Impahla ekhuselayo, enje ngeengubo zokugquma okanye iifaskoti, zinokuwukhusela umzimba kwiziphazamiso ezinokubakho okanye ukuchitheka.
Ukongeza kwiPPE, kubalulekile ukulandela iindlela zokuphatha ezifanelekileyo xa usebenza ngoqhagamshelo lwe-NPT. Oku kubandakanya ukusebenzisa izixhobo ezichanekileyo zomsebenzi kunye nokusebenzisa isixa esifanelekileyo setorque ngexesha lofakelo. Ukuqiniswa ngokugqithiseleyo kungonakalisa imisonto, ngelixa ukuqiniswa ngaphantsi kunokukhokelela ekuvuzeni. Kubalulekile ukwenza ulungelelwaniso oluchanekileyo ukuqinisekisa uqhagamshelo olukhuselekileyo nolungenavuza.
Ukuhlolwa rhoqo kunye nokugcinwa kubalulekile ukuchonga naziphi na iingozi ezinokuthi zibe kho zokhuseleko ezinxulumene noqhagamshelo lwe-NPT. Oku kuquka ukujonga iimpawu zokuvuza, ukubola, okanye umonakalo kwimisonto. Nayiphi na imiba kufuneka iqwalaselwe ngokukhawuleza ukuthintela ukuwohloka okungakumbi nokuqinisekisa ukhuseleko oluqhubekayo nokuthembeka kwenkqubo.
Ukuqukumbela, uqhagamshelo lwe-NPT lusetyenziswa ngokubanzi kumashishini ahlukeneyo kunye neenkqubo zokudityaniswa kwazo ezikhuselekileyo nezingavuziyo. Banikezela ngeenzuzo ezifana nokuhambelana nezixhobo ezahlukeneyo zemibhobho, ukuchasana noxinzelelo oluphezulu kunye neemeko zokushisa, kunye neendleko-ukusebenza. Ukufakela okufanelekileyo kunye nokugcinwa kubalulekile ekufezekiseni uqhagamshelo oluthembekileyo, kwaye iingcebiso zokusombulula ingxaki zinokunceda ukulungisa imiba eqhelekileyo.
