I. Kev phom sij

Txoj kev ntxeem tau: Inhalation, ingestion, percutaneous absorption.

Kev phom sij rau kev noj qab haus huv: Zoo ib yam li aniline, tab sis tsis muaj zog dua li aniline, tuaj yeem ua rau mob ntawm daim tawv nqaij. Kev nqus tau ua rau tsim cov methemoglobin thiab cyanosis. Kev xeev siab, kiv taub hau, mob taub hau thiab ntshav tuaj yeem tshwm sim tom qab kev sib cuag.

Toxicological cov ntaub ntawv thiab ib puag ncig tus cwj pwm

Mob toxicity: LD501410mg/kg (rat qhov ncauj); 1770mg / kg (luv percutaneous)

COV KHOOM ZOO TSHAJ PLAWS: Nyob rau hauv cov ntaub ntawv ntawm cov nplaim taws, kub kub los yog kev sib cuag nrog oxidizing tus neeg sawv cev, muaj kev pheej hmoo ntawm hlawv thiab tawg. Toxic nitrogen oxide fumes raug tso tawm los ntawm tshav kub decomposition.

Combustion (decomposition) khoom: carbon monoxide, carbon dioxide, nitrogen oxides.

Pov tseg txoj kev kho

Txhaum teb

Tshem cov neeg ua haujlwm tawm ntawm thaj chaw muaj kab mob mus rau thaj chaw nyab xeeb, txwv tsis pub cov neeg ua haujlwm tsis sib xws nkag mus rau thaj chaw muaj kab mob, thiab txiav tawm qhov hluav taws kub. Nws raug pom zoo tias cov neeg teb xov xwm xwm txheej ceev hnav lub tshuab ua pa ntawm tus kheej (SCBA) thiab cov khaub ncaws tiv thaiv tshuaj. Tsis txhob tuaj rau hauv kev sib cuag ncaj qha nrog cov nchuav, thiab ntsaws cov xau thaum ua kom muaj kev nyab xeeb. Cov tshuaj tsuag dej yuav txo tau evaporation, tab sis yuav tsis txo qhov flammability ntawm cov nchuav hauv qhov chaw kaw. Ncua nrog sib tov ntawm xuab zeb los yog lwm yam nonflammable sorbent thiab sau rau pov tseg ntawm qhov chaw pov tseg. Yog tias muaj cov dej nchuav loj loj, cov khoom siv berms yog siv, tom qab ntawd los ntawm kev sau, hloov, rov ua dua, lossis pov tseg yam tsis muaj kev kho mob.

Txoj kev pov tseg pov tseg: incineration, incinerator nrog afterburning chamber, nitrogen oxides los ntawm incinerator los ntawm cov scrubber tshem tawm.

Kev tiv thaiv

Kev tiv thaiv ua pa: Hnav lub npog ntsej muag roj thaum muaj kev pheej hmoo ntawm cov vapors. Hnav ib lub tshuab ua pa rau tus kheej (SCBA) thaum muaj xwm txheej ceev los yog khiav tawm.

Kev tiv thaiv qhov muag: Hnav cov tsom iav kev nyab xeeb tshuaj.

Cov khaub ncaws tiv thaiv: Hnav lub tes tsho nruj thiab cov khau looj roj hmab ntev.

Kev tiv thaiv tes: Hnav hnab looj tes roj hmab.

Lwm tus: Kev haus luam yeeb, noj mov thiab haus dej haus cawv raug txwv nruj ntawm qhov chaw ua haujlwm. Hloov thiab ntxuav khaub ncaws ua haujlwm tam sim ntawd. Tsis txhob haus cawv ua ntej lossis tom qab ua haujlwm, thiab siv dej sov so rau da dej. Saib xyuas cov co toxins. Ua haujlwm ua ntej thiab kuaj mob raws sijhawm.

Kev Pabcuam Ua Ntej

Kev sib cuag ntawm daim tawv nqaij: Tshem cov khaub ncaws uas tsis huv tam sim ntawd thiab yaug kom huv si nrog xab npum thiab dej. Ua tib zoo mloog tes, taw thiab rau tes.

Kev Tiv Thaiv Qhov Muag: Tam sim ntawd rub daim tawv muag thiab yaug nrog dej txaus los yog dej ntsev.

Inhalation: sai sai tshem tawm ntawm qhov chaw mus rau huab cua ntshiab. Muab cov pa oxygen yog tias muaj teeb meem ua pa tshwm sim. Yog hais tias ua pa nres, resuscitate tam sim ntawd. Nrhiav kev kho mob.

Noj: gargle, haus dej, lavage plab thiab ces muab lub qhov ncauj activated charcoal induce raws plab nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj. Nrhiav kev kho mob.

Txoj kev tua hluav taws: pos huab dej, ua npuas ncauj, carbon dioxide, hmoov qhuav, xuab zeb.

Ntau txoj kev kho

Nws yog tau los ntawm cov tshuaj tiv thaiv ntawm aniline thiab methanol nyob rau hauv lub xub ntiag ntawm sulfuric acid ntawm qhov kub thiab txias. Kev siv cov khoom siv raw: aniline 790kg / t, methanol 625kg / t, sulfuric acid 85kg / t. Cov tshuaj tiv thaiv ntawm aniline thiab trimethyl phosphate tuaj yeem npaj tau hauv chav kuaj.

Muaj nuj nqi thiab siv kho kom raug

Nws yog cov khoom siv tseem ceeb ntawm cov tshuaj tua kab mob thiab tshuaj tua kab mob "Mefenamic acid", thiab tseem tuaj yeem siv los ua cov khoom nruab nrab ntawm cov tshuaj dyestuff, tshuaj tua kab thiab lwm yam khoom siv tshuaj.

Solubility: Insoluble hauv dej, soluble hauv cov kua qaub, ethanol, ether, chloroform, carbon tetrachloride, benzene.

Kev Siv Tseem Ceeb: Siv los ua qhov nruab nrab ntawm cov dyestuff, siv hauv kev tsim cov vanillin, azo dyestuff, triphenylmethane dyestuff, kuj tuaj yeem siv los ua hnyav, stabilizer, analytical reagent, thiab lwm yam.

Daim ntawv thov: Feem ntau yog 10% kev daws teeb meem ntawm styrene, hu ua # 2 accelerant. Feem ntau siv ua ke nrog 2 # curing agent (dibenzoyl peroxide). Nws yog ib qho kev kho zoo heev uas cov resin muaj ntau cov phenol dawb los yog qhov twg polyester molecular saw muaj ib tug loj molecular branched qauv. (xws li vinyl ester resin curing, bisphenol A hom polyester resin curing, chlorinated choj anhydride hom polyester cob, thiab lwm yam.)
