Hi Kurt!
The filling room had a lead-lined floor to prevent sparks (... which would result in a very bad day!) Immediately aft would be a bulkhead with glass windows. The light room had a lantern in it to work by and had a vestibule with a separate entrance from the filling room and powder room. The light room was strictly isolated from anywhere there might be gunpowder.
