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.

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.
