Gwaro iri rine chinangwa chekudzikisira kuvhurwa kwetsaona kwemavharuvhu muammonia mafiriji masisitimu.
Sechikamu chechirongwa chekudzora simba, International Ammonia Refrigeration Institute (IIAR) yakapa nhevedzano yekurudziro kudzivirira kuvhurwa netsaona kwemavharuvhu emagetsi muammonia (R717) masisitimu efiriji.
Yekutanga vhezheni yechikumbiro-Nhungamiro yekugadzira masimba ekudzora zvirongwa zvemavharuvhu muammonia refrigeration masisitimu-IAR nhengo dzinogona kuzvitenga nemadhora zana nemakumi mashanu, uye vasiri nhengo vanogona kuzvitenga nemadhora mazana matatu.
Kudzora kwevhavhavha yebhuku ndeyekutonga kwesimba rine njodzi, iro rinowanzo kunzi iyo yekuvhara / tagout (LOTO) maitiro. Zvinoenderana neYunivhesiti yeIowa Environmental Health uye Safety webhusaiti, izvi zvinogona kudzivirira vashandi kubva mukukuvadzwa kana kuurayiwa netsaona activation kana kuburitswa kwesimba rakachengetwa pakuchengetedza nekugadzirisa michina, maitiro, uye masisitimu.
Simba rine njodzi rinogona kunge riri remagetsi, hydraulic, pneumatic, mechanical, chemical, thermal, kana mamwe manyuko. "Kutevera maitiro akakodzera eLOTO uye maitiro anogona kudzivirira vashandi kubva pakuburitswa kwesimba rinokuvadza," webhusaiti yeYunivhesiti yeIowa inowedzera.
Sezvo US Occupational Health and Safety Administration (OSHA) yakadzika mitemo ine njodzi yekudzora simba (lock/list) muna 1989, maindasitiri mazhinji akaita zvirongwa zveLOTO zvekudzora simba. Asi idzi dzinowanzonangana nesimba remagetsi nemagetsi rine ngozi; maererano neIIAR, iyo indasitiri yeHVAC&R haina kujeka pakuvhurwa netsaona kwemavharuvhu emaoko, chiri chikonzero chekudonha kwakawanda kweammonia.
Nhungamiro itsva ine chinangwa che "kuzadza gap remaindasitiri" uye kupa varidzi nevashandisi vebhuku reR717 mavharuvhu emaoko ane mazano ekushandisa mazano ekushandisa zvirongwa zvekudzora simba.
