Hint: Getting the flamethrower:
Climb the first set of stairs, then stand next to the left side bookcase. Walk behind the bookcase to enter a room. Use the door to leave and go outside. Move down to find flamethrowers on each side of the building. Go to the pistol box and switch to the flamethrower.
