1. Muuqashada: budo bunni khafiif ah&dare madow madow.Aan sun ahayn, aan ur lahayn, aan guban oo aan qudhun lahayn baararka birta ah.
2. Caagaga cajiibka ah: Sida xaalad isku dhafan oo ah halka cadadka sibidhka iyo burburitaanku ay hore u go'an yihiin, isku darka biyaha waxaa lagu yarayn karaa 18-28% marka lagu daro shubka la xoojiyay 0.5-1.0%.Tirakoob ahaan, xoogga cadaadiska maalinta 1aad, maalinta 3aad iyo maalinta 28aad ka dib hal codsi waxaa kordhay 60-90% iyo 25-60% siday u kala horreeyaan marka lagu daro qiyaasta isku dhafka caadiga ah. Natiijadu waxay tahay, xoogga cadaadiska, xoogga xajinta ,xoogga balaadhinta iyo moduleska barti waa la wanaajin doonaa ilaa xad.
3. Hagaajinta khaladka isku-dhafka shubka leh ee biyaha iyo burburka sidoo kale. Sida xaalad isku mid ah, burburka waa la kordhin karaa 5-8 jeer marka lagu daro 0.75% qiyaasta isku-dhafka ah.
4. 15-20% sibidhka waxa lagu kaydin karaa marka wakiilka lagu daro 0.75% qiyaasta isku-dhafka ah, taas oo shuruud u ah isku-dhafka iyo xoogga isku midka ah.
