I-6. I-Catalyst: Kwezinye izimo, kungahle kube yi-Catalyst yokuphendula okuthile kwamakhemikhali.
Kuyancibilika e-ethanol, ether, e-benzene, infeluble emanzini.
Kugcinwe endaweni eyomile, enomthunzi, enomoya opholile. 1. Ukushisa: gcina endaweni epholile neyomile kude ekushiseni nasekushisweni kwelanga okuqondile. Ngokufanelekile, kufanele igcinwe emazingeni okushisa asekamelweni.
2. Isitsha: Sebenzisa iziqukathi ze-airtight ezenziwe ngezinto ezihambisanayo (njengengilazi noma amapulasitiki athile) ukuvikela ukungcoliswa nokuhwamuka.
3. Ukuphefumula umoya: qiniseka ukuthi indawo yokugcina inomoya omuhle ukugwema ukunqwabelana kwe-vapor.
4. Ukwahlukana: Gwema kude nezinto ezingahambelani ezifana nama-oxidants aqinile nezisekelo eziqinile.
I-5. Ilebula: Faka ilebula ngokucacile iziqukathi ngegama lamakhemikhali, imininingwane yengozi, nosuku lokuthola.
I-6. Izindlela zokuphepha: Bheka yonke imihlahlandlela efanele yokuphepha kanye nemigomo yokuphatha nokugcina amakhemikhali.
Izeluleko ezijwayelekile
Bheka udokotela. Khombisa le ncwadi yezobuchwepheshe yezokuphepha kudokotela esizeni.
Donsa
Uma u-inhalid, hambisa isiguli emoyeni omusha. Uma uyeka ukuphefumula, nikeza ukuphefumula kokufakelwa. Bheka udokotela.
Ukuxhumana kwesikhumba
Hlambulula ngensipho namanzi amaningi. Bheka udokotela.
Ukubonana kwamehlo
Hlambulula kahle ngamanzi amaningi okungenani imizuzu eyi-15 bese uthintana nodokotela.
Incela
Ungalokothi uyondla noma yini emlonyeni uye komunye umuntu ongazi lutho. Hlanza umlomo wakho ngamanzi. Bheka udokotela.
1. Ukulandela umthetho wokulawula: Qiniseka ukuthi uhambisana nemithetho yasekhaya, kazwelonke, neyamazwe omhlaba maqondana nokuhamba kwamakhemikhali. Lokhu kungafaka nemihlahlandlela elandelayo ebekwe izinhlangano ezinjengoMnyango Wezokuvakasha wase-US (i-DoT) noma i-International Air Transport Association (IATA).
2. Ukulebula okufanele: Faka ilebula ngokucacile isitsha sokuthumela ngegama lamakhemikhali, uphawu lwengozi, nanoma yiluphi ulwazi lokuphepha olufanele. Uma kusebenza, sebenzisa amalebula afanele engozi, njengezimpawu ezivuthayo noma ezinobuthi.
3. Ukupakisha: Sebenzisa izinto ezisebenza kahle zokufaka ezihambisana ne-Ethyl P-TOLUEESEULTE. Isitsha kufanele sivuze futhi singaphuke kalula. Kudingeka uphawu lwesibili ukuvikela ukuchitheka.
I-4. Ukulawulwa kokushisa: Uma kunesidingo, qiniseka ukuthi izimo zokuthumela zigcina izinga lokushisa elizinzile ukuvikela ukonakala noma ukusabela okungafuneki.
I-5. Imibhalo: Lokhu kufaka phakathi wonke amadokhumenti adingekayo okuthumela afana nephepha ledatha yokuphepha (SDS), Isimemezelo Sokuhambisa kanye nanoma yiziphi izimvume ezidingekayo.
6
7. Impendulo ephuthumayo: Yiba nohlelo oluphuthumayo olukhona uma kwenzeka ukuvuza noma ukuchitheka ngesikhathi sokuhamba. Lokhu kufaka ukuba nekhithi yokuchitheka kanye nemishini efanelekile yokuzivikela (i-PPE) isilungile.
8. Gwema izinto ezingahambelani
Yebo, ethyl P-tolueesulfonate iyingozi. Nawa amanye amaphuzu asemqoka mayelana nokulimala kwawo okungenzeka:
1. Ubuthi: I-Ethyl P-tolueesulfonate ingadala ukucasuka esikhunjeni, emehlweni naseqenjini lokuphefumula. Ukuvezwa isikhathi eside noma okuphindaphindwayo kungadala ingozi enkulu empilweni.
2. I-Carcinogenicicity: Yize ama-sulfonates awahlukaniswa njengama-carcinogens abantu, izifundo zezilwane zikhombisile ukuthi amanye ama-sulfonates anemiphumela engaba khona ye-carcinogenic. Ngakho-ke, kunconywa ukuqapha.
I-3. Umthelela Wezemvelo: Uma kuvuzwa ngamanani amakhulu, kungadala ukulimala kwempilo yasemanzini nasendaweni yemvelo.
I-4 Njalo sebenza endaweni enomoya omuhle futhi ulandele imihlahlandlela yezokuphepha.
I-5. Ishidi ledatha yokuphepha ezibonakalayo
