Ubukhulu, izinga lokushisa lokuqala, izinto zokusebenza kanye nokuma kuzoshintsha izikhathi zokupheka, futhi ukunikela akukwazi ukwahlulelwa ngesisindo sodwa. Sicela uhlele isikhathi sakho ngokulandela izindlela zokupheka ezinokwethenjelwa futhi uqinisekise izinga lokushisa langaphakathi nge-thermometer yokudla. Ukusikeka okuphelele kwenyama yenkomo, ingulube newundlu kudinga ukuphumula okungenani imizuzu emi-3 ngemva kokufinyelela ku-145°F; isixhumanisi somthombo sobubanzi obugcwele.
