• Isakhiwo esilula kanye nokuhlukahluka okuqinile

• Isiqu sevalvu esinokwelashwa kokuqina kwendawo

• Ukwamukela uxhumano olungenaphinikhodi

• Isiqu esingavumeli ukushaywa umoya

• Hlukanisa umzimba kanye nesiqu ngesilinganiso esiphakathi

• Ukufakwa okulula endaweni

• Ukususa i-sulphurization kanye nokususa i-nitration, ukuphrinta nokudaya amanzi amdaka
• Amanzi ompompi
• indle kamasipala
• Izimboni
• Ukukhiqizwa kwempuphu eyomile kanye nokuthuthwa kwayo
• Uhlelo lokulethwa kwepayipi likawoyela lokupholisa olushintsha ugesi oluphezulu kakhulu

Isiqu sihlukanisiwe ne-medium

Isiqu nediski kuxhunywe ngaphandle kwephini, ngemva kokuhlanganiswa, kuba yinto ebalulekile. Lesi sakhiwo siqinisekisa ukuthi isiqu asixhumani nomshini.

Isiqu esingavimbeli ukushaywa umoya

Ingxenye engezansi ye-flange kanye nesiqu icutshungulwa ngomsele, umsele wesiqu usethwe ngomsele we-“U” bese ufaka indandatho ye-O ukulungisa umsele we-circle.

I-NSEN ilandela ngokuqinile ukulungiswa kwamahhala, ukushintshwa kwamahhala kanye nezinsizakalo zokubuyiselwa kwamahhala zingakapheli izinyanga eziyi-18 ngemuva kokuthi ivalvu isisebenzile noma izinyanga eziyi-12 ngemuva kokufakwa nokusetshenziswa epayipini ngemuva kokusebenza kwangaphambilini (okuzofika kuqala). 

Uma kwenzeka ivalvu yehluleka ngenxa yenkinga yekhwalithi ngesikhathi sokusetshenziswa epayipini ngaphakathi kwesikhathi sewaranti yekhwalithi, i-NSEN izohlinzeka ngensizakalo yewaranti yekhwalithi yamahhala. Insizakalo ngeke iphele kuze kube yilapho ukwehluleka sekulungisiwe futhi ivalvu ivame ukusebenza futhi iklayenti lisayina incwadi yokuqinisekisa.

Ngemva kokuphela kwesikhathi esishiwo, i-NSEN iqinisekisa ukuhlinzeka abasebenzisi ngezinsizakalo zobuchwepheshe ezisezingeni eliphezulu ngesikhathi noma nini lapho umkhiqizo udinga ukulungiswa nokunakekelwa.
