d.Umoya ozungezile ngokusobala awungcoliswa uthuli, intuthu, igesi ebolayo noma evuthayo, isitimu noma isifutho sikasawoti;
e.Ubukhulu be-icing akufanele budlule i-20mm;
f.Isivinini somoya asidluli ku-34m/s;
g.I-fissure yokuzamazama komhlaba ayidluli ama-degree angu-8;
h.Izimo zokuswakama:
Isilinganiso senani lomswakamo olinganiselwe okalwe phakathi kwamahora angama-24, ongadluli ku-95%;
Isilinganiso senani lokucindezela komhwamuko okalwa phakathi kwama-24h aweqi ku-2.2kPa;
Umswakama ojwayelekile wanyanga zonke aweqi ama-90%;
Isilinganiso sanyanga zonke sokucindezela komhwamuko wamanzi aweqi ku-1.8kPa;
Uma izimo zokusetshenziswa ezijwayelekile ezibalwe ngenhla zeqiwa, sicela uthintane nomkhiqizi kusengaphambili, futhi sicela ucacise lapho u-oda;
Izimo zokusebenzisa okungajwayelekile
Kubandakanya indawo yokusetshenziswa ngokweqile efana nokuphakama okungaphezu kwamamitha ayi-1000, ukushintsha kwezinga lokushisa okusheshayo, uqweqwe olungaphezulu kuka-20mm, ukungcola okukhulu, ukujiya okukhulu, isikhutha, isihlabathi, uthuli, amakhaza amakhulu, ukushisa okushisayo, ukudlidliza, umthelela, ukushwibeka, njll., sicela uxoxisane kusengaphambili uma uyala.
