Kevin,

 

Bud Wasserot, an ES owner on my field, had an "extra" door due to some warping.  He was in a unique position to test different tools on his window.  I know the ES door glass is thinner than the IVP glass. Even so, one of those little emergency hammers didn't even dent the window glass.  Bud ended up buying a ball pein hammer and grinding the rounded end to a point.  That tool was able to break through the window glass.  I'm not sure what size tool would be necessary to break through an IVP window.

 

How does HPAT address the door in their training?
