Wogwira ntchito akulowa m'malo mwa ballast mu kuwala kwapadenga mu chipinda chopumira.Wogwira ntchitoyo amazimitsa chosinthira magetsi.Ogwira ntchito akugwira ntchito kuchokera pamakwerero a mapazi asanu ndi atatu ndikuyamba kusintha ballast.Wogwira ntchitoyo akamaliza kulumikiza magetsi, wogwira ntchito wachiwiri amalowa m'chipinda chamdima.Posadziŵa ntchito imene ikuchitika pa nyali ya padenga, wantchito wachiŵiriyo anatembenuza choyatsira nyali kuti ayatse.Wantchito woyamba anagwidwa ndi magetsi pang'ono, zomwe zinamupangitsa kugwa kuchokera pamakwerero.Pa nthawi ya kugwa, wogwira ntchitoyo anatambasula dzanja lake kukonzekera kutera, zomwe zinachititsa kuti dzanja liwonongeke.Kuvulalako kunafunikira opaleshoni, ndipo wogwira ntchitoyo anagonekedwa m’chipatala usiku wonse.
Ngakhale kuti zochitika zam'mbuyomu ndizongopeka, njira yotsekera ndi tagout imalongosola molondola kuvulaza komwe kungachitike ngati mphamvu yowopsayo siyikuyendetsedwa.Mphamvu yowopsa imatha kukhala mphamvu yamagetsi, mphamvu yamakina, mphamvu ya pneumatic, mphamvu yamankhwala, mphamvu yamafuta kapena mphamvu zina.Ngati sichikuyendetsedwa bwino kapena kumasulidwa, ikhoza kupangitsa kuti chipangizocho chizigwira ntchito mosayembekezereka.Mu chitsanzo ichi, wogwira ntchito yowunikira amayenera kuyika dera lophwanyira dera ndikuyambitsalock-out and tag-out (LOTO) ndondomeko.Mphamvu zamagetsi paziwombankhanga zodzipatula zimatha kupewa kuvulala pomwe chosinthira chowunikira chayatsidwa.Komabe, kungozimitsa mphamvu kwa wophwanya dera sikokwanira.
Ogwira ntchito zakunja akamagwira ntchito mogwirizana ndi muyezowu, olemba anzawo ntchito pamalowo ndi owalemba ntchito akunja azidziwitsana za njira zawo zotsekera kapena zotsekera.Ndikofunikiranso kukhazikitsa zida zomwe zimagwiritsa ntchito njira zabwino monga makiyi kapena maloko amtundu wa mawu achinsinsi kuti chipangizo chopatula mphamvu chizikhala chotetezeka ndikuletsa makina kapena zida kukhala zopatsa mphamvu.
Zofunikira za OSHA zokhudzana ndi miyezo yowongolera mphamvu yowopsa zitha kupezeka mu 29.CFR.1910.147.Mulingo uwu umafuna olemba anzawo ntchito kupanga mfundo za LOTO pakukonza ndi kukonza makina ndi zida, pomwe kuyatsa kapena kuyambitsa mwangozi makina kapena zida, kapena kutulutsa mphamvu zosungidwa kungawononge antchito.Olemba ntchito akuyenera kupanga mapulani ndikugwiritsa ntchito njira zotetezera zida zotsekera zoyenera kapena zida zolembera ma tag ku zida zopatula mphamvu, ndikuyimitsa makina kapena zida kuti apewe kuyatsa mwangozi, kuyambitsa, kapena kutulutsa mphamvu kuti apewe kuvulala kwa ogwira ntchito.
Chinthu chofunika kwambiri pa ndondomeko ya LOTO ndi ndondomeko yolembedwa.Kuphatikiza apo, muyezowo umafuna olemba anzawo ntchito kupanga njira zowongolera mphamvu, zomwe zikutanthauza kuti njira zotsekera ndikukonza zida ziyenera kulembedwa.Mwachitsanzo, ngati chipangizo chowongolera mpweya chiyenera kukonzedwa, njira yozimitsa magetsi iyenera kuphatikizapo dzina / malo a gulu loyendetsa dera ndi nambala yamagetsi mu gululo.Ngati dongosololi lili ndi mphamvu zambiri, ndiye kuti pulogalamu yolamulira iyenera kufotokozera njira yodzipatula magwero onse a mphamvu.Asanayambe kugwira ntchito pamakina kapena zida zokhoma kapena zolembedwa, ogwira ntchito ayenera kutsimikizira kuti zidazo zidazimitsidwa ndikuzimitsidwa.
Zina mwazinthu zazikulu za pulani ya LOTO zikuphatikiza kuphunzitsa antchito ndikuwunika pafupipafupi njira za LOTO.Maphunziro amafunikira pa ntchito yopatsidwa ntchito ndipo ayenera kuphatikizapo maphunziro ozindikira magwero owopsa a mphamvu, mtundu ndi kuchuluka kwa mphamvu zomwe zilipo kuntchito, ndi njira ndi njira zomwe zimafunikila kuti pakhale mphamvu zodzipatula ndi kuzilamulira.Pamene kukula kwa ntchito kumasintha, kuyika makina atsopano kapena kusintha kwa machitidwe kungabweretse zoopsa zatsopano, maphunziro owonjezera amafunika.
Kuwunika kwanthawi ndi nthawi ndi kafukufuku wapachaka wa njirazi kuti atsimikizire kulondola kwa njirazo kapena kudziwa zosintha kapena zowongolera zomwe ziyenera kuchitidwa.
