Igishushanyo cya siyansi kizana imiterere yumvikana, yoroshye kandi itanga ubuntu mubice mugihe imiyoboro myiza yurukiramende ikoreshwa kumurongo ikozwe neza kandi igateranyirizwa hamwe kugirango izane umutekano nigihe kirekire. Inzira yimodoka ijyanye nihame rya ergonomique hamwe ninsinga zikwirakwizwa mubyuma bya tekinike bizana urwego rwo hejuru rwihumure n'umutekano.
Igitambaro kirinda neza abakoresha ibyapa biremereye kandi bikarushaho kongera umutekano mukoresha.Ibikoresho byohejuru-byanyuma bikoreshwa kumihuza bizana kugenda neza.Impapuro zateguwe neza hamwe nintambwe ndende zo guhumuriza byorohereza abakoresha kwihata hanyuma bakazana kugenda neza.
