Mirayiridzo yebhegi reweti yekushandisa: 1. Chiremba anosarudza bhegi reweti rine zvinodiwa zvinoenderana nemamiriro ezvinhu emurwere; 2. Mushure mekubvisa pakeji, tanga wabvisa chivharo chekudzivirira chiri pachubhu yekudonhedza mvura, batanidza chinobatanidza chekunze checatheter nepakeji yechubhu yekudonhedza mvura, uye gadzirisa tambo yekukwira, tambo kana tambo iri pamusoro pebhegi rekudonhedza mvura, woishandisa; 3. Tarisa huwandu hwemvura mubhegi uye chinja bhegi reweti kana drain nenguva. Kuchenesa: Nzira yekuuraya utachiona: Kuchenesa ethylene oxide gas. Nguva yekushanda kwekuchenesa: Makore maviri kubva pazuva rekuchenesa kana ganda rava kurongedza zvakanaka. Kuchenjerera: 1. Chigadzirwa ichi chinofanira kushandiswa nachiremba akadzidziswa nehunyanzvi; 2. Sarudza maitiro akakodzera uye zvinodiwa; 3. Mirayiridzo yekurapa yechipatara nebhuku remirayiridzo yechigadzirwa zvinofanirwa kucherechedzwa pakushandisa. Yambiro: 1. Chigadzirwa ichi chinoshandiswa kamwe chete uye hachifanirwe kushandiswazve; 2. Pakeji yacho yakakuvara, ndapota usashandise; 3. Nyatsocherechedza zuva rekupera kwehutachiona pabhegi rekurongedza, uye hazvibvumirwi kushandisa kupfuura nguva yakatarwa; 4. Usarasa chigadzirwa ichi mushure mekushandisa, uye chibate zvinoenderana nemitemo yenyika yekurasa marara ekurapa. Zvinodiwa zvekuchengetedza: Chigadzirwa ichi chinofanira kuchengetwa muimba yakachena ine hunyoro husingapfuuri 80%, isina gasi rinoparadza, mhepo inofema zvakanaka, yakaoma uye inotonhorera, kudzivirira kubuda kwechinhu.
