Re: Indoor Air Quality Assessment High School of Economics and Finance (M833) 100 Trinity Place New York, New York 10006 ATC Project No. 15-19125-0291
Dear Mr. Orlan:
ATC Associates Inc. (ATC) is pleased to provide this report of indoor air quality (lAQ) measurements collected on March 8, 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.
Prasad Doddapaneni, Environmental Technician, of ATC’s New York City office, conducted the assessment. ATC’s findings and conclusions 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, CO- 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. MiniRAE® photoionization detector (PID).
The assessment was performed consistent with generally accepted indoor air quality assessment practices. As with all 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.
