Invisible Guardian: Uburyo abakora ibikoresho by'umutekano mu by'imiti barinda aho bakorera
Udusanduku tw’uburinzi bw’imiti rusange—ubwoko ukoresha mu gukurura ibikoresho by’inganda—dukunze gufatwa nk’aho “duhagije.” Dusa neza, dufite ibyapa byo kuburira, kandi dushyira akamenyetso mu gasanduku ku rutonde rw’amategeko yubahirizwa. Ariko mu kazi nyako, akenshi tunanirwa aho tugomba kuba dufite akamaro: umutekano nyawo.
Muri laboratwari imwe ya chimie ya kaminuza, hari akabati kakozwe ku bwinshi kabikaga aside sulfure nyinshi. Igihe ako gasanduku kamenekaga, nta kintu na kimwe cyashoboraga gufunga. Aside yamenetse, yangiza andi makontena, ikata hasi muri sima, bituma laboratwari ifunga amasaha abiri. Ku bw'amahirwe, nta muntu wakomeretse—ariko ubutumwa bwari busobanutse neza. Iyo kabati ntiyari igisubizo cy'umutekano. Yari ububiko gusa bufite agapapuro ko kuburira. Ntikari gafite ibisobanuro birambuye bibuza impanuka kuba ibiza: kugenzura neza ibyuka bimeneka, guhumeka neza kw'imyotsi yangiza, no gutandukanya imiti idahuye n'iyo.
Udusanduku tw’uburinzi bw’imiti ni ingenzi mu bintu bitandukanye, harimo inganda zibika imiti ihumanya ikirere mu nganda, laboratwari z’ubushakashatsi za kaminuza zicunga ibintu bidafite ingano, ibyumba by’ubumenyi by’amashuri birimo ethanol, na laboratwari z’ibitaro zicunga ibikoresho byangiza ibidukikije. Buri hantu hari uburyo bwa buri munsi, uburyo imiti ivangwa, n’amabwiriza yo kuyitunganya. Ibi bintu ntibishobora kwemerwa n’akabati kamwe gusa, gakunze guhatira abakozi kunyuranya n’akabati aho kugakuramo inyungu.
Abakora utubati tw’umutekano w’ibinyabutabire dukora ibirenze gukora udukingirizo tw’ibyuma gusa. Nyuma yo gukora ubushakashatsi ku myitwarire y’abantu, imbogamizi z’umwanya, n’ibinyabutabire, bakora utubati duhuza neza n’ibikorwa bya buri munsi. Aba bakora utu tubati si abatanga gusa abashinzwe umutekano n’abayobozi b’ibigo; ni abanyamuryango mu kugabanya ibyago, bafasha mu guhindura amategeko agenga umutekano mu buryo bunoze mu gihe habaye ikibazo.
Ingaruka zihishe z'umutekano w'amakabati y'ingano imwe akwiranye n'abantu bose
Utubati dusanzwe dukunda kwangirika mu buryo bumwe na bumwe—kandi ibyo byangiritse bigaragara neza ni byo byari ingenzi cyane mu mutekano.
Ikibazo cya mbere ni umwanya. Akabati gasanzwe k’umutekano gafite ubugari bwa metero enye gashobora kugaragara neza ku mpapuro, ariko mu nganda nyazo akenshi ntigakwira hafi y’umurongo w’umusaruro. Iyo bibaye, abakozi bategekwa kugenda intera ndende—rimwe na rimwe barenga metero 15—batwaye ibikoresho biremereye byo gushongesha. Uko igihe kigenda gihita, ibyo bitera umunaniro, inzira z’ubusamo, n’igishuko gikomeye cyo gusiga imiti mu ijoro rimwe gusa “iri rimwe gusa.” Uburyo bworoshye butangira kurenga umutekano.
Ikibazo cya kabiri ni uburyo utu tubati dukoresha imiti itandukanye. Imiterere myinshi isanzwe ikoresha igice kimwe gifunguye, bivuze ko ibintu bishobora gushya, ibintu byangiza, ibisigazwa, n'ibintu bishongesha byose bihurira ahantu hamwe. Ku kirango, ibyo bishobora kugaragara nk'ububiko bukurikije amategeko, ariko mu by'ukuri ni ibintu biteje akaga. Gutonyanga gato kagombaga kuba nta kibazo bishobora kuba ikibazo cy'inkongi y'umuriro cyangwa bigatera ingaruka mbi ku mikorere ya shimi.
