Pyrophoric Hazards
HCS txhais rau a pyrophoric Cov tshuaj yog "ib yam tshuaj uas yuav ignite nyob rau hauv cov huab cua ntawm ib tug kub ntawm 130º F (54.4ºC) los yog hauv qab no." Hmoov zoo, tsuas muaj ob peb yam tshuaj uas muaj peev xwm ntes tau hluav taws tsis muaj ignition qhov chaw thaum raug huab cua.
Tsuas yog li ntawd, dab tsi yog qhov phom sij pyrophoric?
Pyrophoric cov ntaub ntawv yog cov khoom uas ignite instantly thaum raug oxygen. Lawv kuj tuaj yeem ua dej-reactive, qhov twg cov cua sov thiab hydrogen (cov pa hluav taws xob) raug tsim. Lwm yam phom sij muaj xws li corrosivity, teratogenicity, thiab organic peroxide.
Ib sab saum toj no, 5 hom kev phom sij yog dab tsi? Hom kev phom sij hauv chaw ua haujlwm suav nrog tshuaj , ergonomic, lub cev, kev xav thiab kev ua haujlwm dav dav. Hmoov zoo, muaj txoj hauv kev los txo cov kev pheej hmoo los ntawm cov kev phom sij xws li los ntawm kev npaj, kev cob qhia thiab kev saib xyuas.
Qhov thib ob, 3 kev faib tawm ntawm kev phom sij yog dab tsi?
Cov xwm txheej zoo li no tau muab faib ua peb pawg: lom neeg, tshuaj lom neeg thiab lub cev. Cov tshuaj lom neeg muaj kev phom sij kab mob kab mob los yog kab mob (piv txwv li, salmonella, kab mob siab A thiab trichinella). Kev phom sij tshuaj lom neeg muaj xws li cov khoom sib txuas uas tuaj yeem ua rau muaj mob lossis raug mob vim raug cuam tshuam tam sim lossis mus ntev.
Plaub hom kev phom sij ntawm lub cev yog dab tsi?
Lawv tuaj yeem raug cais raws li hom ntawm kev ua haujlwm phom sij los yog ib puag ncig phom sij . Kev phom sij rau lub cev suav nrog ergonomic phom sij , hluav taws xob, kub thiab txias kev ntxhov siab, kev co phom sij , thiab suab phom sij . Engineering tswj feem ntau yog siv los txo qis kev phom sij rau lub cev.

Puas yog tag nrho cov tshuaj nyob rau hauv ib chav kuaj pom tias muaj kev phom sij?
Tag nrho cov tshuaj nyob rau hauv lub chav kuaj yuav tsum raug xam tias yog txaus ntshai. 24. Muab tag nrho cov tshuaj uas tsis tau siv rov qab mus rau lawv cov ntim qub. Kev ua haujlwm hauv chav kuaj tuaj yeem pib tam sim ntawd thaum nkag mus rau hauv chav kuaj txawm tias tus kws qhia tseem tsis tau tuaj
Dab tsi yog ob hom kev phom sij uas cuam tshuam rau tib neeg kev noj qab haus huv?
Muaj ntau ntau hom tshuaj lom neeg, xws li neurotoxins, tshuaj tiv thaiv kab mob, tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob, co toxins, asthmagens, pneumoconiotic agents, thiab sensitizers. Cov kev phom sij no tuaj yeem ua rau muaj kev pheej hmoo ntawm lub cev thiab / lossis kev noj qab haus huv
Lub koom haum twg yog lub luag haujlwm rau US cov cai tswj kev phom sij?
Cov khoom siv phom sij raug txhais thiab tswj hwm hauv Tebchaws Meskas feem ntau los ntawm cov cai thiab cov cai tswj hwm los ntawm US Environmental Protection Agency (EPA), US Occupational Safety and Health Administration (OSHA), US Department of Transportation (DOT), thiab US Nuclear Regulatory Commission (NRC
