Ibikorwa bikurikira ni kirazira kubantu babaga muri laboratoire umwaka wose.Xiao Bian yabatoranije uyumunsi ahita yohereza kubantu bose kwiga!
1. Igisasu cya firigo
Mugihe cyo gukuramo cyangwa dialyse, reagent ikoreshwa kandi igashyirwa muri firigo.Mugihe gaze kama igera kumurongo wingenzi, itwikwa numuriro wamashanyarazi mugihe compressor ya firigo itangiye.
Ku ya 6 Ukwakira 1986, firigo mu kigo cy’ubushakashatsi cy’ishuri ry’ubumenyi ry’Ubushinwa ryaturikiye;
Ku ya 15 Ukuboza 1987, firigo muri laboratoire ya Ningxia Academy y’ubumenyi bw’ubuhinzi yaturikiye;
Ku ya 20 Nyakanga 1988, firigo ya “Shasong” mu rugo rw'umwarimu muri kaminuza isanzwe ya Nanjing yaturikiye.
Mu myaka mike gusa, havuzwe ibisasu birenga 10 bya firigo.Icyateye iyi mpanuka ntabwo yari nziza ya firigo ubwayo, ahubwo ni imiti nka peteroli ether, acetone, benzene na gaze ya butane yashyizwe muri firigo.Turabizi ko ubushyuhe muri firigo buri hasi.Niba imiti yaka kandi iturika hamwe nubushyuhe buke hamwe na flash point ishyizwe muri firigo, bizahindura gaze yaka umuriro mugihe cy'ubushyuhe buke.Nubwo agacupa k'icupa kagoramye cyane, ubushyuhe buke burashobora gutuma igicupa kigabanuka, valve ya gaze irekura cyangwa nigicupa cyacupa.Gazi ihindagurika ishobora kuvangwa numwuka kugirango ikore imvange iturika kandi yuzuza firigo.Umuyagankuba w'amashanyarazi wabyaye mugihe ubushyuhe bwo kugenzura ubushyuhe (cyangwa ubundi buryo bwo kugenzura) bwakinguwe cyangwa bufunze biroroshye cyane guturika.Kubwibyo, abakoresha firigo ntibagomba kubika imiti muri firigo.
2. Suka inzoga n'umuriro ufunguye
Fungura impinduramatwara yaka itara rya alcool ukoresheje pliers, hanyuma usukemo inzoga mumatara ya alcool ukoresheje ukuboko kumwe, bishobora gutera icupa ryose rya alcool gutwika no guturika.
3. Igisasu cya azote
Koresha ibirahuri na buckle bitwikiriye centrifuge kugirango upakire icyitegererezo hanyuma ubishyire mubigega bya azote.Iyo zimaze gusohoka, imitungo y'urukuta rw'imiyoboro yarahindutse, kandi ntishobora kwihanganira umuvuduko wa gaze waguka, cyangwa igitutu ntikigaragara iyo bishyushye vuba, bigatera guturika.
Kubwibyo, abantu bambara amadarubindi bafite akarusho - “Harakabaho ibirahuri!”
Abakoresha bakora azote yuzuye bagomba kwambara amadarubindi.
Incamake
Ibyago byubuzima: Iki gicuruzwa ntigishobora gukongoka kandi gihumeka, kandi guhuza uruhu na azote yuzuye bishobora gutera ubukonje.Niba azote ikorwa no guhumeka ikabije kurenza ubushyuhe busanzwe, umuvuduko wigice cya ogisijeni mu kirere uzagabanuka, bitera asifike ya anoxic.
Ingamba zambere zubutabazi
Guhuza uruhu: Niba hari ubukonje, shaka kwivuza.
Guhumeka: vuga vuba kurubuga umwuka mwiza kandi ukomeze guhumeka neza.Niba guhumeka bigoye, tanga ogisijeni.Niba guhumeka bihagaze, kora guhumeka neza hanyuma ushake inama zubuvuzi.
Ingamba zo kurwanya umuriro
Hazard: Mugihe cy'ubushyuhe, umuvuduko w'imbere muri kontineri uziyongera, bishobora gutera gucika no guturika.
Uburyo bwo kuzimya: Iki gicuruzwa ntigishobora gukongoka, kandi ibikoresho biri mu muriro bigomba guhora bikonje n'amazi yibicu.Umwuka wa azote wuzuye urashobora kwihuta mugutera amazi muburyo bwigihu, kandi imbunda yamazi ntishobora kurasa azote yuzuye.
Kuvurwa byihutirwa
Ubuvuzi bwihutirwa: guhita wimura abakozi mukarere kanduye ahantu h’umuyaga, kubatandukanya, no kubuza kwinjira.Abashinzwe ubutabazi bagomba kwambara imyuka ihumeka neza hamwe n imyenda ikonje.Ntukore ku kumeneka neza.Kata inkomoko yamenetse bishoboka.Irinde gaze guteranira ahantu hake no guturika mugihe uhuye nubushyuhe bwumuriro.Koresha umuyaga usohora kugirango wohereze gaze yasohotse ahantu hafunguye.Ibikoresho bimeneka bigomba kuvurwa neza, gusanwa no kugenzurwa mbere yo kubikoresha.
Gukoresha no kubika
Icyitonderwa cyo gukora: ibikorwa bifunze, bitanga ibihe byiza byo guhumeka.Abakoresha bagomba guhugurwa kandi bakubahiriza byimazeyo imikorere.Birasabwa ko abashoramari bambara uturindantoki dukonje.Irinde imyuka ya gaze mu kirere cyakazi.Amashanyarazi n'ibikoresho bigomba gukoreshwa neza kugirango birinde kwangirika.Koresha ibikoresho byihutirwa byo kumeneka.
Icyitonderwa cyo kubika: Bika ahantu hakonje kandi hahumeka neza, kandi ubushyuhe ntibugomba kurenga 50 ℃.
Kurinda umuntu
Kurinda sisitemu y'ubuhumekero: nta burinzi bwihariye busabwa muri rusange.Ariko, mugihe umwuka wa ogisijeni mwuka uri mukazi uri munsi ya 19%, guhumeka ikirere, guhumeka umwuka wa ogisijeni hamwe na masike maremare agomba kwambara.
Kurinda amaso: kwambara mask yumutekano.
Kurinda intoki: kwambara uturindantoki dukonje.
Ubundi burinzi: Irinde guhumeka cyane kugirango wirinde ubukonje.
