Uyini umehluko phakathi kwengozi nokungavumelekile enkundleni yegalofu?
Emidlalweni yegalofu, izindawo ezingavunyelwe zifanekiselwa ngezigxobo ezimhlophe ezibonisa umngcele wendawo. Izingozi zimakwe ngezigxobo ezibomvu ezibonisa indawo enesijeziso ngaphakathi kwendawo yenkundla (isib. amanzi, amaxhaphozi).  Lapho ibhola lishaywa ngaphandle komkhawulo, umdlali wegalofu ujeziswa ngesibhamu esisodwa futhi kudingeka ashaye ibhola futhi endaweni efanayo. Lapho ibhola lishayeka endaweni eyingozi, umdlali wegalofu naye ujeziswa ngesibhamu esisodwa, kodwa unenketho yokushaya isibhamu esilandelayo endaweni efanayo noma endaweni lapho ibhola lawela khona umngcele oyingozi.
