Hello everyone,

I have been asked about a respirator that is sufficient to protect pregnant 
lab employees from xylene vapors.  Do any of you have any recommendations or 
experience using respirators for this purpose?

This is a general question as I am not aware of the ppm present in the lab 
in question, although I am told the fumes are pretty strong.  The lab I work 
in uses a xylene substitute so this has not been an issue.

Any advice would be greatly appreciated.

Thank you,

Louri Caldwell
