Mu kunywa kwa misi yose, mu kunywa icayi co mu biro, no mu gushaza mu nzu, ibikombe vy’ibirahuri ni vyo abaguzi bahitamwo cane kubera ko bitekanye, bigaragara, kandi bikoroha gusukura. Ibikombe vy’ibirahuri vy’inzira zine, bike, bigororotse-, n’imiterere yavyo yihariye n’ibiranga, biratandukanye n’ibikombe vy’ibirahuri vy’uruzitiro vya kera kandi birakundwa n’abaguzi bashima ubwiza bukeyi n’ubumenyi bw’abakoresha. Aha hepfo, turabamenyesha ivyiza nyamukuru vy’ibikombe vy’ibirahuri vy’imirongo ine, bike, bigororotse-.
Ubwa mbere, nuhitemwo ikintu gifise umutekano kandi gica ibibatsi. Ivyuma vy’ibirahuri vy’agaciro kanini, vy’agaciro gatoyi, bigororotse-bifise impande z’ibirahuri vy’agaciro kanini vy’ibirahuri vy’agaciro kanini, vy’ukuri-bikoreshwa mu bushuhe bwinshi. Ivyo bintu birasukuye, ntibigira ubuhumane, amabuye y’agaciro, amabuye y’agaciro yitwa cadmium be n’ivyuma bikomeye bishobora gutera ingorane, ivyo bikaba bituma ata bintu bishobora gutera ingorane biva aho biva. Yaba guteka amazi ashushe, icayi gitoyi, icayi c’ivyamwa, canke gufata ibinyobwa birimwo aside nk’amazi y’urubura n’umutobe, ntibizogira ico bikoze ku kinyobwa, bizotuma uwubikoresha agira umutekano wo kunywa kandi bikaba bibereye gukoreshwa igihe kirekire-ku musi ku musi. Muri ico gihe nyene, ibirahuri vy’iborosilicate vy’agaciro kanini birafise ububonero bwinshi cane, kandi bifatanijwe n’umubumbe w’uruhome rworoshe-, ububonero burarushiriza kugaragara, bugaragaza neza ibara n’ibice vy’ikinyobwa kiri imbere. Kubera ko vyoroshe kandi biruhura, biratuma umuntu anywa neza kandi akagira n’ubwiza.
Ica kabiri, iyo nkuru ndende kandi y’inzira y’inzira y’inzira, iratorera umuti ingorane z’ibikombe vy’ibirahuri vya kera bikaba ari bimwe kandi bikaba ari vyinshi. Igishushanyo c’inzira y’inzira ni co kintu gihambaye cane muri iki gikombe c’ibirahuri, gifise imirongo isukuye n’imfuruka zisongoye, kigaheba ubuzinguzingu bw’ibirahuri vy’uruzitiro kandi kigatanga umubumbe mutoyi kandi uteye igomwe uhuye neza n’imigenzo itandukanye. Igishushanyo c’uruhome rworoshe-, naho nyene kigaragaza ko ibikoresho bikomeye, kigabanya uburemere bw’uruhome rw’igikombe, bikaba bituma umuntu yumva ko afise uburemere buke kandi akaryoherwa no gufata. Yaba iyo gukoresha mu rugo ku musi ku musi, iyo gutwara mu biro, canke iyo uri mu rugendo, ntizotera umuzigo, iringaniza ubwiza n’uburyohe. Ikindi kandi, umubiri w’inzira y’inzira utuma vyoroha guteranya no kubika, bikaba bizigama umwanya wo ku biro no ku kubika, bikaba bituma canecane bibereye abakodesha, abakozi bo mu biro be n’ibintu bisaba kubika vyinshi.
Ica kabiri, iyo nzira igororotse-irakora, irabereye gukoresha, kandi yoroshe gusukura, bituma gusukura no gucungera buri musi biba umuyaga. Igishushanyo c’uruhande kigororotse-gihuye n’ivyo umuntu akeneye buri musi, gifise uruhande ruryoshe kandi ruzunguruka rudashobora gukaraba iminwa yawe, bigatuma ushobora gusuka no kunywa neza. Hagati aho, uruhome rw’imbere rw’igikombe gifise uruhande rugororotse-nta mfuruka zikomeye-kugira ngo -zishikeko, ivyo bikaba bituma kiryoha kandi kidakomeye, kandi ntirushobora gusiga amabara y’icayi, amabara y’amazi canke amasigarira y’ibinyobwa. Igihe cose umuntu amaze kuyikoresha, arashobora kuyisukura gusa mu kuyihanagura n’amazi canke mu kuyihanagura n’igitambaro gipfutse, ivyo bikaba bidasaba ibindi bikoresho vyo kuyisukura, ivyo bikaba bituma umuntu azigama umwanya n’inkomezi.
Ubwa nyuma, akamaro gahambaye kuruta ayandi kari mu mahitamwo menshi y’ubushobozi bwayo, ipfuka ibintu vyinshi kandi igashitsa ivyipfuzo bitandukanye vy’ikoreshwa. Ikirahuri c’inzira y’inzira, gitoya, kigororotse-kifise ubunini butandukanye, kuva ku kigereranyo c’ibiro gikomeye c’imililitiro 200, kibereye amamesa y’ibiro n’ameza yo iruhande y’igitanda kugira ngo umuntu anywe ku musi ku musi no guteka utukombe dutoduto tw’icayi; ku bigereranyo vy’ubunini buringaniye-bw’imililitiro 300-400, bibereye gukoreshwa mu rugo no mu biro, bihuye n’ivyo kunywa ku musi ku musi no gutegura icayi c’ivyamwa; kandi ku bigereranyo vy’ubushobozi bunini-birenga 500ml, bibereye amakoraniro y’umuryango n’ingendo zo hanze, bihuye n’ivyo abantu benshi bakeneye canke inzoga nyinshi. Abakoresha barashobora guhitamwo bivanye n’ibintu bitandukanye be n’ibisabwa vyo gukoresha. Ikindi kandi, iyo kirahuri ntibereye gusa ku muntu ku musi ku musi, ariko kandi irakoreshwa nk’ikintu co kwerekana no gukoresha mu maduka y’icayi n’ikawa. Igishushanyo caco coroshe kiragaragaza ibara ry’ibinyobwa, kigatuma umuntu abona ko gifise agaciro kanini kandi kigatuma gishobora gukoreshwa mu vy’ubudandaji.
