Ukufunda umbono wezindaba zase-EN zeziphepho zokusebenza ezivikela emvelo
Kumazwe okuphakeme kakhulu njengezindlela zokusebenza zokufaka amasimbi, ukugqibela kwamaphutha, izinhlangano zezinkulungwane nezinhlangano zokwakha amashiphi, izincwadi zokusebenza ezingenakwazi ukuzimela umoya ziyisibonelo esikhulu sokuvikela abasebenzi phansi kwemithombo yomoya, umthelelo, nokubuka kwamaphutha okukhala. Ngokusebenzisa izinsuku eziningi kunezinkulungwane ezimbili nezintathu, ngizibona indlela yokusebenza okungafani nesifundo kuyenza ukuthi abasebenzi bavulekile kumaqhamo okubhula kakhulu nokufelwa kokuhambisana nemiphumela yezinhlangano. Imiphumela yezinhlangano zaseYurophu EN 11611 ne-EN 11612 ziyizinhlangano eziphathelene nomkhakha wasezweni wonke ozivakalise iziphumo, izimboni, nezinhlangano zezincwadi zokuvikela. Abasemthethweni baseCEN (Komiti YaseYurophu Yokuvikela) bavuma ukuthi lezi zinhlangano ziyavikela ukuthi izincwadi zokusebenza ezingenakwazi ukuzimela umoya ziyabeka isibonelo sokuvikela ukuthi umoya ushale, ziyavikela ukuthi umthelelo uhlale, futhi ziyavikela ukuthi zingahleli noma zingadluli ngokushaya abasebenzi. Izincwadi zethu zokusebenza ezingenakwazi ukuzimela umoya ziyagcina izinhlangano zaseYurophu zombili, EN 11611 ne-EN 11612, ziyasebenzisa izimboni ezinkulu zasekhlabathi ukuthi zihambisane nemiphumela eyodwa yokuvikela. Ukuziqonda lezi zinhlangano kusiza izinhlangano ukukhetha ukuvikela okuphelele okuhambisana nemiphumela yezindawo zokusebenza.
Izinqakotho Zokusebenza Zokuphatha Kwe-EN 11611 Kwizicathulo Zokuphatha Kwezinye Izingxenye
I-EN 11611 yisistanda se-Europe esithile sokuphatha kwezicathulo zokuphatha kwezinye izingxenye ezisebenzisa ukubhala nokuthintana okunye. Iyasetshenzisa izimboni eziphelele zokuphatha kwezinye izingxenye, isikhathi sokuphatha emva kokubhala, isikhathi sokuphatha emva kokubhala kwezinye izingxenye, ukudala amaphuzu, nokuphatha kwezinye izingxenye zokubhala kwezinye izingxenye. Isistanda isibiza ukuthi isifuba asifanele ukubhala kuqanda, ukudala amaphuzu, noma ukwenza amaqanda amahlanu. Isikhathi sokuphatha emva kokubhala nasemva kokubhala kwezinye izingxenye akufanele ukuphikisa imizuzwana miyane. I-EN 11611 iyadela ukuphatha kwezinye izingxenye kuClass 1 neClass 2, obabili bayadlula ukuphatha kwezinye izingxenye okuphelele. Izicathulo zethu zokuphatha kwezinye izingxenye ziyafika futhi ziyakhulisa lezi zinqakotho ngokusebenzisa izifuba zokuphatha kwezinye izingxenye nezihlangothi zokubhala ezinamandla. Kusenqaba elikhulu lokubhala, izicathulo zethu ezinamandla kwe-EN 11611 zazisusa izinkinga zokubhala kakhulu futhi zaziphuma ngokuphelele kwezimboni zokuphatha kwezinye izingxenye zokusebenza. Lokhu sisitanda siyavumela ukuthi izicathulo ziyasebenza ngokuphelele phansi kweminye izinkambo zokubhala, izinkambo zokubhala, nokubhala okuphansi kwezinye izingxenye.
