1) The pyrophoric residue in the syringe should be neutralized by
rinsing with water, an alcohol or acetone.
2) I never use plastic syringes as I would never trust the plastic to
not be dissolved by the reagent or melt if a fire did occur. I always use glass
syringes.

I have a question from our Chem dept about nButyl Lithium &
syringes after I forwarded them the CEN blog on safer syringes. http://cenblog.org/the-safety-zone/2013/02/engineering-safer-syringes/
The lab's SOP calls for not reusing their syringes & only filling
them 50%. I asked them to write in more clearly that they are to dispose in
sharps container.
The questions I'm hoping any of you with similar hazards can help with:
1. Is there enough residual material in the syringe that it could be
hazardous?
2. Should there be a sharps container stored in the fume hood for the
exclusive use of these syringes (avoiding incompatible material that may be
left in the syringe)
3. If not a sharps container, what/how does your labs dispose of these
syringes?
thanks!
