Hydroxyethyl methylcellulose (hemc) imagwiritsidwa ntchito poimba kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zamankhwala osiyanasiyana, chakudya, zodzola komanso zomangamanga. Amayamikiridwa chifukwa cha kukula kwake, emulsifyiming, mawonekedwe filimu, komanso kukhazikika. Ngakhale anali kugwiritsa ntchito kwambiri, poyambitsa chitetezo panthawi yake ndikugwiritsa ntchito ndikofunikira. Nayi njira zotetezera kwambiri pogwiritsa ntchito hydroxyethyl methylcelulose:
1. Kumvetsetsa nkhani
Hemc ndi etherse yopanda inic cellulose, cellulose ya cellulose komwe magulu a hydroxyl adasinthidwa pang'ono ndi hydroxyethyl ndi magulu a methyl. Kusintha kumeneku kumathandizira kusungunuka kwake komanso kugwira ntchito. Kudziwa ndi zinthu zake zamankhwala ndi thupi, monga kusubalili, mafakisoni, ndi kukhazikika, zimathandizira kugwiritsa ntchito mosamala.
2. Zida zoteteza (PPE)
Magolovesi ndi zovala zoteteza:
Valani magolovesi ozunza a mankhwala kuteteza khungu.
Gwiritsani ntchito zovala zoteteza, kuphatikiza malaya ndi thalauza, kuti mupewe kuwonekera khungu.
Chitetezo cha Maso:
Gwiritsani ntchito zotetezeka kapena zikopa za nkhope kuti muteteze fumbi kapena ma slanges.
Kuteteza Kupuma:
Ngati mukugwira hedc mu ufa, gwiritsani ntchito masks kapena kupuma kuti musawononge tinthu tating'onoting'ono.
3. Kusamalira ndi Kusunga
Mpweya wabwino:
Onetsetsani kuti mpweya wabwino m'malo mwa ntchito yogwira ntchito kuti muchepetse fumbi.
Gwiritsani ntchito mpweya wanu wamtundu wambiri kapena zowongolera zina zamagetsi kuti musunge mizere ya mpweya pansipa yomwe ikulimbikitsidwa.
Kusungira:
Sungani hemc mu malo ozizira, owuma kutali ndi chinyezi komanso dzuwa.
Sungani zimbalangondo zotsekedwa mwamphamvu kuti muchepetse kuipitsidwa ndi chinyezi.
Sungani kutali ndi zinthu zosagwirizana monga oxidizer.
Kusamalira Mosamala:
Pewani kupanga fumbi; gwira modekha.
Gwiritsani ntchito maluso oyenera ngati kunyowa kapena kugwiritsa ntchito otola fumbi kuti muchepetse tinthu tating'onoting'ono.
Kukhazikitsa zabwino zopangira nyumba kuti ateteze fumbi pamtunda.
4. SPIL ndi njira zotuta
Mapati ang'ono:
Tsekani kapena musatamizani zinthuzo ndikuyiyika chidebe choyenera.
Pewani zouma zouma kuti fumbi zilepheretse; Gwiritsani ntchito njira zodulira kapena zosefera za HPA.
Zida zazikulu:
Tulukani kuderalo ndikuyatsira mpweya.
Valani PPE yoyenera ndikukhala ndi matalala kuti musafalitsidwe.
Gwiritsani ntchito zida zanthert ngati mchenga kapena vermiculite kuti mutenge chinthucho.
Kutaya zinthu zomwe zasonkhanitsidwa molingana ndi malamulo am'deralo.
5. Zowongolera zowongolera ndi zaukhondo
Malire Othandizira:
Tsatirani Ntchito Yogwiritsa Ntchito Yabwino Kwambiri ndi Intery (OSHA) kapena Malangizo Oyenera a Padera Okhudza Kudziwonetsa.
Ukhondo:
Sambani manja atathana ndi hemc, makamaka musanadye, kumwa, kapena kusuta.
Pewani kukhudza nkhope yanu ndi magolovesi kapena manja awo.
