Ukuphepha Kukagesi Emsebenzini

Ukuphepha Kukagesi Emsebenzini

Okokuqala, ngiyaqonda ukuthi i-NFPA 70E inengqondo kangakanani mayelana nokusetshenziswa kukagesi okuphephile: uma kukhona i-Shock Hazard, indlela engcono kakhulu yokuqinisekisa ukuphepha ukuvala ngokuphelele ugesi kanyeIthegi yokukhiya ngaphandle
Ukudala “izimo zokusebenza eziphephile zikagesi”

Siyini Isimo Sokusebenza Esiphephile Ngogesi?

Isimo lapho umqhubi kagesi noma ingxenye yesekethe inqanyuliwe ezingxenyeni eziyi-10, Kuhlolwe ukuqinisekisa ukungabikho kwe-voltage, futhi, uma kudingeka, Kumiswe okwesikhashana ukuze kuvikelwe abasebenzi.

Ukuze kuqinisekiswe ukuphepha kokuhlolwa noma umsebenzi wokulungisa imishini kagesi, kuyindlela engcono kakhulu yokunqamula ukunikezwa kwamandla kagesi, kodwa kufanele senze umsebenzi omningi ngaphansi kwezimo ezibukhoma, futhi uma ukwehluleka kwamandla kuzobangela ukulahlekelwa okukhulu; Lawa macala akhethekile achazwe endinganisweni, esizoxoxa ngayo kamuva.

Uma abasebenzi be-EHS besungula izinqubo zokuphepha kagesi noma zokusebenza bukhoma,
Umthetho okufanele ulandelwe kumele ube “ukususa ugesi njengokukhetha kokuqala”.
I-NFPA 70E, ISIHLOKO 110 Izidingo Ezijwayelekile Zemikhuba Yokusebenza Ehlobene Nokuphepha Kukagesi, inikeza izincomo zendlela yokusungula izinqubo Zokuphepha Kukagesi. Kunezidingo ezinemininingwane zezinqubo zokuphepha kukagesi, izidingo zokuqeqeshwa, imisebenzi yomqashi kanye nosonkontileka, imishini yokuhlola kagesi kanye nezindawo, kanye nezivikelo zokuvuza.

Nakhu engikutholile kuthakazelisa:

Umuntu Ofanelekayo (ngokuvamile obizwa ngokuthi Umuntu Ogunyaziwe) akafaneleki ngemva kokuqeqeshwa okulula, ngoba Umuntu udinga ukuhlola noma ukulungisa imishini ephilayo futhi angangena endaweni ye-Restrited Approach Boundary, enethuba elikhulu lokuxhumana ne-Arc Flash. Ngakho-ke indinganiso inezidingo eziningiliziwe zabasebenzi abafanelekile.
Umuntu ofanelekayo kumele akwazi ukwahlulela ukuthi yiziphi izingxenye eziphilayo nokuthi iyini i-voltage, futhi aqonde ibanga eliphephile lale voltage, bese ekhetha izinga elifanele le-PPE ngokufanele. Ukuqonda kwami ​​okulula ukuthi ngaphezu kokuthola ilayisensi yochwepheshe kagesi, kufanele futhi athole ukuqeqeshwa okukhethekile efektri futhi aphumelele ukuhlolwa, futhi abasebenzi abanjalo kumele bahlolwe kabusha njalo ngonyaka.
Uma kuhlolwa izingxenye eziphilayo ezingase zidlule ama-V angu-50, ubuqotho bethuluzi lokuhlola kufanele bunqunywe nge-voltage eyaziwayo ngaphambi nangemva kokuhlolwa ngakunye.
