That's the wrong question, SheLion. You want to know the "standard" for air exchange in a smoking-permitted area, right? Unless such a standard is specifically written into a municipal code or legislation, there isn't one. Remember, the antis say sonorously "there is no safe level of shs." Now there WAS a study of how well-ventilated smoking-permitted restaurants compared with smoker-hostile restaurants in the same mall, and to the consternation of the antis, the smoker-friendly places had cleaner air. I'll find that one for you, even though it isn't exactly what you're looking for.

Max: Thanks so much for answering this question. I have a gal in NH that is attending a "town meeting" tomorrow about an up and coming ban, and she and her husband are going to attend to help fight it.

"Can you help with this one. Am I correct in my analysis:

"For cocktail lounges, up to 30 cubic feet per minute of outdoor air per occupant shall be provided for 100 people per 1,000 square feet." This language can be construed to require 18 whole room air changes per hour for a 20wide x 50 long x 10 high lounge

Is this a reasonable number of air changes?"
