Youma ndikusunga kutentha kwa firiji
1. Chiwiya: Gwiritsani ntchito mizere ya artight yopangidwa ndi zida zogwirizana, monga galasi kapena mapulasitiki ena. Onetsetsani kuti muli ndi zinthu zikulembedwa.
2. Malo osungirako: Sungani Perc munthawi yozizira, yokhazikika yolimbana ndi dzuwa, magwero otentha ndi malawi otseguka. Iyenera kusungidwa pamalo osungirako mankhwala.
3. Kutentha: Sungani kutentha kosungira mkati mwa magawo 15 ° C ndi 30 ° F ndi 86 ° F).
4. Kusagwirizana: Chonde pitirizani perc kutali ndi oxidants amphamvu, ma asidi ndi zitsulo, ndi zitsulo zogwira ntchito kuti mupewe zochita zowopsa.
5.
6. Zida zake zoteteza (PPE)
7. Kutsatira malamulo ndi malangizo akomwe kusungira zinthu zowopsa, kuphatikizapo zofuna zina zapadera za perlorethylene.
Inde, Tetrachlorethynene imavulaza anthu. Nazi mfundo zazikuluzikulu zokhudzana ndi zotsatira zake:
1. Kuwononga Mphamvu: Kupumira kwa mafupa a tetrachlorehthylene kungayambitse kupuma, chizungulire, kupweteka mutu, komanso m'malo okwera kwambiri, kungayambitse mphamvu ya manjenje.
2. Kukwiya kwa khungu ndi m'maso: Kulumikizana mwachindunji ndi tetrachlorethththynense kumatha kupweteketsa khungu ndipo kumayambitsa kukwiya kapena kuwonongeka.
3. Kuwonekera kwa nthawi yayitali: Kudziwitsidwa kwanthawi yayitali kapena mobwerezabwereza kumatha kuyambitsa matenda oopsa, kuphatikiza chiwindi ndi kuwonongeka kwa impso, ndipo kumawerengedwa ngati carcinogen ya anthu padziko lonse lapansi.
4. Mavuto a chilengedwe: Tetrachlorethylene imatha kuyipitsa mpweya, madzi, ndi nthaka, zomwe zimapangitsa kuti chilengedwe chikhale ndi chilengedwe.
