Ukupakishwa kweemveliso zobisi kufuneka kube neepropati zomqobo, ezifana nokuchasana kwe-oksijini, ukuchasana nokukhanya, ukunyanzeliswa komswakama, ukugcinwa kwevumba, ukuthintela ivumba, njl ... Qinisekisa ukuba iibhaktheriya zangaphandle, uthuli, iigesi, ukukhanya, amanzi kunye nezinye izinto zangaphandle azikwazi ukungena kwingxowa yokupakisha , kwaye kwakhona uqinisekise ukuba amanzi, ioli, amacandelo amnandi, njl. eziqulethwe kwiimveliso zobisi azingeni ngaphandle; Kwangaxeshanye, ukupakishwa kufuneka kube nokuzinza, kwaye ukupakishwa ngokwawo akufuneki kube nevumba, amacandelo akufuneki abole okanye afuduke, kwaye kufuneka akwazi ukumelana neemfuno zobushushu obuphezulu kunye nokugcinwa kobushushu obuphantsi, kwaye ugcine uzinzo phantsi komgangatho ophezulu. kunye neemeko zokushisa eziphantsi ngaphandle kokuchaphazela iipropati zeemveliso zobisi.
