Does the same apply to volunteer fire departments and rescue squads that hold bingo games in their facility?
No. Volunteer fire departments and rescue squads are not private clubs. If they serve food, the law applies and they must either prohibit smoking or comply with the law by modifying the structure so the smoking area is structurally separate from the non-smoking areas and vent the smoking area to prevent re-circulation of air from the smoking are into the non-smoking area.
