Kutseka chikwangwani chotuluka - Buku Lotsogolera Ntchito Yotetezeka

Chikalatachi cholinga chake ndi kuchepetsa kutseguka mwangozi kwa ma valve ogwiritsidwa ntchito ndi manja m'makina oziziritsira a ammonia.

Monga gawo la dongosolo lowongolera mphamvu, bungwe la International Ammonia Refrigeration Institute (IIAR) linapereka malangizo angapo kuti apewe kutsegulidwa mwangozi kwa ma valve ogwiritsira ntchito manja mu makina oziziritsira a ammonia (R717).

Mtundu woyamba wa lingaliroli - Malangizo opangira mapulani owongolera mphamvu zama valve opangidwa ndi manja mu makina oziziritsira a ammonia - mamembala a IIAR akhoza kugula pa $150, ndipo omwe si mamembala akhoza kugula pa $300.

Kulamulira kwa valavu yamanja ndi gawo la kulamulira mphamvu yoopsa, yomwe nthawi zambiri imatchedwa njira ya lockout/tagout (LOTO). Malinga ndi tsamba la University of Iowa Environmental Health and Safety, izi zitha kuteteza antchito kuti asavulale kapena kuphedwa ndi kuyatsa mwangozi kapena kutulutsa mphamvu yosungidwa pokonza ndi kukonza makina, njira, ndi machitidwe.

Mphamvu zoopsa zitha kukhala zamagetsi, zamadzimadzi, zampweya, zamakina, za mankhwala, za kutentha, kapena zina. "Kutsatira njira zoyenera za LOTO kungateteze antchito ku mphamvu zowononga," tsamba lawebusayiti la University of Iowa likuwonjezera.

Popeza bungwe la US Occupational Health and Safety Administration (OSHA) linakhazikitsa lamulo loletsa mphamvu zoopsa (lock/list) mu 1989, mafakitale ambiri akhazikitsa mapulogalamu oletsa mphamvu a LOTO. Koma nthawi zambiri izi zimayang'ana kwambiri mphamvu zamagetsi ndi makina oopsa; malinga ndi IIAR, makampani a HVAC&R sakhala ndi chidziwitso chokwanira pa kutsegulidwa mwangozi kwa ma valve amanja, zomwe zimapangitsa kuti ammonia ituluke.

Buku latsopanoli likufuna "kudzaza kusiyana kwa makampani" ndikupatsa eni ake ndi ogwiritsa ntchito ma valve amanja a R717 upangiri wabwino kwambiri wamomwe angagwiritsire ntchito mapulani owongolera mphamvu.
