Liyini izinga le-EN ISO 20471?

Izinga le-EN ISO 20471 liyinto abaningi bethu okungenzeka bahlangabezane nayo ngaphandle kokuqonda ngokugcwele ukuthi lisho ukuthini noma kungani libalulekile. Uma uke wabona umuntu ogqoke ivesti elinemibala egqamile ngesikhathi esebenza emgwaqeni, eduze kwethrafikhi, noma ngaphansi kwezimo ezikhanyayo, maningi amathuba okuthi izingubo zakhe zinamathele kuleli zinga elibalulekile. Kodwa yini ngempela i-EN ISO 20471, futhi kungani ibaluleke kangaka ekuphepheni? Masingene sihlole konke odinga ukukwazi mayelana naleli zinga elibalulekile.

Iyini i-EN ISO 20471?
I-EN ISO 20471 iyindinganiso yamazwe ngamazwe ecacisa izidingo zezingubo ezibonakala kakhulu, ikakhulukazi kubasebenzi abadinga ukubonakala ezindaweni eziyingozi. Idizayinelwe ukuqinisekisa ukuthi abasebenzi babonakala ezimeni zokukhanya okuphansi, njengasebusuku, noma ezimeni lapho kunokunyakaza okuningi noma kungabonakali kahle. Kubheke njengomthetho wokuphepha wekhabethe lakho—njengoba nje amabhande ezihlalo ebalulekile ekuphepheni kwemoto, izingubo ezithobela i-EN ISO 20471 zibalulekile ekuphepheni emsebenzini.

Ukubaluleka Kokubonakala
Inhloso enkulu yezinga le-EN ISO 20471 ukuthuthukisa ukubonakala. Uma uke wasebenza eduze kwethrafikhi, efektri, noma endaweni yokwakha, uyazi ukuthi kubaluleke kangakanani ukubonwa abanye ngokucacile. Izingubo ezibukeka kahle ziqinisekisa ukuthi abasebenzi ababonwa nje kuphela, kodwa babonwa kude nakuzo zonke izimo—kungakhathaliseki ukuthi kusemini, ebusuku, noma esimweni sezulu esinenkungu. Ezimbonini eziningi, ukubonakala okufanele kungaba umehluko phakathi kokuphila nokufa.

Isebenza kanjani i-EN ISO 20471?
Ngakho-ke, i-EN ISO 20471 isebenza kanjani? Konke kuncike ekuklanyweni nasezintweni zokugqoka. Izinga lichaza izidingo ezithile zezinto ezikhanyayo, imibala ye-fluorescent, nezici zedizayini ezikhulisa ukubonakala. Isibonelo, izingubo ezithobela i-EN ISO 20471 ngokuvamile zizofaka imichilo ekhanyayo esiza abasebenzi bagqame uma beqhathaniswa nendawo ezungezile, ikakhulukazi ezindaweni ezinokukhanya okuphansi.
Izingubo zihlukaniswe ngamakilasi ahlukene ngokusekelwe ezingeni lokubonakala elinikeziwe. Ikilasi 1 linikeza ukubonakala okuncane, kuyilapho Ikilasi 3 linikeza izinga eliphezulu kakhulu lokubonakala, elivame ukudingeka kubasebenzi abachayeke ezindaweni ezinobungozi obuphezulu njengemigwaqo emikhulu.

Izingxenye Zezingubo Ezibonakala Kakhulu
Izingubo ezibukeka kahle ngokuvamile zihlanganisa inhlanganisela yei-fluorescentizinto zokwakha kanyei-retroreflectiveizinto zokwakha. Imibala ekhanyayo—njengowolintshi ogqamile, ophuzi, noma oluhlaza—isetshenziswa ngoba igqama emini nasemini. Ngakolunye uhlangothi, izinto ezibonisa ukukhanya zibuyisela ukukhanya emthonjeni wako, okusiza kakhulu ebusuku noma ezimeni ezilufifi lapho izibani zezimoto noma izibani zasemgwaqweni zingenza lowo oyigqokile abonakale ekude.