6. Ziwopsezo zathanzi ndi njira zoyambira
Inhalation:
Kuwonekera kwa nthawi yayitali kumwamba kumatha kuyambitsa kupuma.
Sunthani munthu yemwe wakhudzidwayo kuti azikhala ndi mpweya wabwino ndikupita kuchipatala ngati zizindikiro zikupitilira.
Pakhungu:
Sambani malo omwe akhudzidwa ndi sopo ndi madzi.
Pitani kuchipatala ngati mkwiyo umakula.
Kulumikizana ndi Maso:
Maso akutsuka bwino ndi madzi osachepera mphindi 15.
Chotsani magalasi okhudzana ndi omwe alipo komanso osavuta kuchita.
Pitani kuchipatala ngati kukwiya kumapitilira.
Ingetion:
Itsuke pakamwa ndi madzi.
Musayime pokhapokha mutayang'aniridwa ndi ogwira ntchito azachipatala.
Sungafune kuchipatala ngati ndalama zambiri zimangodulidwa.
7.. Moto ndi zoopsa zophulika
Hemo siwoyaka kwambiri koma amatha kuwotcha ngati moto.
Kulimbana ndi Moto:
Gwiritsani ntchito utsi wamadzi, chithovu, mankhwala owuma, kapena kaboni dayokisaidi kuti musinthe moto.
Valani zida zotchinga kwathunthu, kuphatikizapo zida zodzipukuta nokha (scba), mukamamenya moto wophatikizira hemc.
Pewani kugwiritsa ntchito mitsinje yayitali yamadzi, yomwe imayala moto.
8. Kusamala kwachilengedwe
Pewani kutulutsidwa kwachilengedwe:
Pewani kutulutsidwa kwa hemc mu chilengedwe, makamaka m'madzi, monga momwe zimakhudzira anthu amizinda.
Kutaya:
Kutaya hemc malinga ndi kwanuko, boma, ndi federal.
Osataya m'madzi popanda chithandizo choyenera.
9. Zambiri
Kulemba ndi gulu:
Onetsetsani kuti hemoc herc amalembedwa moyenera malinga ndi mfundo zowongolera.
Dziwereleni nokha ndi pepala la chitetezo (ma sds) ndikutsatira malangizo ake.
Mayendedwe:
Tsatirani malangizowo kuti anyamule zotengera za hema, kuonetsetsa kuti zasindikizidwa ndi kutetezedwa.
10. Kuphunzitsa ndi Maphunziro
Kuphunzitsidwa kwa Wogwira Ntchito:
Patsani maphunziro oyenera, osungirako, ndi kutaya kwa hemc.
Onetsetsani kuti ogwira nawo ntchito akudziwa zoopsa zomwe zingatheke komanso kusamala.
Njira Zadzidzidzi:
Kukula ndi kulumikizana njira zadzidzidzi zokutira, kutayika, ndi kutulutsa.
Khazikitsani ndalama zokhazikika kuti muwonetsetse kukonzekera.
11. Kusamala kwazinthu
Zowopsa za Kupanga:
Kutengera ndi mawonekedwe ndi kukhazikika kwa hemc, mosamala zowonjezera zingakhale zofunikira.
Funsani malangizo azogulitsa ndi malingaliro a wopanga.
Maupangiri ogwiritsa ntchito:
Mu mankhwala opangira mankhwala, onetsetsani hemc ndi ya kalasi yoyenera yolowetsera kapena jakisoni.
Pomanga, dziwani kuti fumbi lomwe limapangidwa posakanikirana ndi kugwiritsa ntchito.
Potsatira njira zodzitchinjiriza, zoopsa zomwe zimakhudzana ndi kugwiritsa ntchito kwa hydroxethyl methylcellulose imatha kuchepetsedwa kwambiri. Kuonetsetsa kuti malo otetezeka osakhala otetezeka okha ogwira ntchito komanso amakhalabe ndi mtima wosagawanika kwa malonda ndi malo oyandikana nawo.
