SUBJECT: Indoor Air Quality (IAQ) Assessment
Portable 164N, 622P, 873C, 1105PK, 1117PK
On August 17, 2007 I conducted a follow-up assessment of Portable 164N, 622P, 873C, 1105PK and 1117PK at
West Hollywood Elementary School. The assessment consisted of a reevaluation walkthrough of the
previously identified area to assess the current condition of the location with regard to indoor air quality. This
assessment included reviewing previously generated work orders as well as observation of the area of concern
as stated in the IAQ Assessments performed on April 27, 2007. Attached are the findings of this assessment
along with recommendations for further assessment, remediation, or corrective actions, if needed.
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 754-321-3200.
