Hot air guns are like any other tool - they can be dangerous! I've got an older Black and Decker version, and you most certainly wouldn't want to try drying your hair with it - it gets mighty hot!
You can scorch the wood if you leave it running on the same spot for very long, just like a blowtorch would. And when you put it down, remember that the nozzle is going to be well hot too - so easy to brush your hand against it and get burnt.
Have you thought of a blowtorch instead? Just a thought - the hot air gun is a bit expensive to run as I recall, and not so configurable in terms of what comes out at the sharp end - with a blowtorch you can change the size of the flame.
