Mfundo Zoyendetsera Ntchito Pakupanga Malo Ogwirira Ntchito Zamakampani
Ergonomics ndi kuphunzira kugwirizana pakati pa anthu, ntchito, zida, ndi malo ogwirira ntchito. Munthawi yamafakitale, ergonomics ndi maziko ofunikira popanga malo ogwirira ntchito omwe ali otetezeka, omasuka, komanso ogwira ntchito bwino, komanso omwe angathe kuwonjezera zokolola. Mapangidwe a malo ogwirira ntchito omwe amanyalanyaza mfundo za ergonomic nthawi zambiri amabweretsa mavuto monga kutopa kwambiri, matenda a minofu ndi mafupa (MSDs), kuchepa kwa ubwino wa ntchito, komanso kuchuluka kwa ngozi. Chifukwa chake, kukhazikitsa mfundo za ergonomic mu kapangidwe ka malo ogwirira ntchito m'mafakitale sikuti ndi njira yokhayo, koma ndikofunikira kuti pakhale magwiridwe antchito okhazikika.
Nchifukwa chiyani ergonomics ndi yofunika kwambiri m'mafakitale?
Malo ogwirira ntchito m'mafakitale amadziwika ndi ntchito yovuta: zochita zobwerezabwereza, kunyamula zinthu zolemera, kuyimirira kwa nthawi yayitali, kugwedezeka, phokoso, kutentha kwambiri, komanso kugwiritsa ntchito makina ndi zida zomwe zingakhale zoopsa. Popanda kapangidwe koyenera, ogwira ntchito amakonda kukhala ndi machitidwe osazolowereka—kugwada, kupotoza m'chiuno, kugwira zinthu mopitirira muyeso, kapena kugwira katundu m'malo olakwika. Matendawa angayambitse kuvulala kwakanthawi kochepa monga kuvulala kapena kuvulala, komanso mavuto a nthawi yayitali monga kupweteka kwa msana, matenda a carpal tunnel, ndi matenda a mafupa.
Ergonomics imathandiza kuchepetsa zoopsazi mwa kusintha ntchito kuti igwirizane ndi luso la anthu ndi zofooka zawo. Mwa kuyankhula kwina, ergonomics imalimbikitsa mfundo ya "kukwaniritsa ntchitoyo kwa munthuyo," m'malo mokakamiza anthu kuti azolowere kapangidwe koipa ka ntchito.
Mfundo zazikulu za ergonomics pakupanga malo ogwirira ntchito m'mafakitale
1. Sinthani miyeso ya malo ogwirira ntchito kuti igwirizane ndi anthropometry ya wantchito.
Anthropometry ndi deta yokhudza muyeso wa thupi la munthu, monga kutalika, kufikira dzanja, kutalika kwa chigongono poyimirira kapena kukhala pansi, ndi kutalika kwa mkono. Deta iyi imagwiritsidwa ntchito kudziwa kutalika kwa benchi yogwirira ntchito, malo owongolera, malo olumikizira mabatani, kukula kwa chogwirira cha zida, ndi kutalika kwa shelufu yosungiramo zinthu.
Mu mafakitale, malo ogwirira ntchito amapangidwa bwino kuti agwirizane ndi kukula kwa antchito osiyanasiyana—nthawi zambiri pogwiritsa ntchito mfundo za percentile (monga, percentile ya 5 mpaka percentile ya 95). Izi zikutanthauza kuti malo ogwirira ntchito amapangidwa kuti agwirizane ndi antchito ambiri, osati antchito "apakati" okha. Ngati kusiyana kwa kukula kwa antchito kuli kwakukulu, mapangidwe osinthika ndiye yankho labwino kwambiri, monga madesiki osinthika kapena mipando yosinthika kutalika.
2. Sungani kaimidwe kosagwirizana ndi mbali ina iliyonse yogwirira ntchito ndipo chepetsani mayendedwe owopsa.
Kaimidwe kopanda mbali ndi malo achilengedwe kwambiri a thupi ndipo amachepetsa kupsinjika kwa minofu ndi mafupa. Pakupanga mafakitale, cholinga cha ergonomics ndikuchepetsa zinthu monga kugoba kwa nthawi yayitali, kupendekera kwambiri khosi, mapewa okwezedwa, kapena manja opindika. Malo abwino ogwirira ntchito amaika zinthu zogwirira ntchito pamalo okwera komanso patali, zomwe zimathandiza ogwira ntchito kugwira ntchito ndi msana wowongoka, mapewa omasuka, ndi manja owongoka.
