Thanks every one for the comments.  To answer other questions raised during
the discussion:

1.      No, we are not considering sprinklers in the hoods.  And,

2.      Yes, the area is currently equipped with two rather large Class D
extinguishers.


The comments from all in regards to Metal-X an Lith-X are especially
appreciated.  We hadn't considered this and will thus check on the
appropriateness of the agent in the Class D extinguishers.  And, I greatly
appreciate the comments from LANL concerning the protection of storage and
cutting labs.  This should help with the faculty member's request to know
what large national labs are doing.
