Ibisobanuro by'ibicuruzwa
Imiyoboro yacu yo kurinda umuriro ikorwa hakoreshejwe inzira yitonze ikomeza yunamye imirongo myiza yicyuma muburyo bwimiterere hanyuma ugasunika ubushishozi bukabije. Iyi miyoboro yo gukora udushya itanga imiyoboro mire miremire, ikomeza idakomeye kandi iraramba gusa, ariko nayo yizewe cyane kubisabwa. Niba ukeneye gutwara amazi, imyuka cyangwa ibikoresho bikomeye, imiyoboro yacu yagenewe yitonze kwihanganira ingaruka zibidukikije bikaze, kubungabunga umutekano n'imikorere.
Usibye imikorere yabo yibanze ya fluid no kwimura ibintu, imiyoboro yacu isutse kandi nibyiza kubisabwa. Guhinduranya kwabo bituma hahitamo ubwitonzi bwo hejuru kumishinga yo kubaka, sisitemu yo kurinda umutekano yumuriro, nibindi bikorwa remezo bikenewe.
Ku bijyanye n'umutekano, kwiringirwa kwacuUmurongo wumurironi igisubizo cyizewe. Twumva akamaro ko kubaka sisitemu yizewe, cyane cyane ahantu hashobora kubaho. Niyo mpamvu dushyira imbere ubuziranenge no kwizerwa mubicuruzwa byose dukora.
Inyungu y'ibicuruzwa
1. Ubwa mbere, iramba ryabo rituma bashobora kwihanganira ibihe bikabije, kuguha amahoro yo mumutima mubihe bikomeye.
2. Igishushanyo mbonera cyongera imbaraga zumuyoboro, ryemerera uburyo bunoze no kugabanya ibyago byo kumeneka. Ibi ni ngombwa cyane cyane mubikorwa byumutekano wambaye umuriro aho buri mwanya wa kabiri.
3. Twiyemeje ubuziranenge busobanura imiyoboro yo kurinda umuriro ihura n'ibipimo ngenderwaho by'inganda, butuma bubahiriza no kwizerwa. Muguhitamo ibicuruzwa byacu, ntabwo ushora imari gusa, ahubwo ushora ike, ahubwo urimo kubisubizo biteza imbere imikorere yimikorere.
Ibicuruzwa Kubura
1. Ingaruka zikomeye nigiciro cyambere cyo kwishyiriraho, gishobora kuba hejuru kuruta ibindi bikoresho.
2. Inzira yo gusudira, mugihe ituma iramba, irashobora kumenyekanisha intege nke niba idakozwe neza.
3. Kubungabunga rusange birakenewe kandi gukumira ruswa no kwemeza kuramba, bishobora kongera amafaranga yo gukora muri rusange.
Ibibazo
Q1. Ni ibihe bikoresho ukoresha kuri imiyoboro yo kurinda umuriro?
Amateka yumuriro avanwa mubyuma ahejuru, agenga imbaraga kandi yizewe muburyo butandukanye.
Q2. Nabwirwa n'iki ko imiyoboro yawe yo kurinda umuriro ikwiranye nibyo nkeneye?
Dutanga ubunini butandukanye. Ikipe yacu irashobora kugufasha gusuzuma ibyo ukeneye no gusaba igisubizo cyiza.
Q3. Ni ubuhe buryo bw'umutekano ibicuruzwa byawe byubahiriza?
Ibikoresho byacu byo kurinda umuriro byujuje ubuziranenge bwumutekano, buremeza ubwikorezi bwizewe bwibikoresho bishobora guteza akaga.
Q4. Imiyoboro yo kurinda umuriro irashobora kwihatirwa?
Nibyo, dutanga uburyo bwihariye bwo kuzuza ibisabwa byihariye byumushinga harimo ingano, ubunini no guhinga.
Q5. Ni ubuhe buryo bwo kuyobora bwo gutumiza?
Ibihe byo gutanga biratandukanye bitewe nubunini nibisobanuro, ariko turaharanira gutanga bidatinze tutabangamiye.
