Ukuqonda Amazinga Okuphepha Endwangu: Umhlahlandlela Wezindwangu Zekilasi A, B, kanye ne-C

Emakethe yanamuhla yabathengi, ukuphepha kwezindwangu kubaluleke kakhulu, ikakhulukazi emikhiqizweni ethintana ngqo nesikhumba. Izindwangu zihlukaniswa ngamaleveli amathathu okuphepha: Ikilasi A, Ikilasi B, kanye Nekilasi C, ngayinye enezici ezihlukile nokusetshenziswa okunconyiwe.

**Izindwangu Zekilasi A** zimelela izinga eliphakeme kakhulu lokuphepha futhi ziklanyelwe ngokuyinhloko imikhiqizo yezingane. Lezi zihlanganisa izinto ezifana namanabukeni, izingubo zangaphansi, amabhishi, izingubo zokulala, nezinto zokulala. Izindwangu ze-Class A kufanele zihambisane nemithetho eqinile, enokuqukethwe kwe-formaldehyde okungeqile ku-20 mg/kg. Azinawo odayi be-amine abanuka i-carcinogenic nezinsimbi ezisindayo, okuqinisekisa ukucasuka okuncane kwesikhumba. Ukwengeza, lezi zindwangu zigcina izinga le-pH eduze nokungathathi hlangothi futhi zibonisa ukushesha kombala okuphezulu, okuzenza ziphephe esikhumbeni esibucayi.

**Izindwangu Zekilasi B** zifanele ukugqokwa kwabantu abadala nsuku zonke, okuhlanganisa amahembe, izikibha, iziketi, namabhulukwe. Lezi zindwangu zinezinga lokuphepha elimaphakathi, elinokuqukethwe kwe-formaldehyde okufakwe ku-75 mg/kg. Nakuba ingenawo ama-carcinogens aziwayo, i-pH yawo ingase iphambuke kancane ekungathathi hlangothi. Izindwangu ze-Class B ziklanyelwe ukuhlangabezana nezindinganiso ezijwayelekile zokuphepha, zinikeza ukushesha okuhle kombala nokunethezeka kokusetshenziswa kwansuku zonke.

**Izindwangu zeClass C**, ngakolunye uhlangothi, zenzelwe imikhiqizo engathinti ngokuqondile isikhumba, njengamajazi namakhethini. Lezi zindwangu zinesici sokuphepha esiphansi, namazinga e-formaldehyde ahlangabezana nezindinganiso eziyisisekelo. Nakuba zingaqukatha amanani amancane ezinto zamakhemikhali, zihlala ngaphakathi kwemingcele yokuphepha. I-pH yezindwangu ze-Class C ingase futhi iphambuke ekungathathi hlangothi, kodwa akulindelekile ukuthi yenze umonakalo omkhulu. Ukushesha kombala kuyisilinganiso, futhi okunye ukufiphala kungenzeka ngokuhamba kwesikhathi.

Ukuqonda lawa mazinga okuphepha kwendwangu kubalulekile kubathengi, ikakhulukazi lapho bekhetha imikhiqizo yezingane noma lezo ezinesikhumba esibucayi. Ngokwaziswa, abathengi bangenza izinqumo eziphephile ezibeka kuqala impilo nokuphila kahle.
