Ukuphepha Okuphelele Ngesudi Ye-Sandblasting
Ukuqhunyiswa kwesihlabathi kungaba yindlela eyigugu yokulungisa indawo, kodwa uma isetshenziswa ngendlela engafanele ingabulala. Abasebenzi ngaphandle kokuvikelwa okufanele bangaba nezinkinga zokuphefumula, ukulimala kwamehlo kanye nokulimala kwesikhumba ngenxa yalokho. Ukuze bahlale bephephile emsebenzini kubalulekile ukuthi abasebenzi bathobele izindinganiso zokuphepha emsebenzini lapho benza lolu hlobo lomsebenzi.
Kunezixazululo zemishini ezitholakalayo zokunciphisa izingozi ezinjalo, futhi lesi sihloko sizohlola izesekeli ezine ezibalulekile ze-sandblasting ezizoqinisekisa ukuthi ama-blasters nezinye ezisesayithi zigcinwa ziphephile ekulimaleni.
Umshini wokuphefumula
Ama-respirators ayingxenye ebalulekile yegiya lokuphepha lapho iziqhumane ezomile zihlanganisa uthuli oluyingozi; ukuze ugcine uphefumula umoya ohlanzekile ngokuphepha. Kufanele zilingane kahle ebusweni ukuze zenze uphawu olungangenisi umoya futhi zihlolwe ngaphambi kokufakwa emsebenzini..
Abasebenzi abagqoke imaski yokuphefumula kufanele bahlose ukunciphisa ukuchayeka ngokusebenza ezindaweni ezinomoya omuhle.. Nakuba izilawuli zobunjiniyela ezifana nokukhipha umoya kufanele kusize ukunciphisa ukukhishwa kwekhabhoni, kwezinye izimo lokhu kungase kungasebenzi noma kungabizi kakhulu.
Ekupheleni kwawo wonke amashifu, abasebenzi abasebenzisa imishini yokuphefumula kufanele bayihlanze kahle futhi bayigcine. Qaphela izimpawu zokuguga ezinjengamaphethelo ocezu lobuso noma imiphetho egugile ezihlungini; futhi bheka iziqeshana ezikhwezwayo ezingekho; hlola ipayipi nezinamathiselo ukuze kutholakale imifantu, amakhefu noma ama-kinks; qinisekisa ukuthi isihlalo se-valve asinawo udoti; izihlungi kufanele zihlangabezane nemibandela ebekiwe yesimo sakho sengozi ethile emsebenzini;
Isigqoko sokuzivikela
Umsebenzisi ogqoke i-grit blasting udinga ukugqoka isigqoko sokuzivikela, ukuvikela isikhumba sakhe ekuchayekeni nasekuhogeleni izinhlayiya eziyingozi njenge-silica, i-zinc kanye nomthofu okhishwa ngesikhathi sokuqhunyiswa.
Izigqoko zokuzivikela eziqhumayo zihlinzekwa komoya ukuze ziqede ukuhogela kwezinhlayiya zothuli ezincane ezingase zibe yingozi empilweni yomuntu ophethe futhi zinikeze ukuvikeleka okwengeziwe ezintweni ezihuzukayo eziqhumayo kanye namazinga omsindo oweqisayo..
Izitokwe ezisetshenzisiwe Izigqoko zokuzivikela eziqhumayo ezigunyazwe yi-CE ezidizayinelwe ukusetshenziswa nemibhobho ehlukahlukene kanye nezinsiza. Inikeza kokubili ukuvikela nokunethezeka, lezi zigqoko zokuzivikela eziqhumayo zivumela ama-blasters ukuthi agxile ngokugcwele emsebenzini wawo ngamaleveli aphezulu okukhiqiza azuziwe. Ezinye izigqoko zokuzivikela zize zize zifakwe izici zikagesi noma zokuvikela ukuzwa esezihlanganisiwe ngaphakathi kwazo, ukonga imali ngokususa izinto zokuphepha ezihlukene okufanele zithengwe futhi ziphathwe ngokuhlukana.
