Ventilation measures to protect the passive smoker. Luftungsmassnahmen zum Schutze der Passivraucher.

Treats laboratory and field investigations indicating the danger to health of non-smokers of inhaling tobacco smoke (passive smoking),to the extent that measures to protect the passive smoker are recommended at 1.5 ppm of carbon monoxide concentration caused by smoking and deemed necessary from 2 ppm. Calculations show that in a state of equilibrium a fresh air supply of 33 m3 per hour and per cigarette smoked is needed to maintain the upper limit of 2 ppm carbon monoxide concentration caused by tobacco smoke. On the basis of these data derives recommendations for the ventilation of rooms with varying loads from tobacco smoking.
