You've got real problems--let me know where you're working with this stuff
so I can be in another state --and definitely upwind.

I second what Rob Toreki said but more so.

This stuff has a flash pt. of -4F, -20C
So it is very flammable.

It is classified by various folks as a carcinogen.  I do not know how they
know that since it is SOOOO acutely toxic.  Besides I seem to remember that
it will plate out in your lungs so you'd sufocate before it killed you by
other means--but that may be a rumor.

Realize that the TLV is about 0.05 ppm.  Lab hoods pass the ASHRAE test if
they contain 0.1 ppm (for SF6, but this is dense stuff and will tend to flow
out of the hood).  Does your hood have cross drafts, when was it last
checked, how and by whom, etc., etc.  This stuff has bad warning properties,
i.e., if you can smell it, you HAVE BEEN exposed and possibly already
dead-so monitor your pulse.  Rob gave you good warnings about your
hood--most hood suck and not well--so have yours checked out by a safety
professional who knows what they are doing and what you are using and how.

When I worked with flammable and horribly smelly secondary phosphines I used
Br water in a gas dispersion bottle and bubbled the effluent thru that.
Rob has a good idea for a scrubber--use it and use a little chemistry to
figure out how to protect yourself.  Think and re-think.

Ultimately you are responsible for your safety and it is your responsibility
to know the limits of your hood and other equipment and the processes and
materials you are using.

Good luck,

Doug Walters

I'm hoping that one or more of you are willing to share with me your SOPs
for use of this material.
