Hi Cindy & all
        Would your scuba experiences apply to a different kind of situation?
A friend of mine is a fireman assigned to Hazardous Materials, and we were
talking about their recent computer aquisition on board their response
vehicle.  He was describing the difficulty of wearing the HazMat suit and
assessing a scene.  One thing they have been wondering about is, how feasible
would it be to use a digital camera or video camera to go in and do the
initial survey, then come back out to the command center and review the photos
while deciding the strategy of the cleanup?
        The issues involved are
        1) It is difficult to  see  well out of the double visors of their suits
        2) Many chemical names are so long, that a snapshot of a barrel could give
them good info, including the chemical name.  But, how hard is it to use a
viewfinder and push buttons with suits on?
        3) Due to contamination issues, especially with vapors, what kind of
containers would protect the cameras, so that they wouldn't have to dispose of
or decontaminate the cameras?
        Do any of these problems relate to the ones you've dealt with in underwater
photography?
        I appreciate your thoughts-
Darcy
