Lo mbhalo uhlose ukunciphisa ukuvulwa ngephutha kwamavalvu okwenziwa ngesandla ezinhlelweni zesiqandisi se-ammonia.
Njengengxenye yohlelo lokulawula ugesi, i-International Ammonia Refrigeration Institute (IIAR) ikhiphe uchungechunge lwezincomo zokuvimbela ukuvulwa ngephutha kwamavalvu okwenziwa ngesandla ezimisweni zesiqandisi se-ammonia (R717).
Inguqulo yokuqala yesiphakamiso-Iziqondiso zokuthuthukisa izinhlelo zokulawula amandla ama-valve okwenziwa ngesandla ku-ammonia refrigeration systems-amalungu e-IIAR angayithenga ngamaRandi angu-150, futhi abangewona amalungu bangayithenga ngama-dollar angu-300.
Ukulawulwa kwe-valve eyenziwa ngesandla kungokwamandla ayingozi, okuvame ukubizwa ngokuthi inqubo yokukhiya/i-tagout (LOTO). Ngokusho kwewebhusayithi ye-University of Iowa Environmental Health and Safety, lokhu kungavikela izisebenzi ukuthi zingalimali noma zibulawe ukwenziwa kusebenze ngengozi noma ukukhishwa kwamandla agciniwe lapho kugcinwa futhi kulungiswa imishini, izinqubo, nezinhlelo.
Amandla ayingozi angaba ugesi, amanzi, umoya, imishini, amakhemikhali, ashisayo, noma eminye imithombo. "Ukulandela izinqubo nezinqubo ezifanele ze-LOTO kungavikela abasebenzi ekukhishweni kwamandla ayingozi," kunezela iwebhusayithi ye-University of Iowa.
Kusukela i-US Occupational Health and Safety Administration (OSHA) yenza umthetho wokulawula amandla ayingozi (ukukhiya/uhlu) ngo-1989, izimboni eziningi zenze izinhlelo zokulawula amandla e-LOTO. Kodwa lezi ngokuvamile zigxile emandleni ayingozi kagesi nawemishini; ngokusho kwe-IIAR, imboni ye-HVAC&R ayinakho ukucaciseleka ekuvulekeni ngephutha kwamavalvu okwenziwa ngesandla, okuyimbangela yokuvuza okuningi kwe-ammonia.
Umhlahlandlela omusha uhlose “ukugcwalisa igebe lemboni” futhi unikeze abanikazi nabasebenzisi bamavalvu enziwe ngesandla engu-R717 ngezeluleko ezingcono kakhulu zokuthi zisetshenziswa kanjani izinhlelo zokulawula amandla.
