Is there a state code covering fire sprinklers in kiln rooms?
I guess this would depend on which of the 50 states you were in.
Are fire sprinklers required in electrical switch gear rooms per electrical codes and if present are they required to be removed?
In macro terms, the "tax code" is the entire body of laws and regulations covering who pays how much tax on what. In the United States, the tax code is a complex piece of legislation covering multiple volumes of law tomes; lawyers who choose to practice in the area of the tax code tend to subspecialize in areas like individuals being prosecuted for backtaxes or filing for corporations.
