David, 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.
