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 kungokokulawula amandla ayingozi, ngokuvamile okubizwa ngokuthi inqubo yokukhiya/i-tagout (LOTO).Ngokusho kwewebhusayithi ye-University of Iowa Environmental Health and Safety, lokhu kungavikela abasebenzi ekulimaleni noma ukubulawa ngokuvula ngengozi noma ukukhululwa kwamandla agciniwe lapho kugcinwa futhi kulungiswa imishini, izinqubo, nezinhlelo.
Amandla ayingozi angaba ugesi, i-hydraulic, i-pneumatic, mechanical, chemical, thermal, 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 kanye nabasebenzisi bamavalvu enziwe ngesandla engu-R717 ngezeluleko ezingcono kakhulu zokuthi zisetshenziswa kanjani izinhlelo zokulawula amandla.
