Dear Mr. Orlan:
ATC Associates Inc. (ATC) is pleased to provide this report of indoor air quality (lAQ) measurements collected on April 16, 2002, at the referenced school. The New York City Board of Education (BOE) requested these measurements to evaluate air quality in the school building prior to re-occupancy.
SCOPE OF WORK
ATC conducted this evaluation to assess the basic parameters of temperature, relative humidity, carbon dioxide (CO,) and carbon monoxide (CO).
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 Total Volatile Organic Compounds (TVOCs) using a RAE Systems, Inc. MiniRAE® photoionization detector (PID).
Mr. Jimmy Choy, 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.
