Olu xwebhu lujolise ekunciphiseni ukuvulwa ngengozi kweevalvu zesandla kwiinkqubo zesikhenkcisi se-ammonia.

Njengenxalenye yesicwangciso solawulo lwamandla, i-International Ammonia Refrigeration Institute (IIAR) ikhuphe uluhlu lwezindululo zokuthintela ukuvulwa ngengozi kweevalvu zezandla kwiinkqubo zesikhenkcisi ze-ammonia (R717).

Inguqulelo yokuqala yesiphakamiso-Izikhokelo zokuphuhlisa izicwangciso zolawulo lwamandla kwiivalvu zezandla kwiinkqubo zefriji ye-ammonia-amalungu e-IIAR angayithenga nge-$ 150, kunye nabangengawo amalungu angayithenga nge-300 yeedola.

Ulawulo lwesivalo semanuwali lololawulo lwamandla ayingozi, adla ngokubizwa ngokuba yinkqubo yokutshixa/i-tagout (LOTO).Ngokutsho kweYunivesithi yase-Iowa ye-Environmental Health and Safety website, oku kunokukhusela abasebenzi ukuba bangalimala okanye babulawe ngokusebenza ngengozi okanye ukukhululwa kwamandla agciniweyo xa kugcinwa kwaye kulungiswa oomatshini, iinkqubo kunye neenkqubo.

Amandla ayingozi anokuba ngumbane, ihydraulic, pneumatic, mechanical, chemical, thermal, okanye eminye imithombo."Ukulandela iindlela ezifanelekileyo zeLOTO kunye neenkqubo kunokukhusela abasebenzi ekukhutshweni kwamandla ayingozi," i-website yeYunivesithi yase-Iowa yongeza.

Ukususela ekubeni i-US Occupational Health and Safety Administration (OSHA) yenza umthetho wokulawula amandla anobungozi (ukutshixa / uludwe) kwi-1989, amashishini amaninzi aphumeze iinkqubo zokulawula amandla e-LOTO.Kodwa ezi zidla ngokujoliswa kumandla ombane kunye noomatshini ayingozi;ngokuka-IIAR, ishishini le-HVAC&R alinangcaciso ekuvulekeni ngengozi kweevalvu zesandla, nto leyo engunobangela wokuvuza okuninzi kwe-ammonia.

Isikhokelo esitsha sijolise “ekuzaleni umsantsa kushishino” kwaye sibonelele abanini kunye nabasebenzisi bemanuwali ye-R717 yeevalvu zemanuwali ngeengcebiso ezingcono zokusebenzisa izicwangciso zolawulo lwamandla.
