2015 IBC is the any proabortion of a mullion in a 72 inch door for any use group, especially A-2?
No. If you have a two 36-inch door leaves in a single opening with no mullion, the egress width is approximately 67-68 inches. In that same opening, if you put a 2-inch mullion, the egress width is reduced by 2 inches to 65-66 inches.Don't you mean "will not" reduce?

That is true, however, nowhere does the 2015 IBC or the MA amendments define night club different from other A-2 uses. In the 8th edition, MA did amend the code to include a definition of night club, this is not four in the current 9th editionCheck it against the actual MASS. Building code::

MA 8th edition amendment
303.1.1 Definitions.
NIGHT CLUB. An occupancy generally characterized by a combination of any of the
following: no theatrical stage accessories other than raised platform; low lighting levels;
entertainment by a live band or recorded music generating above-normal sound levels; later-than
average operating hours; tables and seating arranged or positioned so as to create ill defined
aisles; a specific area designated for dancing; service facilities for alcoholic beverages with
limited food service; and high occupant load density.
So now the next morning and I am making an appointment with my eye doctor and a reading specialist. As CDA pointed out the definition I was lookin for is in our amendments chapter 2 a clear definition of night club.
Thanks to all for the help and input
