Amazinga Nezinhlelo Zokuqinisekisa Ubufakazi Bokuqhuma

Emikhakheni eyahlukene efana nowoyela, izitshalo zamakhemikhali, izimayini, ukuphepha komlilo okuphuthumayo, ezemithi, kanye nokucubungula ukudla, izindawo ezisengozini yokuqhuma zivamile ngesikhathi sokukhiqiza, ukucubungula, isitoreji, kanye nelogistics. Ukuqinisekisa ukuphepha komuntu siqu kanye nokukhiqiza, imikhiqizo kagesi esetshenziswa kulezi zindawo idinga isitifiketi sokuvikela ukuqhuma.

Chaza

Siyini ngempela isitifiketi semikhiqizo kagesi engaqhumi? Kubhekiselwa ekugunyazweni kwezinto zikagesi ezisetshenziswa ezimbonini ezifana nowoyela, izitshalo zamakhemikhali, izimayini zamalahle, izindwangu ezikhanyayo, nokucubungula okusanhlamvu, lapho eziqhumayo amagesi, uthuli, noma imicu ingase inqwabelane.

Isifunda ngasinye emhlabeni wonke sinamazinga nezinhlelo ezihlukene zokuqinisekisa imikhiqizo kagesi engaqhumi. Ake sihlole ezinye zalezi zinhlelo zokunikeza izitifiketi zomhlaba wonke.

IECEx

Uhlelo lwe-IECEx, ikhuthazwe yi-International Electrotechnical Commission (I-IEC), ihlose ukuqeda umehluko emishinini nasezinsizeni ezisetshenziswa endaweni eneziqhumane emhlabeni jikelele, ukukhuthaza ukuhwebelana kwamazwe ngamazwe ngesikhathi siqinisekisa ukuphepha. Izinga lamanje lithi I-IEC 60079.

Isitifiketi se-IECEx sesiphenduke indlela ekhethwayo yokugunyazwa kokuphepha kwamazwe ngamazwe emikhiqizweni esezindaweni eziyingozi futhi yaziwa emazweni amaningi., kuhlanganise ne-Australia, E-New Zealand, Brazil, Canada, China, Japan, INingizimu Korea, I-Malaysia, Singapore, Iningizimu Afrika, kanye ne-United States.

Izitifiketi ezikhishwe yi-IECEx zilayishwa ngokuzenzakalelayo kuwebhusayithi yabo, lapho abakhiqizi nabasebenzisi bokugcina bengathola khona imibhalo efanele.

I-ATEX

Uhlelo lwe-ATEX, eyamukelwa yi-European Commission, ihlose ukwakha imakethe ebumbene phakathi kwe-Europe, ukususa imigoqo yobuchwepheshe ekuhwebeni kanye nokuqinisekisa ukuhamba ngokukhululeka kwemishini ezindaweni ezingaba neziqhumane phakathi kwamazwe angamalungu. Lo myalelo ubandakanya kokubili okokusebenza kwezimayini nezingezona ezezimayini, inweba incazelo yezindawo ezingase zibe neziqhumane ukuze zifake uthuli, ezivuthayo amagesi, umhwamuko, nezinkungu emoyeni, futhi ibeka izidingo eziyisisekelo zempilo nokuphepha kanye nezinqubo zokuhlola ukuhambisana kwemishini ehloselwe lezo zindawo. Umyalelo wamanje uthi I-ATEX 100A.

CNEX

Uhlelo lwesitifiketi saseChina lwe-CNEX, yenganyelwe yiNational Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation (I-CQST), isekelwe kumazinga kazwelonke afana ne GB3836 uchungechunge. Kubandakanya ukuhlolwa nokuqinisekiswa kokusebenza okuvikela ukuqhuma kwemikhiqizo eminingi, kuhlanganise izinjini, izinto zikagesi, ukukhanya, izinsimbi, izinsiza zokuxhumana, izimoto, kanye nemishini yemishini njengamakheshi nama-cranes, ekhipha izitifiketi ezingaqhumi ngokufanele.

I-North America

ENyakatho Melika, uhlelo lokuphepha oluvame kakhulu lusekelwe ku-National Electrical Code (I-NEC), nge I-UL913 kanye ne-TIA4950 okuyizindinganiso eziyinhloko zokuvikela ukuqhuma.

Canada

Isistimu yaseCanada, iqondiswa yi-Canadian Standards Association (I-CSA), inhlangano enkulu yezwe yokuqinisekisa ukuphepha kanye nomthuthukisi wamazinga ohamba phambili kanye nendikimba yezitifiketi zekhwalithi, okwamanje yamukela i I-CSA 60079 standard for isitifiketi sokuvikela ukuqhuma.
