(1) Ukumelana nomswakama ophezulu kwindawo emanzi, itshokolethi kunye neemveliso zayo phezu kweswekile ayiyi kuchithwa, i-icing okanye i-anti-frost phenomenon, ngoko ke, ukupakishwa kunokumelana nomswakama ophezulu.
(2) Itshokolethi ephezulu yokumelana neoksijini kunye neemveliso zayo kunye nokunxibelelana kwexesha elide kunye neoksijini, ekulula ukuyicoca amacandelo amanqatha, okukhokelela ekunyukeni kwexabiso leperoxide yetshokolethi kunye neemveliso zayo.Ke ngoko, ukupakishwa kunokumelana okuphezulu ne-oxygen.
(3) Ukutywinwa kakuhle ukuba ukutywinwa kwepakethi kukubi, umphunga wamanzi kunye neoksijini evela ngaphandle uya kungena kwipakethe, echaphazela inzwa kunye nomgangatho wetshokolethi kunye nemveliso yayo.Ke ngoko, ukupakishwa kunokutywinwa kakuhle.
