If it was gas, it could still be cut up. But you have to clean it out and then fill it completely with water and let it sit a little while. Water will displace any gas and anything left wont be enough to do anything. I would then cut it up leaving the water in it.
Something about gas vapor has to be greater than 2% and less than 10% to make it explode in air.
I think I would rather use water than nitrogen gas.
