Ukukhetha indawo ebiyelwe kubalulekile uma kuziwa ekuqinisekiseni ukuphepha kwezindawo zezimboni, ikakhulukazi izindawo eziyingozi. Izindawo ezibiyelwe eziyingozi zenzelwe ukuvikela imishini kagesi emagesi aqhumayo, uthuli nezinye izici zemvelo. Lo mhlahlandlela uzokusiza ukuthi ubhekane nobunzima bokukhetha indawo ebiyelwe.indawo enobungozi ebiyelwelokho kulungele izidingo zakho ezithile.
Qonda indawo eyingozi
Ngaphambi kokungenela inqubo yokukhetha, kubalulekile ukuqonda ukuthi yini eyakha indawo eyingozi. Lezi zindawo zihlukaniswa ngokuya ngokuba khona kwamagesi avuthayo, umusi noma uthuli. Izinhlelo zokuhlukanisa zivame ukufaka:
- Indawo 0Indawo lapho igesi eqhumayo ikhona khona njalo noma isikhathi eside.
- Indawo 1: Indawo lapho umoya wegesi oqhumayo ungase uvele khona ngesikhathi sokusebenza okuvamile.
- Indawo 2: Isimo segesi esiqhumayo cishe asikwazi ukwenzeka ngesikhathi sokusebenza okuvamile, futhi uma singenzeka, sizoba khona isikhathi esifushane kuphela.
Indawo ngayinye idinga uhlobo oluthile lwendawo ebiyelwe ukuqinisekisa ukuphepha nokuhambisana nemithethonqubo.
Izinto Ezibalulekile Okufanele Uzicabangele Ekukhetheni Izindawo Eziyingozi Ezivalekile
1. Ukukhethwa Kwezinto Ezibalulekile
Izinto zesikhwama zibalulekile ekuqineni nasekuphepheni. Izinto ezivamile zifaka:
- Insimbi engagqwali: Inikeza ukumelana okuhle kakhulu nokugqwala, ilungele izindawo ezinzima.
- I-Aluminium: Ilula futhi ayigqwali, kodwa ingase ingafaneleki kuzo zonke izindawo eziyingozi.
- I-Polycarbonate: Inikeza ukumelana okuhle kokushayisana futhi ivame ukusetshenziswa ezindaweni ezingaba nzima kakhulu.
Ukukhetha izinto ezifanele kuzoncika ezingozini ezithile ezikhona endaweni okuyo.
2. Izinga Lokuvikela Ukungena (IP)
Isilinganiso se-IP sibonisa ikhono lendawo ebiyelwe lokumelana nothuli nokungena kwamanzi. Ezindaweni eziyingozi, isilinganiso se-IP esiphezulu sivame ukudingeka. Funa indawo ebiyelwe enesilinganiso se-IP okungenani se-IP65 ukuqinisekisa ukuvikelwa othulini kanye namajethi amanzi anomfutho ophansi.
3. Izindlela ezingaqhumi
Kunezindlela ezahlukene zokuvikela ukuqhuma ezitholakalayo, okuhlanganisa:
- Ayiqhumi (Ex d): Yakhelwe ukumelana nokuqhuma ngaphakathi kwendlu ebiyelwe futhi ivimbele amalangabi ukuba angaphumi.
- Ukuphepha Okuthuthukisiwe (Isib. e): Qinisekisa ukuthi imishini iklanyelwe ukunciphisa ingozi yomlilo.
- Ukuphepha Kwangaphakathi (Isib. i): Kunciphisa amandla atholakalayo okushisa, okwenza kufaneleke ukusetshenziswa kwe-Zone 0 kanye ne-Zone 1.
Ukuqonda lezi zindlela kuzokusiza ukuthi ukhethe indawo evalekile ehlangabezana nezidingo ezithile zezindawo eziyingozi.
4. Usayizi Nokucushwa
Indawo ebiyelwe kufanele ibe nosayizi ukuze ivumelane nemishini ngenkathi ivumela umoya ofanele kanye nokushabalalisa ukushisa. Cabanga ngendlela ofake ngayo bese uqinisekisa ukuthi indawo ebiyelwe ifinyeleleka kalula ukuze ilungiswe futhi ihlolwe.
5. Isitifiketi Nokuthobela Imithetho
Qiniseka ukuthi indawo ebiyelwe ihlangabezana nezindinganiso nezitifiketi ezifanele, njenge-ATEX (yaseYurophu) noma i-NEC (yase-United States). Lezi zitifiketi zibonisa ukuthi indawo ebiyelwe ihlolwe futhi ihlangabezana nezimfuneko zokuphepha ezindaweni eziyingozi.
6. Izimo zemvelo
Cabanga ngezimo zemvelo lapho ikhabhinethi izofakwa khona. Izici ezifana namazinga okushisa aphezulu, umswakama, kanye nokuchayeka kumakhemikhali kungathonya ukukhethwa kwezinto zokuvala kanye nomklamo.
Ekuphetheni
Ukukhetha okulungileindawo enobungozi ebiyelwekuyisinqumo esibalulekile esithinta ukuphepha nokuthobela imithetho ezindaweni zezimboni. Ngokucabanga ngezinto ezifana nokukhethwa kwezinto, isilinganiso se-IP, indlela yokuvikela ukuqhuma, usayizi, izitifiketi kanye nezimo zemvelo, ungenza isinqumo esinolwazi sokugcina abantu nemishini iphephile. Qiniseka ukuthi uthintana nochwepheshe futhi ulandela imithetho yendawo ukuqinisekisa ukuthi indawo yakho ebiyelwe ihlangabezana nazo zonke izindinganiso zokuphepha ezidingekayo.
