Byongeye kandi, pinholes hamwe n’ibyangiritse byangiza bya plastiki bishobora kuvamo ubushuhe bwo kwinjira mumigozi ya kabili, ibiranga amashanyarazi birangirika. Yagaragaje kandi ko kwangirika kw'ikoti ya kabili atari ngombwa ko ahantu hashobora kwangirika kwangirika, ibyo bikaba bitanga umurongo wa kabili no gukemura ibibazo byinshi, bityo rero mugikorwa cyo gukora umugozi, mubisanzwe uburyo butatu bwo kwirinda ubushyuhe kandi butarinda amazi. umugozi wuzuye cyangwa wuzuyemo peteroli ukoresheje ibikoresho birenze urugero, ibyo hamwe na jele ya peteroli murugo hamwe nibisanzwe. Amashanyarazi ya peteroli yuzuye insinga, umugozi wa fibre optique icyuho cyose, hagati yikidodo kitagira amazi kigira uruhare rwa fibre optique iva mubidukikije, ikongerera ubuzima, kandi nta kubungabunga bishobora gukomeza umutekano muremure kandi wizewe wo kwanduza fibre optique.
