Iimpawu kunye nezinto eziluncedo:
1. Ukusetyenziswa kwamandla aphantsi kunye nokusebenza kakuhle kwemveliso.
2. Inkcitho encinci yezinto ezikrwada, akukho lungcoliseko lothuli, kunye nezinga eliphantsi lokusilela.
3. Kwaye ngenxa yesakhiwo se-silos yezinto eziluhlaza, umgca wokuvelisa uthatha indawo ye-1/3 yomgca wokuvelisa flat.
