Sorry this took so long to answer... We really only have our ethics policy with city which is fairly standard.
I would condisder a few things when writing. If you are representing the Fire Department that raises the bar in how you conduct yourself, what you say and the implications of your content. This shouldn't be a problem unless you are trying to be controversial and then you should probably just submit it as your own stuff without department mention.
If the writing is does on your own time, does not cost city money and/or bring a bad light on the department, you should have no problem. Don't use a picture in uniform if you have any question about whether the content of your article will be problematic.
Hope some of this helps... Please do write, do share your ideas, do give us your experiences... We need them...
