Hello Debbie,
Several years back during a renovation of an older laboratory, plumbers wer
e cutting out vacuum lines with a reciprocating saw when a small explosion/
flash occurred.=C2=A0 Fortunately no one was hurt.=C2=A0 We were not able t
o determine the contaminant that may have caused the incident.=C2=A0
As a result of that incident, future vacuum line demolitions are preceded b
y taking a sample of the line using a manual tube cutting tool.=C2=A0 They
also use the manual tube cutter for the demolition of the vacuum lines.=C2
=A0 The sample is then sent out for analysis.=C2=A0 Some of the samples hav
e resulted in high levels of certain regulated metals requiring disposal as
hazardous waste.

tell them to flush out the lines with hot soapy water,rinse thoroughly
and then set about whatever they need to do toremove/reconfigure the vac

Hello Debbie,
Several years back durin
g a renovation of an older laboratory, plumbers were cutting out vacuum lin
es with a reciprocating saw when a small explosion/flash occurred. Fo
rtunately no one was hurt. We were not able to determine the contamin
ant that may have caused the incident.
As a result of that in
cident, future vacuum line demolitions are preceded by taking a sample of t
he line using a manual tube cutting tool. They also use the manual tu
be cutter for the demolition of the vacuum lines. The sample is then
sent out for analysis. Some of the samples have resulted in high leve
ls of certain regulated metals requiring disposal as hazardous waste.
