He aha nā mea palekana e pono ai mākou e makaʻala i ka wā e wili ai?

He aha nā mea palekana e pono ai mākou e makaʻala i ka wā e wili ai? I kekahi manawa e alakaʻi kēia mau haʻalele i nā pōʻino, no laila e hoʻāʻo mākou e hana i nā pōʻino ma mua o ka pua ~ Ma muli o nā wahi hana he ʻokoʻa loa, a ua hana ʻia ka uila, ka māmā, ka wela a me nā lapalapa ahi i ka hana, aia nā ʻano pōʻino. i ka hana wiliwili.
1, He mea maʻalahi ke kumu i nā pōʻino uila.
I ke kaʻina hana hoʻoheheʻe, no ka mea e pono pinepine nā welders e hoʻololi i ka electrode i uhi ʻia a hoʻoponopono i ke ʻano o ka welding, pono lākou e hoʻopili pololei i nā electrodes a me nā papa polar i ka wā o ka hana, a ʻo ka mana welding maʻamau ʻo 220V / 380V. Ke hewa ka mea pale pale uila, ʻaʻole kūpono nā ʻatikala pale hana, a ke hana hewa nei ka mea hoʻohana, hiki ke hoʻoulu i nā pōʻino uila. I nā hihia o ke kuʻi ʻana i nā pahu metala, nā pipeline a i ʻole nā ​​​​wahi pulu, ʻoi aku ka nui o ka pilikia o ka haʻalulu uila.

2, He mea maʻalahi ke kumu o ke ahi a me ka pahū.
No ka mea e hoʻopuka ʻia ka arc uila a i ʻole ka lapalapa ahi i loko o ke kaʻina hana welding, maʻalahi ke hana i ke ahi i ka wā e hana ai i nā wahi me nā mea hiki ke ahi. ʻOi aku ka maikaʻi ma nā wahi mea puhi ahi a me nā mea pahū (me nā lua, nā ʻauwai, nā ʻauwaha, a me nā mea ʻē aʻe), ʻoi aku ka pōʻino i ka wā e wili ai i nā ipu, nā hale kiaʻi, nā pahu a me nā paipu i mālama ʻia i nā mea pahū a pahū.

3, He mea maʻalahi ke kumu o ka electro-optic ophthalmia.
Ma muli o ke kukui ʻike ikaika ʻia a me ka nui o nā kukuna ultraviolet ʻike ʻole ʻia i hana ʻia i ka wā wili, he hopena ikaika a hoʻopōʻino i nā maka o nā kānaka. ʻO ka hoʻomālamalama ʻana i ka manawa lōʻihi e hoʻoulu ai i ka ʻeha o ka maka, photophobia, waimaka, makaʻu i ka makani, a me nā mea ʻē aʻe, a maʻalahi ke alakaʻi i ka mumū o ka conjunctiva a me ka cornea (i ʻike ʻia ʻo electro-optic ophthalmia).
ʻO ke kukui arc i hana ʻia i ka kuʻi ʻana me ka radiation māmā he mau kukuna infrared, nā kukui ultraviolet a me nā kukui ʻike ʻia, a he hopena radiation i ke kino kanaka. Loaʻa iā ia ka hana o ka radiation infrared, ka mea maʻalahi e alakaʻi i ka heatstroke i ka wā e hoʻopili ai i kahi kaiapuni kiʻekiʻe. Loaʻa i ka hana photochemical o nā kukuna ultraviolet, he mea ʻino ia i ka ʻili o nā kānaka, a ma ka manawa like, ʻo ka lōʻihi o ka hoʻolaha ʻana i ka ʻili i hōʻike ʻia e hana pū ai ka ʻili ʻili.

4, He mea maʻalahi ka hāʻule mai kahi kiʻekiʻe.
E like me ka hana kūkulu ʻana, pono e piʻi pinepine nā welders i kiʻekiʻe no ka hana wili. Inā ʻaʻole kūpono nā ana no ka pale ʻana i ka hāʻule ʻana mai kahi kiʻekiʻe, ʻaʻole i hoʻohālikelike ʻia ka scaffolding a hoʻohana ʻia me ka ʻole o ka ʻae ʻia. Lawe i nā hana kaʻawale e pale aku i ka paʻi ʻana o nā mea i ka hana kea; ʻAʻole ʻike nā welders i ka palekana palekana pilikino, a ʻaʻole e komo i ka mahiole palekana a i ʻole ke kāʻei palekana i ka wā e piʻi ai.

5, ʻO nā welders uila e maʻalahi i ka ʻawaʻawa a me ka hoʻoluhi pinepine ʻana e pono e komo i nā wahi i pani ʻia a i ʻole semi-pani ʻia e like me nā pahu metala, nā lako, nā paipu, nā hale kiaʻi a me nā pahu mālama no ka wili. Inā mālama ʻia, lawe ʻia a hana ʻia paha nā mea ʻona a me nā mea ʻino a me nā kinoea inert, i ka wā ʻilihune o ka hoʻokele hana, ʻaʻole i hoʻokumu ʻia nā hana pale, e maʻalahi ai ka make a i ʻole hypoxia a me ka ʻūhā o nā mea hana. , ʻoihana kemika a me nā ʻoihana ʻē aʻe.
