Izimpawu zokuphuma zibalulekile ezakhiweni, zisebenza njengemihlahlandlela ebonakalayo eqondisa abahlali emizileni yokuphuma ephephile ngesikhathi sezimo eziphuthumayo. Ukubaluleka kwazo kudlula nje ukuhambisana; zidlala indima ebalulekile ekuthonyeni ukuziphatha kwengqondo ezimweni eziphakeme zok压力 ezifana nezikhukhula, imililo, noma ukuhamba kukagesi. Lapho abahlali bebona uphawu lokuphuma olukhanyayo nolwakhiwe kahle, banelungelo lokuhlala bethule, benze izinqumo ezisheshayo, futhi baphume ngokuphepha. Ukuze uphawu lokuphuma lusebenza kahle, akukhona nje kuphela ukubonakala kwalo kodwa futhi nezimpawu ezamukelekayo emhlabeni jikelele kanye nobuchwepheshe bokukhanyisa obuqinisekisa ukuhamba ngisho nasezimo ezinzima.

Ukuguqulwa kwezimpawu zokuphuma kuhlobene kakhulu nezifundo ezitholakele ezimweni ezinzima zomlando. Omunye wemicimbi ebalulekile eyagcizelela isidingo sezimpawu zokuphuma ezicacile kwaba iTriangle Shirtwaist Factory Fire ngo-1911. Le ngwadla, eyaholela ekulahlekelweni okukhulu kokuphila, ingxenye ngenxa yokungabi nezimpawu zokuphuma ezanele kanye nezicabha ezivalekile, yakhuthaza izinguquko zokuphepha. Izimpawu zokuphuma zakuqala zazilula, ngokuvamile zibhaliwe noma ziprintiwe ngegama elithi "EXIT" ngamagama amakhulu. Nokho, lezi zinhlelo ezilula zaba nezinkinga zokubonakala, ikakhulukazi ngaphansi komlilo noma ezimeni zokukhanya okuphansi. Ngokuhamba kwesikhathi, isidingo sezimpawu zokuphuma ezikhanyayo nezicacile saba sobala. Le nqubekela phambili yaholela ekwamukelweni kwezobuchwepheshe bokukhanyisa obuhlukahlukene kanye nezinto ezikhanyayo ukuze kuthuthukiswe ukuqashelwa ezimweni eziphuthumayo.

Namuhla, izindinganiso zezimpawu zokuphuma ziphathwa yimithetho eqinile yamazwe omhlaba ukuze kuqinisekiswe ukuvumelana nokusebenza kahle. Lezi zindinganiso zikhomba usayizi, umbala, ukukhanya, nezimfuneko zokubeka ukuze kuqinisekiswe ukubonakala okuhle. Isibonelo, izindinganiso eziningi zanamuhla zidinga ukuthi izimpawu zokuphuma zikhanyiswe ngokuqhubekayo noma zibe ne-self-luminous, zisebenzisa ubuchwepheshe obufana nezimpawu zokuphuma ze-LED noma izinto ezikhanyayo ezikhanyayo ebumnyameni. Uhlelo lombala ngokuvamile luhlanganisa ukuhlanganiswa okuphakeme kokuphikisana njengemibhalo emhlophe emvelweni ebomvu noma eluhlaza, nakuba ezinye izizwe zinezinhlobo ezihlukile. Ngaphezu kwalokho, izindinganiso ziqinisekisa ukufakwa kwezikhombisi-zindlela lapho kudingeka ukuze kukhombise kahle izindlela zokuphuma. Ukuhambisana nalezi zindinganiso kubalulekile hhayi kuphela ukuze kuhlonishwe umthetho kodwa futhi ukuze kukhuphule ukuphepha ngesikhathi sezimo eziphuthumayo.

I-"Running Man" pictogram iye yaba uphawu olwaziwa emhlabeni jikelele olukhonjiswe ezimpahleni eziningi zokuphuma. Ivela kwi-International Organization for Standardization (ISO) ngeminyaka yama-1980, lo mkhono ubonisa isithombe esihlelwe kahle esihamba siye emnyango wokuphuma, sikhombisa ukuhamba. Ngokomqondo, lesi sithombe sihamba phambili futhi sidlula imingcele yolimi, sithuthukisa ukusebenza kahle ezindaweni eziningi. Isimo esisebenzayo sesithombe sikhuthaza umuzwa wokuphuthuma ngaphandle kokudala ukwesaba, sihamba abantu ngokuthula siye endaweni ephephile. Ukwamukelwa kwe-Running Man kuthuthukisile ukujula nokujwayeleka kwezimpahleni zokuphuma, okubaluleke kakhulu ezindaweni zomphakathi ezifana nezikhumulo zezindiza, izikhungo zokuthenga, nezakhiwo zamahhovisi.

