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.

Subject: [DCHAS-L] Butyl Lithium & syringe safety


I have a question from our Chem dept about nButyl Lithium & syringes after I forwarded them the CEN blog on 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?
