Kusukela izinga le-ANSI Z358.1 lale mpahla yokugezwa yesimo esiphuthumayo yaqalwa ngo-1981, kube nezibuyekezo ezinhlanu ezakamuva ngo-2014. Ekubuyekezweni ngakunye, le mpahla yokuwasha yenziwa iphephe kubasebenzi nasezindaweni zamanje zasemsebenzini.Ku-FAQ engezansi, uzothola izimpendulo ezivame ukubuzwa mayelana nalesi sixhobo esiphuthumayo.Sithemba ukuthi lokhu kuwusizo kuwe kanye nenhlangano yakho.
IZIDINGO ze-OSHA
Ubani onquma ukuthi isikhungo sidinga nini isiteshi sokugeza amehlo esiphuthumayo?
I-Occupational Safety and Health Association (OSHA) yi-ejensi elawulayo ecacisa ukuthi lezi zisetshenziswa eziphuthumayo zidingeka kuphi futhi nini futhi i-OSHA incike ku-American National Standards Institute (ANSI) ukuze ithuthukise amazinga ukuze ucacise izidingo zokusetshenziswa nokusebenza.I-ANSI ithuthukise izinga le-ANSI Z 358.1 ngale njongo.
Yiziphi izindlela ezisetshenziswa yi-OSHA ukwenza lesi sinqumo?
I-OSHA ithi noma nini lapho amehlo noma umzimba womuntu ungachayeka ezintweni ezonakalisayo, indawo izohlinzeka ngemishini yokukhukhula nokucwiliswa ngokushesha endaweni yokusebenza ukuze isetshenziswe ngokushesha.
Iluphi uhlobo lwempahla oluthathwa njengento edlayo?
Ikhemikhali izobhekwa njengegqwala uma ibhubhisa noma ishintsha (ngokungenakuhlehliswa) ukwakheka kwezicubu zomuntu endaweni okuxhumene kuyo ngemva kokuchayeka isikhathi esithile ngemva kwalokho.
Wazi kanjani uma into ethile endaweni yokusebenza igqwala?
Izinto ezonakalisayo zikhona ezindaweni eziningi zokusebenza zizodwa noma ziqukethwe kwezinye izinto.Kungumqondo omuhle ukubhekisa emashidini e-MSDS azo zonke izinto ezitholakalayo emsebenzini.
AMAZINGA ANSI
Kunesikhathi esingakanani izindinganiso ze-ANSI zalesi sisetshenziswa zitholakala endaweni yokusebenza yezimboni?
Izinga le-ANSI Z 358.1 lashicilelwa okokuqala ngo-1981 labuye labuyekezwa ngo-1990, 1998, 2004, 2009 nango-2014.
Ingabe izinga le-ANSI Z 358.1 lisebenza kuphela eziteshini zokugeza amehlo?
Cha, izinga lisebenza nasezishaweni zesimo esiphuthumayo namathuluzi okugeza amehlo/ubuso.
IZIDINGO ZOKUSHISA KANYE NEZILINGANISO
Yiziphi izidingo zokugeza eziteshini zokugeza amehlo?
Ukugeza kwamehlo okuphathekayo okuphathekayo nokunamapayipi kokubili kudinga ukugezwa kwamalitha angu-0.4 (GPM) ngomzuzu, okungamalitha angu-1.5, imizuzu engu-15 egcwele enamavalvu asebenza ngomzuzwana ongu-1 noma ngaphansi futhi ahlale evulekile ukuze kushiye izandla zikhululekile.Iyunithi yamapayipi kufanele inikeze uketshezi olushaywayo ngamaphawundi angama-30 ngeyintshi yesikwele (PSI) ngokunikezwa kwamanzi okungaphazamiseki.
Ingabe kunezidingo ezihlukene zokushaywa kwesiteshi sokugeza amehlo/ubuso?
Isiteshi sokugeza amehlo/ubuso sidinga ukugezwa ngamalitha angu-3 (GPM) ngomzuzu, okungamalitha ayi-11.4, imizuzu eyi-15 egcwele Kufanele kube namakhanda amakhulu okugeza amehlo angakwazi ukuvala kokubili amehlo nobuso noma isifutho sobuso esingasetshenziswa uma evamile. amakhanda okugeza amehlo osayizi afakwe kuyunithi.Kukhona futhi amayunithi anezifutho ezihlukene zamehlo nezifutho ezihlukene zobuso.Indawo nokugcinwa kwezinto zokugeza amehlo/ubuso kuyafana neziteshi zokugeza amehlo.Ukuma kuyafana nesiteshi sokugeza amehlo.
