Riskofseriousinjuryposedbypressurizedcomponentsmovinginanuncontrolledmanner
whenhandledimproperly. 
Ifnothandledproperlyorintheeventofadefect,gascanescapefrompressurizedcompo‐
nentsunderhighpressureandcauseseriousinjuriesandevendeath.Beforeyoustartwork‐
ingonthesecomponents:
 Closeallconnectionsleadingtothegas‐carryingline.
 Establishadepressurizedstatus.Residualamountsofenergymustbedepressurizedas
well.


Riskofinjuryposedbyburstingpartsintheeventthattheyaresubjectedtopressurein
thewrongdirection
Thedevicehasbeendesignedforaspecificdirectionofflow,whichislabeledonthedevice.
Subjectingthedevicetopressureinthewrongdirectionmayresultinseriousinjurycaused
byburstingparts.
 Pressurizethesystemonlyontheinletside.
