ʻO ka PCB (papa kaapuni paʻi) he papa kaapuni paʻi ʻia, ʻo ia kekahi o nā ʻāpana koʻikoʻi o ka ʻoihana uila. Mai nā uaki uila liʻiliʻi a me nā mīkini helu a hiki i nā kamepiula nui, nā lako uila kamaʻilio, a me nā ʻōnaehana mea kaua koa, inā he mau ʻāpana uila e like me nā kaapuni i hoʻohui ʻia, i mea e hana ai i ka pilina uila ma waena o nā ʻāpana like ʻole, e hoʻohana lākou i ka PCB.
No laila pehea e nānā ai i ka PCB me ka mīkini ana ʻike?
1. E nānā i ka ʻili PCB no ka pohō
I mea e pale aku ai i ka kaapuni pōkole, ʻo kona ʻili lalo, nā laina, ma o nā lua a me nā ʻāpana ʻē aʻe e pono e kaʻawale mai nā māwae a me nā ʻōpala.
2. E nānā i ka ʻili PCB no ke kūlou ʻana
Inā ʻoi aku ka piʻo o ka ʻili ma mua o kahi mamao, ua manaʻo ʻia he huahana kīnā
3. E nānā inā he ʻōpala tin ma ka lihi o ka PCB
ʻOi aku ka lōʻihi o ka slag tin ma ka lihi o ka papa PCB ma mua o 1MM, kahi i manaʻo ʻia he huahana hemahema.
4. E nānā inā maikaʻi ke kūlana o ka puka wili
Ma hope o ka hoʻopili paʻa ʻole ʻia ʻana o ka laina wili a i ʻole ka ʻili notch i ʻoi aku ma mua o 1/4 o ke awa wili, ua manaʻo ʻia he huahana hemahema.
5. E nānā inā he mau hewa, nā mea i haʻalele ʻia a i ʻole nā mea maopopo ʻole i ka paʻi pale o ke kikokikona ma ka ʻili
