SUBJECT: Indoor Air Quality (IAQ) Assessment
FISH 501, 502, 502A, 502B and 503
On August 17, 2007 I conducted an assessment of FISH 501, 502, 502A, 502B and 503 at Deerfield Beach Middle
School. This evaluation included observations of the flooring system, ceiling tiles, false ceiling plenum,
environmental surfaces, interior and exterior walls, and the accessible ventilation equipment. Additionally,
environmental parameter measurements were taken to include temperature, relative humidity, and carbon
dioxide. The detailed findings, along with the recommended corrective action can be found on the attached
IAQ Assessment Worksheets.
The IAQ assessment did identify one or more existing conditions impacting IAQ and has generated appropriate
work orders to correct deficiencies in systems and maintenance that could contribute to decreased indoor air
quality. At the time of the assessment, these concerns were not an immediate health or safety concern 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.
Please ensure that your Head Facilities Serviceperson receives a copy of this correspondence so that the
recommendations requiring their attention can be addressed. Within two weeks a representative from the
Custodial/Grounds Department will conduct a follow-up visit to ensure that all issues have been appropriately
addressed.
Should any questions arise, or if the current concerns continue after the attached recommendations have been
addressed, please feel free to contact me at 754-321-1638.
