Izidingo zezitini ezibusayo ziya ngokuya ziqinile, hhayi ngokwekhwalithi yekhwalithi, kepha futhi nangokwezithako zayo . Izidingo eziningi zisetshenziswa kakhulu futhi zisetshenziswa kumaphrojekthi amaningi ubumba, ubumba lobumba nokunye okufanayo, kepha izidingo ezilandelayo kumele zihlangatshezwe ukuze ziqinisekise ikhwalithi yayo:
1. Ukwakheka kwamakhemikhali zezithako zezitini ezisebenzayo kumele zihlangabezane nezidingo, futhi kufanele kube ngaphezulu kwezidingo zenkomba ezijwayelekile
2. Indlela yokucindezela eyomile ngokuvamile isetshenziswa ekukhiqizweni kwamanje kwezitini ezisebenzayo, ezidinga ukuthi izikhala zibe nezindawo ezibophayo ezanele, ngakho-ke izithako ezibophayo kufanele zifakwe ezithakweni;
3. Lapho impahla eluhlaza iqukethe izithako futhi zikhishwe izithako, kuzoba nobudlelwano bokuguqulwa phakathi kokwakheka kwamakhemikhali zezinto zokwakha, izithako kanye nezitini ezisebenzayo .
Izithako zezitini ezivusekiso zinezidingo eziqinile ngokuya ngezinkomba, izithako, izikhala, njll {0 Ingxenye yesizathu futhi ihlobene nezithako zayo ezihlangabezana nezidingo .
