Funga tagi-Ubuyobozi bukoresha umutekano

Iyi nyandiko igamije kugabanya gufungura impanuka zifungura intoki muri sisitemu yo gukonjesha ammonia.

Muri gahunda yo kugenzura ingufu, Ikigo mpuzamahanga cyo gukonjesha Amoniya (IIAR) cyatanze ibyifuzo byinshi byo gukumira impanuka zifungura intoki muri sisitemu yo gukonjesha ammonia (R717).

Igice cya mbere cyifuzo-Amabwiriza yo guteza imbere gahunda yo kugenzura ingufu za valves muri sisitemu yo gukonjesha ammonia-abanyamuryango ba IIAR barashobora kuyigura ku madolari 150, naho abatari abanyamuryango bakayagura ku madolari 300.

Igenzura ryintoki ni iyigenzura ryingufu ziteje akaga, ubusanzwe bita uburyo bwo gufunga / tagout (LOTO). Nk’uko urubuga rwa kaminuza y’ubuzima bw’ibidukikije n’umutekano rwa kaminuza ya Iowa rubitangaza, ngo ibyo birashobora kurinda abakozi gukomereka cyangwa guhitanwa n’impanuka zitunguranye cyangwa kurekura ingufu zabitswe igihe cyo kubungabunga no gusana imashini, inzira, na sisitemu.

Ingufu zishobora guteza amashanyarazi, hydraulic, pneumatike, ubukanishi, imiti, ubushyuhe, cyangwa izindi nkomoko. Urubuga rwa kaminuza ya Iowa rwongeyeho ruti: "Gukurikiza imikorere n'ibikorwa bya LOTO birashobora kurinda abakozi gusohora ingufu."

Kuva muri Amerika Ikigo gishinzwe ubuzima n’umutekano muri Leta zunze ubumwe za Amerika (OSHA) cyashyiraho amategeko agenga ingufu zangiza (gufunga / urutonde) mu 1989, inganda nyinshi zashyize mu bikorwa gahunda yo kugenzura ingufu za LOTO. Ariko ibi bikunze kwibanda ku mbaraga z'amashanyarazi na mashini; nk'uko IIAR ibivuga, inganda za HVAC & R ntizisobanutse neza ku gufungura ku buryo butunguranye gufungura intoki, bikaba ari byo bitera amoniya menshi.

Ubuyobozi bushya bugamije “kuziba icyuho cy’inganda” no guha ba nyir'ibikorwa n’abakoresha intoki za R717 n’intoki inama nziza zuburyo bwo gushyira mu bikorwa gahunda yo kugenzura ingufu.
