SUBJECT: Indoor Air Quality (IAQ) Assessment
FISH 704, 705, 706 and 707
On August 15, 2005 the IAQ Assessment Team conducted an assessment of FISH 704, 705, 706 and 707
at Bennett Elementary School. The evaluation consisted of a walkthrough of the identified areas to
assess the current condition of the location with regard to indoor air quality. This assessment
included observations of the carpet, floor tile, ceiling tile, interior walls, false ceiling plenum, and
accessible ventilation equipment.
Attached are the findings of this assessment along with recommendations for further assessment,
remediation, or corrective actions, if needed.
Generally, the IAQ Assessment did not identify any existing conditions significantly impacting IAQ
and thereby presenting immediate health and safety concerns to building occupants. However, due to
individual sensitivities and predisposing health factors, it is possible that some building occupants
may elicit a health response to agents and / or conditions identified during the evaluation. Therefore,
to further improve IAQ, prevent development of future IAQ-related problems, and to reduce the
potential for IAQ-related complaints by building occupants, the IAQ Assessment Team recommends
appropriate follow up of each item identified and listed in the attached evaluation.
Should any questions arise, or if the current concerns continue after the attached recommendations
have been addressed, please feel free to contact me at 754-321-3200.
