Ijazi lokuhlinza elilahlayo lidlala indima emibili yokuzivikela ngesikhathi sokuhlinzwa. Okokuqala, ingubo yokuhlinza isungula isithiyo phakathi kwesiguli nabasebenzi bezokwelapha, sinciphise amathuba okuba abasebenzi bezokwelapha bathinte igazi lesiguli noma nolunye uketshezi lomzimba neminye imithombo yokutheleleka ngesikhathi sokuhlinzwa; okwesibili, ingubo yokuhlinza ingavimba amakoloni / ukunamathela esikhunjeni sabasebenzi bezokwelapha noma ezingutsheni Amagciwane ahlukahlukene ebusweni adluliselwa ezigulini ezihlinzekwayo, ngokugwema ngempumelelo ukutheleleka kwamagciwane amelana nemithi eminingi njenge-methicillin-resistant Staphylococcus aureus (MRSA) ne-vancomycin-ukumelana ne-enterococci (VRE).

Ingubo yokuhlinza elahlwayo yenziwa ngezindwangu ezingezona ezilukiwe ze-SMS, ezisebenzisa ngokugcwele izinzuzo zezindwangu ezingalukiwe nezindwangu ezingezona ezelukiwe: isilinganiso, ukumelana kwe-Mildew ne-acid kanye ne-alkali ukumelana; izinga eliphakeme lokucindezela kwamanzi nokuphefumula.

Izingubo zokuhlanza ezilahlayo zisetshenziselwa ukuhlinzwa nokwelashwa kweziguli; ukuhlolwa kobhubhane ezindaweni zomphakathi; ukubulala amagciwane ezindaweni ezinegciwane; futhi futhi isetshenziswe kabanzi kwezempi, ezokwelapha, amakhemikhali, ukuvikelwa kwemvelo, ezokuhamba, ukuvikela ubhubhane neminye imikhakha.