Ikosa rya gatatu ni igishushanyo mbonera cyirengagiza abantu bakoresha akabati. Muri laboratwari zo mu mashuri yisumbuye, utubati ture turerire dukunze guhatira abanyeshuri kuzamuka ku ntebe kugira ngo bagere ku miti y'ibanze. Ongeraho imfunzo zibura cyangwa zakozwe nabi zirinda abana, kandi ibyago birushaho kwiyongera - cyane cyane iyo abanyeshuri bato cyangwa abashyitsi bahari.
Izi si udukosa duto mu miterere yazo. Ni icyuho gihungabanya umutekano buri munsi, bigatuma ububiko busanzwe buhinduka ikibazo gihoraho.
Ni iki gituma akabati k'umutekano w'ibinyabutabire gasanzwe "gateguye aho gukorera"?
Ishingiro ry'utubati tw’umutekano twa shimi twakozwe ku giti cyawe ni igitekerezo cyoroshye cy'uko umutekano utagomba kuguhatira guhindura uburyo ukora. Abakora ibintu bakomeye batangira batega amatwi gahunda z'ikipe yawe, aho utuye, n'imiti yawe mbere yo gushushanya utubati dutanga uburinzi tudateye isoni. Ibintu bidashoboka kubitandukanya ni ibi bikurikira:
1. Ibikoresho bihuye n'imiti yawe:
Nubwo icyuma gisa n'aho gikomeye, imiti myinshi ntitekereza kimwe. Ibintu bikomeye byangiza nka hydrochloric cyangwa aside sulfurike bishobora kwangiza icyuma gisanzwe buhoro buhoro, rimwe na rimwe mu mezi make. Igitangira ari uko ubuso bwangiritse gato buhinduka amazi, ahantu hadakomeye, n'utubati tutameze neza.
Abakora utubati tw’umutekano bashobora gufasha muri iki gihe. Bahitamo ibikoresho hakurikijwe imiti yihariye ifatiwe aho gukoresha icyuma kimwe kuri buri kintu cyose. Imiti yo gusukura yavuyemo amazi n’ibintu byoroshye byangiza ni byiza cyane ku byuma bya galvanised. Ibyuma bita galvanious bya 316-grade bitanga ubudahangarwa bukomeye kuri aside zikomeye nka aside nitrique muri laboratwari. Byongeye kandi, utubati twa polypropylene ni bwo buryo bwizewe bwo gukoresha imiti nka aside hydrofluoric yangiza icyuma burundu.
Mu guhuza ibikoresho by'akabati n'ubutabire bw'imbere, ingese irakurwaho cyane. Mu ma laboratwari menshi, utubati tw'icyuma gikozwe mu buryo bwa "stainless steel" duhora tudafite ingese mu gihe cy'imyaka itanu cyangwa irenga, mu gihe utubati tw'icyuma gisanzwe akenshi tuba tugomba gusimburwa nyuma y'umwaka umwe cyangwa ibiri gusa. Ntabwo ari ukuramba gusa—ni ukurinda kwangirika mbere yuko bibaho.
2. Imiterere y'Akabati Gakomeye Ituma Umutekano Ugaragara mu Byumba Biciriritse:
Imihanda mito yo muri laboratwari, utubati tw’ibimera duto cyane, utuzu duto two mu nzu dukikije aho bakorera, n’ibyumba by’ishuri bifite umwanya muto wo ku nkuta ni bimwe mu ngero zitandukanye z’imiterere y’aho bakorera. Abakora ibikoresho by’ikoranabuhanga bakora ibipimo nyabyo: utubati two mu mfuruka dukoresha uduce duto tudashobora kugeramo; utubati duto twa santimetero 24 tw’ubugari dukwiranye n’utundi duce duto two muri laboratwari, kandi utundi duce dushobora gukururwa inshuro enye tudakoresheje umwanya wo hasi wo kongera. Utubati tw’ikoranabuhanga dukwiranye n’aho hantu nk’uko twakozwe (kuko ari ko bimeze), bityo laboratwari ifite umwanya wa metero 3 hagati y’udupfundikizo tw’umuriro ntikenera kongera gushyira ibikoresho byayo. Ibinyabutabire bibikwa hafi y’aho byagenewe gukoreshwa bitewe n’iyi miterere igabanya umwanya, igabanya gutwara n’ingaruka mbi.