Mwachitsanzo, ntchito yomanga zigawo zazing'ono iyenera kuchitika pakati pa kutalika kwa m'chiuno ndi pachifuwa, kuti ogwira ntchito asapindike kapena kukweza manja awo m'mwamba kwambiri. Pa ntchito zomwe zimafuna mphamvu zambiri, malo ogwirira ntchito amatha kuchepetsedwa pang'ono kuti ogwira ntchito athe kugwiritsa ntchito mphamvu pogwiritsa ntchito kulemera kwa thupi lawo mosamala kwambiri.
3. Kuchepetsa katundu wofunikira pogwiritsa ntchito makina ndi zipangizo zothandizira
Kunyamula, kukankhira, kukoka, ndi kunyamula katundu ndi gwero lalikulu la kuvulala kwa mafakitale. Mfundo zoyendetsera bwino zimalimbikitsa kugwiritsa ntchito zipangizo zothandizira monga zokweza, zonyamulira, mapaleti amanja, matebulo okweza, kapena manja a robotic kuti achepetse ntchito yonyamula katundu ndi manja. Ngati kunyamula ndi manja sikungapeweke, kapangidwe kake kayenera kuganizira kulemera kotetezeka kwambiri, kuchuluka kwa kunyamula katundu, mtunda woyenda, ndi kuthekera koyendetsa katundu komwe kulipo.
Kuphatikiza apo, zipangizo ndi zigawo ziyenera kuyikidwa pafupi ndi malo ogwirira ntchito momwe zingathere kuti antchito asayende mtunda wautali kapena kufikira kwambiri. Mashelufu omwe ali otsika kwambiri kapena okwera kwambiri amawonjezera chiopsezo cha kuvulala mwa kukakamiza ogwira ntchito kuti awerama kapena kufikira pamwamba.
4. Chepetsani ntchito yobwerezabwereza ndipo perekani ntchito zosiyanasiyana
Kuyenda mwamphamvu komanso mobwerezabwereza—monga kukanda, kukanikiza ma lever, kapena zinthu zolongedza—kungayambitse kutopa kwa minofu ndi kuvulala mopitirira muyeso. Ergonomics imalimbikitsa kuti mapangidwe a ntchito aziphatikizapo kusintha kwa mayendedwe ndi kusweka pang'ono. Kusinthana kwa ntchito kungagwiritsidwenso ntchito, kuti magulu omwewo a minofu asagwiritsidwe ntchito nthawi zonse panthawi yonse yogwira ntchito.
Pakupanga malo ogwirira ntchito, izi zitha kuthandizidwa ndi kukonza njira zomwe zimapatsa mwayi wosintha malo (kukhala pansi ndi kuyimirira), kugwiritsa ntchito zida zodzichitira zokha pantchito zobwerezabwereza, ndikukhazikitsa zolinga zenizeni zopangira zinthu malinga ndi luso la anthu.
5. Pangani kapangidwe kogwira mtima komanso kotetezeka
Mapangidwe a malo ogwirira ntchito m'mafakitale amakhudza kuyenda kwa zinthu, mtunda woyenda wa ogwira ntchito, zoopsa za kugundana, ndi kuyenda kwa njira. Mfundo zoyendetsera bwino zimalimbikitsa mapangidwe omwe amachepetsa masitepe osawonjezera phindu, amachepetsa kufunikira kopotoza thupi kwambiri, ndikuwonetsetsa kuti magalimoto oyenda pansi ndi mafakitale asiyana bwino (forklifts).
Malo ogwirira ntchito amafunikanso malo okwanira oyendera, njira yosavuta yotulukira, malo owoneka bwino a zida zadzidzidzi, komanso njira yoyenera yolumikizira chingwe ndi payipi kuti apewe ngozi. Kapangidwe kabwino sikuti kamangofulumizitsa ntchito komanso kumachepetsa nkhawa ndi chiopsezo cha ngozi.
6. Konzani zinthu zachilengedwe: kuwala, phokoso, kutentha, ndi kugwedezeka
Malo osasangalatsa a thupi angachepetse kuyang'ana kwambiri ndikuwonjezera chiopsezo cha zolakwika kuntchito. Kuwala kosakwanira kungayambitse kutopa kwa maso, pomwe kuwala kochulukirapo ndi kuwala kowala kungasokoneze kulondola. Mwachitsanzo, pa ntchito yowunikira bwino, kuwala kuyenera kupangidwa kuti kukwaniritse zosowa za maso kuti zolakwika za chinthu ziwonekere popanda kupsinjika maso.
