Ngoko ke kufuneka kulungiselelwe kakhulu wonke umntu osebenza netoluene Polyol kunye no-isocyanate ukulula ukucacisa okugcinwa. Ukulungisa ukuba ngaphandle kokuthi wendlela yokuhlola kwaye nokubhala lokhu kunqumeke kakhulu kwi-safety yakho nokuba yasemva kwakho. Isipopo esisodwa sokusebenzela toluene isocyanate nguqukumbi lokuba kube ngenqanawe emfihlweni. Ukungenqanawe kuhle kungahleli iifhumo nenqanawe ezifana neziphathelwe zokushintsha xa ungene usebenzela. Ukulola ukubhala nokugcina toluene isocyanate ngendlela eyahlukileyo. Kuyinketho ephakeme ukwazi le, ngokupheleleyo ukusizo lwakho, kodwa usizo lwalabantu abanye obenziwe namandla angaphambili. Ngoko ke, fumana ukulula ukuba ungayibone ukuthi ubomi bomkhuhlane we-toluene isocyanate uya kuthiwa njengalokhu olunyelekanga, kwaye ukuba ufumane imisebenzi yokuthola okanye ukusixa, xa kulungile. Kunezigabhenjisi zokuthola nokuthola ukusetyenziswa kwe-toluene isocyanate ngemva koku
Izixhobo zayo zinakudala kwiqembu elibonakaleni, uzisebenziswe ekhaphazimeni nezilimi ezikhushwa. Ukuba uqondile, ungenzi ngokuphambili, kodwa amagama anguquka ngeendlela zakho eziqhathanisiweyo ngokusebenzela ukusetyenziswa kwemicali. I-toluene isothiyanet yiya kuhluke; inhale. Yeyinto engeyiya ukulindela umzimba wakho, iinyawo nezinye izinto ezinomsindo. Ukusetyenziswa kokugcineni kungabizwa ngamandla okuthile ngokwesonto. Ngokugcineni, ungayithola amandla akho amanje amanje xa usetyenziswa nenkululeko yokubona. Ngalokho, kufuneka uhlale kumgca wosizo olungempumelelo ngokuphambili xa usetyenziswa nen-toluene isothiyanet. Lomgca luhlaza ngokuphambili ingxenyekazi zokungena imigcebo yakho, i-goggles yokungena iinyawo nezinye izinto ezinomsindo kunye nomthwalo yokungena ukuya kumoya omkhulu. Ukuze uthole amandla akho, ungayityiswa ukukhutshwa kunye nokuhlukanisa ukusetyenziswa kunye nokuhlukanisa ukusetyenziswa.
Ukusetshenziswa kweToluene isocyanate ngalendaweni kufuneka kube useto oluhle oluhlola amafhumulo ama-dangerous okanye amavopha oza kuhlala kwiqhutywa ngeToluene polyol isocyanate . Izithelo eziqhutywa zikwazi ukugcinwa kwiqhobo lwendawo ngaphandle kokuthi iindlela zakuxhasa kakhulu ezikhoyo zibekwe umdlalo. Zizoba ukuba zihleli ukubhaleka kwezinyaniso ezifanele njengomphakathi wokushesha nokuvilayini vamile ngokulandelana noma yinto ekuseniyo, ngenxa yaloo moya. Kuningi lokuhlinzekela ukusebenza kwindawo engasetyenziswa ukukhuluma ndlela yokuhlala okanye ukusetshenziswa kwesiqinisekisi somdlalo sokuhlala sokuqhubeka izithelo ezinhlelwayo, njengesithuthi esetshenziswa amaxhobo asehlulekileyo, xa usenzo nge-toluene isocyanate ukwenza indlela enjongo ukuthi imdlalo yisafadi. Isithuthi sesethunywa esetshenziswa amaxhobo asehlulekileyo akwazi ukufumana ukusetyenziswa ukusuka kwezithelo ezinhlelwayo, ukuhamba nokuba kube yintlango ebukheliweyo phakathi kweendawo. Ngoku kulula ukuba ukukhuluma ndlela okungabona kakhulu kunye nokusetshenziswa kweziqinisekisi zokuhlala zingene ukuthi ziqukethe umdlalo omkhulu lokuhlala ngokupheleleyo xa ungene nge-chemicals njenge-toluene isocyanate.
