Dear Mr. Orlan:
ATC Associates Inc. (ATC) is pleased to provide this report of indoor air quality (I.A.Q)
measurements collected on April 29, 2002, at the referenced school. The New York City Board
of Education (BOE) requested these measurements as part of a program to determine if
acceptable indoor air quality is being maintained.
SCOPE OF WORK
ATC conducted this evaluation to assess the basic parameters of temperature, relative humidity.
carbon dioxide (CO,) and carbon monoxide (CO).
Total volatile organic compounds (TVOCs) and respirable particulates were also measured.
Kevin Fitzpatrick, Environmental Technician of ATC’s New York City office, conducted the
assessment. ATC’s findings are based on a visual inspection, real-time environmental
measurements and conditions present in the school at the time of the assessment.
ATC measured temperature, relative humidity, COj and CO with a Q-Trak® Model 8551,
manufactured by TSI, Inc.
ATC measured concentrations of respirable particulates (PM2,5) with a Dust-Trak® Aerosol
Monitor Model 8520, manufactured by TSI, Inc.
ATC measured concentrations of TVOCs using a RAE Systems, Inc. Mini RAE® photoionization
detector (PID).
The assessment was performed consistent with generally accepted indoor air quality assessment
practices. As with 2.11 such assessments, there were inherent limitations created by constraints of
time, operational and work practice variability, variations in indoor air quality parameters and
sampling and analytical accuracy.