3. Gushyira hamwe ibice kugira ngo habeho uburinganire hagati y’ibinyabutabire n’ibinyabutabire;
Bishobora kuba bibi kubika imiti idahuye hamwe kuko ogisijeni n'ibinyabutabire bishobora gufatwa n'umuriro, kandi ibintu bitwika n'ibinyabutabire bishobora kugira ingaruka mbi. Amatsinda ategetswe kurenga ku mategeko y'umutekano kugira ngo ahuze imiti yabo yose kuko utubati dusanzwe dufite igice kimwe kinini gusa. Ibice bibiri cyangwa bitatu bifite inzugi zitandukanye n'udusanduku two gusukura ni byo abakora ibikoresho byihariye bakemura ibi. OSHA isaba ibikoresho bifunga umuriro ku bice bishya, ibice birwanya imiti ku bice bishya, n'inzugi zifunze ku binyabutabire kugira ngo birinde kuvanga umwuka. Kubyubahiriza ntibikiri akazi kuko abakozi bashobora kugera kuri buri bwoko mu mutekano badakoresheje ibikoresho bidakwiye.
4. Gukurikiza amategeko byihariye:
Amabwiriza agenga umutekano w’ibinyabutabire (OSHA muri Leta Zunze Ubumwe za Amerika, WHMIS muri Kanada) arakomeye, kandi utubati dusanzwe dukunze gufata igabanywa ry’amafaranga kugira ngo tuzigame amafaranga. Ingero zirimo utubati dufunga umuriro tubura ku bikoresho bishya, utubati dusesa amazi twuzuza munsi ya 10% by’akabati, cyangwa ibirango bidasobanutse neza. Iyubahirizwa ry’amategeko rishyirwa muri buri gice n’inganda zikora ibikoresho byihariye: inzugi zifunga zigashyirwaho na OSHA n’utubati dusesa umuriro, utubati dusesa amazi ingano y’akabati, n’ibirango bya “Corrosives” cyangwa “Flammables”. Mu gutanga inyandiko z’iyemezabuguzi ku igenzura, bahindura igenzura ry’amategeko kuva ku nzira zigoye bakabishyira ku masezerano yihuse. Igenzura rya OSHA rya laboratwari yakoreshaga utubati twihariye ryamaze iminota icumi; abagenzuzi babonye ibice byanditseho, bagenzura icyemezo, maze bakomeza.
Ibyiza byo gukorana n'uruganda rukora ibikoresho by'umutekano mu by'imiti
Kurema ibidukikije birangwa n'umutekano kandi by'ubwenge ni ugukorana n'uwakoze utubati tw'uburinzi bw'imiti, atari ugushaka gusa aho kubika imiti. Nubwo utubati dusanzwe dushobora "gufata" imiti yawe mu buryo bw'ikigereranyo, akenshi ntabwo dukora neza mu bikorwa bifatika. Ku rundi ruhande, utubati tw'uburinzi twakozwe kugira ngo duhuze neza n'agace kawe, dufate imiti ijyanye n'ibyo ukeneye, kandi tworohereze imirimo ya buri munsi mu buryo bwizewe kandi bworoshye.
Zifite ibintu byatekerejweho neza nk'udusanduku tw'amazi twashyizwemo, sisitemu zo guhumeka zoroshye guhuzwa n'uburyo bwo gukora muri laboratwari yawe, hamwe n'ibice bitandukanye by'imiti idahuye.
Kubera ko utubati tugizwe n'ibikoresho bishobora gucunga imiti yawe by'ukuri, haboneka impanuka nke, gusukura vuba, n'utubati tumara igihe kirekire. Umutekano uba ingirakamaro, wizewe, kandi ushingiye ku itsinda rifite igisubizo cyihariye.
Umwanzuro: Umutekano Mwiza Ukwiye Akabati Gakomeye
Ibice bya kera by’akabati, nk’amabati yangiritse cyangwa yangiritse, bibikwa n’amatsinda menshi y’umutekano nk’imfashanyigisho. Bigaragariza abashya uburyo imiterere rusange isenyuka byoroshye: ibice bimwe bitera ibiza, ibyuma byangiritse, n’amasafuriya yatakaye. Mu buryo bunyuranye, amabati yihariye aba ikintu cy’ingenzi mu mikorere ya buri munsi: ibice byanditseho amazina byorohereza kugenzura vuba ububiko; ibikoresho bizunguruka bigendana n’imirongo y’umusaruro, kandi ibikoresho bito bikwira muri laboratwari zikomeye. Bikunze gukoreshwa kuko bihuye n’uburyo ubucuruzi bukora, bityo ntibicaye mu mfuruka gusa.
Byongeye kandi, buri kabati ryiza cyane rifite umukora ufitanye isano nawe ku mutekano w'abakozi bawe. Bitera icyizere aho gutera amasanduku y'icyuma gusa. Gira icyizere ko kabati ritazasenyuka, ko rizakurikiza amabwiriza, kandi ko itsinda ryawe rizayikoresha kuko ijyanye n'ibyo bakeneye. Aho gukorera hatekanye hashingiye kuri ubwo bwizere.