Izisombululo Zokuphatha Kwe-EN 11612 Zokubhala Kwamaphoyisa Okusebenza Okunamandla Kwemifula
I-EN 11612 yindlela eyinkimbinkimbi yase-Europe yokubhala kwamaphoyisa okusebenza okunamandla kwemifula, ekhathalela ukuvikela phakathi kwezindawo zokusebenza zezindustria ngokujwayelekile. Iyakhathalela ukuvikela phakathi kwe-heat yokuqhubeka, heat yokuqonda, heat yokuqondana, nokufika kwezilwane zomfula ozinamandla. Le ndlela iyisebenzisa isistimu sokubhala ngobugcwele: A kusukela ku-‘limited flame spread’ (kuyidingekile), B kusukela ku-‘convective heat’, C kusukela ku-‘radiant heat’, D kusukela ku-‘molten aluminum’, E kusukela ku-‘molten iron’, F kusukela ku-‘contact heat’. Ukuba kufanele kuhlanganise, amaphoyisa kufanele akhiphe isifundo sika-A futhi isifundo esinye ngaphezu kwalokho. Amaphoyisa okusebenza okunamandla kwethu ayinika ubukhulu bokuvikela obuhlelwe ngamaphoyisa amaningi ukuze ahlangele izinkinga ezahlukeneyo. Izinkambo zizocwaningwa ngokuthi ziyabona ukuthi zihamba njengoba kuzoba kusuka kwe-180°C, nokushrinking kufanele kubhekeka ngokulingana ne-5%. Izinqumo zokuvikela imifula nezidingo zokusebenza zokubhala kuzoba kuyinhloko yokuvikela nokuhlakanipha ngokuphakeme kusasa lomkhulu. Ukuthi kuhlanganise ne-EN 11612 kubonisa ukuthi kuyasebenza kumazwe okugcina umfula, okugcina umfula wokugcina, okugcina umfula wokugcina, nokusebenza kwezindustria.
Ukuthi Iziphakamiso Zethu Zokusebenza Ezinamandla Okukhanyisa Ziyakhuluma Namaqhezu Ama-2
Iziphakamiso zethu zokusebenza ezinamandla okukhanyisa zibhekiswe kusukela ukuthi zizame ukuphikisana ne-EN 11611 ne-EN 11612, kubonakalisa ukuthi kunezinkundla ezingaphezulu nokuziphatha ngokuhle nokubona ngokuphambuka. Sisebenzisa izihlangu esikhulu esingaphezulu esinamandla okukhanyisa (inherent) noma esithile kahle (durably treated) esinamandla okukhanyisa, esiqinisekisa ukuthi kunezinhlobo zokuvikela emva kokubuyiselwa kwezilungiselelo zokuchitha kwezindustria. Konke okubhekene nezinyathelo, izihlangu, iziphozo, nezinkampani zinamandla okukhanyisa ukuze sizimele amaphuzu aloba. Konke okubhekene nezibalo ziyachazwa emlabathini ngokukhanyisa kwezinyathelo, ukuthabatha kwezimoya, nokuvikela phansi kwemithwalo. Izirhwebhu zokuvikela ziqinisekisa ukuthi ziyasebenza ngokuphelele ngamaqhezu e-Europe. Isigaba sakuthu sokudesign sivikela ukuthi kunezinhlobo zokuvikela, ukuthabatha, nokufaka ngokuphelele ukuze kuboneke ukuthi kunezinhlobo zokuvikela zokushaya. Abathengi bethu basezindustria zokugqaza, izilwane zezinkabi, nezindustria zokugcina izilwane zokugcina zibonakala ngokuvikela kweziphakamiso zethu ezinamandla okukhanyisa ukuthi kunezinhlobo zokuvikela zokushaya. Ukuvikela okuphelele kunezinhlobo zokuvikela kunezinhlobo zokuvikela zokushaya.
Ukuvikela Okuphelele Nokuvikela Okuphelele Kwesikhathi Esidlonge Kweziphakamiso Zokusebenza Ezinamandla Okukhanyisa
Ukukhetha izipholo zokusebenza ezingenakwenzela umoya ozinamuhla okanye ukuzinikela kwezinye izinto ezinamuhla, ezifanayo ne-EN 11611 ne-EN 11612, kusinika isivumelwano esihle kubizinesi nezibhambe. Ukufanelela kusindisa amaphroblemi okugcina, kusula izindleko zokubhokha, futhi kusiza ekuphatheni imithombo yezimpendulo zokuphatha. Izipholo zokulondoloza ezihle kusiza ukuphawula ukuzinikela kwabantu abasebenza, kusula ukuguqula kwezibhambe, futhi kusiza ukuthuthukisa isiko sokulondoloza kwebizinesi. Isikhungo sakithi sokufanelela ngokuphelele sisenza ukuphatha kusisisekelo futhi sifanelele ngezimpendulo zabezinesi ngokuphelele emhlabeni wonke. Ngokuba kunezikhathi ezide zokusebenza futhi kunezinhlobo ezihle zokusebenza, izipholo zakithi zisiza ukusula izindleko zokunqoba ngokuphelele. Kusukela kusikhungo sakithi sokusiza ngokuphelele nokusiza ngokuphelele kwezinhlobo ezihle, sizisiza izibhambe ukwakha ukulondoloza kwezindawo zokusebenza. Kuzo zonke izibhambe eziphakeme kwezindawo zokuphakama kokuphakama komoya noma kwezindawo ezingenakwenzela umoya ozinamuhla, izipholo zokusebenza ezingenakwenzela umoya ozinamuhla ezifanayo ne-EN ayizingo zokulondoloza kuphela—kuyizindlela zokuhlanganisa isikhungo sokulondoloza, ukufanelela, nokuphatha kwezindawo zokusebenza.
