| Iikhowudi zoMngcipheko | I-R23/24/25 – Ityhefu ngokuphefumla, xa udibana nesikhumba naxa uginyiwe. I-R34 – Ibangela ukutsha I-R43 – Inokubangela uvakalelo ngokudibana nolusu |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S27 – Khulula ngoko nangoko zonke iimpahla ezosulelekileyo. S36/37/39 – Nxiba iimpahla ezikhuselayo ezifanelekileyo, iiglavu kunye nokhuseleko lwamehlo/ubuso. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) |
