Magaca Alaabta:Trichlorethylene
Qaab molecular:C2HCl3
Lambarka CAS:79-01-6
Qaab dhismeedka molecular ee alaabta:
Trichlorethylene (TCE) waa cad, aan midab lahayn, aan guban karin (heerkulka qolka) dareere sun ah oo deggan oo leh ur u eg chloroform (ATSDR, 2011).Wax yar bay ku milmi kartaa biyaha, waxay ku milmaysaa dufanka iyo dareerayaasha organic caadiga ah, waxayna ku karkarisaa 87°C (190F).
Marka hawada la taabto, si tartiib ah ayay u qudhuntaa oo u samaysaa fosgene, chloride hydrogen, iyo chloroacetyl chloride.Trichlorethylene marka biyaha la taabto waxay noqotaa daxal waxayna samaysaa dichloroacetic acid iyo hydrochloric acid.Waxay ku milmi kartaa methanol, diethyl ether, iyo acetone.
Trichlorethylene waxaa sidoo kale loo yaqaan trichloroethene, acetylene trichloride, 1-chloro-2,2-dichlorethylene, iyo ethylene trichloride, sidoo kale waxaa badanaa loo soo gaabiyaa TRI.Waa hydrocarbon organic koloriin ah oo kacsan oo si weyn loogu isticmaalo xaalufinta biraha iyo sida hydrofluorocarbon (HFC-134a) dhexe (ATSDR, 2013).Waxa kale oo loo isticmaalaa xabagta, qaababka rinji-xariifinta, rinjiyada, lacquers, iyo varnishes.Sannadihii 1930-aadkii, TCE waxaa loo soo bandhigay isticmaalka nadiifinta qalalan, laakiin dhaqankan ayaa inta badan la joojiyay 1950-meeyadii markii TCE lagu beddelay tetrachlorethylene (PCE).Waxa ay haysataa tiro kale oo hore oo la isticmaalo oo la isku qurxiyo, daroogooyinka, cuntooyinka, iyo sunta cayayaanka lagu dilo (US EPA, 2011).Waa wasakh deegaan oo laga helay hawada, biyaha dhulka hoostiisa, biyaha sare iyo ciidda
Trichlorethylene waxa loo isticmaalaa sida dareere ahaan, nadiifinta qalalan, nadiifinta, iyo isticmaalka xaddidan ee suuxinta qalliinka.
Hydrocarbon koloriin leh oo loo isticmaalo saabuun ama dareere ahaan biraha, saliidaha, xabagta, baaruudka iyo sida wakiilka xaalufinta gemal.Waxay keeni kartaa dermatitis xiriir cuncun, exanthema guud, Stevens-Johnson syndrome, malax ama dilaac xoog leh iyo scleroderma.
Ku milmaya dufanka, dhuka, resins, saliidaha, caag, rinji, iyo faash.Ku milmaya esters cellulose iyo ethers.Loo isticmaalo soo saarista dareeraha warshado badan.Hoos-u-dhigga, nadiifinta qalalan.Soo saarista kiimikooyinka dabiiciga ah, daawooyinka, sida chloroacetic acid.
Chemwin waxay siin kartaa noocyo badan oo kaarboon-karboon ah iyo dareerayaasha kiimikaad ee macaamiisha warshadaha.Intaa ka hor, fadlan akhri macluumaadka aasaasiga ah ee soo socda ee ku saabsan ganacsiga nala samee:
1. Amniga
Badbaadadu waa mudnaantayada koowaad.Marka laga soo tago siinta macaamiisha macluumaadka ku saabsan isticmaalka badbaadada iyo deegaanka saaxiibtinimo leh ee alaabtayada, waxaan sidoo kale go'aansanay inaan hubinno in khataraha badbaadada shaqaalaha iyo qandaraaslayaasha la dhimay ilaa ugu yaraan macquul ah oo macquul ah.Sidaa darteed, waxaan uga baahannahay macmiilka inuu hubiyo in heerarka badbaadada dejinta iyo kaydinta ku habboon ay buuxiyeen ka hor inta aan la keenin (fadlan tixraac lifaaqa HSSE ee shuruudaha iyo shuruudaha iibka ee hoose).Khubaradayada HSSE waxay ku siin karaan hagitaan heerarkan.
2. Habka gaarsiinta
Macaamiisha waxay ka dalban karaan oo ka keeni karaan alaabta chemwin, ama waxay ka heli karaan alaabta warshadeena wax soo saarka.Noocyada gaadiidka ee la heli karo waxaa ka mid ah baabuurta xamuulka qaada, tareenada ama gaadiidka casriga ah (xaalad gooni ah ayaa jira).
Marka laga hadlayo shuruudaha macmiilka, waxaan qeexi karnaa shuruudaha maraakiibta ama booyadaha waxaanan adeegsan karnaa heerarka badbaadada / dib u eegista iyo shuruudaha.
3. Tirada dalabka ugu yar
Haddii aad alaab ka soo iibsato mareegahayaga, tirada dalbashada ugu yar waa 30 tan.
4.Bixinta
Habka lacag bixinta caadiga ah ayaa si toos ah looga jarayaa 30 maalmood gudahooda laga bilaabo qaansheegta.
5. Dukumentiga keenista
Dukumeentiyada soo socda ayaa la keenay keenista kasta:
Bill of Lading, CMR Waybill ama dukumeenti gaadiid oo kale oo khuseeya
Shahaadada Falanqaynta ama waafaqsanaanta (haddii loo baahdo)
Dukumeenti la xidhiidha HSSE oo waafaqsan xeerarka
Dukumeenti kastamka oo waafaqsan xeerarka (haddii loo baahdo)
