• Yiziphi izinqubo zokulungisa noma zokuvuselela ezidingekayo?

Le mibuzo isiza abathengi ukuthi benze izinqumo ezinolwazi futhi bakhethe imikhiqizo ehlangabezana nezidingo zabo zokusebenza.

Izitifiketi zezibani zomsebenzi ezingaqhumi, njenge-UL, i-ATEX, kanye ne-IECEx, zidlala indima ebalulekile ekuqinisekiseni ukuphepha nokuthobela imithetho ezindaweni eziyingozi. Lezi zitifiketi azigcini nje ngokuvikela abasebenzi kodwa futhi zithuthukisa ukusebenza kahle. Isibonelo, isitifiketi se-IECEx sihambisana nezindinganiso zokuphepha zomhlaba wonke, sinciphisa izindleko nesikhathi sabakhiqizi ngenkathi sigcina ukuphepha. Ngokufanayo, ukuthobela amazinga e-NEC kanye ne-ATEX kubalulekile ezimbonini ezifana nowoyela negesi, lapho ukukhanya okuvimbela ukuqhuma kunciphisa izingozi futhi kuthuthukisa ukuthembeka.

Ukutshala imali ezixazululweni zokukhanyisa eziqinisekisiwe kunikeza izinzuzo zesikhathi eside. Izinhlelo ze-LED ezingaqhumi, isibonelo, zinganciphisa ukusetshenziswa kwamandla ngamaphesenti angama-90 futhi zihlale amahora afinyelela ku-100,000, okunciphisa kakhulu izidingo zokulungisa. Abathengi kufanele baqinisekise njalo izitifiketi futhi bakhethe imikhiqizo evela kubakhiqizi abathembekile ukuqinisekisa ukuphepha, ukuthobela imithetho, kanye nokuqina.

Imibuzo Evame Ukubuzwa

1. Kusho ukuthini ukuthi “akunakuqhuma” ngezibani zomsebenzi?

Izibani zomsebenzi ezingaqhumi zenzelwe ukuvimbela izinhlansi zangaphakathi noma ukushisa ekushiseni amagesi avuthayo, umusi, noma uthuli ezindaweni eziyingozi. Lezi zibani zihlangabezana nezindinganiso zokuphepha eziqinile ukuqinisekisa ukusebenza okuphephile ezindaweni ezingase ziqhume.

2. Abathengi bangaqinisekisa kanjani isitifiketi somkhiqizo?

Abathengi bangaqinisekisa izitifiketi ngokuhlola izizindalwazi ezisemthethweni ezivela ezinhlanganweni zezitifiketi ezifana ne-UL, i-ATEX, noma i-IECEx. Lezi ziqondisi ziqinisekisa ukuhambisana nomkhiqizo kanye nobuqiniso bawo, ziqinisekisa ukuthi uhlangabezana nezidingo zokuphepha ezindaweni eziyingozi.

3. Ingabe izitifiketi ezifana ne-UL kanye ne-ATEX zingashintshwa?

Cha, izitifiketi ezifana ne-UL kanye ne-ATEX ziqondene nesifunda. I-UL isebenza eNyakatho Melika, kanti i-ATEX iyimpoqo e-European Union. Amabhizinisi asebenza emhlabeni wonke kufanele acabangele isitifiketi se-IECEx ukuze alandele imithetho ebanzi.

4. Kungani ukulebula okufanele kubalulekile ezibanini ezingaqhumi?

Ukubhala amalebula ngendlela efanele kunikeza ulwazi olubalulekile, njengokuhlukaniswa kwezindawo eziyingozi kanye nezindinganiso zokuthobela imithetho. Kuqinisekisa ukuthi abasebenzisi bangakwazi ukubona imikhiqizo efanelekile ezindaweni ezithile futhi bagweme ukwephulwa kwemithetho.

5. Izibani ezingaqhumi kufanele ziqinisekiswe kangaki?

Amashejuli okuvuselelwa kabusha ayahlukahluka ngokuya ngenhlangano yesitifiketi kanye nohlobo lomkhiqizo. Ukuhlolwa njalo nokugcinwa kuqinisekisa ukuhambisana okuqhubekayo nezindinganiso zokuphepha, kuvikela abasebenzi kanye nemishini ngokuhamba kwesikhathi.
