Ukususela ekubeni umgangatho we-ANSI Z358.1 wale zixhobo zokugungxula ezingxamisekileyo zaqalwa ngo-1981, kukho ukuhlaziywa okuhlanu kunye ne-2014 yakutshanje.Kule FAQ ingezantsi, uya kufumana iimpendulo ezidla ngokubuzwa malunga nesi sixhobo sikaxakeka.Siyathemba ukuba oku kuluncedo kuwe nakumbutho wakho.
IIMFUNO ze-OSHA
Ngubani omisela xa iziko lifuna isikhululo sokuhlamba amehlo ngexesha likaxakeka?
I-Occupational Safety and Health Association (OSHA) yi-arhente elawulayo echaza apho kwaye nini esi sixhobo esiphuthumayo sifunekayo kwaye i-OSHA ixhomekeke kwi-American National Standards Institute (ANSI) ukuphuhlisa imigangatho yokucacisa iimfuno zokusetyenziswa kunye nokusebenza.I-ANSI iphuhlise umgangatho we-ANSI Z 358.1 kule njongo.
Zeziphi iindlela ezisetyenziswa yi-OSHA ukwenza olu miselo?
I-OSHA ithi nanini na xa amehlo okanye umzimba womntu unokuvezwa kwizinto ezitshabalalisayo, ngoko indawo iya kubonelela ngesixhobo sokugungxulwa nokuthotywa ngokukhawuleza kwindawo yokusebenza ukuze isetyenziswe ngokukhawuleza.
Loluphi uhlobo lwemathiriyeli egqalwa njengento edlayo?
Ikhemikhali iya kuthathwa njengento edlekayo ukuba iyonakalisa okanye itshintsha (ngokungenakujikwa) ulwakhiwo lwethishu yomntu kwindawo ekudityanwa kuyo emva kokuba sesichengeni sexesha elithile emva koko.
Wazi njani ukuba into ethile emsebenzini idlakadlaka?
Izinto ezonakalisayo zikhona kwiindawo ezininzi zokusebenza nokuba zizodwa okanye ziqulethwe kwezinye izinto.Kungumbono omhle ukubhekisa kumaphepha e-MSDS azo zonke izinto zokufunda ekukho ukutyhileka kuzo emsebenzini.
IMIGANGATHO YE-ANSI
Kude kube nini imigangatho ye-ANSI yesi sixhobo ikhona kwindawo yokusebenzela yoshishino?
Umgangatho we-ANSI Z 358.1 wapapashwa okokuqala kwi-1981 waza wahlaziywa ngo-1990, 1998, 2004, 2009 kunye no-2014.
Ngaba umgangatho we-ANSI Z 358.1 usebenza kuphela kwizitishi zamehlo?
Hayi, umgangatho uyasebenza nakwiishawa ezingxamisekileyo kunye nezixhobo zokuhlamba amehlo / ubuso.
UKUGUQUKA & IIMFUNO ZERETHA ZOPHUHLISO
Zeziphi iimfuno zokugungxulwa kwizitishi zokuhlambela amehlo?
I-gravity feeded ephathekayo kunye ne-plumbed eyewash zombini ifuna ukutshitshiswa kwe-0.4 (GPM) iilitha ngomzuzu, eyi-1.5 ilitha, yonke imizuzu eyi-15 epheleleyo kunye neevalvu ezisebenza kwi-1 yesibini okanye ngaphantsi kwaye zihlale zivulekile ukushiya izandla zikhululekile.Iyunithi yombhobho kufuneka ibonelele ngolwelo lokugungxulwa ngeeponti ezingama-30 nge-intshi nganye yesikwere (PSI) kunye nonikezelo lwamanzi olungaphazanyiswa.
Ngaba kukho iimfuno ezahlukeneyo zokugungxula kwindawo yokuhlamba amehlo/ebusweni?
Indawo yokuhlamba amehlo/ubuso ifuna ukugungxulwa kweelitha ezi-3 (GPM) ngomzuzu, eziyi-11.4 ilitha, kangangemizuzu eyi-15 egcweleyo Kufuneka kubekho iintloko ezinkulu zokuhlambela amehlo ezikwaziyo ukugquma omabini amehlo nobuso okanye isitshizi sobuso esinokusetyenziswa xa siqhelekile. Ubungakanani beentloko zokuhlambela amehlo zifakwe kwiyunithi.Kukwakho neeyunithi ezinezitshizi ezihlukeneyo zamehlo kunye nezitshizi ezihlukeneyo zobuso.Indawo kunye nokugcinwa kwezixhobo zokuhlambela amehlo / ubuso kuyafana nakwizikhululo zokuhlamba amehlo.Ukuma kuyafana nakwisikhululo sokuhlamba amehlo.
