Yintoni i-EN ISO 20471 Standard?

Umgangatho we-EN ISO 20471 yinto abaninzi bethu abanokuyifumana bengayiqondanga ngokupheleleyo intsingiselo yawo okanye isizathu sokuba ubaluleke. Ukuba ukhe wambona umntu enxibe ijazi elinemibala eqaqambileyo ngelixa esebenza endleleni, kufutshane neemoto, okanye kwiimeko zokukhanya okuphantsi, kukho ithuba elihle lokuba impahla yakhe inamathele kulo mgangatho ubalulekileyo. Kodwa yintoni kanye kanye i-EN ISO 20471, kwaye kutheni ibaluleke kangaka kukhuseleko? Masingene kwaye sihlolisise yonke into ekufuneka uyazi malunga nalo mgangatho ubalulekileyo.

Yintoni i-EN ISO 20471?
I-EN ISO 20471 ngumgangatho wamazwe ngamazwe ochaza iimfuno zempahla ebonakala kakhulu, ngakumbi kubasebenzi abafuna ukubonwa kwiindawo ezinobungozi. Yenzelwe ukuqinisekisa ukuba abasebenzi babonakala kwiimeko eziphantsi kokukhanya, njengasebusuku, okanye kwiimeko apho kukho ukuhamba okuninzi okanye ukungabonakali kakuhle. Cinga ngayo njengenkqubo yokhuseleko kwikhabhathi yakho—njengoko iibhanti zezihlalo zibalulekile kukhuseleko lwemoto, impahla ehambelana ne-EN ISO 20471 ibalulekile kukhuseleko lwendawo yokusebenza.

Ukubaluleka Kokubonakala
Injongo ephambili yomgangatho we-EN ISO 20471 kukuphucula ukubonakala. Ukuba wakha wasebenza kufutshane neemoto, kumzi-mveliso, okanye kwindawo yokwakha, uyazi ukuba kubaluleke kangakanani ukubonwa ngokucacileyo ngabanye. Impahla ebonakala kakhulu iqinisekisa ukuba abasebenzi ababonwa nje kuphela, kodwa babonwa bekude nakuzo zonke iimeko—nokuba kusemini, ebusuku, okanye kwimozulu ebandayo. Kwimizi-mveliso emininzi, ukubonakala ngokufanelekileyo kunokuba ngumahluko phakathi kobomi nokufa.

Isebenza njani i-EN ISO 20471?
Ngoko ke, isebenza njani i-EN ISO 20471? Konke kuxhomekeke kuyilo kunye nezinto zempahla. Umgangatho uchaza iimfuno ezithile zezinto ezikhanyayo, imibala ekhanyayo, kunye neempawu zoyilo ezandisa ukubonakala. Umzekelo, impahla ehambelana ne-EN ISO 20471 iya kuhlala iquka imicu ekhanyayo enceda abasebenzi bahluke kwindawo engqongileyo, ingakumbi kwiindawo ezinokukhanya okuphantsi.
Impahla ihlulwe ngokweendidi ezahlukeneyo ngokusekelwe kwinqanaba lokubonakala elibonelelwayo. Udidi loku-1 lubonelela ngokubonakala okuncinci, ngelixa udidi lwesi-3 lubonelela ngenqanaba eliphezulu lokubonakala, elihlala lifuneka kubasebenzi abajongene neendawo ezinobungozi obukhulu njengeendlela ezinkulu.

Izinto Ezisetyenziswa Kwimpahla Ebonakala Kakhulu
Iimpahla ezibonakala kakhulu zihlala ziquka indibaniselwanoi-fluorescentizixhobo kunyeukuhlaziya ngasemvaizinto ezisetyenziswayo. Imibala ekhanyayo—efana neorenji eqaqambileyo, etyheli, okanye eluhlaza—isetyenziswa kuba iyabonakala emini nasekukhanyeni okuphantsi. Kwelinye icala, izinto ezibonisa ukukhanya zibuyisela ukukhanya kumthombo wazo, nto leyo eluncedo kakhulu ebusuku okanye kwiimeko ezimnyama xa izibane zemoto okanye izibane zesitalato zinokwenza umntu onxibe ukukhanya abonakale ekude.

