Kuphatikiza apo, timatsata ndikuyang'anira zotumizidwa kuti zitsimikizire kuti zaperekedwa munthawi yomwe tikuyembekezeredwa.
Mwa kutsatira mosamalitsa miyeso iyi yowongolera, titha kutsimikizira kuti makasitomala athu alandila PCB yodalirika komanso yapamwamba kwambiri yosinthika yomwe imakwaniritsa zomwe akufuna.
Powombetsa mkota,kumvetsetsa njira yosinthira yopangira PCB ndikofunikira kwa opanga komanso ogwiritsa ntchito kumapeto. Potsatira mamangidwe osamala, kusankha zinthu, kukonzekera gawo lapansi, kachitidwe ka dera, msonkhano, kuyesa, ndi njira zopangira, opanga amatha kupanga ma PCB osinthika omwe amakwaniritsa miyezo yapamwamba kwambiri. Monga gawo lofunikira pazida zamakono zamakono, ma board osinthika amatha kulimbikitsa luso ndikubweretsa magwiridwe antchito pamafakitale osiyanasiyana.
