Recommendations p. 21:
We recommend eliminating tobacco from the casinos and implementing a smoking cessation program. The casinos should also eliminate smoking near building entrances and air intakes to protect employees from involuntary exposure to ETS. A physician should evaluate employees with respiratory symptoms, especially symptoms related to asthma that are associated with workplace exposures.
