okanye ileli eyichukumisayo.

Kutheni amavili erabha kwilori yebhakethi okanye imoto engenakwaneleyo ukugquma isithuthi emhlabeni?¶

Ngelixa irabha ye-latex ecocekileyo yelabhoratri isisigqubuthelo sombane, amavili elori yemoto kunye nezorhwebo enziwa ngokuxuba irabha kunye neepesenti ezingama-25 ukuya kuma-35 **ikhabhoni emnyama** (esebenza ngombane) kunye nokuqinisa i-casing nge **amabhanti ocingo olulukiweyo oluphezulu lwekhabhoni kunye namaso entsimbi yentsimbi**. Okubaluleke ngakumbi, kumandla ombane osasazo angama-4,000 ukuya kuma-34,500 volts, amandla ombane anokujikeleza ngokulula ngaphaya kwe-15-centimeter (6-intshi) yecala elisecaleni letayara okanye udlule ngqo kwikhompawundi yerabha emnyama esebenza ngekhabhoni kunye namabhanti entsimbi emhlabeni, ajike itayara libe yinto yokufudumeza eqhumayo kwaye igqabhuke.

Ngaba intambo yamandla engaphezulu kufuneka ichukumise ileli yam yealuminiyam okanye i-boom lift ukuze undibethe?¶

Hayi. Umbane one-voltage ephezulu unokutsiba (i-arc) unqumla isithuba somoya esivulekileyo uye kwisiseko sentsimbi esisezantsi, intambo yocingo, ileli yealuminiyam, okanye isebe lomthi elimanzi ngaphandle kokudibana. Ngelixa umoya owomileyo unamandla okuqhekeka kwe-dielectric amalunga ne-3,000 volts ngemilimitha nganye phakathi kweengqukuva zelabhoratri ezicocekileyo, ezijikeleze imiphetho yentsimbi ebukhali, umoya ofumileyo, uthuli, okanye iindlela ze-corona ezi-ionized kwiintambo zothumelo, ii-arcs ezinevoltage ephezulu zinokutsiba iisentimitha ezininzi ukuya ngaphezulu kwemitha, kwaye ukuvuthuza kwemimoya kubangela zombini i-3 yeemitha ukuya kwi-3 yeemitha ukuya kwintambo yomoya. 6.5 iinyawo) ngokungalindelekanga. Yiyo loo nto i-OSHA ifuna i-3-meter engqongqo (i-10-foot) ubuncinane bokukhutshwa kwesithinteli nakwimigca yepali eqhelekileyo.

Kufuneka ndenze ntoni ukuba ndingaphakathi kwecanopy yomthi okanye kwi-emele engafakwanga i-insulated kwaye ndiziva ndintyiloza ezinyaweni okanye ezandleni?¶

Ukuntyiloza okanye ukuntyiloza kwiibhutsi zakho, amathole, okanye kwiincam zeminwe ("ikhenkceza yombane") kuthetha ukuba umi ngapha kwethambeka lombane elibangelwa kukuvuza kwesiqu somthi, ibhom, okanye intambo emanzi ekufutshane neconductor yombane ophezulu. Yeka ngoko nangoko ukuya ngaselucingo okanye kwilungu lomthi; ukuba usemthini, qhawula unxibelelwano nesebe elimanzi elingaphandle lisiya ngakwicingo ngelixa uhlala kwindawo enye ye-equipotential trunk okanye wehla ngentambo eyomileyo ye-dielectric kude nocingo lwesigaba; ukuba uphantsi, lahla naziphi na izixhobo okanye iintambo ngoko nangoko, cinezela iinyawo zakho ngokuqinileyo kunye, kwaye ushixile isithende ukuya kuzwane kangangeemitha eziyi-15 (iinyawo ezingama-50) kude.

Kunini na xa kukhuselekile ukwenza iCPR kumsebenzi owothuswa yilori ebambe umbane?¶

Ungasondela kuphela kwaye uchukumise ixhoba xa enye yeemeko ezimbini i-100 yeepesenti idibene: nokuba (1) inkampani yombane iqinisekisile ukuba umgca we-overhead u-de-energized kwaye usekelwe, OKANYE (2) ixhoba lilele ngokupheleleyo ngaphandle kwendawo ye-15-metres (50-foot) yokunyathela kwaye ayichukumisi ilori, ucingo oluphantsi, okanye ukuqhubela ilori. Emva kokuba indawo ikhuselekile ngombane, umzimba womntu owothukileyo awugcini ** awugcinanga umbane, ukhuselekile ngokupheleleyo ukuba uthinte ulusu lwabo kwaye uqale ukunyanzeliswa kwesifuba ngokukhawuleza, ukuphefumla, kunye ne-Automated External Defibrillator (AED) izothuso. Ngenxa yokuba i-high-voltage alternating current ibangela i-fibrillation ye-ventricular okanye ukukhubazeka kokuphefumula ngelixa i-heart muscle ngokwayo isenempilo, i-CPR ekhawulezayo kunye ne-AED defibrillation inezinga eliphezulu kakhulu lokusinda. Ukuthatha izandla kwi-CPR, i-AED, kunye nekhosi yoncedo lokuqala kwi-Red Cross, i-St John Ambulance, okanye umboneleli wendawo ulungiselela abasebenzi bomsebenzi ukuze basindise ubomi emva kweengozi zombane.
