Tsekani tag out-Safety Operation Guide

Chikalatachi cholinga chake ndi kuchepetsa kutsegulidwa mwangozi kwa mavavu apamanja mu kachitidwe ka firiji ya ammonia.

Monga gawo la dongosolo lowongolera mphamvu, bungwe la International Ammonia Refrigeration Institute (IIAR) lidapereka malingaliro angapo kuti aletse kutsegulidwa mwangozi kwa ma valve opangira ma firiji ammonia (R717).

Mtundu woyamba wa malingaliro-Malangizo opangira mapulani owongolera mphamvu zamavavu apamanja mu ammonia refrigeration system-mamembala a IIAR amatha kugula $150, ndipo omwe si mamembala amatha kugula $300.

Kuwongolera kwa valavu yamanja kumayang'anira mphamvu yowopsa, yomwe nthawi zambiri imatchedwa njira yotsekera / tagout (LOTO).Malinga ndi tsamba la University of Iowa Environmental Health and Safety, izi zitha kuteteza ogwira ntchito kuti asavulale kapena kuphedwa mwangozi mwangozi kapena kutulutsa mphamvu zosungidwa posunga ndi kukonza makina, njira, ndi machitidwe.

Mphamvu zowopsa zimatha kukhala magetsi, ma hydraulic, pneumatic, makina, mankhwala, matenthedwe, kapena zinthu zina."Kutsatira machitidwe ndi njira zoyenera za LOTO kungateteze ogwira ntchito kuti asatulutse mphamvu zowonongeka," webusaiti ya University of Iowa ikuwonjezera.

Kuyambira pomwe bungwe la US Occupational Health and Safety Administration (OSHA) lidakhazikitsa malamulo owongolera mphamvu (lock/list) mu 1989, mafakitale ambiri akhazikitsa mapulogalamu owongolera mphamvu a LOTO.Koma izi nthawi zambiri zimakhazikika pamagetsi owopsa ndi mphamvu zamakina;malinga ndi IIAR, makampani a HVAC & R samamveka bwino pakutsegula mwangozi ma valve amanja, zomwe zimapangitsa kuti ammonia achuluke.

Buku latsopanoli likufuna "kudzaza kusiyana kwa makampani" ndikupatsa eni ake ndi ogwiritsira ntchito ma valve a manual R717 omwe ali ndi malangizo abwino a momwe angagwiritsire ntchito ndondomeko zoyendetsera mphamvu.
