Umutekano w'amashanyarazi mu kazi

Umutekano w'amashanyarazi mu kazi

Ubwa mbere, ndumva logique yibanze ya NFPA 70E kubyerekeye gukoresha amashanyarazi neza: mugihe hariho Shock Hazard, inzira nziza yo kurinda umutekano ni uguhagarika burundu amashanyarazi kandiGufunga tagout
Gukora "amashanyarazi akoreshwa neza"

Ni ubuhe buryo bw'amashanyarazi butekanye?

Leta aho umuyoboro w'amashanyarazi cyangwa igice cyumuzunguruko cyahagaritswe kuva ibice 10, Byageragejwe kugirango hamenyekane niba nta voltage ihari, kandi, nibiba ngombwa, ishingiye ku gihe gito kugirango irengere abakozi.

Kugirango habeho umutekano wibikorwa byo gupima ibikoresho byamashanyarazi cyangwa kubungabunga, mubyukuri nuburyo bwiza bwo guhagarika amashanyarazi, ariko tugomba gukora imirimo myinshi mubuzima, kandi namara gutsindwa amashanyarazi bizatera igihombo kinini ;Izi manza zidasanzwe zasobanuwe mubisanzwe, tuzabiganiraho nyuma.

Iyo abakozi ba EHS bashizeho umutekano w'amashanyarazi cyangwa uburyo bukora bwo gukora,
Amategeko agomba gukurikiza agomba kuba "gukuramo imbaraga nkuburyo bwa mbere".
NFPA 70E, INGINGO YA 110 Ibisabwa muri rusange kubikorwa byakazi bijyanye n’umutekano w’amashanyarazi, bitanga ibyifuzo byuburyo bwo gushyiraho uburyo bwo kwirinda amashanyarazi.Ibisabwa birambuye birakorwa muburyo bwo kwirinda amashanyarazi, ibisabwa mumahugurwa, inshingano zumukoresha naba rwiyemezamirimo, ibikoresho byo gupima amashanyarazi nibikoresho, hamwe nabashinzwe kumeneka.

Dore ibyo nabonye bishimishije:

Umuntu wujuje ibyangombwa (muri rusange byitwa Umuntu wabiherewe uburenganzira) ntabwo yujuje ibyangombwa nyuma yimyitozo yoroshye, kubera ko Umuntu akeneye kugerageza cyangwa gusana ibikoresho bizima kandi ashobora kwinjira mukarere ka Restrited Approach Boundary, gafite amahirwe menshi yo guhura na Arc Flash.Igipimo rero gifite ibisabwa birambuye kubakozi babishoboye.
Umuntu wujuje ibyangombwa agomba kuba ashoboye kumenya ibice bizima nicyo voltage aricyo, kandi akumva intera yumutekano yiyi voltage, hanyuma agahitamo urwego rukwiye rwa PPE.Ndabyumva byoroshye nuko usibye kubona uruhushya rwamashanyarazi, bagomba no guhabwa amahugurwa yihariye avuye muruganda bagatsinda ikizamini, kandi abakozi nkabo bagomba kongera gusuzumwa buri mwaka.
Mugihe cyo kugerageza ibice bizima bishobora kurenga 50V, ubunyangamugayo bwigikoresho cyikizamini bugomba kugenwa kuri voltage izwi mbere na nyuma ya buri kizamini.