Ngenkathi izindinganiso zomhlaba jikelele zinikeza uhlaka olujwayelekile, kunezinguquko ezibalulekile ezweni ngalinye emthethweni wezimpawu zokuphuma. E-United States, i-Occupational Safety and Health Administration (OSHA) kanye ne-National Fire Protection Association (NFPA) zibeka izindinganiso, zigcizelela izimpawu ezikhanyayo ezibomvu noma eziluhlaza ezinezinhlamvu ezicacile. I-U.S. iphinde ivumele ukusetshenziswa kwezimpawu zokuphuma ze-LED, ezinikeza ukusebenza kahle kwamandla nokuphila isikhathi eside. Ngasikhathi sinye, emazweni aseYurophu, ukusetshenziswa kwepictogram yeRunning Man ezizindeni eziluhlaza kuyavame kakhulu, kuhambisana nezindinganiso ze-ISO. Lezi zinguquko zibonisa izintandokazi zamasiko nezindlela zomlando zokuphepha kodwa ekugcineni zihlangana ngenhloso yokwenza kube lula ukubonwa nokuholwa okuthembekile ngesikhathi sezimo eziphuthumayo.

Canada kanye ne-Australia bakhe izindinganiso zabo zokuphuma ezihambisana kakhulu nezinhlelo ezinhle zomhlaba jikelele ngenkathi kufakwa nezidingo zokuphepha zendawo. Izindinganiso zaseCanada, ezilawulwa yi-Canadian Standards Association (CSA), zicebisa ukusetshenziswa kwezimpawu zokuphuma ezibomvu ezizikhanyisayo ukuze kube nokubonakala okungcono, ikakhulukazi ezindaweni lapho kungase kube nokuphazamiseka kukagesi. Izindinganiso zase-Australia, ezichazwe yi-Standards Australia, zigcizelela ukufakwa kwezimpawu zokuphuma ezihambisana ne-AS 2293, ehlanganisa nezincazelo zensayo, ukukhanya, nokubekwa. Zombili lezi zizwe zikhuthaza ukusetshenziswa kwezimpawu zokuphuma ze-LED ngenxa yokuhlala kwazo isikhathi eside nokusebenza kahle kwamandla. Ukuqonda lezi zihluke kubalulekile kumafemu amakhulu emhlabeni jikelele kanye nabakhi bamazwe ngamazwe ukuze kuqinisekiswe ukuhambisana kokuphepha okuqhubekayo phakathi kwemingcele.

Ukufakwa kahle kwezimpawu zokuphuma kubalulekile njengokwakhiwa kwazo kanye nobuchwepheshe bazo. Inqubo ibandakanya ukufakwa ngendlela ehlelekile ukuze kuqinisekiswe ukuthi zonke izindlela zokuphuma zikhonjiswa, kuqinisekiswe ukuthi izimpawu zibonakala kusukela kuyo yonke indawo ngaphakathi kwesakhiwo. Izinto ezifana nokuphakama kokufakwa, ibanga phakathi kwezimpawu, kanye nokuhlanganiswa nezinhlelo zokukhanyisa eziphuthumayo kumele kuhambisane nezindinganiso ezifanele. Isibonelo, izimpawu kumele zifakwe phezulu kweminyango noma ezindaweni ezingenazo izithiyo ezivela kumafenisha noma emiklamo. Ukusebenzisa ubuchwepheshe obuphambili obufana nezimpawu zokuphuma ze-LED noma izixazululo ze-seexel zokuphuma ezivela kubahlinzeki abathembekile njenge-AnshineTech kungathuthukisa ukuqinisekiswa nokusebenza kahle kwamandla. Ukuqinisekisa ukugcinwa njalo nokuhlolwa kwezimpawu zokuphuma kuqinisekisa ukuthi zihlala zisebenza lapho kudingeka kakhulu.

Izimpawu zokuphuma ziyizici ezibalulekile zokuphepha ezisindisa izimpilo ngokuhola abantu ngaphandle kwezimo eziyingozi. Ukuhlonipha izindinganiso ezibekiwe zeziphumo, ukufaka ubuchwepheshe bokukhanyisa besimanje obufana nezimpawu zokuphuma ze-LED, nokwazi umehluko phakathi kwezizwe nezamazwe omhlaba kubalulekile ukuze kuqinisekiswe ukulungela ezimweni eziphuthumayo. Izinhlangano ezifana ne-AnshineTech zinikeza imikhiqizo yesimanje, kuhlanganise nezimpawu zokuphuma ezibomvu ezizikhanyisayo, ezihlangabezana nezidingo eziqinile zokuphepha ngenkathi zinikeza ukuqina nokulula kokufakwa. Ekugcineni, ukuzinikela ekuhambeni nezinguquko eziqhubekayo ezimpawini zokuphuma kuqinisekisa ukuthi izakhiwo zihlala zindawo zokuphepha, ezikwazi ukuvikela abantu ngesikhathi sezimo eziphuthumayo.
