S1 thiab S3 khau kev nyab xeeb yog dab tsi?
Cov khau kev nyab xeeb yog ib qho tseem ceeb ntawm cov cuab yeej tiv thaiv tus kheej (PPE) rau cov neeg ua haujlwm hauv kev lag luam uas muaj feem cuam tshuam rau lawv txhais taw. Lawv tau tsim tshwj xeeb los tiv thaiv ob txhais taw los ntawm ntau yam kev pheej hmoo xws li cov khoom ntog, cov npoo ntse, cov tshuab hnyav, hluav taws xob muaj kev phom sij, thiab cov khoom ntog. Kev nyab xeeb khau tuaj nyob rau hauv ntau hom thiab kev faib tawm raws li qib kev tiv thaiv lawv muab. Ob qhov kev faib tawm yog S1 thiab S3 kev nyab xeeb khau. Hauv tsab xov xwm no, peb yuav nkag siab tob rau hauv cov kev faib tawm no thiab nkag siab txog lawv cov yam ntxwv, txiaj ntsig, thiab kev pom zoo siv.
S1 Safety khau
S1 khau kev nyab xeeb, tseem hu ua khau kev nyab xeeb yooj yim, yog tsim los muab kev tiv thaiv yam tsawg kawg nkaus uas xav tau los ntawm kev lag luam feem ntau. Lawv tsim nyog rau ib puag ncig uas muaj kev pheej hmoo tsawg ntawm kev raug mob lossis kev phom sij tsis tseem ceeb. Cia peb saib ze dua ntawm cov yam ntxwv ntawm S1 khau kev nyab xeeb:
1. ntiv taw tiv thaiv: S1 kev nyab xeeb khau muaj lub hau tiv thaiv ua los ntawm cov hlau lossis cov khoom sib xyaw kom tiv thaiv cov ntiv taw los ntawm kev cuam tshuam thiab kev raug mob compression. Lub kaus mom tuaj yeem tiv taus qhov cuam tshuam ntawm 200 joules thiab muaj qhov compression tsis kam ntawm 15, 000 newtons.
2. Kaw Heel Area: S1 kev nyab xeeb khau muaj qhov chaw kaw pob taws, uas muab kev txhawb nqa thiab kev tiv thaiv pob taws tiv thaiv kev cuam tshuam.
3. Antistatic Properties: Cov khau no muaj cov khoom tiv thaiv zoo li qub uas tiv thaiv kev tsim hluav taws xob zoo li qub thiab txo qhov kev pheej hmoo ntawm hluav taws xob tawm, uas tuaj yeem cuam tshuam cov nplaim taws.
4. Zog Absorption: S1 nkawm khau muaj kev poob siab-absorbing hauv cheeb tsam pob taws, txo qhov cuam tshuam ntawm ko taw thaum taug kev lossis khiav.
5. Slip Resistance: Lub outsole ntawm S1 kev nyab xeeb nkawm khau yog tsim los muab kev tiv thaiv zoo rau ntawm ntau qhov chaw, txo qhov kev pheej hmoo ntawm kev sib tsoo vim kev swb.
6. Dej Resistant: S1 khau kev nyab xeeb muaj qee qhov kev tiv thaiv dej, ua kom cov ko taw qhuav thiab xis nyob hauv qhov dej ntub lossis ntub dej. Txawm li cas los xij, lawv tsis yog dej tsis txaus.
Txawm hais tias muaj kev tiv thaiv theem pib, S1 khau kev nyab xeeb yuav tsis haum rau qee qhov chaw muaj kev pheej hmoo siab xws li chaw tsim kho lossis kev lag luam hnyav. Cia tam sim no tshawb xyuas S3 khau kev nyab xeeb, uas muab kev tiv thaiv qib siab dua.
