This is a good point.
While polyurethane foams can be cut with a hot wire, it would be inadvisable
to do so without very good ventilation and breathing apparatus as they do
release copious amounts of poisonous fumes.  One thing to watch out for is
just how fast that 2 part expanding foam takes off, a little goes a looooong
way. If you really want a good laugh, mix 200ml (8Oz) of each  in an ice
cream bucket and put it on the floor of an old car (with windows intact) and
shut the door.... 
Cheers.