Phokoso m'mafakitale liyeneranso kulamulidwa pogwiritsa ntchito njira zochepetsera phokoso, kukonza makina, ndi kapangidwe kabwino ka chipinda. Ngati phokoso silingathe kuthetsedwa, kugwiritsa ntchito zoteteza kumva (zotchingira makutu/zotchingira makutu) kuyenera kuphatikizidwa ndi kasamalidwe koyenera ka kuwala kuti zitsimikizire kuti kulankhulana bwino ndi chitetezo kukugwira ntchito.
Kutentha kwambiri kungayambitse kutopa ndi kusowa madzi m'thupi, pomwe kutentha kwambiri kungayambitse kuchepa kwa minofu ndikuwonjezera chiopsezo cha kuvulala. Kugwedezeka kuchokera ku makina kapena zida zogwiritsidwa ntchito m'manja kuyenera kulamulidwa, chifukwa kukhala nthawi yayitali kungawononge mitsempha yamagazi ndi mitsempha.
7. Mawonekedwe a makina ozungulira anthu ndi kapangidwe ka gulu lowongolera
Mu mafakitale amakono, ogwira ntchito amalumikizana kwambiri ndi ma control panels, ma Human Machine Interface (HMI) displays, mabatani, ma levers, ndi ma alarm. Ergonomics imagogomezera kuti ma interfaces ayenera kukhala osavuta kumva, ogwirizana, ndikuchepetsa mwayi wolakwitsa. Zolemba ziyenera kukhala zomveka bwino, zizindikiro zofunika ziyenera kuwoneka mosavuta, ndipo ma alarm ayenera kusiyanitsidwa ndi kufulumira.
Kuyika kwa gulu kuyeneranso kuganizira kufikira ndi mzere wowonekera. Ngati mabatani adzidzidzi ndi ovuta kuwafikira kapena zizindikiro zofunika sizikuwoneka, chiopsezo cha kuchedwa kuyankha chimawonjezeka.
Njira zokhazikitsira ergonomics mumakampani
Kugwiritsa ntchito mfundo za ergonomic kumafuna njira yolongosoka. Gawo loyamba nthawi zambiri limaphatikizapo kuzindikira mavuto kudzera mu kuwona ntchito, kuyankhulana ndi ogwira ntchito, zambiri za ngozi, ndi madandaulo okhudza kupweteka kwa minofu. Izi zimatsatiridwa ndi kuwunika zoopsa pogwiritsa ntchito njira monga RULA, REBA, kapena NIOSH Lifting Equation (kutengera mtundu wa ntchito). Zotsatira za kuwunikazi zimakhala maziko a malingaliro okonza—kuphatikizapo kuwongolera kwaukadaulo, kuwongolera kwa oyang'anira, ndi maphunziro a ogwira ntchito.
Maphunziro ndi ofunikira, koma si njira yokhayo yothetsera mavuto. Mu ulamuliro wowongolera zoopsa, kusintha kwa kapangidwe ndi zida zogwirira ntchito nthawi zambiri kumakhala kothandiza kwambiri kuposa kudalira njira ndi machitidwe okha. Chifukwa chake, ergonomics iyenera kuganiziridwa kuyambira pachiyambi cha kapangidwe ka malo ndi mizere yopangira, m'malo mongokonzedwa mavuto akangobuka.
Mapeto
Mfundo za ergonomic mu kapangidwe ka malo ogwirira ntchito m'mafakitale cholinga chake ndikupanga machitidwe ogwirira ntchito omwe amagwirizana ndi luso la anthu. Mwa kuganizira za anthropometry, kaimidwe kantchito kopanda tsankho, kuchepetsa kupsinjika kwa thupi, kuwongolera ntchito yobwerezabwereza, mapangidwe otetezeka, malo abwino ogwirira ntchito, komanso mapangidwe osavuta kugwiritsa ntchito makina, makampani amatha kuchepetsa chiopsezo cha kuvulala pomwe akuwonjezera zokolola ndi ubwino. Ergonomics si ndalama zowonjezera, koma ndi ndalama zomwe zimawononga nthawi yayitali zomwe zimakhudza kwambiri chitetezo cha ogwira ntchito, magwiridwe antchito, komanso moyo wabwino.
