Ukusingathwa njalo kuvela emsebenzini wanoma yiliphi ibhizinisi lezimboni. Ahlukile ngohlobo lwawo nezinga lobungozi. Kubaluleke kakhulu ukuzihlunga, kanye nokuphatha kahle isigaba ngasinye semfucuza. Ochwepheshe bahlukanisa imfucumfucu ngokuya ngamthelela muni nokuthi unamaphi amanqanaba engozi kwimvelo yemvelo.
Ukunqunywa kwesigaba sengozi
Zonke izinhlobo zemfucuza kanye nesigaba sazo sobungozi zibhalwe ku-Federal Classification Catalog. Isigaba se-hazard sinqunywa ngezindlela ezilandelayo:
- ngesikhathi sokuhlolwa, kucutshungulwa umphumela wohlobo oluthile lwemfucuza ezitshalweni noma ezilwaneni;
- indaba ifundwa ngokuqondisisa, kwenziwa ukuhlaziywa kobuthi, futhi isiphetho silungiswa ngokuya ngemiphumela ebaliwe;
- ukuzimisela kwengozi kwenziwa ngokusebenzisa indlela yokumodela yekhompyutha.
Sekukonke kunamaqembu amane emfucuza ayingozi emvelweni, kepha uma egcinwe ngokungafanele futhi elahlwa ngokungafanele, noma iyiphi imfucuza iyingozi emvelweni.
Isigaba esingu-1 sengozi
Lesi sigaba sifaka izinto eziyingozi kakhulu ezidala ukulimala okukhulu empilweni yomuntu nasemvelweni yemvelo. Lokhu kufaka phakathi izinhlobo ezilandelayo zemfucumfucu:
- amakhemikhali izinto;
- amalambu we-fluorescent;
- zonke izinto eziqukethe i-mercury.
Lapho ulahla udoti wesigaba esingu-1 esiyingozi, kuyadingeka ukuthi ulandele ngokuqinile yonke imithetho. Iphutha elilodwa lingaholela enhlekeleleni yemvelo nasekulahlekelweni yimpilo. Ngaphambi kokusebenzisa lezi zinto, kufanele zenziwe zingenabungozi, ngemuva kwalokho zingcwatshwe. Ngeshwa, udoti manje usulahlwa ngaphandle ngokungalawuleki, ngakho-ke, izinto eziningi eziqukethe i-mercury zivame ukulethwa ezindaweni zokulahla umhlaba, okudala ukulimala okukhulu emvelweni.
2 ikilasi lobungozi
Imfucuza kulesi sigaba nayo idala umonakalo omkhulu emvelweni nasempilweni yabantu. Ngemuva kokukhishelwa kwalezi zinto emvelweni, ibhalansi ye-eco ijwayelekile kuphela ngemuva kweminyaka engama-30. Lesi sigaba sifaka imfucuza elandelayo:
- amabhethri angavuseleleka;
- ama-acid ahlukahlukene;
- udoti ovela embonini kawoyela.
Isigaba sama-hazard esingu-3
Leli qembu lifaka imfucuza enobungozi ngokulingene. Ngemuva komonakalo odalwe yimfucuza enjalo, isimo semvelo sizobuyiselwa kungakapheli iminyaka eyishumi. Lokhu kufaka izinto ezilandelayo:
- abalalayo abamithiswe ngamakhemikhali;
amafutha omshini wokulahla;
- izinsalela zikapende namavanishi.
Isigaba se-4 sengozi
Leli qembu liqukethe imfucuza enezinga eliphansi lobungozi. Banomthelela omncane ongemuhle emvelweni, futhi ukululama kwenzeka ngaphakathi kweminyaka emithathu. Uhlu lwale mfucumfucu lubandakanya izinto ezilandelayo:
- udoti wokhuni okhulelwe ngamakhemikhali;
- amathayi ezimoto namathayi;
- isihlabathi esingcoliswe yimikhiqizo kawoyela;
- udoti ngemuva kokwakhiwa;
- iphepha elisele nekhadibhodi;
- okusanhlamvu okuncane okuchotshoziwe kwetshe elichotshoziwe;
- amalahle angcolile.
Ngokuqondene nemfucuza yeklasi lesi-5, empeleni ayisiyo ingozi emvelweni.
Izici zikadoti wesigaba 4
Uma kubhekwa ngokuningiliziwe imfucumfucu yesigaba se-4 sengozi, kufanele kuqashelwe ukuthi izinga labo lobungozi linqunywa ukugxila kwezinto eziyingozi endaweni yokugcina le doti. Ukuhlushwa okuvumelekile kungu-10 mg ngemitha ngayinye yesikwele. imitha. Izinga elibulalayo lingu-50,000 mg / sq. Izinto ezinjalo zithinta umbuthano onobubanzi bamamitha angama-54. Ingozi enkulu emvelweni nasempilweni yomuntu idalwa yizinto ezingcoliswe ngamafutha. Zonke izinkampani eziphatha imfucuza kufanele zikhethe izindlela zazo zokulahla ngokwemikhakha yobungozi bencithakalo.
