Manja amagwira ntchito yofunika kwambiri pakupanga ntchito. Komabe, manja ndi ziwalo zomwe zimavulazidwa mosavuta, zomwe zimawerengera pafupifupi 25% ya chiwerengero cha kuvulala kwa mafakitale. Moto, kutentha kwambiri, magetsi, mankhwala, zowononga, mabala, mikwingwirima, ndi matenda amatha kuvulaza manja. Kuvulala pamakina monga kukhudzidwa ndi kudulidwa kumakhala kofala, koma kuvulala kwamagetsi ndi kuvulala kwa radiation kumakhala kowopsa kwambiri ndipo kungayambitse kulumala kapena kufa kumene. Pofuna kuteteza manja a ogwira ntchito kuti asavulazidwe panthawi ya ntchito, ntchito ya magolovesi otetezera ndiyofunika kwambiri.
Miyezo yowunikira ma gloves oteteza
Mu Marichi 2020, European Union idasindikiza mulingo watsopano:EN ISO 21420: 2019Zofunikira zonse ndi njira zoyesera zamagolovesi oteteza. Opanga magolovesi oteteza ayenera kuonetsetsa kuti zinthu zomwe zimagwiritsidwa ntchito popanga zinthu sizikhudza thanzi la ogwira ntchito. Muyezo watsopano wa EN ISO 21420 umalowa m'malo mwa muyezo wa EN 420. Kuphatikiza apo, EN 388 ndi imodzi mwamiyezo yaku Europe yamagolovu oteteza mafakitale. European Committee for Standardization (CEN) idavomereza mtundu wa EN388:2003 pa Julayi 2, 2003. EN388:2016 idatulutsidwa mu Novembala 2016, m'malo mwa EN388:2003, ndipo mtundu wowonjezera EN388:2016+A1:2018 unasinthidwanso mu 2018.
Miyezo yofananira ya magolovesi oteteza:
TS EN 388: 2016 Muyezo wamakina wamagolovu oteteza
TS EN ISO 21420: Zofunikira zonse za 2019 ndi njira zoyesera zamagolovu oteteza
TS EN 407 Muyezo wamagalavu osagwira moto ndi kutentha
TS EN 374 Zofunikira pakukana kwamankhwala kulowa kwa magolovesi oteteza
TS EN 511 Miyezo yoyang'anira zamagolovu ozizira komanso otsika osagwirizana ndi kutentha
TS EN 455 Magolovesi odzitchinjiriza pakukhudzidwa ndi chitetezo chodulidwa
Magolovesi otetezakuyendera njira
Pofuna kuteteza chitetezo cha ogula ndikupewa kutayika kwa ogulitsa chifukwa chokumbukira chifukwa cha zovuta zamtundu wazinthu, magolovesi onse oteteza omwe amatumizidwa kumayiko a EU akuyenera kuchita izi:
1. Kuyesa kwamakina pa malo
EN388:2016 Kufotokozera kwa Chizindikiro

Mayeso odulira a TDM amagwiritsa ntchito tsamba kuti adule zida za kanjedza zamagolovu pafupipafupi. Imayesa kutalika koyenda kwa tsamba pamene imadula chitsanzo pansi pa katundu wosiyana. Amagwiritsa ntchito masamu olondola kuti awerengere (otsetsereka) kuti apeze kuchuluka kwa mphamvu zomwe zimayenera kugwiritsidwa ntchito kuti tsambalo liziyenda 20mm. Dulani chitsanzocho.
Mayesowa ndi chinthu chatsopano mu EN388:2016 version. Zotsatira zake zimawonetsedwa ngati AF, ndipo F ndiye mulingo wapamwamba kwambiri. Poyerekeza ndi EN 388: 2003 mayeso a coupe, mayeso a TDM angapereke zolondola kwambiri zogwirira ntchito zogwirira ntchito.
5.6 Kukana kwamphamvu (EN 13594)
Chikhalidwe chachisanu ndi chimodzi chikuyimira chitetezo champhamvu, chomwe ndi kuyesa kosankha. Ngati magolovesi ayesedwa kuti atetezedwe, chidziwitsochi chimaperekedwa ndi chilembo P monga chizindikiro chachisanu ndi chimodzi komanso chomaliza. Popanda P, magolovesi alibe chitetezo champhamvu.
2. Kuyang'anira maonekedweza magolovesi oteteza
-Dzina la wopanga
- Magolovesi ndi makulidwe
- Chizindikiro cha CE
- Chithunzi cha EN standard logo
Zolemba izi ziyenera kukhala zomveka nthawi yonse ya moyo wa magolovesi
3. Magolovesi otetezakuyendera phukusi
- Dzina ndi adilesi ya wopanga kapena woimira
- Magolovesi ndi makulidwe
- Chizindikiro cha CE
- Ndi gawo lomwe mukufuna kugwiritsa ntchito / kagwiritsidwe ntchito, mwachitsanzo "pachiwopsezo chochepa chokha"
- Ngati magolovesi amangoteteza kudera linalake la dzanja, izi ziyenera kunenedwa, mwachitsanzo, "chitetezo cha kanjedza chokha"
4. Magolovesi otetezera amabwera ndi malangizo kapena mabuku ogwiritsira ntchito
- Dzina ndi adilesi ya wopanga kapena woimira
- Dzina la glove
- Mulingo wopezeka
- Chizindikiro cha CE
- Malangizo osamalira ndi kusunga
- Malangizo ndi malire ogwiritsira ntchito
- Mndandanda wa zinthu za allergenic mu magolovesi
- Mndandanda wazinthu zonse zomwe zili m'magolovesi omwe akupezeka mukafunsidwa
- Dzina ndi adilesi ya bungwe lopereka ziphaso lomwe lidatsimikizira malondawo
- Miyezo yoyambira
5. Zofunikira zopanda vutoza magolovesi oteteza
- Magolovesi ayenera kupereka chitetezo chokwanira;
- Ngati pali seams pa magolovesi, ntchito ya magolovesi sayenera kuchepetsedwa;
- pH iyenera kukhala pakati pa 3.5 ndi 9.5;
- Zomwe zili mu Chromium (VI) ziyenera kukhala zochepa kuposa mtengo wodziwikiratu (<3ppm);
- Magolovesi achilengedwe a mphira amayenera kuyesedwa pa mapuloteni ochotsedwa kuti atsimikizire kuti samayambitsa ziwengo mwa wovala;
- Ngati malangizo oyeretsera aperekedwa, milingo ya magwiridwe antchito sayenera kuchepetsedwa ngakhale zitatha kuchuluka kwa kutsuka.
Muyezo wa EN 388: 2016 ukhoza kuthandiza ogwira ntchito kudziwa kuti ndi magolovesi ati omwe ali ndi mulingo woyenera wachitetezo ku zoopsa zamakina pamalo ogwirira ntchito. Mwachitsanzo, ogwira ntchito yomanga nthawi zambiri amakumana ndi chiopsezo cha kuwonongeka ndi kung'ambika ndipo amafunika kusankha magolovesi omwe ali ndi kukana kwapamwamba kwambiri, pamene ogwira ntchito zachitsulo ayenera kudziteteza kuti asawononge kuvulala kwa zida zodula kapena zokopa zazitsulo zakuthwa, zomwe zimafuna kusankha magolovesi ndi mlingo wapamwamba wa kukana odulidwa. Magolovesi.
