Abstract A panel of ventilation experts assembled by OSHA and ACGIH concluded that dilution ventilation, used in virtually all mechanically ventilated buildings, will not control secondhand smoke in the hospitality industry (e.g., restaurants, bars, casinos). The panelists asserted that a new and unproved technology, displacement ventilation, offered the potential for up to 90% reductions in ETS levels relative to dilution technology. However, this assertion was not substantiated by any supporting data. Air cleaning was judged to be somewhere between dilution and displacement ventilation in efficacy, depending on the level of maintenance. The panel also failed to quantify the ETS exposure or risk for workers or patrons either before or after the application of the new technology. Panelists observed that building ventilation codes are not routinely enforced. They also noted the lack of recognized standards for acceptable ETS exposure as well as the lack of information on typical exposure levels. However, indoor air quality standards for ETS have been proposed in the scientific literature, and reliable mathematical models exist for predicting pollutant concentrations from indoor smoking. These proposed standards and models permit application of an indoor air quality procedure for
