1. Chidebe: Sungani TMG mu chidebe chosindikizidwa kuti mupewe kuipitsidwa ndi kutuluka. Gwiritsani ntchito zotengera zopangidwa ndi zida zomwe zikugwirizana ndi zigawo zamphamvu.
2. Kutentha: Sungani TMG mu malo ozizira, owuma kutali ndi dzuwa ndi kutentha. Kutentha kwa chipinda nthawi zambiri kumakhala koyenera, koma kuyenera kusungidwa pansi pa 25 ° C (77 ° f) nthawi iliyonse yomwe angathe.
3. Chinyezi: chifukwa TMG ndi hygroscopic (imatenga chinyezi kuchokera mlengalenga), ndikofunikira kusungitsa chinyezi chochepa kuti chisalepheretse chinyezi.
4. Kusamala: Onetsetsani kuti malo osungirako ali ndi mpweya wabwino ndikuchita njira zoyenera ngati TMG itha kukwiyitsa khungu ndi maso.
5. Zizindikiro: Zolemba bwino zopezeka ndi dzina la mankhwala, kudera nkhawa, komanso chidziwitso chilichonse chowopsa.
Tetramethylguanine (TMG) imatha kukhala yovulaza thupi laumunthu ngati mosamala sikutenga. Nazi mfundo zazikuluzikulu zokhudzana ndi chiwopsezo ndi chitetezo:
1. Kukhumudwitsa: TMG imatha kukwiyitsa khungu, maso, ndi kupuma thirakiti. Kulumikizana mwachindunji ndi madzi kumatha kuyambitsa kutentha kwa mankhwala kapena kukwiya.
2. Inhalation: inhalation ya TMG Vapor ikhoza kuyambitsa kupuma komanso zovuta zina.
3. Kugwira Ntchito: Kuchepetsa TMG kungakhale kovulaza ndipo kungayambitse kupsinjika kwa m'mimba kapena zovuta zina.
4. Kusasamala: Mukamasamalira TMG, nthawi zonse gwiritsani ntchito zida zoyenera (PPE) monga magolovesi, zigawenga, ndi chovala chabu. Gwirani ntchito m'malo opumira kapena kugwiritsa ntchito bood kuti muchepetse kuwonekera.
5. Thandizo Loyamba: Ngati mwapezeka ndi mankhwala osokoneza bongo, tengani njira zoyambirira zothandizira, monga kupumula malo omwe akukhudzidwa ndi madzi ndikufufuza chithandizo chamankhwala ngati kuli kofunikira.
Mukamaika tetramethylguanine (TMG), mosamala zina kuyenera kutengedwa kuti zitsimikizidwe kuti ndi chitetezo ndikutsatira malamulo. Nayi malingaliro akuluakulu omwe mungaganizire:
1. Kutsatirana kwa ulamuliro: Onani ndikutsatira malamulo adziko lonse, komanso malamulo apadziko lonse lapansi okhudza mayendedwe owopsa. TMG ikhoza kutchulidwa ngati zinthu zowopsa, kotero onetsetsani kuti zolemba zonse zotumizira ndizolondola komanso zokwanira.
2. Ma Cantraing: Gwiritsani ntchito zida zoyenera za padentio yomwe ikugwirizana ndi TMG. Zotengera ziyenera kukhala zotabwa komanso zopangidwa ndi zida zomwe zimatha kupirira mapangidwe a mankhwala. Gwiritsani ntchito zisindikizo za sekondale kuti muchepetse kutaya.
3. Zolemba: Zolemba momveka bwino za dzina la mankhwala, chizindikiro chowononga, ndi chidziwitso chilichonse chothandiza. Izi zikuphatikiza kugwiritsa ntchito malangizo ndi chidziwitso chadzidzidzi.
4. Kuwongolera kutentha: Onetsetsani kuti zinthu zotumizira zimasunga kutentha kokhazikika, chifukwa kutentha kwambiri kungakhudze kukhazikika kwa TMG.
5. Pewani chinyezi: Popeza tmg ndi hygroscopic, chonde onetsetsani kuti phukusi ndi chinyezi chosonyeza kuti madzi amayamwa panthawi yoyendera.
6. Njira yoyendera: Sankhani njira yoyenera (nthaka, mpweya, nyanja) yomwe imagwirizana ndi malamulo owopsa. Onetsetsani kuti galimoto yoyendera imagwirizana ndi zida zofunika kuti zigwire katundu woopsa.
7.. Onetsetsani kuti ogwira ntchito omwe akutenga nawo mbali amaphunzitsidwa kuti azigwira zida zowopsa.
8. Zolemba: Izi zikuphatikiza zolemba zonse zotumizira monga kulipira ngongole, pepala la chitetezo (sds) ndi zilolezo zilizonse zofunika kapena zolengeza.
