Stop here and make a fume cabinet. It is real easy and will prolly preserve you a day or two longer...
Take two auto A.C. blowers that are encased in a houseing, seal all the seams with epoxy. Get an old bead blasting cabinet that is stripped, and mount new safety glass (w/a lexan layer to the outside) to the top of the cab, cut holes for the vac opening of the blowers, mount w RTV (fat bead) fashion ducting, (heavy dryer exaust duct works good, you can give each thier own exaust, but put a balance tube between) The exaust fans being D.C. gives an optional battery back-up ability if you want to keep cooking during the hurricane. Judiciously make some intakes, but calculate the area of the holes, to the fans vacuum potential, so that you develop a slight neg. pressure inside the cabinet. If you have some real goliath exhaust fans, you wouldn't need to mount gloves on the cab. (but then you would have that 'whys them lil cuts on my hands STINGING?') The other option is to provide a pos. pressure from under, exhaust through the top. This works good if you have 'heavy' gasses developing anywhere along the way...
Bromide gases/compounds heavy? yes-no???
anyway, save the sacs, AIR SACS that is...
floating on a gyroscope, thumbing our nose at the universe, what a ride!
