Chitetezo cha Magetsi Kuntchito

Chitetezo cha Magetsi Kuntchito

Choyamba, ndikumvetsa mfundo zazikulu za NFPA 70E pankhani yogwiritsa ntchito magetsi motetezeka: pamene pali ngozi ya Shock, njira yabwino yotsimikizira chitetezo ndikutseka magetsi onse ndiChizindikiro cha Lockout
Kupanga "malo ogwirira ntchito otetezeka pamagetsi"

Kodi Chitetezo cha Magetsi N'chiyani?

Mkhalidwe umene kondakitala wamagetsi kapena gawo la dera latsekedwa kuchokera ku zigawo 10, Kuyesedwa kuti kutsimikizire kusakhalapo kwa magetsi, ndipo, ngati kuli kofunikira, Kukhazikika kwakanthawi kuti ateteze antchito.

Pofuna kuonetsetsa kuti ntchito yoyesa kapena kukonza zida zamagetsi ndi yotetezeka, ndiyo njira yabwino kwambiri yochepetsera magetsi, koma tiyenera kuchita ntchito zambiri pansi pa mikhalidwe yamoyo, ndipo magetsi akangolephera kuwononga kwambiri; Milandu yapaderayi yafotokozedwa mu muyezo, womwe tidzakambirana mtsogolo.

Ogwira ntchito ku EHS akakhazikitsa njira zotetezera magetsi kapena zogwirira ntchito,
Lamulo loti litsatidwe liyenera kukhala "kuchotsa mphamvu ngati chisankho choyamba".
NFPA 70E, NKHANI 110 Zofunikira Zonse pa Machitidwe Ogwira Ntchito Okhudzana ndi Chitetezo cha Magetsi, imapereka malangizo a momwe mungakhazikitsire njira za Chitetezo cha Magetsi. Zofunikira mwatsatanetsatane zimaperekedwa pa njira zachitetezo chamagetsi, zofunikira pa maphunziro, maudindo a olemba ntchito ndi makontrakitala, zida zoyesera zamagetsi ndi malo, komanso zoteteza kutayikira kwa madzi.

Izi ndi zomwe ndapeza zosangalatsa:

Munthu Woyenerera (wodziwika kuti Munthu Wovomerezeka) sakhala Woyenerera atangophunzitsidwa pang'ono, chifukwa Munthuyo ayenera kuyesa kapena kukonza zida zamoyo ndipo angalowe m'dera la Restrited Approach Boundary, lomwe lili ndi mwayi waukulu wokhudzana ndi Arc Flash. Chifukwa chake muyezowu uli ndi zofunikira mwatsatanetsatane kwa ogwira ntchito oyenerera.
Munthu woyenerera ayenera kukhala wokhoza kuweruza ziwalo zamoyo ndi mphamvu yamagetsi, ndikumvetsetsa mtunda wotetezeka wa mphamvu yamagetsi iyi, ndikusankha mulingo woyenera wa PPE moyenerera. Kumvetsetsa kwanga kosavuta ndikuti kuwonjezera pa kupeza chilolezo cha wamagetsi, ayeneranso kulandira maphunziro apadera kuchokera ku fakitale ndikupambana mayeso, ndipo antchito otere ayenera kuyesedwanso chaka chilichonse.
Poyesa zida zamoyo zomwe zingapitirire 50V, umphumphu wa chida choyesera uyenera kutsimikiziridwa pa voltage yodziwika bwino musanayambe komanso mutatha kuyesa kulikonse.
