Ekukhiqizeni ikhwalithi yekhwalithi ye-PCB, kufanele kuhlolwe izici eziningana ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana namazinga adingekayo. Lezi zici zifaka:

1

2. Ubukhulu bokulawula: hlola ubukhulu be-PCB, uqinisekise ukuthi ihlangabezana nemininingwane edingekayo.

3

I-4. Ikhwalithi ye-Welding: hlola ikhwalithi yokuhlanganiswa kwe-soler, kufaka phakathi amasekethe amafushane, ukugcwaliswa komoya, nezinsalela, phakathi kwezinye izici.

I-5. I-Pay Lay Devisity: Qinisekisa ukuthi ucingo nezimbobo ezisebhodini zivulekile futhi zicacile, kufaka phakathi izimbobo zokumba kanye nezimbobo ezikhuphukayo.

I-6. Ikhwalithi yokubukeka: Bheka ikhwalithi yokubukeka kwe-PCB, kufaka phakathi ukukkena, imifantu kanye nokukhubazeka, phakathi kwezinye izici.

7

Ikhwalithi yokupakisha: Hlola ikhwalithi yokufaka i-PCB, kufaka phakathi ukuthi ayinakulwa futhi imelana nomswakama.

Ukuhlola lezi zici ezibalulekile ngesikhathi sokulawulwa kwekhwalithi ye-PCB kubalulekile ukugwema iziphambeko futhi uqinisekise ukuthi umkhiqizo wokugcina uhlangabezana nemininingwane edingekayo. Ngokusebenzisa izindlela zokulawula ezisezingeni elifanele, abakhiqizi be-PCB bangathuthukisa ikhwalithi nokwethenjwa kwemikhiqizo yabo, behlisa amaphutha angaba khona kanye nokunciphisa izindleko ezihambisana nokusebenza kabusha nokukhumbula.
