Njira yosungira
Malangizo Osungira: Sungani m'nyumba yosungiramo zinthu yozizira komanso yopuma mpweya. Sungani kutali ndi moto ndi magwero a kutentha. Mapaketi ake ndi otsekedwa. Ayenera kusungidwa padera ndi zinthu zowononga mpweya, zochepetsera kutentha, alkalis, ndi mankhwala ophera tizilombo, ndipo pewani kusungiramo zinthu zosiyanasiyana. Ayenera kukhala ndi mitundu yofanana ndi kuchuluka kwa zida zozimitsira moto. Zipangizo zoyenera ziyenera kupezeka m'malo osungiramo zinthu kuti zisatayike.
Cholinga
Amagwiritsidwa ntchito popanga DSD acid, p-nitrobenzoic acid, p-nitrophenyl acetic acid, p-nitrotoluene orthosulfonic acid, p-methylaniline, 2,4-dinitrotoluene, 4-methyl-1,3-benzene Diamine, 2-amino-4-chloro-5-methylbenzenesulfonic acid, 4,4′-diaminostilbene-2,2′-disulfonic acid ndi 2-chloro-4-aminotoluene, zopangidwa mofooka. Acid green GS, red base GL, toluene diisocyanate; benzidine; 2-nitro-p-toluidine; 3-chloro-4-nitrotoluene; dinitrotoluene, ndi zina zotero, zomwe zimagwiritsidwanso ntchito ngati zopaka utoto, mankhwala ophera tizilombo, ndi mankhwala, zopaka utoto zowonjezera pulasitiki ndi ulusi wopangidwa.
