[Sneap] SF6 information

[Chris Westerfeldt]

Bob,
    Our FN typically only has about 5% maximum SF6 in the mix.  We do not
have an emergency exhaust system.  There is a fresh air
supply and a hood exhaust  in the accelerator bay, but that is all.  We do
not have oxygen deficiency monitors in the trench ­ although I have thought
about putting one of those inexpensive ³Halide Hounds² powered by a wall
wart down there to alert us if any SF6 pools down there.
We do have a personnel Oxygen deficiency monitor that can be work on tank
openings or trench entries.
