Yintoni uMgangatho we-EN ISO 20471?

Umgangatho we-EN ISO 20471 yinto uninzi lwethu olunokuthi lwadibana nayo ngaphandle kokuqonda ngokupheleleyo ukuba ithetha ukuthini okanye kutheni ibalulekile. Ukuba ukhe wambona umntu onxibe ivesti enemibala eqaqambileyo ngelixa esebenza endleleni, kufutshane netrafikhi, okanye ekukhanyeni okuphantsi, maninzi amathuba okuba impahla yakhe ibambelele kulo mgangatho ubalulekileyo. Kodwa yintoni kanye kanye i-EN ISO 20471, kwaye kutheni ibaluleke kangaka kukhuseleko? Masingene ngaphakathi kwaye siphonononge yonke into oyifunayo 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 phantsi kweemeko zokukhanya okuphantsi, njengasebusuku, okanye kwiimeko apho kukho ukuhamba kakhulu okanye ukubonakala kakubi. Yicinge njengeprothokholi yokhuseleko kwiwadi yakho-kanye njengokuba amabhanti ezihlalo ezihlalweni eyimfuneko kukhuseleko lwemoto, iimpahla ezithobelayo ze-EN ISO 20471 zibalulekile kukhuseleko lwasemsebenzini.

Ukubaluleka Kokubonakala
Eyona njongo iphambili yomgangatho we-EN ISO 20471 kukuphucula ukubonakala. Ukuba ukhe wasebenza kufuphi neenqwelo-mafutha, kumzi-mveliso, okanye kwindawo yokwakha, uyayazi indlela ekubaluleke ngayo ukubonwa ngokucacileyo ngabanye. Impahla ebonakala iphezulu iqinisekisa ukuba abasebenzi ababonwa nje kuphela, kodwa babonwa ukude yaye kuzo zonke iimeko—nokuba kusemini, ebusuku, okanye kwimozulu enenkungu. Kumashishini amaninzi, ukubonakala okufanelekileyo kunokuba ngumahluko phakathi kobomi nokufa.

Isebenza njani i-EN ISO 20471?
Ke, isebenza njani i-EN ISO 20471? Konke kuhla kuyilo kunye nezixhobo zempahla. Umgangatho uchaza iimfuno ezithile zemathiriyeli ekhanyayo, imibala ye-fluorescent, kunye neempawu zoyilo ezandisa ukubonakala. Umzekelo, iimpahla ezithobela i-EN ISO 20471 zihlala zibandakanya imicu ebonisayo enceda abasebenzi bagqame ngokuchasene nendalo engqongileyo, ngakumbi kwiindawo ezinokukhanya okuphantsi.
Impahla ihlelwe kwiiklasi ezahlukeneyo ngokusekelwe kwinqanaba lokubonakala elinikeziweyo. Udidi lwe-1 lunikeza ukubonakala okuncinci, ngelixa i-Class 3 ibonelela ngeyona nqanaba eliphezulu lokubonakala, elihlala lifuneka kubasebenzi abajongene neendawo ezinomngcipheko ophezulu njengeendlela ezihamba phambili.

Izixhobo zeMpahla eZibonakala kakhulu
Impahla ebonakalayo ephezulu ibandakanya indibaniselwano yei-fluorescentizixhobo kunyeukubuyisela umvaizixhobo. Imibala ekhanyayo—enjengeorenji eqaqambileyo, emthubi, okanye eluhlaza—isetyenziswa ngenxa yokuba ibalasele emini nokukhanya okuphantsi. Izinto ezibuyisela umva, kwelinye icala, zibuyisela ukukhanya kumthombo wayo, oluncedo ngakumbi ebusuku okanye kwiimeko ezimnyama xa izibane zemoto okanye izibane zesitrato zinokwenza lowo unxibileyo abonakale ekude.

Amanqanaba oMbono kwi-EN ISO 20471
I-EN ISO 20471 ihlela iimpahla ezibonakalayo eziphezulu zibe ngamacandelo amathathu ngokusekwe kwiimfuno zokubonakala:
Iklasi yoku-1: Ubuncinci bomgangatho wokubonakala, oqhele ukusetyenziswa kwiindawo ezinomngcipheko ophantsi, njengendawo yokugcina impahla okanye imigangatho yefektri. Olu didi lufanelekile kubasebenzi abangabonakali kwi-traffic high-speed okanye izithuthi ezihambayo.
Iklasi yesi-2: Yenzelwe indawo ezinomngcipheko ophakathi, njengabasebenzi abasecaleni kwendlela okanye abasebenzi bokuhambisa. Ibonelela ngokhuseleko kunye nokubonakala ngakumbi kunoKlasi loku-1.
Iklasi yesi-3: Inqanaba eliphezulu lokubonakala. Oku kuyadingeka kubasebenzi abakwiindawo ezinobungozi obukhulu, njengeendawo zokwakha iindlela okanye abaphenduli bexakeka abafuna ukubonwa ukusuka kude, nakwiimeko ezimnyama.

Ngubani ofuna i-EN ISO 20471?
Usenokuba uyazibuza, "Ngaba i-EN ISO 20471 yeyabantu abasebenza ezindleleni okanye kwiindawo zokwakha?" Nangona aba basebenzi bephakathi kwamaqela acacileyo axhamla kwiimpahla ezibonakalayo eziphezulu, umgangatho usebenza kuye nabani na osebenza kwiimeko ezinokuba yingozi. Oku kuquka:
•Abalawuli bezithuthi
•Abasebenzi bokwakha
•Abasebenzi bexesha likaxakeka
•Abasebenzi kwisikhululo seenqwelomoya
•Abaqhubi bonikezelo
Nabani na osebenza kwiindawo apho kufuneka abonwe ngokucacileyo ngabanye, ngakumbi izithuthi, banokuzuza ngokunxiba izixhobo ezihambelana ne-EN ISO 20471.

I-EN ISO 20471 vs. Eminye iMigangatho yoKhuseleko
Ngelixa i-EN ISO 20471 yamkelwa ngokubanzi, kukho eminye imigangatho yokhuseleko kunye nokubonakala emsebenzini. Umzekelo, i-ANSI/ISEA 107 ngumgangatho ofanayo osetyenziswa eUnited States. Le migangatho inokwahluka kancinci ngokwemigaqo, kodwa injongo ihlala ifana: ukukhusela abasebenzi kwiingozi kunye nokuphucula ukubonakala kwabo kwiimeko ezinobungozi. Umahluko ophambili ulele kwimimiselo yengingqi kunye namashishini athile umgangatho ngamnye osebenza kuwo.

Indima yoMbala kwiZixhobo eziBonakalayo ngokuPhezulu
Xa kuziwa kwimpahla ebonakala iphezulu, umbala awuyonto nje yefashoni. Imibala ekhanyayo—enjengeorenji, tyheli, noluhlaza—ikhethwa ngenyameko kuba yona ibalasele ngakumbi ebudeni bemini. Le mibala ingqinwe ngokwenzululwazi ukuba ibonakala emini, naxa ingqongwe ngeminye imibala.
Okuchasene,imathiriyeli yokubuyisela umvazihlala ziyisilivere okanye zingwevu kodwa zenzelwe ukubuyisela ukukhanya kumthombo wako, ukuphucula ukubonakala ebumnyameni. Xa zidityanisiwe, ezi zinto zimbini zenza umqondiso onamandla obonakalayo onceda ukukhusela abasebenzi kwiindawo ezahlukeneyo.