Ikhava
Ukuhlala uphephile njengesisebenzi esisebenza endaweni eqhuma ngamandla kusho ukuwavikela ezingozini ezingokwemvelo kanye nobuthi obuyinsalela obusala ngemva kokuqhuma okubi.. Enye insalela enjalo enobuthi uthuli lwe-silica oluyikristalu, osekufakazelwe ukuthi adala umonakalo ongalungiseki futhi obulalayo wamaphaphu.
Ukuvikela abasebenzi ekuchayekeni ezinhlayiyeni zothuli lwe-silica, abasebenzi kufanele bagqoke amakhava angavimba uthuli ukungena kwezinhlamvu ezigqokwa ngaphansi. Isihlungi Somzimba Wethu 95+ ama-coverall anama-cuffs akhethekile aklanyelwe ukunamathisela kalula nokuhlukaniswa kwamagilavu, amabhuzu nezicathulo.
Amakhava ahlinzeka ngokuvikeleka okwengeziwe kuma-opharetha aqhumisayo ngokumelene nokwanda kokushisa, ama-abrasive doti, amakhemikhali nemililo evuthayo ebangelwa izinto ezivuthayo. Amakhava e-ECAB anikezela ngenhlanganisela efanele yokuvikela nokunethezeka ukuvumela isisebenzisi ukuthi sisebenze ngamandla abo aphezulu.
Amagilavu
Lapho usebenza ngezinto ezinobuthi ezi-abrasive, ama-blasters kufanele ahlale egqoke i-PPE. Lokhu kubandakanya ukugqoka imaski yobuso noma izibuko zokuphepha, umakalabha ohlinzekwa ngomoya, amagilavu enjoloba, amasudi okuqhuma enayiloni avumela ukuguquguquka futhi angawashwa ngomshini ukuze asetshenziswe okumanzi noma okuqhunyiswa ngumhwamuko, amagilavu enjoloba.
Njengoba ukuqhunyiswa kungadala amafu othuli abalulekile, kubalulekile ukuthi kuthathwe izinyathelo zokuphepha ezifanele ngesikhathi nangemva kwenqubo yokuqhuma ngakunye. Umshini wokuphefumula onesihlungi sothuli esisebenzayo kufanele sisetshenziswe ukuze kuncishiswe ukuhogela izinhlayiya ezincane ezincanyana kanye nokusebenzisa izigqoko zokuzivikela ezinobuso obubanzi njengesivikelo ezintweni eziqhumayo.. Enye i-PPE kufanele ifake amapulaki ezindlebeni okuvikela ukuzwa kanye namabhuzu anezinzwane zensimbi avikela izinyawo emfucumfucwini ewayo.. Hlola zonke izinto zokusebenza ngaphambi nangemuva komsebenzi ngamunye ukuze uthole izimpawu zokulimala ngokomzimba ngaphambi kokuqhubekela phambili nanoma yimuphi umsebenzi.
Amabhuzu
Amabhuzu, igqokwe njengengxenye yesudi eqhumayo, inikeze isivikelo ekuhutsheni futhi kufanele ihlangabezane ne-EN ISO 20345:2011 okujwayelekile kwezicathulo zokuphepha.
Abasebenzi abagqoke amabhuzu okuphepha anezinzwane zensimbi batholakale benciphisa kakhulu amathuba okulimala komkhumbi (ngokunciphisa okumaphakathi kwe 0.609 emkhunjini weziqukathi 2 futhi 0.308 emkhunjini weziqukathi 1; bobabili nezikhulu zezinyunyana ezahlukene), nokho ukunethezeka okuphakathi akuzange kunciphe ngokusetshenziswa kwazo.
Garner et al. [32] ithole ukuthi amabhuzu esikhumba anikeza ukuzinza okukhulu kwe-postural uma kuqhathaniswa namabhuzu e-rubber firefighter ngesikhathi somsebenzi weSimulated Fire Stair Climb., kanti i-Irmanska [60] ithole ukungaphatheki kahle okushisayo kanye nokunqwabelana komswakama lapho kusetshenziswa izinsimbi zoboya ezibhuthini zezicishamlilo. Ama-GRF ahlolwe kusetshenziswa amabhuzu amathathu nge-SBR, I-liner yenoveli ene-ventilation noma engenawo liner kanye ne-Boot 1 ibonise amazinga aphezulu okulayisha ngokushesha uma kuqhathaniswa namabhuzu womabili 2 futhi 3.
