A hospital ward and an operating room were disinfected by disseminating beta-propiolactone BPL in a concentration of one gal. of BPL for each 12,000 to 16,000 cu. ft. of space. The temperature was elevated to 74F. and the relative humidity to 75 per cent, the supply and exhaust ventilation systems were turned off, and all seams and openings were blocked before BPL was disseminated. It was possible to enter the disinfected areas after two hours of forced aeration. However, overnight aeration is advisable whenever BPL is used. The efficacy of BPL disinfection was determined by seeding areas with spores of Bacillus subtilis var. niger. No B. subtilis was recovered from these areas following disinfection.