Amathetho asesempumelelo sokugcina nokusebenzisa kwi-toluene Ethyl isocyanate zinekiswe ukubuka ukusukela imibuzo nokuhlola kwezinto esidingeni. Asikho ngamagcali okuthile ngenqanawe kunye nokuhlola kumthwalo wesikhephe. Bheka isixhobo esingcinane njalo xa uvumelela umthwalo wesikhephe somthetho sotoluene. Njengokusebenzisa amandla asebenzi ukuprotekisa iindlebe zakho, amaphupha ukuprotekisa izinye zamatsha, kunye nomphoyiso wemfuyo nezinye izinto. Kuningi lokuhlanganiswa ukufologa kokuthiwe ngokulandelwa imisebenzi esidingeni. Ngoko ke, kufuneka ugcine umthwalo wesikhephe somthetho sotoluene phakathi komhlaba ofumanekayo. Gcina kulesi sekhaya esiqhelekileyo kunye nokungasebenzi kakhulu. Ayishayiwe ngaphandle kwezinto ezinikeleyo, njengamanzi amahluke kunye nemibhalo ebalulekileyo, okungabangithi akufuneki ukugcina ngaphezulu kwesinye isikhathi. Kufuneka ufologe ifomu yomthwalo wesikhephe somthetho sotoluene ngokubanzi kuhambisana nokusetshentlwa kunye nokugcina. Ukwenza lokhu kudinga ukuthiwe ngokulandelwa imisebenzi yokubuka kanye nokuhlola kwezinto ezidingeni. Ndizobona ngoku qaphelene ukuthi ubheke ngendlela eyenza ukuthi uthole umthwalo wesikhephe wakho kwiqhawekazi lokuncane lokuba angavumela nawe kunye nenkxaso yakho.
Kufuneka uqinisekise ngemibuzo yezinto ezizenzakalelayo kwiqhutywa lokugcwalisa ukuba ufaka ku-toluene isocyanate, kunye nokuba ungene ntonina ukubusa. Iimbuzo ziqhutywa ngokushesha, kodwa zingabonisa amandla ekwamanzi, ukukhopha, ukusuka ngokuqhutywa, ukulamba umphumela, ukuphazama kwesithathu, kunye nomphandle komphilo. Ukuba uyona okanye umntu wenza amanani apha ngaphandle kwe-toluene isocyanate, kufuneka uhlanganiswe ngokusemva kwesicelo somphilo ngqo. Ngoku ke kufuneka udityelele i-911 okanye usebenzele esikhesini sentshaba leyo lokuhlola. Xa uvumelela ukubusa, uma ingxenye yethu, inyawo iyiphindaphindi ukuthi ibuye ngendlela eyayiphi ndlela yokuhlala kwe-toluene isocyanate. Ngaphezulu kwezinye izimali ezidingekayo, zizohlola ubude bokudibana nobuciko bokuhlanganiswa ngokubanzi. Ngenxa yalokho, uzoba ukuthi ubungena ngokushesha kunezinto ezizokwenza ukuthi umntu akufanele afike kwindaweni yokuhlola ngokupheleleyo.
Isiqumo sokuqinisekisa ukusetyenziswa kwe-toluene isocyanate ngokubhekeliseyo kwiqhuro. Izicwangciso eziqinisekisayo zineenkcukacha zonke izibopheleli zizodlulisa ukufakwa kokuthi akuziphumelele iintsinganiso nokuhlala phambi komoya omkhulu. Kwesiqinisekiso, kufuneka zikhethwe zonke izigaba ezinikezela etoluene isocyanate. Zofunekwe ukuba zithethwe ngezindlela ezidingekileyo ukusetshenziswa kwemicali. Kufuneka kunye nomthombo wokusetyenziswa kweendlela ezidingekayo. Ukusuka okanye ukuphuma amandla, kufuneka amandla apha asebenzayo nokuthola etoluene isocyanate azibhekelise ngaphandle kokuthi akudibanise noma akuphume. Izicwangciso neencwadi zakho zakwazi ukwenza ukuthi zonke izinhlobo zezimpilo zezilungiselelwe ngokubhekeliseyo kumhlaba ongathathwe ukusetshenziswa etoluene isocyanate. Ukusetyenziswa kukholelwanga kunye nokwaziwa kwezindlela ezidingekayo kuhleli imiphumela.
