Ventilation Can’t Eliminate The Health Risks
Recirculation of air through a building’s ventilation system results in ETS from a smoking area appearing in nonsmoking areas as well.41
Steve Taylor, Chairman of ASHRAE Standard 62, had this to say about the new 1996 Standard 62R: “We don’t explicitly say, ‘Thou shalt not smoke’ What we do say is that the ventilation rates are based on spaces where smoking does not take place. So I guess indirectly you could say that you can’t comply with the standard if smoking does take place. Given that EPA and others consider environmental tobacco smoke to be a carcinogen, we have difficulty addressing how you can have comfortable indoor air quality in the presence of carcinogens.”42
ASHRAE recently issued a new, stronger standard for indoor air ventilation. This new standard—ASHRAE 62-1999—is based on a totally smokefree environment.43 Nevertheless, the tobacco industry continues to promote the older AHSRAE Standard 62-1989 as adequate for controlling exposure to secondhand smoke.44 45