Amanqanaba okubonakala kwi-EN ISO 20471
I-EN ISO 20471 ihlela impahla ebonakala kakhulu kwiindidi ezintathu ngokusekwe kwiimfuno zokubonakala:
Iklasi 1: Inqanaba elincinci lokubonakala, eliqhele ukusetyenziswa kwiindawo ezinomngcipheko omncinci, njengeendawo zokugcina impahla okanye umgangatho wefektri. Olu didi lufanelekile kubasebenzi abangakhange bachaphazeleke ziimoto ezihamba ngesantya esiphezulu okanye izithuthi ezihambayo.
Iklasi yesi-2: Yenzelwe iindawo ezinomngcipheko ophakathi, njengabasebenzi basecaleni kwendlela okanye abasebenzi bokuhambisa impahla. Inika ukugubungela nokubonakala okungaphezulu kuneKlasi yoku-1.
Iklasi yesi-3: Inqanaba eliphezulu lokubonakala. Oku kuyimfuneko kubasebenzi abakwiindawo ezinobungozi obukhulu, njengeendawo zokwakha iindlela okanye abo basabela kwiimeko zikaxakeka abafuna ukubonwa bekude, nokuba kwiimeko ezimnyama kakhulu.

Ngubani ofuna i-EN ISO 20471?
Usenokuba uzibuza, "Ingaba i-EN ISO 20471 yenzelwe abantu abasebenza ezindleleni okanye kwiindawo zokwakha kuphela?" Nangona aba basebenzi bephakathi kwamaqela acacileyo axhamla kwiimpahla ezibonakala kakhulu, umgangatho usebenza kuye nabani na osebenza kwiimeko ezinokuba yingozi. Oku kuquka:
• Abalawuli bezithuthi
•Abasebenzi bokwakha
•Abasebenzi bexesha likaxakeka
•Abasebenzi basemhlabathini kwisikhululo seenqwelo-moya
•Abaqhubi bokuhambisa izinto
Nabani na osebenza kwiindawo apho kufuneka abonwe ngokucacileyo ngabanye, ingakumbi izithuthi, unokungenelwa kukunxiba izixhobo ezihambelana ne-EN ISO 20471.

I-EN ISO 20471 xa ithelekiswa neminye imigangatho yokhuseleko
Nangona i-EN ISO 20471 yamkelwe ngokubanzi, kukho eminye imigangatho yokhuseleko nokubonakala kwindawo yokusebenza. Umzekelo, i-ANSI/ISEA 107 ngumgangatho ofanayo osetyenziswa eMelika. Le migangatho inokwahluka kancinci ngokweenkcukacha, kodwa injongo ihlala ifana: ukukhusela abasebenzi kwiingozi nokuphucula ukubonakala kwabo kwiimeko eziyingozi. Umahluko ophambili ukwimigaqo yengingqi kunye namashishini athile asebenza kuwo umgangatho ngamnye.

Indima yoMbala kwiZixhobo eziBonakalayo
Xa kufikwa kwimpahla ebonakala kakhulu, umbala awuyonto nje yefashoni. Imibala ekhanyayo—efana neorenji, etyheli, neluhlaza—ikhethwa ngononophelo kuba igqama kakhulu emini. Le mibala iye yangqinwa ngokwesayensi ukuba ibonakala emini, nokuba ijikelezwe zezinye imibala.
Okuchasene,izixhobo zokubonakalisa umvaZidla ngokuba zisilivere okanye zingwevu kodwa zenzelwe ukubuyisa ukukhanya kumthombo wako, nto leyo ephucula ukubonakala ebumnyameni. Xa zidityanisiwe, ezi zinto zimbini zenza uphawu olubonakalayo olunamandla olunceda ekukhuseleni abasebenzi kwiindawo ezahlukeneyo.
