Pachimake poyizoni: mkulu ndende yomweyo amayambitsa kuyabwa diso chapamwamba kupuma thirakiti mucosa, kupweteka kwa maso, pom'ng'amba, salivation, sneezing, zilonda zapakhosi, chifuwa, etc., kenako mutu, chizungulire, nseru, kusanza, ambiri malaise, etc .; Chilango chaukali Kodi ndi chizungulire, gait. Pamene diso zakhudzana ndi styrene madzi, zingayambitse zilonda zamoto. Zotsatira aakulu: wamba neurasthenia syndrome, kupweteka kwa mutu, kutopa, nseru, kusafuna kudya, bloating, maganizo, kuyiwala, kenaka utentha mamba chala, etc. Iwo ali wapaulendoyo pa mundawo kupuma, ndi yaitali kukhudzana amayambitsa obstructive m'mapapo mwanga matenda.

makhalidwe owopsa

nthunzi wake ndi mpweya kupanga osakaniza ndi zachiwawa. Mu nkhani ya moto, kutentha yapamwamba kapena kukhudzana ndi oxidants, pali ngozi ya moto ndi kuphulika. Pankhani ya catalysts acidic monga Lewis catalysts, Ziegler catalysts, asidi sulfuric, mankhwala enaake ferric, mankhwala enaake zotayidwa, etc., polymerization chiwawa akhoza kupangidwa, ndipo wambirimbiri kutentha anamasulidwa. nthunzi yake yolemera kuposa mpweya ndi ingafalire kwa malo ndi kutali pa malo apansi.

Yosungirako ndi zinthu zoyendera

Yosungirako ndi mayendedwe zinthu: Kusunga mu ozizira ndi youma, podutsa mpweya malo. Apatuke moto ndiponso kutentha. Kuwateteza ku dzuwa. Kusunga chidebe losindikizidwa ndi kusunga mosiyana oxidants ndi zidulo. Mvetsera chitetezo amawagwiritsa ntchito yopereka akagwira ntchito. Mopepuka kutsegula ndi kutsitsa pamene amakasiya. Thanki (thanki) ntchito kayendedwe ayenera unyolo grounding, ndi kugawa dzenje akhoza anakonza m'galimoto kuchepetsa magetsi malo amodzi kwaiye mantha ndi. chithandizo kutayikira: Rapid achoke cha anthu ndi malo zakhudzana ndi malo otetezedwa kusonkhana ndi kukaniza okhwima pa mwayi. Kudula moto gwero. Avale masks, magolovesi ndi kuchucha yolandira, ndi ntchito mchenga kapena zipangizo inert kuyamwa otsala ndi kusintha kwa malo otetezedwa. The zakhudzana madzi thupi mbidagwandwa ndi mayamwidwe wa styrene Kuwaza pamwamba madzi womangika ndi mpanda kapena ngati. Munthu poizoni ndi kunditumiza ku dera atsopano komanso otetezeka wa mlengalenga, amachotsa malaya zakhudzana, rinses khungu zakhudzana, rinses maso ndi madzi ambiri, rinses thupi lonse, ndipo rinses pakamwa. Kumwa madzi ambiri, sangathe kupangira kusanza, ndiye kuchipatala. Limbikitsani pamalo mpweya kuti imathandizira volatilization wa styrene yotsalira galimoto kutali nthunzi.

Ndipo kutayikira wolunjika

Sunthani chidebe cha moto mumlengalenga poyera mmene ndingathere. Utsi madzi ku moto chidebe ozizira mpaka mapeto a moto. Wozimitsa TV: thovu, ufa wouma, carbon dioxide, mchenga. Moto wozimitsa ndi madzi si zothandiza. Mu nkhani ya moto, firefighters ayenera ntchito pa malo oteteza
