A study was made by the National Bureau of Standards to evaluate the effectiveness of a smokeproof stairwell tower installed in a highrise apartment building. Tests were also made of photoelectric-type corridor smoke detectors. A quantitative experimental technique of smoke simulation and smoke movement measurement was used. Factors diminishing the effectiveness of the stair towers, preventing smoke infiltration and limiting the response of the detectors, are noted.
