Kwishishini le-oyile negesi sitofa iikhemikhali ngendlela:
• ukukhusela iziseko zophuhliso
• ukwandisa iinkqubo
• ukuqinisekisa ukuhamba
• kunye nokuphucula imveliso
Amachiza asetyenziswa kwimibhobho, iitanki, oomatshini kunye nemithombo yamanzi.Kubalulekile ukunqanda imingcipheko ezayo kunye neenaliti.Iikhemikhali ezincinci kakhulu zinokukhokelela kumaxesha okwehla okanye ukwenza ukuvaleka kolwelo, imichiza eninzi kakhulu inokonakalisa isiseko kwaye ikhokelele kwiitanki zonikezelo ezingenanto okanye ibe nzima inkqubo yohlaziyo.Kukwamalunga nokuxinana okuchanekileyo kwemveliso kunye nokudibanisa okuchanekileyo kweekhemikhali ezininzi.