Yiziphi izimfuneko zokugeza izishawa eziphuthumayo?
Amashawa aphuthumayo axhunywe unomphela emthonjeni wamanzi aphuzwayo endaweni kufanele abe nesilinganiso sokugeleza esingamamalitha angama-20 (GPM) ngomzuzu, okungamalitha angama-75.7, namaphawundi angu-30 (PSI) ngeyintshi yesikwele ngayinye yamanzi angaphazanyiswa. .Amavalvu kufanele asebenze kusekhondi elingu-1 noma ngaphansi futhi kufanele ahlale evulekile ukuze ashiye izandla zikhululekile.Amavalvu akula mayunithi akufanele avale aze avalwe umsebenzisi.
Ingabe zikhona izidingo ezikhethekile zama-Combination Showers aqukethe ingxenye yokugeza amehlo neshawa?
Ingxenye ye-eyewash kanye nengxenye yeshawa kumele ngayinye ibe nesitifiketi ngasinye.Uma iyunithi ivuliwe, ayikho ingxenye engalahlekelwa umfutho wamanzi ngenxa yokuthi enye ingxenye yenziwa isebenze ngesikhathi esifanayo.
Ingabe uketshezi olushaywayo kufanele luphakame kangakanani kusukela ekhanda lesiteshi sokugeza amehlo ukuze kuhlanzeke ngokuphephile amehlo?
Uketshezi olushaywayo kufanele lube phezulu ngokwanele ukuvumela umsebenzisi ukuthi akwazi ukubamba amehlo evulekile ngenkathi eshayela.Kufanele imboze izindawo eziphakathi kwemigqa yangaphakathi nangaphandle yegeji ngesikhathi esingaphansi kwamayintshi ayisishiyagalombili (8).
Uketshezi olushaywayo kufanele luphume ngokushesha kangakanani emakhanda?
Ukugeleza okuya phezulu kufanele kulawulwe ngesilinganiso esincane sokugeleza ngesivinini esiphansi ukuze kuqinisekiswe ukuthi amehlo omuntu ohlukunyezwayo awaphinde alinyazwe ukugeleza koketshezi olushaywayo.
IZIDINGO ZOKUSHISA
Iyini imfuneko yezinga lokushisa loketshezi olushaywayo esiteshini sokugeza amehlo ngokuya nge-ANSI/ISEA Z 358.1 2014?
Izinga lokushisa lamanzi oketshezi olushaywayo kufanele libe pholile okusho ukuthi ndawana thize phakathi kuka-60º kanye no-100ºF.(16º-38º C).Ukugcina uketshezi olushaywayo phakathi kwalawa mazinga okushisa amabili kuzokhuthaza isisebenzi esilimele ukuthi sihlale ngaphakathi kwemihlahlandlela ye-ANSI Z 358.1 2014 imizuzu eyi-15 egcwele yokushaywa okuzosiza ukuvimbela ukulimala okwengeziwe kweso nokuvimbela ukumuncwa okwengeziwe. amakhemikhali.
Izinga lokushisa lingalawulwa kanjani ukuze lihlale liphakathi kuka-60º kanye no-100ºF endaweni yokugeza amehlo ephuthumayo noma izihlambi ukuze kuthobelane nezinga elibuyekeziwe?
Uma uketshezi olushaywayo kunqunywa ukuthi alukho phakathi kuka-60º kanye no-100º, amavalvu okuxuba e-thermostatic angafakwa ukuze kuqinisekiswe izinga lokushisa elilinganayo le-eyewash noma ishawa.Kukhona futhi amayunithi ama-turnkey atholakalayo lapho amanzi ashisayo anganikezelwa khona kuyunithi ethile ethile.Ezindaweni ezinkulu ezinokugeza amehlo namashawa amaningi, kunezinhlelo eziyinkimbinkimbi ezingafakwa ukuze kugcinwe izinga lokushisa phakathi kuka-60º kanye no-100ºF kuwo wonke amayunithi endaweni.
