it would be nearly impossible to make an estimate just based on the information you shared. there are no equations or scales that have ever been developed to get pack equivalences from second-hand smoke in closed environment like you describe. needless to say. she is very exposed and it is a well-established fact that second hand smoke just in a home environment could be equivalent to smoke a 1/2 pack of cigarettes per day. she is likely to be getting more exposure than that. cigars produce more smoke and that smoke is just as risky as being downwind from a cigarette. even third-hand smoke -- the chemicals that stick to her clothing and hair are known to be a health risk. as a militant anti-smoking health professional that is not a place that i would want any loved one to work. i guess wearing a respirator at work is out of the question and would be bad for business!
how much second hand smoke do you breathe at an average cigar bar? . my significant other works 3 days a week at a cigar bar each shift 10-12 hours. the place is ventilated but still somewhat smokey throughout the day. as a non-smoker i am highly concerned about the amount of chemicals she is breathing throughout the day. what are the real risks associated with this work environment? there are roughly 25 cigars smoked per hour in about 1800 sq feet. about how many equivalent packs of cigarettes a day is she taking in second hand as a form of measurement?
