Cigarette smoke in enclosed public facilities

J Sebben, P Pimm, R J Shephard

    Archives of Environmental Health
    |March 1, 1977
    PubMed
    Summary

    Carbon monoxide (CO) levels in public venues like nightclubs were measured. Nightclubs showed the highest CO concentrations, indicating poor air quality from smoking.

    Area of Science:

    • Environmental Health
    • Occupational Safety
    • Public Health

    Background:

    • Carbon monoxide (CO) is a harmful gas produced by combustion.
    • Indoor air quality in public spaces can be affected by various sources, including smoking.
    • Elevated CO levels may indicate the presence of other harmful smoke constituents.

    Purpose of the Study:

    • To measure carbon monoxide concentrations in various enclosed public facilities.
    • To identify public venues with the highest CO levels.
    • To establish safe CO concentration limits as an indicator of cigarette smoke.

    Main Methods:

    • Utilized a portable carbon monoxide detector with a catalytic electrode.
    • Recorded CO concentrations in diverse public settings: nightclubs, bars, restaurants, stores, hospitals, and public transit.
    • Compared indoor CO readings with outdoor ambient levels.

    Main Results:

    • Nightclubs exhibited the highest average indoor CO concentrations (13.4 ppm), significantly exceeding outdoor levels.
    • One poorly ventilated venue recorded CO levels ranging from 20 to 40 ppm.
    • Recommended that CO concentrations should not exceed ambient readings by more than 5 ppm to indicate safe air quality regarding smoke.

    Conclusions:

    • Enclosed public facilities, particularly nightclubs, can accumulate significant levels of carbon monoxide.
    • Ventilation and employee health screenings are crucial for mitigating risks associated with indoor air pollutants.
    • Carbon monoxide monitoring can serve as a valuable indicator for assessing the impact of cigarette smoke in public indoor environments.
