Yog tias muaj cov paib no tshwm sim, tsis txhob siv lub tank tam sim ntawd, khiav tawm ntawm thaj chaw yog tias muaj roj tsw qab, hu rau 911 los ntawm sab nraud, thiab tiv tauj koj tus neeg muag khoom propane rau kev kuaj xyuas lossis hloov pauv. Tank uas raug tswj xyuas kom zoo, tshuaj xyuas tsis tu ncua, thiab nyob rau hauv lawv lub sijhawm tsim nyog muaj kev nyab xeeb tshwj xeeb.
Kab hauv qab
Qhov sib txawv ntawm lub tank propane tawg yog kwv yees li 1 ntawm 3.7 lab toj ib xyoo - qis dua qhov txawv ntawm kev raug xob laim - thiab thaum tawg tau tshwm sim, lawv yuav luag ib txwm tshwm sim los ntawm qhov tshwj xeeb, tiv thaiv tau zoo li hluav taws xob ncaj qha, tag nrho overfilling, hnyav unchecked corrosion, los yog tsis muaj kev siv cov khoom siv kev nyab xeeb.Propane tso tsheb hlau luam yog cov feem ntau ua tib zoo tsim thiab rov ua kom muaj kev nyab xeeb hauv cov neeg siv khoom siv ntau, nrog rau lub siab nyem li qub, cov khoom siv tiv thaiv overfill, tawg - tiv thaiv kev tsim kho, thiab cov sij hawm yuav tsum tau soj ntsuam uas ua rau muaj kev puas tsuaj rau lub tank tsis ua haujlwm hauv kev siv ib txwm ua tsis tau zoo. Hom "explosion" uas neeg feem coob ntshai - propane tank rupturing zoo li lub foob pob - yog li tsis tshua muaj nyob rau hauv tiag tiag - ntiaj teb no propane siv hais tias nws yog ib qho tseem ceeb tsis yog - tshwm sim nyob rau hauv cov neeg siv khoom. Qhov kev pheej hmoo tiag tiag thiab ntau dua yog cov roj tsub zuj zuj hauv cov chaw kaw, uas tiv thaiv tau tag nrho los ntawm kev ua pa kom raug, kev teeb tsa roj av, thiab cov lus teb tam sim rau cov pa tsw phem. Cov kev coj ua uas ua kom cov propane tank tawg qhov sib txawv ze rau xoom yog qhov yooj yim thiab tus qauv: tsis txhob overfill, ua kom lub tank ncaj, tshuaj xyuas kev sib txuas txhua xyoo, khaws cov cylinders sab nraum zoov hauv qhov cua, teeb tsa cov khoom siv roj, thiab teb tam sim ntawd rau cov roj tsw qab. Cov kev coj ua no yuav tsum tsis muaj cov cuab yeej tshwj xeeb, tsis muaj kev teeb tsa kev tshaj lij, thiab tsis muaj nqi txuas ntxiv - lawv tsuas yog tus cwj pwm ntawm lub luag haujlwm ntawm kev siv propane, thiab lawv yog dab tsi ua rau propane yog ib qho kev nyab xeeb tshaj plaws rau kev siv hauv tsev thiab kev ua si.
