Magnet Safety:

Cov hlau nplaum tsis tshua muaj hauv ntiaj teb lossis cov tshuab sib nqus muaj zog heev, yog li cov kev ceev faj txog kev nyab xeeb hauv qab no yuav tsum raug coj los rau txhua tus neeg ua haujlwm uas yuav siv, tuav, lossis ua haujlwm kom tsis txhob raug mob lossis puas rau cov hlau nplaum.

Xyuas kom tseeb tias cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb yog tswj tau thaum lawv sib cuag nrog ib leeg lossis cov khoom ferromagnetic.Nws yog ib qho tseem ceeb uas yuav tsum hnav tsom iav kev nyab xeeb thiab lwm yam khoom tiv thaiv tsim nyog thaum tuav cov hlau nplaum loj.Hnav hnab looj tes los tiv thaiv ib txhais tes kuj pom zoo.

Khaws cov hlau ferromagnetic kom deb ntawm qhov chaw ua haujlwm.Ua tib zoo mloog thaum ua haujlwm nrog cov hlau nplaum.Tsis txhob ua haujlwm nrog cov hlau nplaum hlau nplaum yog tias koj nyob hauv qab cawv, tshuaj, lossis tshuaj tswj.

Cov cuab yeej hluav taws xob thiab cov khoom siv hluav taws xob muaj peev xwm hloov pauv tau lossis raug puas tsuaj los ntawm lub zog sib nqus.Nco ntsoov khaws cov hlau nplaum hlau nplaum kom muaj kev nyab xeeb deb ntawm cov khoom siv hluav taws xob rhiab heev.Kev ceev faj tshwj xeeb yuav tsum tau siv yog tias ib tus neeg hnav lub tshuab pacemaker, vim tias cov hlau nplaum muaj zog tuaj yeem ua rau cov khoom siv hluav taws xob puas tsuaj hauv cov pacemakers.

Tsis txhob nqos cov hlau nplaum los yog tso cov hlau nplaum ze ze ntawm cov menyuam yaus lossis cov neeg laus uas muaj kev puas hlwb.Yog tias cov hlau nplaum raug nqos, nrog kws kho mob tam sim ntawd thiab/lossis nrhiav kev kho mob tam sim ntawd.

Cov hlau nplaum tsis tshua muaj hauv ntiaj teb tuaj yeem tsim cov nplaim taws los ntawm kev sib cuag hauv kev tuav, tshwj xeeb tshaj yog thaum tso cai rau cuam tshuam ua ke.Tsis txhob kov cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb nyob rau hauv cov huab cua tawg vim tias qhov ci ntsa iab tuaj yeem cuam tshuam qhov cua.

Tsis tshua muaj hmoov av yog combustible;spontaneous combustion tuaj yeem tshwm sim thaum cov hmoov qhuav.Yog tias sib tsoo, ib txwm ntub cov hlau nplaum sib nqus kom tsis txhob muaj kev sib tsoo ntawm qhov sib tsoo swarf.Tsis txhob qhuav grind.Nco ntsoov kom muaj qhov cua txaus thaum sib tsoo hlau nplaum.Tsis txhob sim tshuab cov hlau nplaum siv cov cuab yeej siv, vim qhov no tuaj yeem tsim chipping thiab tawg.Ib txwm hnav tsom iav kev nyab xeeb.

Nco ntsoov khaws cov hmoov av tsawg lossis sib tsoo swarf hauv cov ntim dej los yog hermetically kaw inert cua kom tsis txhob muaj kev sib tsoo.

Nco ntsoov pov tseg cov hmoov av tsawg nrog kev saib xyuas.Tsis txhob raug hluav taws kub.Kev pov tseg cov hlau nplaum hlau nplaum yuav tsum tau ua kom tsis txhob raug mob thaum tuav.
