Umuburo
Gukemura ibibazo: Iki gikoresho kirashobora kwangirika bitewe no gusohora amashanyarazi (ESD).
Ibidukikije bihagaze neza birasabwa cyane.Kurikiza umurongo ngenderwaho ukurikije uburyo bukwiye bwa ESD.
Umutekano wa Laser: Imirasire itangwa nibikoresho bya laser birashobora guteza akaga mumaso yabantu.Irinde guhura n'amaso kumirasire itaziguye cyangwa itaziguye.