Amazinga Okubonakala ku-EN ISO 20471
I-EN ISO 20471 ihlukanisa izingubo ezibonakala kakhulu ngezigaba ezintathu ngokuya ngezidingo zokubonakala:
Ikilasi 1: Izinga eliphansi lokubonakala, ngokuvamile elisetshenziselwa izindawo ezinengcuphe encane, njengezindawo zokugcina impahla noma amaphansi efekthri. Leli klasi lilungele izisebenzi ezingavezwanga kuthrafikhi ezihamba ngesivinini esiphezulu noma ezimotweni ezihambayo.
Ikilasi lesi-2: Idizayinelwe izindawo ezinobungozi obumaphakathi, njengabasebenzi abaseceleni komgwaqo noma abasebenzi bokulethwa kwezidingo. Inikeza ukufakwa okwengeziwe nokubonakala kune-Class 1.
Ikilasi lesi-3: Izinga eliphezulu lokubonakala. Lokhu kuyadingeka kubasebenzi abasezindaweni ezisengozini enkulu, njengezindawo zokwakha imigwaqo noma abaphenduli bezimo eziphuthumayo abadinga ukubonwa ezindaweni ezikude, ngisho nasezimeni ezimnyama kakhulu.

Ngubani Odinga i-EN ISO 20471?
Ungase uzibuze, "Ingabe i-EN ISO 20471 ingeyabantu abasebenza emigwaqweni noma ezindaweni zokwakha kuphela?" Nakuba lezi zisebenzi ziphakathi kwamaqembu asobala kakhulu ahlomula ngezingubo ezibonakala kahle, izinga lisebenza kunoma ubani osebenza ngaphansi kwezimo ezingase zibe yingozi. Lokhu kuhlanganisa:
•Izilawuli zethrafikhi
•Abasebenzi bokwakha
•Abasebenzi bezimo eziphuthumayo
•Abasebenzi basesikhumulweni sezindiza
•Abashayeli bokulethwa
Noma ubani osebenza ezindaweni lapho edinga ukubukwa ngokucacile kwabanye, ikakhulukazi izimoto, angazuza ngokugqoka igiya elithobela i-EN ISO 20471.

I-EN ISO 20471 vs. Amanye Amazinga Okuphepha
Nakuba i-EN ISO 20471 yaziwa kabanzi, akhona amanye amazinga okuphepha nokubonakala emsebenzini. Isibonelo, i-ANSI/ISEA 107 iyindinganiso efanayo esetshenziswa e-United States. Lawa mazinga angase ahluke kancane ngokwezicaciso, kodwa umgomo uhlala unjalo: ukuvikela abasebenzi ezingozini nokuthuthukisa ukubonakala kwabo ezimeni eziyingozi. Umehluko oyinhloko useziqondisweni zesifunda kanye nezimboni ezithile izinga ngalinye elisebenza kuzo.

Iqhaza Lombala Egiyeni Elibonakala Kakhulu
Uma kuziwa ezimpahleni ezibonakalayo eziphezulu, umbala ungaphezu nje kwesitatimende semfashini. Imibala ekhanyayo—njengowolintshi, ophuzi, noluhlaza—ikhethwa ngokucophelela ngoba igqama kakhulu emini. Le mibala ifakazelwe ngokwesayensi ukuthi ibonakala emini, noma izungezwe eminye imibala.
Ngokungqubuzanayo,izinto ezibuyisela emuvangokuvamile ziyisiliva noma ezimpunga kodwa zenzelwe ukubuyisela ukukhanya emthonjeni wako, ukuthuthukisa ukubonakala ebumnyameni. Uma zihlanganisiwe, lezi zakhi ezimbili zenza isignali enamandla ebonakalayo esiza ukuvikela abasebenzi kuzilungiselelo ezihlukahlukene.
