Xauv tawm tag tawm-Safety Operation Guide

Cov ntaub ntawv no yog txhawm rau txo qis kev sib tsoo ntawm phau ntawv li qub hauv ammonia tub yees tshuab.

Raws li ib feem ntawm txoj kev tswj hwm lub zog, lub koom haum International Ammonia Refrigeration Institute (IIAR) tau tshaj tawm cov lus pom zoo los tiv thaiv kev sib tsoo ntawm phau ntawv li qub hauv ammonia (R717) tub yees tshuab.

Thawj version ntawm qhov kev thov-Cov Lus Qhia rau kev tsim cov phiaj xwm tswj hluav taws xob rau phau ntawv li qub hauv ammonia tub yees tshuab-IIAR cov tswv cuab tuaj yeem yuav nws rau $ 150, thiab cov neeg tsis yog tswv cuab tuaj yeem yuav nws rau $ 300.

Kev tswj ntawm phau ntawv valve belongs rau kev tswj hwm lub zog txaus ntshai, uas feem ntau hu ua lockout / tagout (LOTO) txheej txheem.Raws li University of Iowa Ib puag ncig Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb lub vev xaib, qhov no tuaj yeem tiv thaiv cov neeg ua haujlwm los ntawm kev raug mob lossis raug tua los ntawm kev ua kom yuam kev lossis tso tawm lub zog khaws cia thaum tswj thiab kho cov tshuab, txheej txheem, thiab cov tshuab.

Lub zog phom sij tuaj yeem yog hluav taws xob, hydraulic, pneumatic, mechanical, chemical, thermal, lossis lwm qhov chaw."Ua raws li LOTO cov kev coj ua thiab cov txheej txheem tsim nyog tuaj yeem tiv thaiv cov neeg ua haujlwm los ntawm kev tso tawm hluav taws xob tsis zoo," University of Iowa lub vev xaib ntxiv.

Txij li thaum US Occupational Health and Safety Administration (OSHA) tau tshaj tawm txoj cai tswj kev phom sij txog hluav taws xob (xauv / daim ntawv teev npe) hauv xyoo 1989, ntau lub lag luam tau siv LOTO cov kev tswj xyuas hluav taws xob.Tab sis cov no feem ntau yog tsom rau hluav taws xob txaus ntshai thiab lub zog siv tshuab;Raws li IIAR, HVAC & R kev lag luam tsis muaj qhov pom tseeb ntawm kev sib tsoo ntawm cov ntawv qhia li qub, uas yog qhov ua rau muaj ntau cov ammonia leaks.

Cov lus qhia tshiab no tsom mus rau "sau qhov sib txawv ntawm kev lag luam" thiab muab cov tswv thiab cov tswv lag luam ntawm phau ntawv R717 phau ntawv li qub nrog cov lus qhia zoo tshaj plaws txog kev siv cov phiaj xwm tswj hluav taws xob.
