Waa la rakibi karaa iyada oo aan la damin korontada.
U adkaysta wareegyada heerkulka sare iyo hoose, taasoo keentay anti-gabowga iyo cimri dherer.
Dhexroorka khafiifka ah iyo dhexroorka yari waxa ay yareeyaan culayska ay keenaan barafka iyo dabayshu, iyo sidoo kale culayska saaran munaaradaha iyo dabaylaha.
Dhererka baaxadda weyn iyo taagga ugu dheer ayaa ka badan 1000m.
Waxqabadka wanaagsan ee xoogga xajinta iyo heerkulka.
Tirada badan ee xargaha fiber-ka, miisaanka fudud, ayaa lagu dhejin karaa khadka korantada, kaydinta ilaha.
Qaado walxo aramid ah oo xoog badan si ay ugu adkeysato xiisad xoogan oo uga hortagto laalaabyada iyo daloolada
Cimrigu naqshadeynta waa in ka badan 30 sano.

Xadhkaha OYI waxay ku duuduuban yihiin bakelite, alwaax, ama durbaanno alwaax bir ah. Inta lagu jiro gaadiidka, qalabka saxda ah waa in la isticmaalo si looga fogaado waxyeellaynta xirmada iyo in si fudud loogu maareeyo. Fiilooyinka waa in laga ilaaliyaa qoyaanka, laga ilaaliyaa heerkulka sare iyo dhimbilaha dabka, laga ilaaliyo foorarsiga xad dhaafka ah iyo burburinta, lagana ilaaliyo cidhiidhiga farsamada iyo dhaawaca. Looma ogola in uu haysto laba dherer oo xadhig ah hal durbaan, labada darafna waa in la xidhaa. Labada daraf waa in lagu xidhaa gudaha durbaanka, oo dhererka kaydka ee xadhig aan ka yarayn 3 mitir waa in la bixiyaa.
Midabka calaamadaynta fiilada waa caddaan. Daabacaadda waa in lagu fuliyaa 1 mitir galka dibadda ee fiilada. Halyeyga calaamadaynta galka dibadda waa la bedeli karaa iyadoo loo eegayo codsiyada isticmaalaha.
Warbixinta imtixaanka iyo shahaado bixinta waa la bixiyay.
Yeroo baay’ee adda addaa adda baasuun barbaachisaadha jedhan OYI. Nala soo xidhiidh hadda si aan u aragno sida aan kuugu caawin karno inaad ku xirnaato oo aad ganacsigaaga u qaaddo heerka xiga.
