Bakwabonelela ngenkonzo ethembekileyo emva kokuthengisa, kubandakanywa ukugcinwa kunye nenkxaso yokuqinisekiswa kwakhona. Ukusebenza nabavelisi abathembekileyo kunciphisa umngcipheko kwaye kuqinisekisa ukuba izixhobo zisebenza njengoko kulindelekile kwiindawo ezinobungozi.

Imibuzo yokubuza abavelisi malunga neziqinisekiso

Abathengi kufuneka babuze abavelisi imibuzo ethile malunga neziqinisekiso zokuqinisekisa ukuthotyelwa. Imibuzo ephambili ibandakanya:

• Zeziphi iziqinisekiso eziphethwe yimveliso (umz., UL, ATEX, IECEx)?
• Ngaba umenzi angabonelela ngoxwebhu oluqinisekisa ezi ziqinisekiso?
• Ngaba iimveliso zivavanyelwe iindawo ezithile ezinobungozi, njengeZone 1 okanye uMmandla wesi-2?
• Zeziphi iinkqubo zogcino okanye zokuqinisekisa kwakhona ezifunekayo?

Le mibuzo inceda abathengi benze izigqibo ezizizo kwaye bakhethe iimveliso ezihlangabezana neemfuno zabo zokusebenza.

Izatifikethi zokukhanya ezisebenza ngokuqhushumba, ezifana ne-UL, i-ATEX, kunye ne-IECEx, zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthotyelwa kweendawo ezinobungozi. Ezi zatifikethi azikhuseli abasebenzi kuphela kodwa zikwaphucula ukusebenza kakuhle. Umzekelo, isatifikethi se-IECEx sihambelana nemigangatho yokhuseleko yamazwe ngamazwe, ukunciphisa iindleko kunye nexesha labavelisi ngelixa begcina ukhuseleko. Ngokufanayo, ukuthotyelwa kwemigangatho ye-NEC kunye ne-ATEX ibalulekile kumashishini afana ne-oyile kunye negesi, apho ukukhanya okungenakuqhambuka kunciphisa imingcipheko kunye nokuphucula ukuthembeka.

Utyalo-mali kwizisombululo zokukhanyisa eziqinisekisiweyo zibonelela ngeenzuzo zexesha elide. Iinkqubo zobungqina bokuqhuma kwe-LED, umzekelo, unokunciphisa ukusetyenziswa kwamandla ukuya kuthi ga kwi-90% kwaye kuphele ukuya kwiiyure ze-100,000, ukunciphisa kakhulu iimfuno zokugcina. Abathengi kufuneka bahlale beqinisekisa iziqinisekiso kwaye bakhethe iimveliso ezivela kubavelisi abathembekileyo ukuqinisekisa ukhuseleko, ukuthobela, kunye nokuqina.

FAQ

1. Kuthetha ukuthini “ubungqina bokudubula” kwizibane zokusebenza?

Izibane zokusebenza ezinobungqina bokudubula ziyilelwe ukuthintela iintlantsi zangaphakathi okanye ubushushu ekuvutheni iigesi ezinokutsha, umphunga, okanye uthuli kwiindawo eziyingozi. Ezi zibane zihlangabezana nemigangatho engqongqo yokhuseleko ukuqinisekisa ukusebenza ngokukhuselekileyo kwiatmosphere ezinokuba neziqhushumbisi.

2. Abathengi banokusiqinisekisa njani isiqinisekiso semveliso?

Abathengi banokuqinisekisa iziqinisekiso ngokujonga ugcino-lwazi olusemthethweni olusuka kumaqumrhu eziqinisekiso afana ne-UL, ATEX, okanye IECEx. Ezi nkcukacha ziqinisekisa ukuthotyelwa kwemveliso kunye nokunyaniseka, ukuqinisekisa ukuba iyahlangabezana neemfuno zokhuseleko kwiindawo ezinobungozi.

3. Ngaba izatifikethi ezifana ne-UL kunye ne-ATEX ziyatshintsheka?

Hayi, izatifikethi ezifana ne-UL kunye ne-ATEX zingqale ngokwengingqi. I-UL isebenza kuMntla Melika, ngelixa i-ATEX inyanzelekile kwiManyano yaseYurophu. Amashishini asebenza kwihlabathi jikelele kufuneka athathele ingqalelo isiqinisekiso se-IECEx sokuthobela ngokubanzi.

4. Kutheni le nto ukuleyibhile okufanelekileyo kubalulekile kwizibane ezingaqhushumba?

Iileyibhile ezifanelekileyo zibonelela ngolwazi olubalulekileyo, olufana nokuhlelwa kwendawo enobungozi kunye nemigangatho yokuthotyelwa. Iqinisekisa ukuba abasebenzisi banokuchonga iimveliso ezifanelekileyo kwiindawo ezithile kwaye baphephe ukuphulwa komthetho.

5. Kufuneka ziqinisekiswe kangaphi izibane ezikhusela ukudubula?

Iishedyuli zokuphinda zinikwe iziqinisekiso ziyahluka ngomzimba woqinisekiso kunye nohlobo lwemveliso. Ukuhlolwa rhoqo kunye nokugcinwa kuqinisekisa ukuthotyelwa okuqhubekayo nemigangatho yokhuseleko, ukukhusela abasebenzi kunye nezixhobo ngokuhamba kwexesha.
