1. Ububanzi bomnatha weflethi awuyi kuba ngaphantsi kwe-3m, ubude bungabi ngaphezu kwe-6m, nokuphakama komnatha othe nkqi akuyi kuba ngaphantsi kwe
2. UMesh usekwe ngokweemfuno zokusetyenziswa, kwaye owona nqanaba lingaphantsi kwe-10cm. Izixhobo ezinjengeVinylon, nylon, nylon, njl. Njl. Kufuneka isetyenziswe. I-Nets eyonakeleyo okanye ekhuthazayo yokhuseleko kunye neminatha yePolypropylene inqatshelwe ngokungqongqo.
3. Iukhuseleko lwethakufuneka ihambelane neplanethi ethe tyaba okanye ephezulu ngaphandle kwaye iphantsi ngaphakathi, ngokubanzi 15º.
4. Ukuphakama komthwalo womnatha akudluli kwi-6m (kubandakanya i-6m). Ngenxa yemfuno yokwakha, kuvunyelwe ukuba igqithe i-6m, kodwa ibukhulu ayiyi kudlula i-10m, kunye namanyathelo okhuseleko afana nokongezwa.
Xa ukuphakama komthwalo kungaphantsi kwe-5m (kubandakanya i-5m), inethi ikhulisa ngaphandle kwesakhiwo (okanye eyona ndawo isebenzayo) ubuncinci i-2.5m. Xa ukuphakama komthwalo kungaphezulu kwe-5m ukuya kwi-10m, kufanele ukuba yandise ubuncinci i-3m.
I-5. Umnatha wokhuseleko awufanelanga ukuba uqine ngexesha lokufakwa. Emva kokufaka umnatha ngobubanzi be-3m ne-4m, ububanzi bendlela ethe tye yi-2.5m kunye ne-3.5m ngokwahlukeneyo.
6. Owona mgangathweni uphakamileyo phakathi kwenqwelomoya kunye nomphetho wenqwelomoya oxhasayo umqhubi akazukudlula i-10cm. Isithuba esiphakathi kwe-slassing yomnatha wokhuseleko akufuneki ibe ngaphezulu kwe-4m.
7. Emva kotyando kwindawo ekhuselweyo iyayeka, inokuchithwa.
8. Ukudiliza kufuneka kwenziwe phantsi kweliso elisondeleyo labasebenzi abanamava.
9. Umnatha wokhuseleko kufuneka ususwe ukusuka phezulu kuye ezantsi. Kwangelo xesha, amanye amanyathelo okuthintela ukuwa nokusothuka ngokomzimba kufuneka kuthathwe ngokweemeko zeziza, njengokunxibe iibhanti zokhuseleko kunye nezigcina-ntloko zoKhuseleko.