S3 Safety khau
S3 khau kev nyab xeeb yog suav tias yog tus qauv siab dua hauv kev nyab xeeb khau. Lawv muab kev tiv thaiv zoo dua piv rau S1 nkawm khau kev nyab xeeb thiab tsim nyog rau ib puag ncig uas muaj kev phom sij ntau dua. Nov yog cov yam ntxwv ntawm S3 kev nyab xeeb khau:
1. Tag nrho cov nta ntawm S1 Safety khau: S3 kev nyab xeeb nkawm khau suav nrog tag nrho cov yam ntxwv ntawm S1 kev nyab xeeb khau, xws li kev tiv thaiv ntiv taw, qhov chaw kaw pob taws, cov khoom tiv thaiv zoo li qub, lub zog nqus, plam tsis kam, thiab dej tsis kam.
2. Nkag siab tsis kam: S3 kev nyab xeeb nkawm khau muaj qhov puncture-resistant midsole uas tiv thaiv ob txhais taw ntawm kev raug mob los ntawm cov khoom ntse, xws li rau tes lossis iav shards. Lub midsole feem ntau yog ua los ntawm cov khoom siv tau yooj yim xws li steel.
3. Waterproof: Tsis zoo li S1 nkawm khau kev nyab xeeb, S3 khau ruaj ntseg tsis muaj dej tsis txaus. Lawv muab kev tiv thaiv zoo dua tiv thaiv dej, tshuaj, thiab lwm yam kua, ua kom cov ko taw qhuav hauv qhov chaw ntub dej.
4. Tsis kam rau roj thiab roj: S3 kev nyab xeeb khau yog tsim los tiv thaiv kev nkag mus los ntawm cov roj thiab roj, txo cov kev pheej hmoo ntawm kev sib tsoo thiab kev sib tsoo hauv qhov chaw zoo li no.
5. Cleated Outsole: S3 kev nyab xeeb khau muaj ib qho cleated outsole uas muab kev zoo dua traction ntawm qhov chaw nplua, av nkos, lossis qhov chaw tsis sib xws, ua kom muaj kev ruaj ntseg thiab txo qhov kev pheej hmoo ntawm kev poob.
Xav txog cov yam ntxwv ntxiv, S3 kev nyab xeeb khau feem ntau pom zoo rau cov chaw ua haujlwm uas muaj kev pheej hmoo siab dua xws li chaw tsim kho, thaj chaw mining, roj refineries, tshuaj nroj tsuag, thiab cov lag luam zoo sib xws uas muaj kev pheej hmoo ntawm kev raug mob ko taw tseem ceeb.
Xaus
Hauv cov ntsiab lus, S1 thiab S3 nkawm khau kev nyab xeeb yog kev faib cov khau kev nyab xeeb siv nyob rau hauv qhov chaw ua haujlwm sib txawv raws li qib kev tiv thaiv yuav tsum tau ua. S1 khau kev nyab xeeb muab kev tiv thaiv yooj yim tiv thaiv kev phom sij, suav nrog kev tiv thaiv ntiv taw, cov khoom siv tiv thaiv zoo, plam tsis kam, thiab dej tsis kam. Ntawm qhov tod tes, S3 khau kev nyab xeeb muaj kev tiv thaiv qib siab, suav nrog tag nrho cov yam ntxwv ntawm S1 khau, nrog rau kev tiv thaiv kev tiv thaiv, dej tsis muaj dej, tiv thaiv roj thiab roj, thiab cleated outsoles kom zoo dua traction.
Nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khau kev nyab xeeb raws li cov xwm txheej tshwj xeeb uas muaj nyob hauv chaw ua haujlwm. Cov tswv ntiav haujlwm yuav tsum ua qhov kev ntsuam xyuas txaus ntshai los txiav txim siab txog qib kev tiv thaiv uas tsim nyog rau lawv cov neeg ua haujlwm. Kev muab cov neeg ua haujlwm nrog cov khau ruaj ntseg tsis yog tsuas yog ua kom lawv txoj kev noj qab haus huv xwb tab sis kuj txhawb kev nyab xeeb thiab ua haujlwm zoo.