Zeziphi iimfuno zokugungxulwa kwiishawa zikaxakeka?
Iishawa ezingxamisekileyo ezidityaniswe ngokusisigxina kumthombo wamanzi okusela kwindawo kufuneka zibe nesantya sokuhamba kwe-20 (GPM) iilitha ngomzuzu, ezingama-75.7 iilitha, kunye ne-30 (PSI) yeepounds nge-intshi nganye yesikwere sobonelelo lwamanzi olungaphazanyiswa. .Iivalvu kufuneka zisebenze ngomzuzwana omnye okanye ngaphantsi kwaye kufuneka zihlale zivulekile ukushiya izandla zikhululekile.Iivalvu kwezi yunithi akufuneki zivale de zibe zivalwe ngumsebenzisi.
Ngaba kukho naziphi na iimfuno ezikhethekileyo zeeShawara eziDityanisiweyo eziqulathe indawo yokuhlamba amehlo kunye neshawari?
Icandelo lokuhlamba amehlo kunye necandelo leshawari kufuneka nganye ibe nesiqinisekiso somntu ngamnye.Xa iyunithi ivuliwe, akukho nxalenye inokuphulukana noxinzelelo lwamanzi ngenxa yokuba elinye icandelo lisebenza ngexesha elinye.
Kufuneka ulwelo lokugungxula luphakame kangakanani ukusuka entloko kwindawo yokuhlamba amehlo ukugungxula ngokukhuselekileyo amehlo?
Ulwelo olugungxulwayo kufuneka luphakame ngokwaneleyo ukuvumela umsebenzisi akwazi ukubamba amehlo evulekile ngelixa egungxula.Kufuneka igqume iindawo eziphakathi kwemigca yangaphakathi nangaphandle yegeyiji kwindawo ethile ngaphantsi kwee-intshi ezisibhozo (8).
Kufuneka ulwelo olugungxulwayo luphume ngokukhawuleza kangakanani entloko?
Ukuqukuqela okunyukayo kufuneka kulawulwe ngomlinganiselo omncinane wokuqukuqela ngesantya esiphantsi ukuze kuqinisekiswe ukuba amehlo exhoba awonakaliswa ngakumbi kukuhamba kolwelo olugungxulwayo.
IIMFUNO ZOBUCHUPHE
Ithini imfuneko yobushushu bolwelo olugungxulwayo kwisikhululo sokuhlamba amehlo ngokwe ANSI/ISEA Z 358.1 2014?
Ubushushu bamanzi kulwelo olugungxulwayo kufuneka lube pholileyo nto leyo ethetha ukuba phakathi kwe-60º kunye ne-100ºF.(16º-38ºC).Ukugcina ulwelo olugungxulwayo phakathi kwala maqondo obushushu mabini kuya kukhuthaza umsebenzi owenzakeleyo ukuba ahlale ngaphakathi kwezikhokelo ze-ANSI Z 358.1 2014 yonke imizuzu eyi-15 yokugungxulwa okuya kunceda ukuthintela ukwenzakala ngakumbi kwiliso (s) kunye nokuthintela ukufunxa ngakumbi. iikhemikhali.
Iqondo lobushushu lingalawuleka njani ukuze lihlale liphakathi kwe-60º kunye ne-100ºF kwindawo yokuhlamba amehlo kaxakeka okanye iishawari ukuze kuthotyelwe umgangatho ohlaziyiweyo?
Ukuba ulwelo lokugungxula luzimisele ukuba lungabikho phakathi kwe-60º kunye ne-100º, iivalvu zokuxuba ze-thermostatic zingafakelwa ukuqinisekisa ubushushu obuhambelanayo bokuhlamba kwamehlo okanye ishawa.Kukwakho neeyunithi ze-turnkey ezikhoyo apho amanzi ashushu anokunikezelwa ngokukodwa kwiyunithi ethile.Kwiindawo ezinkulu ezinokuhlamba amehlo kunye neshawari ezininzi, kukho iinkqubo ezinzima ngakumbi ezinokufakelwa ukugcina ubushushu phakathi kwe-60º kunye ne-100ºF kuzo zonke iiyunithi eziko.
