Hantida Alaabta iyo Deganaanshaha:
1.Urka Ethanol oo kale ah.Ku qallalan biyo, ethanol, ether, chloroform.Waxay dhalaali karaan alkaloids, caag iyo walxaha kale ee organic iyo qaar ka mid ah walxaha aan organic ahayn.Heerkulka qolka, wuu shidi karaa wuuna gubi karaa, uumigiisuna way fududahay in la sameeyo isku-dhafka walxaha qarxa marka lagu daro hawo.
2.Alaabtu waa sun yar, hawlwadeenku waa inuu xidhaa qalabka ilaalinta.Khamriga isopropyl waa sahlan tahay in la soo saaro peroxide, mararka qaarkood waxay u baahan yihiin in la ogaado ka hor isticmaalka.Habka ayaa ah: qaado 0.5mL khamriga isopropyl, ku dar 1ml 10% potassium iodide xal iyo 0.5mL 1:5 milmi hydrochloric acid iyo dhawr dhibcood oo istaarij ah, rux 1 daqiiqo, haddii buluug ama buluug-madow oo la caddeeyey inuu leeyahay peroxide.
3.Dool iyo sun yar.Sunta uumiga ayaa laba jeer ka badan yahay ethanol, suntuna waa ka soo horjeedaa marka gudaha la qaato.Uumiga sare wuxuu leeyahay suuxdin cad, xanaaq indhaha iyo xuubka mareenka neefsashada, waxay dhaawici kartaa retina iyo neerfaha indhaha.Afka LD505.47g/kg ee jiirka, xoogga la oggol yahay ugu badnaan hawada 980mg/m3, hawl-wadeenadu waa inay xidhaan maaskaro gaas ah.Xiro indho-shareer gaas-ku dheggan marka xooga la saaro.Qalabka iyo dhuumaha xidha;hirgelin hawo-qaadasho maxalli ah ama mid dhammaystiran.
4.Wax yar sun ah.Saamaynta jireed iyo ethanol ayaa la mid ah, sunta, suuxdinta iyo kicinta xuubka xabka ee mareenka sare ee neef-mareenka ayaa ka xoog badan ethanol, laakiin maaha mid xooggan sida propanol.Ku dhawaad ma jiraan wax ururin ah oo jidhka ah, iyo awoodda bakteeriyada ayaa 2 jeer ka xoog badan tan ethanol.Heerarka ugu sarreeya ee 1.1mg/m3.Xaddiga ugu badan ee la oggol yahay ee goobta shaqada waa 1020mg/m3.
5. Xasilooni: Xasilooni
6.Waxyaabaha mamnuuca ah: Walaxyada oksida ee xooggan, acids, anhydrides, halogens.
7.Hazard of polymerisation: Non-polymerisation
