Malangizo Oteteza Kuphulika kwa Abrasive

Pankhani yopanga ndi kumaliza, imodzi mwazinthu zofunika kwambiri ndi kuphulika kwa abrasive, komwe kumatchedwanso grit blasting, sandblasting, kapena media blasting. Ngakhale kuti dongosololi ndi losavuta, lingathenso kuonedwa kuti ndi loopsa ngati silikugwiritsidwa ntchito moyenera.

Pamene kuphulika kwa abrasive kunayambika, ogwira ntchito sanagwiritse ntchito njira zambiri zotetezera. Chifukwa chosowa kuyang'anira, anthu ambiri adayamba kudwala matenda opuma chifukwa chopuma fumbi kapena tinthu tina tomwe timatulutsa pakaphulika mowuma. Ngakhale kuphulika konyowa kulibe vuto limenelo, kumabweretsa zoopsa zina. Nawa tsatanetsatane wa zowopsa zomwe zingabwere chifukwa cha njirayi.

• Matenda Opumira -Monga tonse tikudziwira, kuphulika kouma kumapanga fumbi lambiri. Ngakhale malo ena ogwira ntchito amagwiritsa ntchito makabati otsekedwa kuti atenge fumbi, malo ena ogwira ntchito sagwiritsa ntchito. Ngati ogwira ntchito apuma fumbi ili, akhoza kuwononga kwambiri m'mapapo. Makamaka, mchenga wa silika ungayambitse matenda otchedwa silicosis, khansa ya m'mapapo, ndi vuto la kupuma. Malasha slag, copper slag, garnet sand,     nickel slag, ndi galasi zingayambitsenso kuwonongeka kwa mapapo mofanana ndi mchenga wa silica. Malo ogwira ntchito omwe amagwiritsa ntchito zitsulo amatha kupanga fumbi lapoizoni lomwe lingayambitse matenda kapena imfa. Zidazi zimatha kukhala ndi kuchuluka kwa zitsulo zapoizoni monga arsenic, cadmium, barium, zinki,     mkuwa, chitsulo, chromium, aluminiyamu, faifi tambala, cobalt, crystalline silica, kapena beryllium zomwe zimatuluka mpweya ndipo zimatha kukomoka.

• Kuwonetsedwa ndi phokoso-Makina ophulitsira abrasive amayendetsa tinthu tating'ono kwambiri, motero amafunikira ma mota amphamvu kuti azithamanga. Mosasamala mtundu wa zida zomwe zimagwiritsidwa ntchito, kuphulika kwa abrasive ndi ntchito yaphokoso. Magawo opondereza mpweya ndi madzi amatha kumveka mokweza kwambiri, ndipo kukhala pachiwopsezo kwa nthawi yayitali popanda chitetezo chakumva kumatha kupangitsa kuti makutu amve pang'ono kapena mpaka kalekale.

• Kupweteka kwapakhungu ndi kutupa -Fumbi lopangidwa ndi kuphulika kwa abrasive likhoza kulowa mu zovala mwamsanga komanso mosavuta. Pamene ogwira ntchito akuyendayenda, grit kapena mchenga ukhoza kupukuta pakhungu lawo, kupanga zotupa ndi zina zowawa. Popeza cholinga cha kuphulika kwa abrasive ndikuchotsa zinthu zapamtunda, makina ophulitsira amatha kukhala owopsa ngati atagwiritsidwa ntchito popanda kuphulika koyenera kwa PPE. Mwachitsanzo, ngati wogwira ntchito aphulitsa dzanja lake mwangozi, amatha kuchotsa khungu ndi minofu. Kupangitsa kuti zinthu ziipireipire,     tinthu tinthu timalowa m’thupi ndipo zimakhala zosatheka kutulutsa.

• Kuwonongeka kwa Diso -Tinthu tating'onoting'ono tomwe timagwiritsa ntchito pophulitsa abrasive nditing'ono kwambiri, kotero tikalowa m'diso la munthu, titha kuwononga kwambiri. Ngakhale malo otsukira m'maso amatha kutulutsa mbali zambiri, zidutswa zina zimatha kumamatira ndikumatenga nthawi kuti zituluke mwachilengedwe. Ndikosavuta kukandanso cornea, zomwe zingayambitse kutayika kwa masomphenya kosatha.

Kuphatikiza pa zonyansa, phokoso, ndi zovuta zowonekera, makontrakitala ophulika mafakitale amatha kuvulala mwakuthupi pogwiritsa ntchito makina osiyanasiyana komanso zoopsa zosiyanasiyana zomwe zingabisike kuzungulira malo ogwira ntchito. Komanso, zophulitsa nthawi zambiri zimafunika kugwirira ntchito m'malo ocheperako komanso pamalo otalikirapo kosiyanasiyana kuti azitha kuphulitsa moopsa.

Ngakhale ogwira ntchito ali ndi udindo wodzitetezera okha, olemba anzawo ntchito ayeneranso kusamala kuti aliyense atetezeke. Izi zikutanthauza kuti olemba anzawo ntchito akuyenera kuzindikira zoopsa zonse zomwe zingachitike ndikukhazikitsa njira zonse zowongolera kuti achepetse ngozi ntchito isanayambe.

Nawa njira zapamwamba zotetezera ntchito zomwe inu ndi antchito anu muyenera kutsatira monga mndandanda wa chitetezo chophulika.

• Kuphunzitsa ndi kuphunzitsa onse ogwira ntchito zophulitsa zophulika.MaphunziroZitha kukhala zofunikiranso kufotokoza momwe angagwiritsire ntchito makina ndi zida zodzitetezera (PPE) zomwe zimafunikira pantchito iliyonse.

• Kusinthitsa kuphulika kwa abrasive ndi njira yotetezeka, monga kuphulika konyowa, ngati kuli kotheka

• Kugwiritsa ntchito zowulutsira zosawopsa kwambiri

• Kulekanitsa malo ophulitsa ndi ntchito zina

• Kugwiritsa ntchito mpweya wokwanira kapena makabati ngati nkotheka

• Gwiritsani ntchito ndondomeko yoyenera yophunzirira nthawi zonse

• Kugwiritsa ntchito zosefedwa ndi HEPA-zosefera kapena njira zonyowa poyeretsa nthawi zonse malo ophulika

• Kusunga ogwira ntchito osaloledwa kutali ndi malo ophulika

• Kukonzekera kuphulika kwa abrasive panthawi yomwe nyengo ili bwino komanso pamene antchito ochepa alipo

Chifukwa cha kupita patsogolo kwaposachedwa kwaukadaulo wachitetezo cha abrasive blasting, olemba anzawo ntchito ali ndi mwayi wamitundu yosiyanasiyana yazida zotetezera zowononga. Kuchokera pa zopumira zapamwamba kupita ku maovololo otetezeka, nsapato, ndi magolovesi, zida zotetezera zophulika ndizosavuta kupeza.

Ngati mukuyang'ana kuti muveke antchito anu ndi zida zachitetezo chapamwamba kwambiri, zokhalitsa kwanthawi yayitali, lumikizanani ndi BSTEC pawww.cnbstec.comndikuyang'ana m'magulu athu ambiri a zida zotetezera.
