Wantchito akuyika ballast mu nyali ya padenga m'chipinda chopumulirako. Wantchitoyo azimitsa switch ya magetsi. Antchito akugwira ntchito kuchokera pa makwerero a mamita asanu ndi atatu ndikuyamba kusintha ballast. Wantchitoyo akamaliza kulumikiza magetsi, wachiwiri amalowa m'chipinda chochezera chamdima. Posadziwa ntchito yomwe ikugwiridwa pa nyali ya padenga, wachiwiriyo adasintha switch ya magetsi kuti ayatse nyali. Wantchito woyamba adagwidwa ndi magetsi pang'ono, zomwe zidamupangitsa kugwa kuchokera pa makwerero. Pa nthawi yogwa, wantchitoyo adatambasula dzanja lake kukonzekera kutera, zomwe zidapangitsa kuti dzanja lake lisweke. Kuvulalako kudafunikira opaleshoni, ndipo wantchitoyo adagonekedwa m'chipatala usiku wonse.
Ngakhale kuti nkhani yapitayi ndi yongoganizira chabe, njira yotsekera ndi kuyika magetsi imafotokoza molondola za kuvulaza komwe kungachitike pamene mphamvu yoopsayo siikulamulidwa. Mphamvu yoopsa ikhoza kukhala mphamvu yamagetsi, mphamvu yamakina, mphamvu ya pneumatic, mphamvu ya mankhwala, mphamvu ya kutentha kapena mphamvu ina. Ngati siikulamulidwa bwino kapena kutulutsidwa, ingayambitse kuti zipangizo zigwire ntchito mosayembekezereka. Mu chitsanzo ichi, wantchito wokonza magetsi ayenera kuti anapatula dera lomwe lili pa chosokoneza magetsi ndikuyambitsandondomeko ya lock-out ndi tag-out (LOTO)Mphamvu yamagetsi pa chopatulira magetsi chodzipatula imatha kuteteza kuvulala pamene chosinthira magetsi chikugwira ntchito. Komabe, kungozimitsa magetsi pa chopatulira magetsi sikokwanira.
Pamene ogwira ntchito zakunja akuchita zinthu zomwe zikugwirizana ndi muyezowu, olemba ntchito omwe ali pamalopo ndi olemba ntchito akunja ayenera kudziwitsana za njira zawo zotsekera kapena kutseka. Ndikofunikiranso kukhazikitsa zida zomwe zimagwiritsa ntchito njira zabwino monga makiyi kapena maloko amtundu wa mawu achinsinsi kuti chipangizo cholekanitsa mphamvu chikhale pamalo otetezeka ndikuletsa makina kapena zida kuti zisagwiritsidwe ntchito mphamvu.
Zofunikira za OSHA zokhudzana ndi miyezo yowongolera mphamvu zoopsa zitha kupezeka mu 29.CFR.1910.147. Muyezo uwu umafuna olemba ntchito kuti apange mfundo za LOTO pakukonza ndi kukonza makina ndi zida, pamene kuyatsa kapena kuyambitsa makina kapena zida mwangozi, kapena kutulutsa mphamvu yosungidwa kungavulaze antchito. Olemba ntchito ayenera kupanga mapulani ndikugwiritsa ntchito njira zotetezera zida zoyenera zotsekera kapena kuyika ma tagi ku zida zolekanitsa mphamvu, ndikuletsa makina kapena zida kuti apewe kuyatsa mwangozi, kuyambitsa, kapena kutulutsa mphamvu kuti apewe kuvulala kwa antchito.
Chinthu chofunikira kwambiri pa dongosolo la LOTO ndi mfundo yolembedwa. Kuphatikiza apo, muyezo umafuna olemba ntchito kuti apange njira zowongolera mphamvu, zomwe zikutanthauza kuti njira zozimitsira ndi kukonza zida ziyenera kulembedwa. Mwachitsanzo, ngati chipangizo choziziritsira mpweya chikufunika kukonzedwa, njira yozimitsira magetsi iyenera kuphatikizapo dzina/malo a gulu lozimitsira magetsi ndi nambala ya gulu lozimitsira magetsi mu gululo. Ngati dongosololi lili ndi magwero angapo a mphamvu, ndiye kuti pulogalamu yowongolera iyenera kufotokoza njira yodzimitsira magetsi onse. Asanayambe ntchito pa makina kapena zida zotsekedwa kapena zolembedwa, antchito ayenera kutsimikizira kuti zidazo zachotsedwa ndipo zazima.
Zinthu zina zofunika kwambiri mu dongosolo la LOTO zikuphatikizapo kuphunzitsa antchito ndi kuwunika pafupipafupi njira za LOTO. Maphunziro amafunika popereka ntchito ndipo ayenera kuphatikizapo maphunziro ozindikira magwero amphamvu oopsa, mtundu ndi kuchuluka kwa mphamvu zomwe zilipo kuntchito, komanso njira ndi njira zofunika pakupatula mphamvu ndi kuwongolera. Pamene ntchito ikusintha, kukhazikitsa makina atsopano kapena kusintha kwa njira kungabweretse zoopsa zatsopano, maphunziro ena amafunika.
Kuyang'anira nthawi ndi nthawi ndi kuwunika kwa pachaka kwa njirazi kuti zitsimikizire kulondola kwa njirazi kapena kudziwa kusintha kapena kukonza komwe kuyenera kuchitidwa pa njirazi.
Mwiniwake wa malo ogwirira ntchito kapena woyendetsa galimoto ayeneranso kuganizira njira za LOTO za kontrakitala. Kontrakitala wakunja ayenera kugwiritsa ntchito njira zawo za LOTO pochita zinthu monga zamagetsi, HVAC, makina amafuta kapena zida zina. Nthawi iliyonse ogwira ntchito zakunja akachita zinthu zomwe zikukhudzidwa ndi kuchuluka ndi kugwiritsa ntchito muyezo wa LOTO, olemba ntchito omwe ali pamalopo ndi olemba ntchito akunja ayenera kuuzana za njira zawo zotsekera kapena zochotsera.
