Makampani opanga magalasi amagwiritsidwa ntchito kupanga mkaka wachikasu pigment.Yellow pigment yomwe imagwiritsidwa ntchito pamakampani opanga mapepala.Amagwiritsidwa ntchito ngati mordant m'makampani osindikizira ndi opaka utoto.Makampani opanga ma inorganic amagwiritsidwa ntchito kupanga mchere wina wa lead ndi lead dioxide.Makampani opanga mankhwala amagwiritsidwa ntchito popanga astringents ndi zina zotero.Makampani opanga benzene amagwiritsidwa ntchito ngati chofufutira.Makampani opanga zithunzi amagwiritsidwa ntchito ngati chodziwitsira zithunzi.Amagwiritsidwa ntchito ngati ore flotation agent m'makampani amigodi.Kuphatikiza apo, imagwiritsidwanso ntchito ngati oxidant popanga machesi, zowombera moto, zophulitsa, komanso zowunikira mankhwala.
Njira zodzitetezera: kutseka ntchito ndikulimbitsa mpweya wabwino.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Ndibwino kuti ogwira ntchito azivala masks odziteteza okha ngati fumbi, magalasi oteteza mankhwala, zovala za gasi zomatira ndi magolovesi a neoprene.Pewani kuyatsa ndi magwero otentha.Kusuta ndikoletsedwa kwambiri kuntchito.Khalani kutali ndi zinthu zoyaka ndi zoyaka.Pewani kupanga fumbi.Pewani kukhudzana ndi zochepetsera.Gwirani mosamala kuti mupewe kuwonongeka kwa zotengera ndi zotengera.Zida zozimitsira moto ndi zida zochizira mwadzidzidzi zamitundu yofananira ndi kuchuluka kwake zidzaperekedwa.Chidebe chokhuthulacho chikhoza kukhala ndi zinthu zovulaza.
Njira zosungirako: sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino.Pewani kuyatsa ndi magwero otentha.Kuyika ndi kusindikiza.Idzasungidwa mosiyana ndi zinthu zoyaka (zoyaka), zochepetsera ndi mankhwala odyedwa, ndipo kusungirako kosakanikirana ndikoletsedwa.Malo osungiramo zinthu adzakhala ndi zipangizo zoyenera kuti zikhale ndi kutayikira.
