Katundu ndi Kukhazikika:
1.Kawopsedwe kakang'ono kwambiri komanso kuchira msanga kuchokera ku poizoni, kotero itha kugwiritsidwa ntchito ngati mankhwala oletsa ululu. Zokwiyitsa pakhungu ndi mucous nembanemba. Makoswe akuluakulu pakamwa LD50: 1.6mL/kg. mpweya pazipita chovomerezeka ndende ya 500 × 10-6. Opaleshoni ayenera kuvala mpweya chigoba, anapeza poizoni yomweyo kuchotsedwa powonekera, symptomatic mankhwala. Ochepera mu kloridi wa methane. Mpweyawu umapweteka kwambiri ndipo ukakoka mpweya wambiri umayambitsa kupweteka kwa m'mphuno, mutu ndi kusanza. Poizoni kosatha kumayambitsa chizungulire, kutopa, kusowa kwa njala, impaired haematopoiesis ndi kuchepa kwa maselo ofiira a magazi. Madzi a methylene chloride amachititsa dermatitis pamene akhudzana ndi khungu. Kukoka mpweya wa 90.5g/m3 mu makoswe ophedwa m'mphindi 90. The olfactory pakhomo ndende ndi 522mg/m3 ndipo pazipita chovomerezeka ndende pa ntchito ndi 1740mg/m3.
2.Kukhazikika: Kukhazikika
3.Zinthu zoletsedwa: Zitsulo za alkali, aluminiyamu
4.Makhalidwe opewera kuwonekera: Kuwala, mpweya wonyowa
5.Polymerization ngozi: Kupanda polymerization
Ntchito Yogulitsa:
1.Kuphatikiza ndi kaphatikizidwe ka organic, mankhwalawa amagwiritsidwanso ntchito kwambiri ngati filimu ya cellulose acetate, kupopera kwa cellulose triacetate, dewaxing ya petroleum, zosungunulira popanga ma aerosols ndi maantibayotiki, mavitamini, mankhwala a steroidal, komanso kuyeretsa kwachitsulo pamwamba pa lacquer ndi degreasing ndi chochotsa filimu.
2.Kugwiritsidwa ntchito mu fumigation ya tirigu ndi refrigeration ya mafiriji otsika kwambiri komanso ma air-conditioning units. Amagwiritsidwa ntchito ngati wothandizira kuwomba popanga thovu la polyether urethane komanso kuwombera thovu la polysulfone.
3.Kugwiritsidwa ntchito ngati zosungunulira, zotulutsa ndi mutagen. Amagwiritsidwa ntchito mu kafukufuku wa chibadwa cha zomera.
4.Ili ndi solvency yabwino, ndi yotsika yotentha yosungunulira yokhala ndi kawopsedwe kakang'ono komanso osawotcha pakati pa zosungunulira zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale, ndipo imakhala ndi solvency yabwino kwa ma resin ambiri, parafini ndi mafuta. Amagwiritsidwa ntchito makamaka ngati chodulira utoto, chosungunulira cha petroleum dewaxing, chotulutsa zinthu zosakhazikika, chotulutsa lanolin kuchokera ku ubweya ndi mafuta odyedwa kuchokera ku kokonati, chosungunulira cha cellulose triacetate film. Amagwiritsidwanso ntchito kwambiri popanga ulusi wa acetate, vinyl chloride fiber kupanga, kukonza ndi zozimitsa moto, refrigerants, urotropine ndi zina.
5.Kugwiritsidwa ntchito pamakampani amagetsi. Nthawi zambiri amagwiritsidwa ntchito ngati choyeretsa pochotsa mafuta.
6.Yogwiritsidwa ntchito kwambiri ngati chosungunulira chamoto chokhala ndi malo otsika kwambiri otentha. Kuphatikiza pa kutsuka zosungunulira za injini za ndege, makina olondola, ndi zina zotero, zitha kugwiritsidwanso ntchito ngati chochotsera utoto, komanso kusakanikirana ndi zosungunulira zina kuti zigwiritsidwe ntchito pakutsuka m'mafakitale osiyanasiyana.
7.Amagwiritsidwanso ntchito ngati ethyl ester fiber zosungunulira, mankhwala oletsa mano am'deralo, refrigerant ndi chozimitsira moto, ndi zina zotero, ndizodziwika bwino za kupatukana kwa chromatographic ndi kulekanitsa m'zigawo za zosungunulira wamba.
8.Kugwiritsidwa ntchito ngati zosungunulira mu utomoni ndi mafakitale apulasitiki.
Zolemba Zosungira:
1.Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi moto ndi gwero la kutentha.
3.Sungani kutentha kosapitirira 32°C ndi chinyezi chosapitirira 80%.
4.Sungani chidebe chosindikizidwa.
5.Ziyenera kusungidwa mosiyana ndi zitsulo zamchere ndi mankhwala odyedwa, ndipo zisasokonezedwe.
6.Zokhala ndi mitundu yoyenera komanso kuchuluka kwa zida zozimitsa moto.
7.Malo osungira ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zogona.
