Izimplications Zokugcina Ubuhle, Ubucayi, kanye Nezimpendulo

Ukukhupha Kwesilica Dust: Kungani Ukuthatha Kwesikhali Kufuna Ukusebenzisa Okwanele Kwamaphoyinti Okubulawa Komhlaba Kwaye Amasistimu Okukhupha

Kodwa abasebenzi bafana ngokusebenzisa ukuchitha kwe-diamond ngokosha, bakhulula kubona i-respirable crystalline silica (RCS), okuyisilika esikhululwe ngokuphambuka kwezinye izinhlanganiso zezempilo, futhi yisilika esibhekiswe njengesilika se-Group 1 sokuqhubeka kwemithombo yezifo ngokwesibonelo se-IARC. I-Occupational Safety and Health Administration (OSHA) yasikhipha ngo-2016 ukuthi abasebenzi asifanele ukubekwa phakathi kwe-RCS engaphezu kwe-micrograms e-50 ngumetro ocubi weyirili emva kwezinsuku zokusebenza zabo zokugcina amahour e-8. Kodwa lapho kukhona indlela yokufuna: uma akukho imithombo yezimpilo yezindawo zokusebenza ezihle ekuseni, ukuchitha ngokosha kwezindawo zokusebenza kungabangela ukuthi i-RCS ibe phezulu kwe-micrograms e-500 ngumetro ocubi weyirili — lokhu kuyisishiyane esikhulu kwezinkambo zokuziphatha ngokuphelele. Lokhu kubangela izifo ezinkulu ezifana no-silicosis, okuyizifo ezenza ukuthi abasebenzi abaningi be-Amerika bafaye ngasinye isinye ngonyaka ngokusho kweziripholi ze-CDC ezenziwe ngo-2022. Amakhampani futhi abhekwa ngamaphawu amakhulu uma bafundwa ukuthi bavule izimthombo zokuziphatha, nokuthi amaphawu angaba amakhulu kakhulu kakhulu kwezinkambo e-156,259 ngalokho okwenza ngokuvulekile ngokusho kwezimthombo ze-OSHA ezenziwe uphendula ngo-2024. Ukuze bavikele abasebenzi ngokuphelele, abaphathisi badinga ukunikeza abasebenzi amaphetheli ase-N95 noma amaphetheli ase-N100 angcono kakhulu, ukufaka amasistimu e-vacuum ezenziwe ngamafiltara ase-HEPA okukhulula izinye izinto ezincinci kwe-microns e-0.3 ngokuphambuka kwe-99.97%, futhi uma kungenzeka ukufaka izindawo zokuchitha ezingcwele. Umqondo wokugcina ophuma ku-Journal of Safety Research ngo-2023 wabonisa okuthi kuyisibonelo esingazange siyisibonelo sokuthi izindawo zokusebenza ezingaqondi izimthombo zokuziphatha zokusebenza zibhekwa ngokuphambuka kwe-73% uma ziqhathaniswa nezifundo zokusebenza zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubhala izifundo zokubh......

Ubukhulu Bokuphepha Kwemithambo Nezinkinga Zokufika Kwezinye Izingxenye Emazulwini

Ukusebenzisa imithambo yokugcutsha engaphansi kwamandla emanzi ibuyela kubona izinkinga zokuphepha kakhulu ngokuvamile ngemibono emibili. Okokuqala kukho ububi bokufa ngamandla ekhona uma manzi ayisiphakade kulezi zixhobo zokugcina ezinamandla angaphezu kwe-120 volts. Okwesibili kukho izinkinga zokuhlupha nokufallwa okuthiwa ngamandla amanzi akhona kuzo zonke izindawo ngokungafanele. Ngokwesayensi esizayo sika-NFPA, ngokwesikhathi sesiphakade, umbhalo wama-42% wezifo zokuphepha ngamandla kumsebenzi wokwakha kuthiwa ngokuxhukuma kwezinye zezinto zomnandi. Ngakolunye uhlangothi, iBureau of Labor Statistics isibonisa ukuthi izindawo ezingahluphi kakhulu ziyathola ama-18% wezifallwa kubantu abasebenza ngamandla amanzi. Ukuphepha kwenyathelo, abasebenzi bokwakha kufanele banezindlela eziningi zokuphepha. Izikhululo kufanele zibe nezinkampani zokuphepha zokuphinda (GFCI) ozokuphinda ngaphansi kwe-5 milliseconds. Abasebenzi kufanele banezincwadi zokuphepha ezihlakaniphile zokuphinda ngokulinganisa kwe-ASTM F2913. Ukuseta izimpande zokuphepha kufanele kusobala ukuthi amanzi asilale kuzo zonke izindawo, futhi izixhobo kufanele zihlanganiswe ngokuphinda kwe-dielectric ngisho noma yisikhathi esingaphezu kwezinsuku zonke. Ukudibanisa lezi zonke ziyabeka izinkinga zokuphepha kwenyathelo ngokuphakeme kwe-31%, futhi yasivumela izindlela zokuphepha zokuphatha izinto ezihlukaniswe kwi-ANSI/ISEA 121-2018.
